Okay, first thing to mention is that I have searched for information on my issue and while I have found (and tried) solutions that approach my goof, I need to post this:
Last night I finished reading from Kindle app, hit the power button to shut off the screen and laid it down. I know I should have plugged it to recharge but too late now. I am running CM nightly from 07172012, so I know I didn't download the nightly CM battery issue versions.
This morning the screen will not light up; I have tried charging it, hard reset with power and home screen buttons for 15-20 seconds (and longer), and nothing works. My concern is that the screen is dead. I connected the touchpad to my laptop and I get the connection sound from the laptop; it sees the TP but does not accept it as a portable storage device. Device Manager lists it as: QHSUSB_DLOAD with driver(s) not loaded.
When I try the volume rocker button I do not hear the small audible ping as volume goes up or down. Of course, with the resets, who knows where I am in the OS (or even if it is WebOS or Android).
I really didn't want to be a noob and post this, but I need some advice from the brethren here on XDA. Thanks in advance.
It seems to me that it's not even booting if your getting that strange device in device manager. Try the webos recovery tool from hp. It may help. Although it will wipe android off.

my son-in-law is in the same boat. Nothing he does wakes it up. I believe there are tp's out there with this hardware issue. I let my tp battery drain completely. It powers down around 4% battery. I place it on the touchstone, it charges backup and boots into moboot, then webos. I've done this twice. no problems. If it's under warranty still, send it in.
If you have a touchstone charger put it on that and leave it for a couple of hours and it Will come back to life.
See this article by Reverend Kyle http://www.reverendkyle.com/index.php/articles/146-hp-touchpad-charging-issues-solution
I hope this helps.
I've had multiple instances of black screen of death failure.
The latest one I had, I was able to restore by using a standard USB to micro USB cable (and recently NOT the HP OEM cable) to connect to the computer I usually use to sync or use HP web doctor with.
Same symtpom as the OP, get the three dings when connecting the touchpad to the computer, no responses and the QHUSB driver load error. HP charger wouldn't chage it, touchstone would not charge it.
Anyhow, I left it connected for a few hours to charge connected to my PC. Then, I disconnected from the PC using the large USB connector and reconnected. Whamo, got to the bootloader.
I believe what happened was I trickle charged the touchpad enough to get the touchpad to boot.
You can try the various hard boot keypresses too, but wait for a few hours while trying to trickle charge the touchpad via the computer USB.
Update
Okay, so I followed the old rule of doing the simple (and/or free) solutions first and then move on.
1) I set the touchpad on the touchstone for several hours yesterday - no luck
2) I connected the touchpad to my pc through the USB and let it charge - no luck
3) I let it be plugged into the standard charging plug all night - no luck
4) I prayed to the great old god Cthulhu - no luck
My only option remaining is to use WebOS Doctor. One question on that: in all the literature I have read thus far (and perhaps I am mistaken), I need to be able to get the TP into USB mode to download the corrections/reboot back into WebOS. Is that right or can I expect that when the doctor sees the mangled mess of an OS through the USB connection, it will know what to do?
Again, as always that for the previous posts and for the support.

Another piece of black magic that worked for me and is worth a try as it is free. Connect Touchpad to standard HP brick charger plugged into power outlet. Unplug cable from charger, count to 5, plug it back in, count to 5, take it back out. Repeat the cycle until you get bored or until you get a red charging symbol. If you get the latter then let it charge up normally and you are back in business. The theory behind this method is that it takes a few seconds on plugging in for the circuits to realise they "shouldn't be charging" and this allows a little bit of charging to take place on each insertion. Repeat enough times and you get enough to kick start the proper charging. In my case about 20 times did the trick.
As I didn't want to get into this situation again I then set up a Tasker process to power down th eTouchpad if the battey charge dropped below 8% and I've been OK since.
RIP Touchpad / EOT
Well, I had to wait a day to get my hands on a WinXP laptop; I upgraded my Dell to Win8 about 3 months ago and WebOS Doctor does not play well with Win8.
While that time passed, the touchpad finally gave up the ghost. There is no power left in the TP. When I run WebOS Doc the laptop cannot see the TP connecting via USB. I also checked by connecting the TB to the Dell, since it would at least see the device. Not any more.
My thanks again to those that responded. I did try the plug in, plug out with 5 second waits between, just in case. You never know. However, after 50+ attempts I had to call it a no-go.
does your home button light come on at all? Are you able to see moboot bootloader at all or are you able to start the tablet in webos recovery mode by holding the vol key while powering it on? are you able to ./adb connect? Also I've never had much luck with the resest method youre using, holding down the power and home key, I always hold down the power key and press the home key 15 times, when I get hard freezes and lockups, it's always worked.
Mine is in the same boat for a couple of months, removed battery and charged. Boot loader is borked I get only get a qualcomm usb device but nothing thats of any use for webos doctor or qualcomm tools. We'll have to wait until someone figures out jtag or how to replace the bootloader with qualcomm tools. I'm amazed with the number of touchpads out there that something hasn't leaked from hp to fix it. Anyone got friend in hp or qualcomm :angel:
OP Update
Well, I thought this was a dead issue but here is the latest.
After wallowing it a pit of despair the likes of which can only be described as wretched, (I even coveted my wife's TP up close, almost giving into temptation and swapping decals to reverse ownership) I looked outside of XDA and did general Google searches and happened upon this site:
http://forums.webosnation.com/hp-touchpad/299256-dead-touchpad.html
After reading a bit I realized that the touchstone may be able to recharge the dead battery even though fully drained. I began the quest that Friday morning the 24th of August, after verifying that my Dell laptop did not see the TP when plugged in via the USB cable.
I just did a quick check and the laptop now "sees" the TP when connected. Still no luck on booting into Moboot or the USB icon screen - neither Power and Volume Up or Power and Home buttons achieve anything. But I am glad to see that the touchstone has placed enough charge into the battery that the laptop is aware of the TP when connected.
I believe that given a few more days on the touchstone I should be able to boot into moboot.
@ haxin - I have nothing. Not a single light from the Home button - my only evidence that there is SOMETHING going on is when I connect the TP to the laptop and get my connection "sound". Again, I have high hopes that the touchstone will get me where I am going, albeit at a snails pace.
@ paddy - Yeah, I hope that when (if) I get to a lit screen, I am able to move past where you are at. My big concern is that I am toast even with a semi charged or fully charged battery from the touchstone.
I will update later on. Again, thanks to all for the input and probing questions. You have made me think harder and work a bit longer on this project.
OP Update - 31 August
After 7 days on the touchstone, the touchpad is currently showing the low battery charge icon; I have now plugged it into the A/C adapter.
Each morning I have picked up the TP, held down the power button and held the home button for 15+ seconds. Today it worked, turning on the screen for the first time in a week and letting me see the low battery image.
In my quest to resolve this issue, I have read so many variations on what buttons to hold and how long to hold them that after awhile you end up considering the possibility that SOME of the button options are not correct. That the operator has booted their TP up, but they misconstrued the actual solution; how else can you explain the idea that HP built so many different button combinations and hold times to boot a TP from a nearly or fully dead battery state?
Anyway, I will continue to post updates until my beloved TP is back to running CM9.
And to all those who gave their TP up because the battery got too low; find a touchstone or other "trickle" charger solution, connect and let it sit for a week or so.
Thanks!
Glad the Touchstone worked for you , don't know why it has taken so long to charge but when your up an running properly Llama is a good app to install as
A:You can set alarms for when the battery gets to a certain level/levels
B:Have it shut down when the battery gets to a certain level.
I use 20% for an alarm and 10% to shut down which allows me to sleep easy and not worry if someone else is using it . .
I am up and running. I most definitely will load that app on my TP, plus my wife's and a coworker who bought a TP because of mine.
I don't know either why it took so long; I am just glad it worked and I have it back. I am on it right now.
Thanks again to all who provided feedback and guidance. This is why I love XDA.

HP Touchpad sleeping and will not turn on
Just a note to those HP tablet owners who experience the Black screen of death or sleep of death.
I am the proud owner of 4 HP tablets and two of them so far have had the black screen of death. I have read forum after forum trying to get answers to this problem. There was only one posting that has made cense to me. Someone posted that the tablets symptoms are very much like when the Phones use to go to sleep. The solution was to disconnect the battery for a few minutes then plug it back in. Then simply hit the hold the power button down to turn on the tablet.
The problem is taking the TP apart. There is a video on youtube on how to disassemble the tp. It is a little annoying that you have to go to such lengths to reset the hardware but HP will charge you 250 dollars to fix the problem. After you watch the video on how to open the TP, remove the 3 little screws holding the battery. Now slowly pry the battery up, they use double sided tape to hold it in place along with the screws. Wiggle the battery side to side and try to disconnect the battery connector. This can be done without removing the boards in the TP. Wait 1 min then try to replace the connector in the socket. It is on the underside of a board so when you have it in place use something to make sure it is tight. Plug the charger in to the USB cable. Without closing up the unit hold the tablet power button in until you get the battery charging symbol on the display. Let the unit charge while it is still disassembled. Just in case you have a problem. Once everything is operating disconnect to charger and replace the battery screws, now snap everything together.
This was the only way I was able to fix two of my four TP's. I am sure I will have to do this again because my kids always let the tablets go dead and they don't pay attention when placing them on the Stone for charging. If the tablet is not properly placed on the stone the tablet will not charge.
Hope this helps.
This by far is the best tablet for the money anywhere.

I realise this is an old thread, but I recently had a reoccurrence of the black screen of death issue and thought given the number of touchpads still out in the wild, I would share my experience on the off-chance it may help somebody.
My first experience of the black screen issue was a few months after having my touchpad (many years ago). The screen just went black and no combination of holding the reset keys for any period of time would restart the unit. I had suffered lock-ups before and found the reset combination to be successful, but this time none of that worked and I had effectively what appeared to be a dead unit.
Having contacted HP, I returned the unit under warranty and a unit was returned working. I say “a unit” as I was never quite sure if it was the same unit or a refurbed unit, but to be honest given the speed the units went out of stock during the fire sale, I was just glad to have a working unit again.
Well this week after several years of use including the installation of Android, the black screen occurred again. As before, no combination of the keys / holding for a period of time / pressing them a number of times etc had any effect. The unit was three quarters charged and I was using it up till the point the screen went black. :crying:
Given that the unit has no warranty and it was “dead” anyway, I decided to take it apart. Despite watching YouTube videos, this appeared to be more troublesome than I thought, but eventually I was in. Interestingly, the backlight on the screen was still lit, suggesting the unit was still powered. I did consider disconnecting the battery, having removed the screws as per the previous poster, but mine seemed to be well and truly stuck down and I felt I may damage it prying it away from the base.
However, looking around inside the unit, I spotted what was clearly a surface mounted switch that faced upwards towards the back of the screen. Out of interest, I pressed on this switch with my finger nail and my unit powered off (shown by the backlight turning off). I then pressed the normal power switch and the unit powered up as normal. I have attached a photo of the switch which resides close to the popout tab with serial numbers on that can be found on the right hand side of the unit.
It does appear strange that HP put this “reset” button inside the unit, facing inwards rather than outwards where a small hole in the back of the case could be used to press it. So if you do get to the opening the case stage, consider this as an alternative to prying the battery loose. Also if somebody can work out a way to make the button accessible from outside the case it might be a useful modification.

Oh I was so keen when I came across this post. A Reset Button! How great would that be?
Tried it, unfortunately it did not resurrect my dead as a doorstop TP. I was so hoping...
I just put a 'new' EBay battery in it a couple of days ago and tried trickle charging with a 1000mA charger for 24hrs. No joy there either.
All I get when I plug it into the PC is that it shows up as a "QDLoader 9008" (QHSUB_DLOAD driver) .
No flicker of life or light whats so ever...

Try to borrow a Touchstone conductive charger if you can. It's the only thing that has worked for me when it has totally drained down.
All the best.

That's what I was thinking - no joy there either... It is not even showing signs of getting the least bit warm.
I keep thinking and hoping that there is some way to resurrect this one but I may be wrong...
It's currently trickling on a 1000mA charger. Tomorrow I'm going to try the Touchstone behind it.
If that doesn't start something then I'm going to yank the new battery and along with the old battery charge them like an RC device.
(if I can ascertain the proper way to do that --- )

After several days on the trickle, still no life.
Took it apart at lunch and with the battery still connected to mobo it is showing 3.1V across the red/black. So I figure the battery
is good. Looks like the mobo is gone.
Not sure what else to try.

Hey helpful XDA'rs,
After somehow avoiding to have a tablet for this many years, I decided to get a 2ndhand Touchpad after seeing all the reviews, ROM support, price to relative specs, etc... so I bought a second hand 32GB tablet off of ebay. In fact, this one right here... http://www.ebay.com/itm/271192613408?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
Anyways, I got it earlier today, and plugged it into the wall charger it came with (the circular OEM HP one, with the long cable with a silver circle on each end). When I plugged it in, the little white alternating light under the home button switched on, so I figured it was working. Had it plugged in for about a half hour before I decided I couldn't contain my excitement and wanted to power it up. Of course nothing happened. Just a black screen and that little white alternating light mocking me.
I immediately hit up the google machine and XDA and realized that the screen was supposed to be on with an actual charging icon/animation or something like that. Up to this point, I still have not seen any sort of anything appear on screen. Just that little white light. Now yes, I've read through the posts.
First I checked to see if the HP charger/cable would charge my GS2. It did, and quickly (not some sissy trickle charge) and the circular HP thing felt warm to the touch. I also unscrewed the cylinder HP charger and blew in there with my breath pretty hard to clear out any possible dust, then screwed it back on tightly. I have used different cables with the HP charger, and used the HP cable with my GS2 charger. Same results, just that mocking little light, and the HP cylinder did not feel warm to the touch.
I have done pretty much all the button combinations I could find for at least a minute, with no results. Power + home, power + rapid firing the home button, power + volume up + home, power + both volume + home, etc. This is with the charger plugged into the wall.
I did notice two changes though.
#1 When I hold power + home, after maybe 12 seconds, the light stops alternating and is off - for about 2 seconds. Then the alternating starts back up. When the alternating light stops when I do this, it is always for the same amount of time, about 2 seconds, then it starts up again, regardless of if I continue holding the power + home, or if I immediately let go of the buttons, or immediately let go and then try pushing other buttons; it is always the same, the flashing stops after about 12 seconds, pauses with no lights at all for about 2 seconds, and then starts back up again.
#2 When I hold power + home + volume up, after about 12 seconds, the white alternating stops completely and never comes back if I don't do anything else. There are only 3 ways that I have found so far that will get the alternating white light back. First, just simply unplug and replug in, the light immediately comes back. 2nd and 3rd ways are to do the previous two button combos again, (power/home or power/volup/home for about 12 seconds).
MOVING FORWARD, here's where some interesting things happened, which hopefully is enough to have someone knowledgeable know what might be going on.
I decided to try #1 and #2 again, but this time, instead of the wall charger, I plugged the USB cable into one of my computer USB ports. My computer didn't make a device connect sound, nor show any kind of drive being connected in my computer. Just the same alternating white light.
Trying method #1 above, did the same thing. Power/home, alternating light would turn off for 2 seconds then start back up. Still no sounds from computer.
Trying method #2, finally something! When I held power/home/volup, after about 12 seconds the alternating light would turn off for good as expected, but then my computer made a noise! Not the device connected sound (low note to high note sound), not even the device disconnected sound (high note to low note), but that 3rd "device failed to connect" sound, the (three low tone sound). If you go to your windows sounds you'll know which sound I'm talking about. Anyways, I was glad to hear that the computer realized something was there. Although it was just a sound. Nothing in my computer, but for a second I did see a pop-up bubble in my lower right hand notifications say "device did not install correctly" or something like that. Now, with the touchpad still plugged into USB, and the alternating light off, if I either remove the cable (or hold power/home or power/home/volup for 12 seconds so the alternating light goes back on) then my computer makes that "device disconnected" sound. The hell is going on? I can duplicate those two sounds (the device failed to connect sound, and the device disconnected sound) over and over by holding power/home/volup for 12 seconds, and then unplugging and replugging the USB.
Having said all this, anyone have any ideas? Again, up until this point, I have yet to see anything appear on screen. Just that damn white alternating light.
I also know that this might also be a case of the really dead battery. It may just need to charge for like 48 hours via HP wall charger, or it may need to trickle charge for like 48 hours via USB to computer. If that's what it takes, but jesus I'm impatient and don't want to wait a week or longer, especially if I have a small window of opportunity to return this via ebay. So for tonight, I'm going to trickle charge via USB, but with the alternating light OFF via method #2, because at least with #2 and the light off, my computer makes a sound confirming something is plugged in. My rationale is that if it thinks something is plugged in, it will charge it.
Thoughts guys? A million thanks to anyone who actually read this entire essay and is still willing to help out!
Edit: the USB trickle charge I am attempting overnight tonight is via my GS2 cable, NOT the HP cable, since I've read all over the place that the HP cable is of poor quality.
Sometimes, when the battery has been completely depleted, it takes a real long while (24+ hours).
Your cable and charger seem to be Ok, so just plug it into the wall and check on it it tomorrow.
Post again if you keep having problems and we should be able to help you.
Good luck.
Not sure it will help but but holding power,home and volume down button is reboot ,I've had to hold it for 15 to 17 seconds before....

When i got my touchpad it was deeply discharged. I had to let it charge for several hours before it did anything at all. However i used the weak Samsung charger, so there was at least that message "please use the original charger" on the screen. So maybe you just need to wait...
Good luck though

To my joy, I woke up today with the screen on displaying a low battery charging icon. It's in the red though, but that's definitely progress. Is there a charging animation, or is it just a still icon? Mine has no animation and wanted to make sure mine didn't freeze.
I wanna say there is no animation just the icon (its been a long time since I've seen it ) but it only needs around 10% to boot... Now that you see the icon try holding the power and home button for 15sec and see if it boots.

I went and grabbed some food and upon returning I saw that my TP had completely turned itself on and was on some sort of setup screen, asking for me to select a language. I'm running through the setup now - two things. First, is it necessary to create a webOS account? Kinda like creating a google account for android? I intend on installing cyanogen10 on this, but wasn't sure if a weOS account was necessary. Or perhaps it's helpful. Second, the touch response is HORRIBLE right now doing the setup, takes multiple attempts to push an area, and with much more pressure than I would think is necessary. I'm assuming this is to low battery,. and it will improve as the battery returns to normal levels?
Not sure about the touch response issue but the low battery could be a possibility , as for the webos account i believe you only need to do that in order to use webos , i would do it anyways though .
Check here if you don't feel like making a webos acct: http://forums.webosnation.com/android-webos/318426-how-install-android-without-setting-up-webos.html

Yeah it was low battery. After a little more charging the touch response works fine now. Thanks! I was really stressing that I received a dead TP.
There are several programs available in the play store that will turn your tablet off when the battery % reaches a certain level. I use Automatelt (thanks to sstar for the tip) set at 20 %.

Is 20% the general consensus around XDA where it shouldn't go any lower than? Are some people setting it higher? Lower?
I have mine at 9% . some prefer more battery left to feel safer i suppose , basically you don't want to let your tp battery drain completely because it might possibly brick

I recently went on a 3 month trip. Before I left, my nook was working perfectly fine, when i got back, it didn't work at all. It's not dead because i left it plugged in overnight but it still didn't turn on. when i plug it in the LED goes from orange to green and then off (or green to orange, i can't remember). The screen doesn't turn on at all. I can't get to recovery either.
This is a Nook HD, I believe it had CM11.
:crying:
Can this be fixed
or should i plan it's funeral
Same here
The same has happened to me. Screen doesn't turn on, but there is power, I can play it into my laptop and something is there, just not enough.
Good excuse for a new tablet!
It can be fixed. I've done it before. It has to do with the fstrim not being compatible with certain hardware versions of our device. If I can remember how I fixed it, I'll post it here. Trying to fix mine (again).

If would be fab if you could fix. Seems to be a common issue
I was able to fix it. YMMV.
1) Make sure the Nook is completely off and unplugged
2) Take out your sdcard
3) Hold down power button until the "battery depleted" icon shows, then promptly plug in the power before the icon disappears.
4) Let it set. The screen will go black, then it will attempt to boot and get stuck on the faint black screen, but this time, the charging light should stay amber.
If you want to be safe, wait until the device reboots itself. That could take hours though. If you're plugged into the wall wait at least 30 - 45 minutes before holding the power button down til it shuts down and then rebooting it (with the sdcard inserted).
Good luck, I hope it works for you.
EDIT: Also, I've read this may also have to do with wifi sending the device into some sort of strange bootloop when the screen is off. I personally believe it has more to do with the fstrim of JB but perhaps changing the wifi sleep policy may prevent this issue from happening again. I'm skeptical, but figured I'd pass that info along if anyone wants to try it as well.

Not sure we have the same problem. My screen doesn't come on at all, I don't get a battery depleted icon, no matter how long I hold in the power button. The only sign of life I get is when it's plugged in, when it goes from orange to green after about 10 seconds.
Thanks for the help, but I think it's a lost cause.
YMMV. But mine was the same issue. You should be able to get the icon by holding the power button down for 5 or 6 seconds. I'd say just eff with it until that icon appears. Try different button combinations. I used power and home trying to get the icon to show.

Anyway... since people are continually running into this kind of issue...
Give or take 21 seconds after turning orange it turns green during actual boot cycle into rom
Give or take 10 seconds after turning orange is cwm internal recovery.
After about 10 seconds the charging screen image disappears.
The charging screen image once finally no longer may not show up again until full power off/on (holding power button > 10 seconds or full battery discharge). Unplugging and plugging back in does nothing except making the device look bricked if there's too much light shining on it.
Device may not automatically leave the above state under a specific situation(s). May still need manual full power off/on.
Guessing 10 seconds could also be something else during the early/late boot process or other. The light changing color though should indicate that something is indeed happening.
Light should stay green during the boot process if its completely and fully no questions asked 100%. If you go based on that than yours doesn't appear to be completely fully charged which should either mean its turning on and using battery or not charging correctly.
The light turning off is curious. The device could be shutting off. If light comes back on a moment later then the device has rebooted. if the light stays off = n/a.
If its booting into recovery then the device would be available via adb. At that point it could be further evaluated.
On the off chance the screen was damaged it should boot and usb should be available via computer as well as adb.
If not then its probably toast unless its simply not getting a good enough current causing mislead battery stats and/or not enough energy to get to charging screen (bad wall power adapter in use, damaged power cable - though could be bad battery, defect, damage or whatever). OR there's some major error on behalf of the user happening (think should have tried that in the morning not while 1/2 asleep or came home from long trip and forget how that works).
Maybe the only other things are the emmc brick bug, was left sitting in the sun or heat or ocean air or other physical damage/defect even to the power port as well.
Or maybe it was mad that you left it. Shouldn't have hurt its feelings you know. At least its not crying battery acid on you.
That should just about cover everything except for the things not mentioned. Since its your device, you decide what happened.
Its complicated so anyone see any improvements, clarifications, or mistakes? Please put it in a post.

Bumping this thread to make it aware that there is a real answer. I have been able to duplicate this problem and rather easily too.
The problem is indeed from bad power. The device isn't receiving the correct amount of power needed to charge and start from a fully discharged battery.
To safely* duplicate this you can use a usb extension that isn't fully connected to the nook power cable. You may need to fully connect it first then slowly disconnect/connect till the light turns green when it should actually be charging. It won't actually charge in this state, or if it is, its very little and the battery percentage will continue to drop.
Leave the cable as is and unplugged. After the tablet is fully discharged, connect the usb cable. The light will change through the modes and turn off. The device will not turn on.
There are probably other ways to cause the problem like for instance a portable usb battery that doesn't put out enough juice (not the orange kind). Etc.
* It didn't hurt mine, but not my fault if it breaks your device.

I actually ended up fixing it yesterday!! I haven't touched it in about 3 months, and I was planning on just throwing it out getting rid of it some how. For the heck of it, I decided to plug it in, assuming that it was gonna go through the same process. But this time it went from green to amber, but it never went off. So I pressed the power button and the battery icon appeared. This was a really good sign. So I left plugged in for about 5 to 10 minutes then tried to power on.:fingers-crossed: As soon as I saw that '' Nook" boot up screen, my heart stopped. It booted up perfectly and I almost blew up from excitement :victory:. So I then flashed the stock firmware back onto it, so this would never happen again.
I guess the battery had to be completely depleted or just had to cool down. Idk but either way this was one heck of a miracle
So I recommend for anyone having this problem to just leave it off and don't mess with it. I wouldn't say for 3 months like I did but maybe test it each week or wait a month if you have good patience
Wow. Man, that's awesome! Glad you posted that update on it. Thought if you had posted an update it would be the opposite as in trashed it
Actually, I guess only you could answer if you had also moved/unplugged the power cable from the wall adapter or put it into a different wall adapter, etc. Thinking there could have been a difference there.
These modern day devices are so finicky, guess anything is possible. Like you say, maybe sitting without power is another answer.
From some experimentation I have etermined that your power adapter (that plugs into the outlet) is the issue. It does not like to be leaft plugged in indefinately. It will continually use power even when the nook is not plugged in.
Also, if you use a differnt adapter you will have the same problem unless it is also of the exact same voltage and amps.
When I put my nexus to charge, screen flickers like it needs more power. But when I increase the brightness it goes away or I can't see it. Tried a different power outlet as well. And I'm using the turbo charger.
Anyone experiencing this?

Yes I am also experiencing this issue. I contacted the (UK) Google Play support and they suggested:
Reboot to Safe Mode (Test Charging)
Factory Reset Device (Test Charging)
In both instances Google Play were trying to eliminate any applications that may be causing the issue. Needless to say I tried both suggestions and the issue still prevails. I have requested a replacement device but you are quite right...this only occurs when you use the Turbo charger - I tested a HTC M8 charger and the issue disappeared. It is also not consistently replicated - sometimes it happens, sometimes it doesn't. It seems to occur between 30%-80% of charge and then stops (I could be imagining that!).
I am hoping its nothing serious and either a faulty charger, a feature/symptom of "turbo" charging or at best just a one off faulty device. I may even ring Motorola themselves and see if they can explain whether it is a fault or a non intentional side effect. The latter would be very disappointing.
Have you made any progress?
Mine does the same thing. I'll try with a different charger and stuff later, but just thought I'd let you inow that the two of you arent alone.
It doesnt bug me. Normally when my phones charging I'm not using it.
Same here. Was gonna post but wanted to wait and see if someone else would first. Kinda annoying but not a big deal. It doesn't do it with my car charger and maps open and that's usually the only time I charge while using the screen.
I contacted Motorola and they suggested to wipe the cache too. I haven't successfully been able to do that yet. I think also the representative may have mistaken my explanation as definitely being caused by an application. I doubt it will rectify it but nevertheless here is the response below, it may help. Either way both Google Play (UK) and Motorola seem unaware/surprised regarding this issue, yet still very interested in helping fix it.
Thank you for contacting Motorola.
I am sorry to hear that there is a problem with you phone.
Please try the steps below to see if they can solve the problem.
If the first step does not solve the problem please continue with the next.
1. Safe mode
To Enable Safe Mode, please try the following:
1. Press the Power key
2. Touch and hold Power off
3. Touch OK when Reboot to safe mode appears
4. Phone will reboot and Safe Mode will appear in bottom left corner
5. Check if the problem is solved. If this is the case continue with the next steps. If not continue with the Clear Cache option
6. While in Safe Mode, launch apps one at a time to identify the app causing the problem
7. Remove the app that causes the problem from the device
To remove an application:
1. From the home scree, tap the circle with 6 dots (Menu)
2. Tap and hold the application that you want to remove
3. Drag tp Uninstall at the top of the screen
4. Confirm by touching OK
After you have identified and removed the application simply power cycle the device to disable safe mode.
2. Clear Cache
CLEAR CACHE PARTITION
1. With the phone powered off, press the VOL DOWN KEY for 2-3 seconds then POWER key then release.
2. The device will display different BOOT OPTIONS
3. Use the VOL DOWN Key to SCROLL to Recovery and VOL UP Key to select
Tip: If the device reboots, you may have waited to long to make a selection, you will need to begin the process again.
4. The device will display the Motorola logo and then the Android in distress ( logo with Exclamation mark)
5. Press and hold the VOL UP key for 10-15 seconds. While still holding the VOL UP key tap and release the POWER key
Tip: You can try this step, holding the phone in landscape. If you are stuck on step 6, try a force reboot by pressing the Power key and Vol Down key, and start the process again.
6. The device will display additional menu options (Text will appear in BLUE)
7. Use the VOL DOWN Key to scroll to wipe cache partition and the POWER Key to select this option
8. The device will then perform the partition wipe
9. The device will reboot and start the normal power up sequence
If the problem is still not solved please backup the information on the device and continue with a factory data reset.
Once you have backed up your information, please try the following to perform the factory data reset:
1. From the home screen, tap Menu icon (a circle with 6 dots on it, located at the bottom).
2. Tap Settings.
3. Under the Personal section, tap Backup & reset.
4. Tap Factory data reset.
5. Tap Reset phone.
6. Tap Erase everything.
Please allow several minutes for the factory data reset and reboot processes to complete.
To setup the device after the reset has completed, refer to Initial Activation and Setup.
This should solve the issues you have encountered.

Happens to me too. Don't see it as an issue unless the flicker occurs when the phone is disconnected from the turbo charger
Happens to me as well. Also, when I wake up in the morning, I can "hear" my phone charging. Something makes a constant noise, and it goes away as soon as I take the charger off.
Only hear it when the phone is fully charged and still on charger.
Thank you for the reply guys. Since I'm on my holidays I didn't have that much time to deal with this issue. I was going to send back the phone when I get back but now i'm thinking to buy a wireless charger or use another charger since phone get extra hot too when you are using the turbo charger.

you shouldn't use the turbo charger over night. get a normal one or get a Qi charger.

Says who?
Hi
Just a quick update.
I received my replacement device and I haven't seen the flickering yet - hopefully that is the end of it for me.
As somebody else has said, if it doesn't bother you then save the hassle. If it does, Google Play seem happy to replace under warranty.
Thanks for the comments.
Sent from my Nexus 6 using XDA Free mobile app
I experienced similar things with the screen flickering but this was off the charger as in not using the charger. I notice it most when you have the screen brightness low up to about 25% with the adaptive lighting turned on. The moment I turn off the adaptive lighting and raise the brightness above 40% the flickering seems to go away. So my screen flickering issue has been when I'm not using the charger. Has anyone else experienced this or might this be a defective screen?
My screen flickers at low brightness only. Its not that bad and I figure it night have to do with how dim the screen gets in the dark but I'm not sure. I may eventually RMA it, however it doesn't bother me currently so in fine with it happening.

Thank you. I've been using a regular charger at night for 2 days now, no noise in the morning anymore. I just use the turbo charger for a quick charge if I need one during the day.

Why? The quick charger only draws what the power control chip determines it needs. It won't overdraw current. I've used my quick charger over night many times with 0 issues. I've also used my quick charger 2.0 car charger on a road trip the whole way and again no issues. My battery life is still the same 6-6.5 hours SOT that it was when i bought it. I now use my qi charger. Where is the evidence that says its bad? If there isn't any then its not good to spread rumors about it being bad. (I'm not saying your losing, I just want to see where/how your concluded that)

When you leave your phone on the turbo charger overnight, do you hear a noise in the morning coming from the N6? I could hear a noise coming from the charging port in the morning on the turbo charger, its fine now with a regular charger.

Nope, mine doesn't buzz at all when I leave it. Ill test it again later, but I haven't had this issue. I have 2 of the quick chargers for my home and one for my car and my wife uses it for her S5 without any issues too. Maybe your charger is the issue?
Quick charge only charges quick for about 20 Mins then turns to the normal 5v 1a setting that most chargers use. I read the specs somewhere and it is completely determined by the phone. So it's not gonna hurt using it all the time. However if yours is buzzing it may be the charger like the others said.
You could download battery monitor widget and watch the voltage and amps that its drawing. At peak it draws 2.5amps at 9v if I recall correctly. I'll check it when my battery gets low again. The quick charger doesn't have any adverse effect that you would notice over a standard 2 year usage for a phone any more than a standard charger. Unless your battery is really hot all of the time it won't degrade any faster.
I am getting this flickering when charging with turbo charger too.. Hmm I wonder if this will kill the screen
Hi
I’m wondering if anybody has any advice regarding my problem. I have looked here and tried what has been suggested.
My stock, never rooted, never flashed, Xperia T (think it was Android 4.3 but can’t now check, the latest Sony rolled out) was working fine until yesterday. I was on a plane and noticed it had 20% battery life left so I plugged it into the onboard USB port. The problem is I think I hay have plugged the cable into the port the work way round – not the connection on the phone, but the actual USB socket. This should be impossible but somebody obviously had broken the port and it turned out the cable could be plugged in both ways! (I don’t know if it was plugged in the wrong way round but is the only thing that could possible explain the sudden death.)
Could this have bricked it? I suddenly couldn’t get a red light to show charging and holding down power on and volume up or down does nothing. I tried charging overnight via a wall socket when I got home but the result is still the same. Just a black screen and no sign of life. I have also tried plugging it into a computer with Sony’s PC Companion but as the phone is not ‘on’, it can’t be found.
Does anybody have any advice where to go from here? I’m more concerned about some recent data from holiday on the phone than the actual handset itself. If the phone is dead, is there any way to read the internal memory?
Thanks
Try this: Unplug the charger, press the power button. The phone won’t power up because there is no charge left in the battery. But press the power button along and while doing so, connect the charger without releasing the button. Now, you will probably see the red light. Please don’t take off your finger from the power button for around 1 to 2 minutes when the red light for charging will glow continuously. If you feel tired holding it, you can try sticking a tape on it in it’s pressed mode. Once you are sure that the phone is now charging the battery again(red light keeps glowing even after the power button is released) kindly wait for 5 to 10 minutes or may be more before you press the power button again to power the phone up. Now the phone will be up and running
If that doesnt work maybe ur battery is dead or usb port broken
Thanks for the advice. I gave that a go after trying a 24h wall charge and not touching it (which did nothing).
So, I held the power down, plugged it in but nothing. I held it down for around 5 minutes both manually and then repeated the process using the rubber band trick to keep the button held down but no red light ever came on. I think I’m going to try a new battery as I genuinely see that I have nothing to lose as I doubt it will be possible for anybody to recovery data given as the phone can’t be switched on so if I break it further I’m in no worse position!
Thanks again for trying to help though!:good:
When I got my xperia t it was in described condition. I also tried everything (rubberband trick and so on) but the only thing working was to open it and pull and put in again the plug of the battery. After that it booted immediately and I got this sleep-of-death-thing nearly every day... Since I soldered the battery as described in this Topic it happens only ~once a week. Good luck!
SOLVED! In preparation for the new battery arriving, I decided to take the back cover off. I unhooked the top battery connector and decided to connect it back up again, just to see if it did anything. Plugged in the charger and a red light came on straight away! I let it charge for a good couple of hours and switched it on – not as easy without the case attached – and it worked. I’m so frustrated with it being such a simple issue as needing to disconnect the battery but even more frustrated with the design that it is meant to be a ‘sealed’ unit with a non-removable battery. I used to often need to disconnect my old Omnia II battery to restart it but that was a simple case of cover off, remove battery, replace battery , put cover back on, not the creaky, back cover fear of cracking exercise of yesterday. Still it’s working now and hopefully life in the old phone yet!
