[Q] HP Touchpad with a 12W Charger(iPad 3) - TouchPad Q&A, Help & Troubleshooting

I don't know if people even use their touchpads anymore lol. So I found my touchpad collecting dust and decided to bring it back to life. I plugged it in with my beats 2.0 usb cable and ipad charger and the home led light just blinks side to side. I don't know what to do at this point as it won't boot and doesn't respond to any button combo. (yeah i know tps must not get drained -___-)
P.S.: I don't have webOS and if I remember correctly I'm at CM11 4.4.4

I also don't have stock usb cable and wall adapter. Both already broken.

[Q] Charging Woes

I tried posting a day or two ago about this, but wasn't able to get any replies or any help at all actually : /
Anyways, for some reason ever since I rooted my nook, when i plug a charging cable into it, it either
(a) Pulls out of sleep mode and shows the Lock Screen, which drains the batt
or
(b) Will actually turn the device ON and do the above stuff, making it really hard to charge in general
Is there any way to fix this? Right now my nook keeps hovering below the charging line and reboot looping, then when it does have enough power to actually full boot, it drains itself faster than it can charge bc it runs the screen at full brightness.
HELP PLZ!?
Your charger must be bad or some other such problem, because that's what the Nook does: plug it into the charger and it boots itself up or comes out of sleep to the lock screen. It will blank the screen relatively soon after if it is running correctly.
On top of that, the charger supplies way more than enough juice to charge even under heavy use.
Are you using the nook charger and the nook cable?
Im using a MicroSD cable either through the computer or through an actual AC port in an adapter.
Im basically now at the point where I can't charge the thing enough to get it past the "Battery is Dead, wait 15 mins" mark. It sucks so hard :<
Im thinking I may have to take it back to Best Buy and try again, I have the warranty on it, just I really dont want to do that! >_>;
I am having the same problem......

Are you using the official B&N USB cable and charger that came with it or just generic ones?
Using a standard MicroSD Blackberry adapter.
I tried going to bestBuys (i work for them) and getting a black NC cable, no one sells any!
My next stop is going to be BN themself. Is it really that big of a difference what cable you use?

Yes, it does make a difference. A standard USB cable and charger takes 8 hours or so to charge an NC. The B&N cable and charger that came with your NC can do it in 2. Use them.
yes, it seems to make a difference. I can only connect to the PC [mounting the drive] with the originally cable. With the generic cable, it will charge but doesn't seem to charge as fast [less than half the speed]. I would suggest you try to get your hand on a original and see if there is a difference for you also.
from the user manual:
CAUTION: Only use the Barnes & Noble power adapter and custom microUSB cable supplied with your NOOKcolor. Other power adapters might damage your NOOKcolor and its battery. Do not use a power adapter and cable intended for other models of NOOK eReader. Use only a NOOKcolor power adapter and cable.
NOTE: Using your NOOKcolor’s microUSB cable, you can connect your NOOKcolor to your personal computer to transfer files. Connecting over USB cable does not charge your NOOKcolor, however. To charge your NOOKcolor, you must plug it into a wall outlet

CSquid cable

There is a very nice cable out there called a CSquid. They make one for the Streak.
I took an external battery pack which has 2 USB charging ports and plugs straight into the wall on my trip to Vegas. It worked nicely when I tested it at the house prior to the trip. I used it with my Streak on the plane while the wife and I watched a movie. It came in damn handy charging both the wifes phone and mine at the sametime while drinkin way to much playin video poker at the bar.
Then I let the battery on my tablet die. I mean completely discharged dead. So I just plugged it in to the battery backup, plugged the backup into the wall outlet and NOTHING. No charge indicator, no lights on the softkeys, nothing. Tested the USB port with my phone, all was good.
So I ended up buying a USB wall/Vehicle charger at the gift shop of Harrah's for twice what it was worth. Plugged in and the Streak started charging, same stock cable I used with the battery backup charger. After that I was able to use my Streak with the battery backup on the plane ride back home with no problems.
Which lead me to the CSquid cable. It's designed to function off of low powered USB ports. Some device out there, ours included, the Galaxy Tab and the iPads as well, will not charge from a depleted battery state off of some USB ports. This includes PC's if they enter into a low power state. Some ports on laptops for example, my HP has 2 ports that are fully powerd and 2 that are not. A keyboard or a mouse works fine, but try a 3G modem and it detects it, but won't function. Flip the same modem to a port on the other side and it works like magic. What I'm saying is this problem is device specific.
So I recreated the scenario and tested same.
I ran a movie on my Streak until it shut itself off. I tried powering up and it wouldn't go. I plugged my battery backup into the wall, grabbed the stock Streak cable and cabled them up. No charge indicator on the Streak. The battery was dead, dead. Reconnected it twice and the same result.
I then repeated the process with the CSquid cable. I immediately recieved a charge light. This was a good sign. I tried to power it up and it wouldn't go. So I went out to the garage and had a smoke. Came back in about 10 mins later, hit the power button and the Streak booted up. All was right with the world.
If you're in the market for another cable you want this one.
I ordered the cable off Amazon for $20 and some change for delivery. It showed up USPS in 3 days.
This is their site: agreenc.com
Oddly they don't list the Streak on their site, at least yet. But this cable does exist for the Streak.
Like I said I got mine off Amazon. Just search them for Dell Streak CSquid and it'll pop right up
Dear elodahl,
I'm not sure whether I understood you totally correct but you seem to have the problem when you try to charge your streak from you battery backup when this last one is plugged into the wall, am I correct? Was the battery backup discharged and hence you plugged it into the wall? If so, it could be possible that the energy taken from the wall is completely dedicated to charge the battery of your backup device and it is not drained outside to charge the streak. This could explain why after the cigarette the streak started to charge: the internal battery of the backup thing was charged enough to start draining energy to the streak.
Could be this correct?
On the other hand, do you know if this cable has the "on the go" pin enabled? I mean, using a female-female usb adaptor, have you ever tried to plug an external usb device or keyboard to the streak through it? At the moment and to my knowledge, non of the existing cables for the streak can do something like that, one has to open the cable and soldier together a couple of pins to make this possible.
Many thanks
I haven't tried using the cable with a gender bender and use it as a pass though. I don't have a need so I never screwed with it.
This isn't a problem to be solved. This is a solution to a problem that exists.
The battery backup was fully charged. The Streak was fully discharged, which is a big part of it. If you end up with the Streak fully discharged you can't get it to power up off of say a battery backup or (some/most) PC USB ports. You won't even get the red LED charging indicator to light. Again this is with a fully discharged battery on the Streak.
Basiclly what the cable does when you flip the switch on it from it's standard data cable position over to the power postion is send voltage down an additional pin. Voltage on this pin makes your USB power source appear as a AC power source. This allows the system to boot, and charge, even with the same exact USB power source that did not work prior to you sliding the switch on the cable.
This is similar to what Motorola did a few years ago with their USB charges. I carried Motorola Q for a couple years which is were I ran into the issue. Yes The device had a mini-USB connection. Yes it could charge off of that connection. But it could only charge if you used Motorola's mini-USB charger. Only a select few 3rd party mini-usb chargers would work, most wouldn't. On the other hand if you could charge a Motorola off of a charger that charger would charge any other mini-usb device known to man.
I found the pinouts for Motorola's charges on some site which showed that they were using the "spare" pin. There is a open pin in the USB spec. which an OEM can use to do whatever they like.
You can charge a Streak off of any USB power source unless you completely discharge it. If you completely discharge it you need an AC power source, or something that looks like an AC power source to the Streak. Which is were this cable comes in.

Touchpad is charging but not oooting, webos doctor not working

Hello everyone,
I installed a JB rom a few weeks ago on my TP (can't remember which one)...it worked for a little while, then i wanted to flash something additional and it seems to be bricked ever since and has been laying around...which is why I can't remember what exactly I wanted to flash
Anywho, if i connect it to the PC the notification LED on the home button is blinking..but that's it. no combination of power/voldownup/home button seems to be working and when I try to run webos doctor it doesn't recognise my device.
can anyone please help me?
When you say bricked. Do you mean stuck in a boot loop wouldn't turn on etc.
Have you had it connected to the stock charger or better still on a touchstone and if so for how long.
The more information you can give the better.
No it doesn't turn on at all, screen stays black.
It's been connected to what i think is the stock cable to my pc (there are too many Micro-USB cables laying around here ) for about an hour now and i just put it on the touchstone (LEDs are still flashing)..
Leave on the Touchstone for at least a few hours preferably overnight then hold the power and volume up buttons for at least 30 seconds if nothing happens do the same with power and home buttons and post any progress or lack of, but the first thing is to try and put some charge into it and the best for that imo is the Touchstone.

The stock cable for the touchpad has a silver dot at each end. I have two touchpads ad the connection is very loose and unreliable. It often won't charge. I bought new Micro USB charge/sync cables and charging is no longer an issue.
The USB port on your computer is not powerful enough for anything it trickle charge. You need a stock touchpad charger.
Well i charged on the touchstone and then after a few hours i was able to boot into recovery and flash a new rom problem solved, thanks anyway!

Dead battery, BSOD revival - What worked for me MULTIPLE TIMES!

Hello Everyone, sorry for the long post but I do want to share my journey on how I got my touchpad brought out of the BSOD more then once and what, so far, is a method that works for me.
I've had the touchpad for a few years now and ran CM 7, then 9 and now Jcsullin's CM11 on it.
Just like a lot of us here I have ran into the issue where the battery on the HP Touchpad completely drains and we are stuck with an unresponsive unit. I usually try to charge it every time I see the battery % starts to go below 20-30% but sometimes I do miss it or fall asleep while watching a movie and BAM - dead touchpad!
So over the years I've tried every tick in the book and suggestions all over the web and different forums - various button holding combinations, changing wall chargers, using low-mA or high-mA chargers, connecting to PC usb port in order to trickle charge, reflashing A6 firmware - and sometimes one or the other options has been working and has successfully brought the touchpad back to life right up until sometimes in October of 2014. Touchpad died and no matter what I tried I could not bring it back to life. Spent days on various chargers and constantly trying to hard-boot it (power+home buttons hold) and nothing. I got to the point where I was going to open it and use my RC Car LiPo battery charger to directly charge the battery. So I got everything ready and for one last time connected the touchpad to my PC's USB port - but this time something different happened!
When you connect touchpad to the usb port on the computer you hear the double ding sound - computer acknowledged that a device is connected to usb, and then, when the touchpad is dead you would usually hear a triple ding when the driver cannot initialize. It happened as it is supposed to so I hold the power and home buttons at the same time and give it another go. I hear the double and triple dings again, keep holding the buttons, hear both again, keep holding the buttons, and then all of the sudden I only hear the double ding but not the triple!!! So I thought that maybe I just missed it and didn't hear it - let go of both buttons then hold both of them again and 13 seconds later - double ding and that's it! No triple ding and my windows device manager is NOT showing unloadable device anymore! So I decided to leave the touchpad connected and see what happens. I walked away from the PC and about 5 to 10 minutes later I come back and see the home button has a light flashing left to right... at that time my heart probably skipped a beat! I ran to get the original usb wall charger that came with the touchpad, quickly took the usb out of the PC and plugged it into the wall charger. The light on the home button started flashing again, about 5 minutes later an icon with a battery and lightning came up and 15 minutes later touchpad booted right back up and I could see that it was finally charging again!!!!
About a month goes by and I accidentally let it die again! So I go through the whole routine of button presses and so on and so forth... spend 2 days trying to revive it with no luck until I suddenly remember what happened last time. I go back to the PC, plug it in, do the Power+Home buttons holding but this time it didn't work. I just kept hearing double and then triple dings... After about 2, 3 minutes I got tired and decided to plug into a different USB port (for sh*ts and giggles ). Held the buttons and voila - it worked! Just like a few months back I hear the double ding and no triple and I was able to revive the touchpad. I decided to do a little investigation and noticed that my PC has 4 USB ports in the front, however, 2 of them are USB 2.0 and 2 are USB 3.0. I had touchpad connected to USB 2.0 when nothing was happening but this time when it came back up it was connected to USB 3.0!!! My USB 3.0 ports have letters 'SS' in front of the USB symbol right above the ports.
This past weekend once again, due to my own stupidity, Touchpad dies on me. This time I try the usual Power+Home button holds while connected to the wall charger. After about 2 minutes I see that the Touchpad is not coming back up so I go right to my PC and right into USB 3.0 port. Hold the Power+Home button and BAM - no tripple ding! 5 minutes later the light of the home button starts flashing, I plug the USB from PC to the wall charger and 15 minutes later Touchpad is back up and running!
So to summarize - it looks like USB 3.0 for some reason is able to force the battery to start taking charge! I know that USB 2.0 gives out up to 500mA (0.5A) power and USB 3.0 gives up to 900mA (0.9A) of power. It is still much lower then the original wall charger but 3 times now it has done the trick for me!
This doesn't mean that you guys have to go and let your touchpads die just to test this procedure but if you are stuck with an unresponsive device - give this a try! Hope my story helps some of you in reviving your good old Touchpad!
P.S. I don't use the original micro USB cable that came with the touchpad (due to an accident it got destroyed), just the original wall charger.

Tablet won't charge when on (android and Windows)

Hi everyone! Today a very strange thing happened... I was using my tablet with Windows, with a usb hub attached to use a simple mouse. This hub has a micro usb output, so that I can charge the tablet while plugging in usb devices (that's exactly the one techtablets uses in one of his videos about this tablet). All of a sudden it stopped charging, so I tried rebooting: NOTHING. Then I switched to Android, but still no luck!
I'm happy I see that it charges if it's completely off, but I don't think it's normal!
What do you suggest me? This tablet is fundamental for me, as I study with it!
Anyone who could kindly help?
Same here and notice this after your post here. Windows notice that i plug in the charger (screen brightness was different with pluged in charger) but doenst charge.
I'm thinking that it might be BIOS related... Unfortunately I can't update it (I have 2.02 version already), or at least sort of reflashing it, cause I don't have a usb keyboard... Can you make a try? Cause it's weird it happens on both Windows and Android! I also noticed that if I have it off, charging, right when I trigger the power button and the teclast logo appears, right before the choice of the OS, it stops charging..
i have same problem, do you resolve it for present? how do you use your tablet?
Mine was a bit temperamental and as described above for the 1st 6 months but now it will not charge even when off unless it is left for days. Then no where near full charge.
I had very similar problem on my old teclast c6j6 tablet a year ago .
It seems my usb connector in tablet was too loose after few months .
I opened and pressed ( squeezed ) usb connector and was work again fine .
For the time being I connect and disconnect usb cable very gentle on all my teclast tablet and is fine .
I have the same problem. The tablet will not charge while powered on and starts charging right away as soon as it powers off. I do not have to wiggle the cable or anything. ON = not charging, OFF = charging. It's very unlikely that this is caused by a bad connector.
Be careful when you use Android. If Android shuts down because the battery is low, the tablet will start as soon as you connect a power cable. The tablet starts up, stops charging because of this, shuts down because the battery is low, starts charging as soon as the tablet is powered down, starts up, stops charging, shuts down, starts charging, starts up, stops charging and s on. Viola: you have a boot loop.
I wrote about it here: http://forum.xda-developers.com/x98-air/help/dead-battery-bootloop-t3243993
There is a fix which requires some soldering. This is a YouTube video which describes the procedure:
