Here's an interesting discovery - would be interested to know if anyone else has the same issue.
Basically, my old WM6.5 phone (Touch Pro) used to take charge from a powered USB socket, even when the computer was turned off.
Plugging the HD7 into the same USB socket, and the phone won't charge. That's fine, I can understand there may be valid reasons for it.
What's *really* interesting is that if I leave the phone plugged into this powered down PC overnight, the battery is pretty much dead in the morning. Compare this to leaving the phone unplugged completely, and I'd generally see 15% battery usage overnight.
The solution is pretty simple - don't leave the phone plugged into this USB socket, but it seems odd.
Any chance someone else can try this?
Is the Zune client on your pc open because my phone will not charge with zune open
but once i exit out of zune on the pc it charges fine...
ive lost my charger and too lazy and cheap to buy a new one so im just using the pc to do it....
no - the PC is actually powered down. However, with soft power switches, the USB port stilll can get power, as proven by my ability to charge my Touch Pro from USB when the PC's off.
I'm not sure what could be causing this, but i will try to see if mine is the same too, then i will post feedback
I've charged mine on a USB port at work, but there isn't any Zune software in the way there... Honestly, I don't sync through USB, so I never noticed this, but at work I have used the USB port on our camera system to charge my phone...
most likely cause is the fact that the computer reduces the amount of current send to the usb port when powered down.
normaly all that is needed is a move of the mouse or a key press to power the computer back on.
now both the keyboard and mouse are low power devices.
now my guess is that the touch pro needs less power in standby then the hd7, and therefore the first will charge and the second will drain.
so to solve this question you need to measure the power comming from the computer in standby (powered on it's 500mA), and both the phones in standby mode.

Here's what I find odd:
The phone will not charge unless powered on. For example, if I have the phone turned off, and plug it into the wall charger it came with, the phone boots up. It will NOT charge while turned off.
Anyone else notice this?

i saw someone mention that the led won't turn on during charging while the phone is turned off.
sadly he didn't wait long enough to see if the led turns on when the battery is fully charged.
also i have no idea which model he was using.

I posted earlier about charging issues on the HD7: http://forum.xda-developers.com/showthread.php?t=849548
What I found was that if you have the HD7 plugged into the USB port and then you suspend/shut down the PC, it'll stop charging (while all other phones I've used - iPhones, HD2, etc. - will keep charging).
Once you suspend/shut down, you need to then unplug and replug the HD7, and it should start charging again. Not sure why this happens, but I need to do it every night, otherwise I have a dead phone in the morning.

That is apparently a "feature" of WP7-- the phone will automatically turn on when plugged in.
Okay, so here is the story, I am without the OEM Nook charger (cable) and it seems that no other charger will charge it, I splurged on the Nook in the first place therefore not having the funds to buy another cable. So what I am asking, is, does anyone else know anyway to charge it?
I got a generic retractable microUSB cable. Charges fine from a computer (albeit more slowly than with the Nook charger). Interestingly, it charges super-fast when plugged into a powered USB hub.

You can charge from a computer? How? I have battery stats pulled up and I watch it as I plug it in, It mounts, but no charging

It is indeed charging when you have it connected to the computer although the amperage isn't great enough to trigger the Nook into a charging state. Keep it there for an hour or so and you'll notice a difference in the battery level.
I would turn off the auto mount of storage when charging from a computer. I charge my nook using USB every day at the office.

No it doesn't, that's a bug. At least if it's what I've seen.... My NC will sometimes to from say 70% to 100% nearly instantly when plugged into the computer. But it doesn't happen every time.. I haven't tried to figure out what makes it happen, but could be related to repeated plugs of the NC to the computer or something, as I was farking around with disabling/enablng automount when I last noticed it happen.
Later it'll start dropping like crazy and recover the "incorrect" charge status back to normal, like 5% drop in seconds several times in an hour is what I have seen it do in the past.
Okay, so if I leave it plugged into the computer, with auto mounting off, it will charge?

Mine does, I started the day @ 75% a few hours later it was fully charged.
I had same problem, bought nc used and got wrong cable
Used nook wall chager with wrong cable and got " not charging" but i left it overnight, next day it still showed same amount of battery it had night before so i thought it didny charge.
Went to buy nc charher $25!!! Ouch. Plugged it in and battery percentage went from 10% to 99% in 1 second
My theory is that a regular usb does charge it but the nook wont recognize it, but the battery is charged

Well, what you describe is not what I've seen.. What I have seen is that it will charge from ANY source, although it does NOT show it on the status bar or in the Settings, but if you watch the charge percentage (I use Battery Snap) you'll see it charging, assuming there isn't much of a load on the NC. As far as I know, it charges at 500mAh unless it has the NC Cable + Charger plugged in.
What I've also seen is that sometimes the charge jumps to 100% for seemingly no reason when plugged into my PC. Doesn't happen all of the time, but it's not charging fast, and it's not a "recognition" thing, it's completely false. If it jumps from 70% to 100%, it's still only 70% charged. It'll "discharge" really fast later, presumably as the system does whatever it does to determine battery charge (battery voltage etc).
I cannot get my sisters TP to boot. I guess she let it die completely, so now when I plug it in, all I get is the home button to blink back and forth. If I try to turn it on, I get the red battery with a lighting bolt icon, then a white plug icon, and when I plug it in from there I get the "To reliably charge" message. I don't have the original ac adapter or cable because she lost it. I have already reflashed the A6 firmware. Also, if I leave it plugged it with the home button flashing, after about 20 minutes or so, the flashing stops for a few seconds, then starts for a few seconds, then stops again and so on and so forth. Is there anything else I should try? Or is this thing dead?
See if you can get an OEM cable or a Touchstone.

Leave it charging for a long time, 24 hrs +, it should charge.
Good luck.
original charger

You need to find an original charger or maybe a compare able 2amp Carter will work. A standard phone charger or USB port on your computer is not powerful enough to charge it.
Check amazon it shouldn't cost more than $10
I have another tablet charging block that is 5.0v and 2 amps, but when I use that all it does is make the home button flash then stop then flash again. I left it charge on my computer overnight to try and get it to trickle charge. When I woke up the home button wasn't flashing and when I try to turn it on, the red battery comes up for a second then the white plug icon. I guess I'll see about getting an OEM cable, hopefully that works.
UPDATE: I got it into "recovery" mode? It was plugged into my PC so I held power and vol up until my pc recognized it. But it's showing up as palm in the device manager, and no drivers seem to work for it.
UPDATE 2: My sister found her OEM charger and now it seems to be actually charging. Thanks for the help, I'll let you know if this doesn't work.
Yep, usually issues like that are because of not using the OEM Charger.

Battery dead, bricking issue
I have had several charging issues with my Touchpad. I am using ClassicNerd Butta OS. IF I am using the Android OS (Butta) and I turn off the Touchpad and then plug it in to charge it will restart the Butta OS. When this happens the Touchpad discharges instead of charging. So, when I come back later the Touchpad is dead and it takes a lot of messing around to get it going again. To prevent this I always turn off the Touchpad when I am using the Butta OS but I don't immediately attach the charging cable. Instead, I wait a bit. Then when I plug in the charging cable I immediately switch to the WebOS operating system. The device seems to charge well using WebOS. When it is done charging I unplug the cable and turn the device off. Next time I restart the Touchpad I let it boot to Butta. Then when it discharges to 80% or so I start the process again as stated. Sticking with these procedures has prevented the no-charge / no-boot issue from reoccurring. I also no longer charge the Touchpad at night. Instead, I charge it in the morning or during the day and only leave it on the charger for an hour or two until it is fully charged. It is my understanding that technique should result in longer battery life and better (longer) charge in the battery.
When my Touchpad battery has gone completely dead it is a real pain to get it to charge up the battery again. When the batter is totally dead the device will not boot into any OS or allow me to even get to the boot loader program. Takes a lot of messing around to get it to start charging again. Though I have been able to, eventually, get it to boot into WebOS and start to charge. But this was not an easy process by any means.
Also, I would agree that you really need to get a stock charger with the cable for your Touchpad. Using a different charger could damage the battery in your Touchpad and/or cause the battery to charge too slowly.
Good luck!

My Hp TouchPad tablet came today and I was told when bidding that it was doing exactly the same thing as mentioned here. I have the OEM charger and cable.. I'll let you know when I can get it straightened out and I hope it is a good one.. Thanks for the info..
While on the OEM charger it booted and I selected webos for the tptb to reflash A6, but soon after it was off charger it went back to the battery icon. battery life low I guess? I selected shutdown. Let it charge over night and see what happens.
Many thanks to many members who are so helpful...
I have my Desire 510 plugged into a wall outlet and I keep getting the message "Unable to charge your phone because it is using too much power. To fix this problem, reduce power consumption by turning off your phone, closing any apps you aren't using or turning off the screen"....I am rooted, have TWRP installed and a custom ROM. (Raptor ROM v1 since v2 link asks for a decryption code)...I have turned on Power Saver, Mobile data and bluetooth are disabled. The phone is losing battery power even while plugged in. I have tried 3 different chargers and outlets
EDIT: Went back to Stock ROM and its STILL having charging problems....

I've had this problem and it stopped when I took a plug from a Verizon phone and used it. It's the plug where you cannot remove the wire and plug it into a PC or another charger, but as long as you save yours, you should be ok. NO other plug would work!

I have it plugged into a wall charger and its still giving issues (power brick with non-removeable USB cable)...i've had this phone for about 30 hours and been plugged in the whole time (minus the time it took to swap out USB cables and outlets) and it's not even gotten a full charge....i'm just gonna buy another phone.
EDIT: Just ordered a Motorla E (2015) to replace Desire 510....this phone will be thrown in a drawer
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:
