I realize there is a bug in CM9 related to charging.
I was doing this on a friend's touchpad, and it's become un-usable.
It would trickle charge in Android / WebOS when connected to computer, but the Wall charger did nothing at all (regardless if powered off / android or webos).
The wall-charger is the only power supply she wants because she is travelling for a couple months. Computer trickle charge will not do.
I ran ACMEUninstaller to get rid of android, but webOS and wall-charger still isn't doing anything.
The webos + computer is trickle charging still though.
I threw on CM7 in hopes of having that clean something, but something still isn't right.
I uninstalled CM7.
Anyone else experience this?
Right now I only have webos installed, and only the computer trickle charge works.. :/
I am going to try running web doctor in a bit, but I need 25% battery before it'll work. I thought I'd throw up a question in case someone else has a response.
Did you try another power supply? If it charges via a PC connection but not the wall charger I would say you have a bad wall charger, or bad USB cable.
Also try rotating the plug end of the charger and then rotating it back to click into place. Sometimes the charger won't work because it isn't engaged properly.
Similar problem
I think I'm having the same problem. I got my TP yesterday from the woot deal and installed the most current CM9. I noticed today trouble with the charging. I plugged it in overnight and it was at 70% this morning. It charged very slowly plugged into my pc during the day, but this evening I plugged it into the charger for several hours and it's at 48%. I just got this thing, is it possible the charger brick and/or cord is bad already?
Update: well, after trying about 15 combinations of cords and charger bricks I found my HP USB cord is the culprit. Not sure why it lasted less than a day, but oh well I'm glad to see it's charging now.

The HP USB cable is not particularly good quality. .. Mine died after a couple months, many other people have had the same happen too. Though having said that, the replacement cable I got FOC from HP is still alive and well.

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).
So I have a streak 7 wifi only model. A few nights ago I upgraded manually to HC 3.2 with no problems. System seemed normal and everything in life was good. I forgot to charge my streak and when I woke up it was dead as expected as the battery was already low. So I plugged it in and let it sit for a few hours. Didn't even occur to me the light never came on for charging. So I figured I must have forgot to plug it in. When I looked it was plugged in correctly. So I plugged it in yesterday and let it sit for 24hrs and still no juice in the battery. I have tried unplugging the cable and reconnecting. I have tried using the power reset pin. I have tried different usb charging adapters. As I said it is dead so I can't get into the recovery menu to perform a factory reset. The power cord I got was just shipped to me on Tuesday Oct. 4 from Dell and worked fine when I first used it. Any help would be greatly appreciated.
Try this as it may not be the cord but the converter itself. Plug in the USB to a computer that is ON and RUNNING. In other words...not in sleep mode. Let it sit for a few hours and also note if the light comes on. It just may be the converter may have gone bad. Also try by resetting in using a needle and push it in the small hole to reset it.

Do you have the original charger and the cable that was received from Dell is the right cable? I had one shipped from China and all it does is trickle charge, the original cable from Dell that came with my unit charges it in less than an hour on the same charger. Make sure your charger has at least 2 Amps output, cheap 1 Amps will only trickle charge

I want to thank you both for your responses. I have had it charging for about 3-4 days now and it has not worked no matter what I try. I called Dell and they are sending out a new unit. It is scheduled to arrive today.
Plug a charger and force power off with a button(A small hole) next to SD card. Mine sometimes freezes not responding after screen off so I just do this trick, power on it and OMG it works
Cheers
Thanks - this worked for me
hello everybody!!!
about 2 months ago i modded my buddy's touchpad for him and everything worked fine. well he brought back the tp to me and saying its stuck and it wont work for some reason. also i am not able to charge with any usb cable it keeps saying
"to reliably charge, use the cable and power adapter that came with your device."
i just want to charge this thing up and remove classic nerd ics from it and simply make it stock web OS cause its become too laggy and glitchy for some reason and i dont know why. well to be honest i havent used it much this is feed back from my buddy.
i just need to get this back to web OS in a couple of hours cause he is a truck driver and needs it on the road. please let me know thanks

In WEBOS it will only charge with an original charger just so uou know..... in Android you can charge with most anything but anything less than 2amps and 5.5 volts is just gonna trickle charge
As far as the Android install it probably just needs an update and clean boot but if you took the time to tead you would find that WEBOS DOCTOR is used to wipe android off the Touchpad
Sent from my cm_tenderloin using Tapatalk 2
So is the battery dead or are you able to turn it on? The TouchPad needs a certain amount of poswer to charge the device. Thats why the TouchPads original charger has such a big adapter. You chould probably get a slight charge with other chargers but it will take a long time to charge.
As far as android being buggy, I would suggest the same as cdzo72 and just reinstall it. And also like he said, the webOS Doctor will get rid of android. There are also apps in preware, I believe, that remove all traces of android after you uninstall it.

the battery is dead and it wont turn on im trying with orignal hp touchpad charger but there is no power...what to do next ? like its completely black there is no power at all not even a battery sign of charging or anything like that
I'm having the same problem as stated. My battery completely drained. When tried pluggin in it gave me the message "plug in original charger" which I have except for the cable. On the home button I had no chargin light. After a couple of hours I tried turning it on pressing power+home and I got the red battery, then immediately the plug in symbol, then the "plug original charger" message.
Then I decided to plug it to my laptop. The home charging light finally came on stating that it was charging. It's been a couple of hours and I was able to plug it back to the original charger on the wall and the home light continues to show that it is charging. Unfortunately, I've tried to turn it on and I still get the message. I'm going to let it sit for a while to see if it's just not charging fast enough to even power up. I am running CM9. Not planning on going back to WebOS anytime soon. If I get it working, I will let you know.
Oh, if you have the original wall adapter, you can unscrew the actual plug off the adapter by turning it counter clockwise. Then screw it back on. Supposedly that will fix something with the actual wall plug. I don't know if that's what caused mine to actually work again.
If you regularly charge it with a Touchstone charging stand, take it off, and plug it in through the outlet and the cable that came with it, and be sure to try charging in WebOS instead of Android.
I did research other similar threads, but so far I didn't find someone with similar problem like mine, so I opened this as a new topic.
So, my Touchpad displays 0% charge, and it can boot up to Android or WebOS while on cable, but it is refusing to charge. I've used HP Touchpad battery android app and it displays charging current as 0, and capacity is also 0. If I unplug the charger, it will shut down, but if I plug it back again, it will eventually boot into Android, but stays at 0.
It all started few days ago when I've plug the charger, it displayed that it is charging, but capacity was going down. So, I left it on charger overnight, and in the morning, it displayed 0, but still was on.
I've tried with charging it again, changing cables, trying with my HTC 1amp charger, 500mamp phone charger.. nothing helps.
I use ecigs, mech mods, and I use IMR batteries, and had one or two dying since I over discharged them bellow 2V. Once I managed to get one alive again by leaving it on my LiPo charger overnight, eventually it came back.
So, is my battery dead? Any suggestion, since I tried what I hoped it could help? Buying new battery and replacing it is not what I look forward to, since maybe it will be cheaper/less hustle to get new/used tablet. I love my Touchpad, would hate to have to ditch it.
What is confusing is that it can boot up when on cable..so there must be some current detected, but it displays charging current as 0.

So I assume that you've already tried charging the Touchpad using the original HP charger while running WebOS. If that is true and it still won't charge then I suspect you're right and that the battery is toast.
Yup, tried charging in WebOS, too.
Well, only think I didn't try is to find another 2amp charger, maybe my HP charger is toast, and HTC 1amp charger can't put enough current for battery app to detect.
I love my Touchpad so much, that maybe I would get a new/used on of a fleebay if this one is really a toast.
EDIT: Well, Apple gear is really made of unicorn dust While I was typing my response and browsing ebay for a replacement battery, I plugged touchpad to my old MacBook Pro 17". That is only thing I didn't try yet. After 3-4 hours, I tried to turn it on, and it was at 2%! Plugged it to original touchpad charger and it dropped to 1%.
So, probably my charger is toast. Also, interesting that trickle charging using usb port but not using HTC charger worked, and both are/should be 5V - 1amp.
Anyway, added this and will report final result just for the archives sake, maybe someone will run into this issue.
For the sake of the archives, conclusion of my problem
I think I nailed it to faulty USB port on the Touchpad. Trickle charging is working, even with original charger, but original charger doesn't provide enough amps.
Also, when I've plugged in Touchpad to my Mac or Win tablets, I got no popup to mount my TP...not in WebOS nor CM. Basically, both data and power part of USB connection is faulty, cables and charger are OK, so I concluded that my USB port is borked.
I've bought Touchstone from ebay, and if I'm right, I'll be able to charge it like that, and use Airdroid to transfer files from it.
I have a rooted Nook HD with cm11 using nightlies (I forget which one. I think it's 2/1/2014). So, I lost my Nook HD wall adapter and started using a different one. This one had the exact same output specs, except it had .7A instead of 1A. Then it started to not acknowledge that it was plugged in and charging. I usually leave it plugged in overnight, so I found an old Nook HD adapter (I had replaced it a few times) with loose hinges on the two prongs. It was at 95% at night, then at 12% the next morning. Later, I was out somewhere and it said the battery was at 1%. I didn't really think much of this because the green (100% charged) charger light was on whenever I plugged it in, and it has said it was at 1% before, and when I plugged it in it usually fixed it and it would display the correct battery percentage. Well, this time it didn't. I guess I had forgot about the incident the last night. I assumed it was at 100% and it would just run down normally until it died even though is said 1%, but then it died quickly. I plugged it in where I was, but I had to go so all I saw a green light on the charging light, but then I had to unplug it. When I plugged it in later at the house it showed green, orange, then turned off. I left it overnight, and plugged it in this morning and it still did the same thing. I left it that way. I just tried plugging it into the computer because I've heard that some devices use different hardware to charge via just USB, but no luck. I plugged it back into the wall. What should I do?
P.S. Before root, and when I first got it (used), I tried charging it when it was off, and it didn't charge. I never tried again. Is this normal, and could it have somehow contributed to the issue?
OK, I know that it had said I posted the above at 4:00pm. I didn't. Can someone please respond?

Not sure what to think about this and guess no one else as well.
I assume with providing less power the electronics can compensate. Obviously, brown outs (for instance) are bad over a period of time but not as quickly as this.
More power is probably much worse.
Just don't think the charger broke the device. If you find the bn wall plug and it still didn't charge then it physically broke probably coincidence or not.
Addition: Assuming you use a smart phone why not use that wall plug? That's all I use. The bn plug is in the box.
Got a new cord and it works! It was on sale for 50% off as well. Guess I broke the cord by usinng the wrong adapter. Anyway the specs are actually something like 5.1V 2A, and the one I used was 5V .7A. Ouch. Thanks anyways!
