HP Touchpad Not Charging.

SCPadgeebar · January 13th, 2013, 04:43 AM

Hello guys,
I'm new here at the HP Touchpad Section but not new here in Android Forums.

I am running CM7 on our HP Touchpad and my little brother has been fiddling with it(downloading many apps from the playstore using my personal account, thus forcing me to create a new google account/other shiz).

Then one time, the screen kept turning on and off without us even touching it. Our guess was it was dust on the screen which is being registered as touch.

After a week or so that that was happening, the touchpad ran out of battery and was not charged right away.

The result, it won't charge anymore.

Is there anyway to open the device and shock the battery? It may be a dead battery just like what happened to my sister's iPhone.

I've also been reading some charging issues with CM7 and CM9 and tried some of their troubleshooting methods but non worked.

If I just get a little juice to boot it, I would reboot back to webOS as fast as I can and uninstall CM7.

Thanks in advance,
Raphael

You NEVER want to run a Touchpad's battery dead. They don't always make it back easily.

There are a number of threads on Rootzwiki for dead Touchpads. Holding down the power and home buttons for over 30 seconds and making sure you have a good usb cable and the stock charger is a must. Some times it takes most of a day to charge a dead Touchpad. <-- this is the first thing to try.

My wife ran her's dead once and luckily it started up again after an hour of charging. Last time I checked it was at 6% so I averted the problem again. The next build of CM10 will automatically power off at 3%.

Some people have to do this to bring them back to life: TPDebrick v0.1 - HP Touchpad - RootzWiki You might find some hints to get it to power up there too.

Thanks for the reply, colchiro. Will try that on the weekends since I am very busy with school works.

Already sorted it out the other night/morning.

Glad you got it working. What does this mean?

After 2 hours or so, use that charger for the HPTP to charge the touchpad from a used/electrified wire.

I just read it from the article I read.

I guess it means that the cord I am using should be used for a period of time so that I will be using a wire that electricity just traveled so the wire is a little bit juiced up.

I found that the charging connection on my Touchpad is not real good at times. Need to watch the charging icon to make sure the Touchpad is charging. If I don't do that, then sometimes the tablet will go to zero charge and then it becomes a real challenge to get it going again. Also, found that switching to WebOS when charging or when shutting down if the tablet charge is 20% or less seems to be a good idea. Less chance of the tablet having loss of charge or not able to charge issues when I do this. Bit of an issue to switch back and forth between operating systems but not too bad. Recently, while on vacation, I did not notice that the charging connection was not working and the tablet would not do anything the next day. Took quite a while to get it going again.

There is no such thing as juicing up a piece of wire with electricity. What that guy wrote in that thread is totally bogus. What happened to him was totally coincidence and had nothing to do with switching two usb cables between two different chargers.

Have you tried a different usb cable to make sure it is not your cable. HP usb cables are notoriously flimsy.

This app (by the same guy who is developing our CM roms) will tell you if you're charging or not: Goo.im Downloads - Downloading TPChargeTest-v1.0.apk

I use my TP usb cable and charger all the time, for multiple devices, and have never had an issue with it, however, if you bend it a lot, like tucking the cable under the tablet, making a 180° bend, or yank it out of the device a lot, it will fail.
