[TouchPad Q&A, Help & Troubleshooting] sShadowSs:
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.
