Ok, So my Shield Tablet has been great, never any issues until today. I was just browsing the web, gaming a few games, not installing anything or messing with system files are anything like that, and out of no where my power and volume buttons just stopped working! Heres the strange part though, they only stop working once the tablet is booted up. They work fine to power the tablet on from a cold boot, and they work fine in recovery mode (volume and power buttons), but one the tablet it booted the stop working. The only way to get the screen to wakeup once booted it by removing the stylus. To power down or reboot I have to use the terminal emulator, or hold the power button down for 10+ seconds to force a shutdown. Just pushing the power button once the tablet is booted up does nothing (it should either turn off the screen or bring up the power/reboot menu), same goes for the volume buttons, once booted they stop working. It has to be a software because the buttons work in the recovery. Has anyone else seen anything like this, and/or know how to fix it? I REALLY don't want to have to do a factory reset....
Never mind! I figured out what was wrong. I caused the problem and just didn't realize it. About a week ago, I was trying to use a ProEX brand Xbox 360 wired controller with my tablet using a USB OTG cable and for some reason the right thumb stick was being mapped to the trigger buttons. So, long story short, I copied all the info from the Xbox 360 controller map file in android and pasted/overwritten all the map settings in the Generic.kl file (which is what the ProEX controller was using for its mapping). By doing that, I basically accidentally removed the Power, volume up, and volume down key mapping because those keys are mapped from the Generic.kl file. I just didn't realize that's what caused the issue because it didn't take effect immediately. It only took effect after I rebooted the tablet several days later.
Also, this is kind of a double post, so if any mods would like to, please delete this thread. Thanks

Hello everyone! The problem is power button on my Asus TF. It needs to be pressed veeery hard and still it unlocks screen like only from 4th-5th attempt. That's annoying I would tell.
Is there any possiblity (tool for example) to make TF wake up from volume buttons (like in cyanogenmod 7) ?
Rooted 2.02 Prime ROM
Thx in advance for any help!
UPDATE: Just what I didn't want this issue to be, I now have a hardware power button issue. Not a software one... Guess it's RMA time!
I'm not so sure it is a hardware problem. Let me explain my situation.
My power button doesn't turn on nor turn off the tablet anymore. I cannot do a hard reset with the power problem depressed for 10-12 seconds like I used to be able to do. I'm not rooted otherwise I would use the Quick Reboot app!
I never had a hardware problem with my power button until just recently. After the 3.2.1 ASUS update it appeared that everything was fine, but a rogue app crashed the tablet (can't remember exactly which one, but I think I was installing some Equalizer/Sound apps to help with the speaker volume) and things weren't the same afterward.
I now have no way to power on the TF with the power button and need to attach the charging cable or dock for it to wake up!!!! Very annoying! I also cannot shut it off unless I let the display timeout or attach the dock and hit the lock key!
I've let it run down to 0% battery and then have had it do a (hard) restart, but that allowed the power button to turn on/of the TF for only a while. So I'm thinking it may be a software issue. Perhaps from the dock sleep fix we got from the latest ASUS 3.2.1 update?
Anyone else having issue with their power button? Would rooting help if it is a software issue?
Seems like your problem is not hardware yeah. Sorry for you, that should be rly annoying.
But mine i'm sure is hardware one ((
send it to asus for repair. i had the same problem and got it back
within 5 days. now everything is working well.
Well I did RMA the device today as the power button had become totally non-functional; I couldn't turn on/off the tablet nor could I do a shutdown (hold power button for 4+ seconds) or Hard Rest (hold down power button for 12+ seconds).
This time next week I hope to have my tablet back...
I have a weird problem where the power and volume buttons don't work when the screen is locked. I know it is not a hardware issue because I had this problem for a couple days, then the power button started working again perfect the next day and now its back to not working. When the screen is unlocked, the volume keys work perfect and controls volume as it normally would. I downloaded some apps to enable the volume keys to work as an unlock button, but they fail to work.
As a last resort, I was going to flash a new rom to see if it would help, however when I boot into recovery mode, the volume keys don't work and i cant move up and down through the options. In addition, I've noticed that when I do a battery pull and put the battery back in, the phone automatically boots up as if the power button was held down.

Your power button is failing. It is a hardware issue. Send it for repair.

Do you have an idea of why the volume buttons aren't working though as an unlock button with apps tho? I also question whether it is a hardware problem because this has happened in the past before and then suddenly the power button works again perfect for months. It is just very annoying for me to sit here and hope for it to start working again.

It's a known issue that when the power button stay stuck the other buttons don't work. It sucks, but that's what it is. Nexus S always had this power button problem and usually you can send it to samsung to get it fixed. Some people have tried to fix it themselves without too much luck...
Hey guys,
I unlocked my TF700T using the Asus unlock tool, then rooted it with Kingo App.
I opened a terminal on the device and ran "su" to verify that I had root, which worked I did.
I then installed com.keramidas.TitaniumBackup ("Titanium Backup ★ root") and began a full backup, but at 65% my Internet connection dropped (not sure if related, but interesting timing) and the system froze. After 10 minutes at 65% I powered off the device in an attempt to reset.
However, the device now will not start. The screen remains unlit. Charge LED will not light. Holding Power for 6 seconds and holding Power + VolDown result in a short (500ms?) vibrate, but nothing more.
I have not yet tried a paperclip reset, or connecting the dock. I have tried connecting to both USB and power. With USB, Windows 8 detects it as a crashed device (no surprise there) and fails to install a driver.
I suspect I'm hosed, but I'd be interested to learn why.
Any theories or suggestions?
---
Android 4.2.1
Firmware V10.6.1.14.10
Same behavior with dock connected.
After connecting power through the dock, the charge LEDs have both lit.
Ah just re-read and realised you only get a vibration but no screen..... Bummer - not sure what to suggest for that one.
Well, thanks for trying
Sell it for parts, I reckon.

Since you don't have much options, you can try these. I think that there were a few users were running into this problem and tried this. Some reported back that it was not working and some did not say anything. So I don't know if it works or not but you could give it a shot.
Try these combinations:
1. Hold the power button + volume up. You will feel the first vibration and keep holding both buttons until you feel the second vibration. As soon as you feel the second vibration, you need to release the volume up button But you must keep holding the power button. You need to hold the power button until you feel the third vibration. The third vibration is when your device is trying to boot up. You may want to try a few times with those sequences above in hope that it will bring up your bootloader.
2. If the above sequences don't work out for you, you can try this second solution. However, you need to hold both power button + volume down this time with those sequences above. Please report back with the outcome, thanks and good luck...:fingers-crossed:
Hi everybody!
I checked through all threads here about my problem, but could not find a solution.
One day ago the battery of my tab ASUS TF700 fully drained.
So I connected the tab to the charger and in some time tried to turn on it.
Nothing happened, it just started vibrating constantly.
The only method helped me stop vibration is hard reboot (power + volume).
When I hold only power button it stops vibrating for a second, make short vibration, again pause and then starts vibrating.
Connection to the monitor by HDMI didn't show anything.
I didn't do any updates right before this accident.
No root, no unlocks etc.
Please help me, I am desperately frustrated.
PS. there are some old trends with the similar problems, but without solutions.

Can you boot into the bootloader?
Push and hold Volume Down (left side of the rocker) and Power. The tab should vibrate twice, let go when you see tiny script and three icons.
Push Volume Up with the RCK icon flashing. If you get an Android falling over with an exclamamtion mark, you're good: your stock recovery is working.
You probably corrupted your system when you let the tablet crash in the middle of something. If the stock recovery is still working you can re-flash the firmware. Let me know if you can get there and I'll tell you how.

Hi,berndblb!
Thanks for advise.
Unfortunately my asus doesn't stop vibrating when I push and hold Volume Down (left side of the rocker) and Power.
So there are two options:
1. If I push and hold Volume Down (left side of the rocker) and Power,
then it stops vibrating for a while, makes one short vibration and continues vibrating constantly without any interruptions.
2. If I push and hold Volume Up (right side of the rocker) and Power,
then it stops vibrating for a while, makes one short vibration and finanlly stops vibrating. One trick: I have to push and hold till the moment when the device makes one short vibration, and only after the moment when vibration stops finally I can release the buttons.
That is all I managed to discover pushing and holding buttons.
Sorry friend, I think your tablet is hosed....
Pushing Power and Volume Up (right side of the rocker) should get you into APX mode, which is usually the last thing working if everything else is messed up.
But even if you get to APX - it's useless unless your tablelt is unlocked and you previously created your device specific nvflash blobs.
I'm afraid a new main board is your only option....

I have finally won
The solution was simple:
1. I let the tablet vibrating till the battery totally discharged (it took the whole night).
2. Vibration of course stopped.
3. I charged the battery a little and switched on the tablet.
4. Tablet launched in normal regime, all data and system were saved, even after I tried to make a hard reset (I suspect it didn't work out).
After that it only once rebooted without any reason, but that's all.
So several days passed, the tablet works without any problems.

It is good to hear that you have your tf700 back....:good: Thanks for the report back...
BTW, are you going to unlock your device and generate the Nvflash blobs? If it occurred once, It could come back again and hope for lucks again...:laugh: Just my two cents..
OK, my Shield Tablet has been great, never any issues until today.
