[Q] The buttons won't work. - Galaxy Tab 2 Q&A, Help & Troubleshooting

Hi, recently, my siblings were playing with the tablet, I didn't know what happened to it, but then my brother showed it to me and the power button seems to work, but it won't turn the screen on, and the big volume button is sticky, both doesn't work, I'm guessing they spilled juice in it or something. So is there anyway to fix this?

Open it up and clean it out? No I have no idea if you can still unlock the screen then you should be mostly Ok. The power button is important

If the screen turns off, I have to plug in the charger so it turns on.

[Q] Help Needed : Can't turn on?

My Transformer was working fine, battery fell below 9% so I put it to sleep and plugged it in...
Now the device will not turn on, back of unit is getting warm?
Well, the warmth will be the battery charging. No issue there.
See one of the half dozen threads about not turning back on.
It came back to life, after holding the power button still seemed dead, then i plugged in a HDMI cable and it turned on.
My power button is finicky... every thing else seems perfect...

Mine does this. You have to power off completely. To do that, you must hold the power button for more than 10 seconds to turn it off. Wait a bit, then power it back on by holding the power for 5 seconds.
I've searched around and people say it's the lock screen that causes the screen to blank. But I don't think that was it, I disabled it and it still does it.
Next someone says it has something to do with WiFi, I don't think this is right also because it has happened at times when I had the wifi OFF.

Are you saying before charging you power it off completely or always?

Can u not get into bootloader or recovery keep trying for a little. And does yyour computer recognize it
It may also be the proximity sensor. If you have case on the phone remove it also try cleaning the screen the sensor is located on the very top of the screen approximately 1/2 an inch to the left of world at&t logo give it a really good cleaning and see if it comes back on.

HTC Sensation Power Button (On/OFF) doesn't work.

Hi everyone. Today i was chargin my phone at PC using a no-name usb cable. I've noticed while it was charging that the screen kept turning itself on and off. When i finaly took the phone, the screen was unlocked and when I tried to press the home button it did nothing but taking screenshots (like the power button was stuck). The power button was not wroking either.. After I took out the battery and restarted the phone, the power button didn't work at all. Tried to clean it off using this method but it did not work. Tried to clean the power off button using a method i've seen on google (can't post the link since i'm a new user) but its still not working
I'm desperate, please help
Are you sure, that the problem is only the power button? I have sometimes problems with this phone too. Sometimes you can't turn it on.
Try taking the battery out for at least one hour - then try to start it. I had always success with this.

The batter has proven me to be fcked in the last week, had lots lots lots of random turn-offs and restarts. But for more than 5 hours the power off button didn't work.
I'll let my batter out through the night.
Thanks for reply.
PS: I'm running ARHD 7.3.

The restarts can also result from a loose battery. Try putting a folded piece of paper between the battery and the upper casing of the phone, so the battery is pushed against the pins. This is a well-known issue. It helped me a lot. Before I had also lots of reboots.
Yep, did that in the last 1,5 year and the random reboots stopped. But as i've said, now it happens even tho' i have a paper that keeps the battery steady.
Lol just took the phone to see if the power button works and currently i'm talking screenshos pressing the home button .

How did you turn on your phone if the power button doesn't work?

I take the battery out, put it back in and after a few seconds the phone turns on.

Well, this isn't normal. Is your power button constantly pressed?
Try the following: Hold the volume down-button while inserting your battery until the phone boots up.
Does it boot into the boot manager?
Just woke up, plugged my battery in and the power button worked almost normally. Could've pressed it 5 minutes and after that and a restart it didn't work anymore.
This means I should buy a new battery and everything is fixed? Are the Anker batteries worth it ? Or do you recommend me a HTC EVO 3D battery ?

You can use the battery from the Sensation XE, which has 1.700mAh instead of 1.520 (or 1.560). At the HTC-Store they are about 50 € here in germany.
Always buy original batteries! Not the cheap ones from eBay. They usually don't have a temperature sensor, so the phone can't shut down, when it gets too hot while charging. This can be very dangerous.
I haven't got any experience with Anker-Batteries - sorry.
Pressed the volume down button and it got me into the boot menu (just like the power button is kept pressed).
Do you think that if I change my batter it will fix my problems ? Also noticed that my battery is altered, aka its not flat but swollen.

If it is swollen, it is definitively broken. Mine had the same symptoms...
I'm pretty sure, the powerbutton-problem isn't related. Does the button feel normal, if you push it? Or is there no "click"?
Maybe you can repair it with a needle by lifting the foil a tiny bit.
i dont think you need a new battery, same problem occurred with my phone, done some DIY fix and written that in a post for fellows like you in search of help.
here is the link to it:

A new battery has fixed it.
No problems with the phones until now. It works perfectly

Unbelievable!!! Thanks for the link above - it worked for me, the power button is fixed...

What happens if you just hold the power button down for about 15 seconds?
Or, if you hold volume down and power for 15?
what about if you hold volume down and plug ausb cable in from your computer, will it enter download mode?

Thank you very much needed bro
As info, the AT&T thread is short of limited. I usually stick to the normal G2 thread, myself. You'll get more help and quicker responses I think.
