Hi, I have a tf300t since 2012, and have been literally using it a lot, even though that this problem isn't as common as it is, well, recently it happened to me after using the universal fold case that I bought for the tablet 6 months ago or so.
The main problem is that the power button (the plastic part of it) is now more shallow because of the handles that press and hold the tablet, one of the handles are located WHERE the power button is, which leads to it being more shallow and problematic to use the tablet..
I will provide pics soon but, is there any solutions to this issue?
I had same problem. I sent it to Asus to be fixed. Thinking what happens is the switch unit gradually moved and just needed to be reseated and fastened.

Never mind, I fixed the problem myself after discovering that the button foil was not centered, I recentered it manually and fixed the problem this way.

I've been experiencing an issue with the Home button since the day I got the device.
A few times the Recent Applications screen has popped up seemingly on its own, while I was in the middle of doing something else. At first I thought it was just a software glitch and carried on. The haptic feedback pulses twice quickly. The backlight of the Home button turns off, the backlights for the Back, Menu and Search buttons stay on, the Back, Menu, Search and Home buttons no longer respond to touch or generate haptic feedback, essentially paralyzed. It remains this way for approximately nine seconds before the Home button lights up again and the all of the shortcut buttons become responsive again, otherwise the only way to get out of the Recent Applications screen is to either cycle the power button and unlock the screen, or select one of the recent applications.
I have figured out how to reproduce this problem by pressing around with the very tip of my thumb along the seam where the glass and plastic lip meet with a little more pressure than normally necessary to register a touch. I am careful to avoid touching the normal hot zone for any button. I start from the far left corner under the search button, and make my way towards the home button little by little. Somewhere between the Menu and Search buttons when I release my thumb after pressing firmly, the haptic feedback pulses twice and the issue occurs. I can reproduce this issue anywhere along the edge on the bottom right half of the phone and about 1" up the right side of the phone, far from the Home button.
I suspect there is something wrong with the capacitive layer of my screen.
Please see if you can reproduce this or something similar on your phone, just bear in mind that you will need to press firmly (not too hard but not soft).
The unfortunate thing about this problem is that it can be activated inadvertently while gripping the phone during normal operation, interrupting whatever you are doing for the time it takes to resolve itself.
This is literally the only issue I've had with the phone in the week I've owned it and I am considering whether or not I want to play russian roulette with exchange units (and other issues like bad screens and bad weak back buttons) because everything else seems to be perfect.

Same thing happens with me on the swap unit I got today. Bummed like no other.
Tried replicating this with my device with (thankfully) no results.
one and one... I wonder how many other phones are affected then, and how many people have it but haven't noticed yet, e.g.; "you're holding it wrong".
Hm. Just tried to replicate this on my Nexus S, no issues.
Mine did the same thing at least twice a day. However, it has not happened again since the GRH78 update. (Knock on wood).
Have your received the update?
This just happened to me for the first time about an hour ago. I have the new update too, sadly.
Yes I have the update.
I can't replicate this problem, but nonetheless, it still happens.
I have this same problem with my back button. I can't replicate it but it just randomly happens to me. I have the update and I also tried using Paul's Tom and it still happens.

This happens with my back button.

happens to mine too, also the home button. doesn't bother me too much, though. and I also have the update.
I had something even weirder tonight.
I did a factory reset, then proceeded to install everything back on when I noticed that my home key wasn't doing its job at all. Still had the haptic feedback so the input was received, but it did absolutely nothing. So I did another factory reset and that seemed to have cured the problem. My home button is working again (but i still have the other problem from time to time)
Had it happen again inadvertently today, if you notice from my video the spot where it can be activated next to the Maps icon also happens to be conveniently where your finger ends up when swiping to unlock. I was holding the phone one handed and unlocking with my thumb and it triggered the problem. Might try for an exchange this week. It shouldn't behave this way.
For those of you who are experiencing it with your Back button, does the backlight turn off for 9 seconds on your Back button?
I don't know everything about how the hardware works but I'm guessing that there is some kind of short, the controller for the capacitive layer gets confused and resets. Could explain why it takes the same amount of time to come back to normal every time. It also seems like it might be related to case/screen flex, where pressing on a part of the case bends the capacitive layer just enough to short the circuit.
This issue came on my two days old Nexus S too, but with the back button. It has happened two times now. I think that's a software issue that come along with Gingerbread. It's something like it registering a touch and sometimes the OS think it was the buttons that were pressed...

Does your back button black out for ~9 seconds?
I haven't had any button issues whatsoever since I got mine on the 24th.
No, more like two seconds.

Here's a new video shot today showing the issue occurring with only normal light touching:

Also last night it happened while I was inserting a cable into the headphone jack.
Haven't seen this one anywhere here on XDA yet, but I did find one other person through google that has my same issue. So, here is the problem, when you slightly press on the screen just below where the power button is, either the screen turns off or the power menu comes up. This just happens to be exactly where I put my thumb when holding the tablet, so I constantly get the power menu or turn off the screen on accident. This is an extremely frustrating problem, it happens non-stop right now. I've also noticed that the power button itself is messed up too, in that I don't even have to push it. If i just barely touch it with my finger it turns off the screen, it's like the button is stuck. Of course, I have already unlocked so getting a warranty replacement is out of the question. Just wanted to put this problem out there so other people know about it.
PS. anyone know of an app that will disable the power button? If not, I guess I'll open it up can physically disconnect it or something, just make sure it never gets turned off!, lol
How would you implement it?

how are you going to turn it on/off if you disable that button?
Well, I seem to have fixed it for now. The power button is actually three pieces, the plastic button, a small sticker with a tiny piece of foil on it, and a tiny contactor on the circuit board. The button pushes down on the foil, and this connects the two piece contact on the circuit board together to complete the circuit. It looks like the piece with the foil was too tight over the contact on the board, so anytime any pressure was put on it in the area of the power button, it would make the connection. I simply pulled the foil piece off (the sticker), and stuck it back on, but more loosely than before. For now everything works correctly with no accidental power button pushes. However, all the little plastic tabs that hold the back on the tablet are apparently one time use, because they are all broken now, and the back is barely hanging on. Guess it's time to find a case that I can use with the dock so I don't lose the back off this thing!

Good fix, perhaps some glue?

My mobile dock is malfunctioning to the point where I can't even use it to type since it appears as if the majority of the keys are mapped to other buttons and some just plain refuse to work. [Example:- '2' Key inputs both '2Q' simultaneously and also turns on the bluetooth, Backspace key turns the pad off and 'Y' key takes a screen shot. :S]
I've no idea how this has come to pass and I'm somewhat confident no liquids or damage has happened to the mobile dock....or atleast not on my behalf. The only thing i've done out of the ordinary is keep my infinity tablet plugged it into it pretty much since I bought both tablet and dock late this summer.
I've done a cold reset using the power and volume buttons and as far as I know I've all updates...I'm at a loss as to what to do next, especially since I can't seem to initiate or find proper information on how to initiate a download of Mobiledock firmware if that is indeed the case.
I don't live in America so taking it back to 'best buy' isn't an option right now short of ordering a whole new mobile dock, despite this one still being able to accept and utilize USB devices for game controllers and external hard drives.
Don't know what to do...Hope one of you guys can help me.
Cheers.
Send it back to Asus. It should still be covered under warranty.

In the end I just bought another dock, which I'm currently using and typing on now. I'll do as you said and just send it back. I'm sure that was one of the faulty ones with the chipset malfunction that caused it to drain battery life as well.
Cheers for the response, mate.
Hi all I was wondering whether any other people on here have been suffering with a temperamental power button with their HTC ONE S?
Below are my symptoms whether the rear top cover is on or off. HTC also sent me a replacement cover but I still have the same symptoms so think it could be hardware related.
Press power button from sleep mode and:
Wakes sometimes*
Doesn't wake sometimes*
Sometimes screen ghosts quickly and sleeps again
Wakes and then sleeps
Press from awake and:
Sometimes stays awake*
Sometimes sleeps
Sometimes sleeps and wakes again
Holding power button does nothing with the cover on or off. It will either sleep straight away or sleep then wake. It will not give me power options or screen shot function.*
I have heard of Nexus power button issues but anyone with a One S experienced anything similar?
If you still have warranty replace it while you can

Thanks for the reply. Yes it is still in warranty so will have to send it for repair
Your service provider doesn't do warranty exchanges?
Sent from my HTC VLE_U using xda app-developers app
better to have it exchanged rather than sending it for a repair.
its a QC thing.
HTC have offered to repair it, I've only had the phone for 4 or so months although I'm 14 months into my contract. I originally had a SE xperia arc s but it had to be sent away for repair, they gave it back still having problems so replaced it. This also had problems so phones4u offered to repair this one but I refused and eventually got them to agree to replace the phone with an HTC one s. Now I'm having problems with this and they are bound to tell me they will only repair it.
Umm, don't know where's the limit to resurrect an old thread... . Also sorry about maybe a bit too long text, I suck at being concise
Anyways, I have the same symptoms on my phone. I have found several threads with the same problem, but here's just a bit of information I couldn't find elsewhere.
In short: I believe the power button goes deeper in its notch behind the SIM tray than it is supposed to go and the contact to motherboard becomes misaligned. i.e. the switch itself that is right next to motherboard, this has nothing to do with the back cover.
I conclude this, because I noticed that my power button doesn't protrude as much as it used to - and then it stopped working altogether. I was on a plane when this happened, so I was forced to do this little experiment:
I removed the back cover and lifted the power button just a little bit (maybe 0.5 - 1mm or so) - and it started working again! But only for a while, as in regular use the power button goes deeper again over time and loses contact. The button moves very easily in my case, so don't use force - maybe your power button issue is caused by something else, and the glue (if there ever was some) is still intact. Lifting it it might come loose even if it wasnt - or worse, you might break the power button mechanism!
If you can lift the power button (mechanism behind back cover) and it helps, you have the same issue as I do. Please do tell here, maybe this is a common defect. Of course, if your phone is under warranty though, maybe its wiser to take it back to the store before fiddling with the switch .
Or, maybe it's supposed to reside as deep in it's notch as it goes, but there's some oxidation happening in the contacts / MB; lifting it causes the contact to be in position where there's less oxidation. But as my phone is < 6months, I believe there shouldn't be that much oxidation yet (maybe after five years or so it could be expected) - I've never moisted the phone or anything like that. Also since my memory tells me my power button used to protrude more when it was new, I believe some glue (or plastic) has failed.
Cheers!

Actually, now that I've found this:
@3:19- It seems in the video that the power button is soldered to the motherboard. Mine is definitely loose, but does work (if not all the way in). So you might NOT want to pull the switch module after all.
Thanks for your input.
The new back cover made no difference to my issues with the power button. I spoke to phones4u who were reluctant to change the phone but after a short conversation telling them how many faulty phones I've had on this contract they soon agreed to swap the phone with a new one.
As you'd expect new one works fine. I believe it was definitely a faulty power switch on the phone.
Hey guys, yesterday when I pulled my phone out of my pocket, I noticed the power button wasn't working. Upon closer inspection, it is jammed and will only register a press if I really push on it hard. Then I realized the volume buttons were the same exact way, which is strange because the phone has been in a case its entire life and is immaculate. But anyways, has anyone else encountered this? I tried doing a search but no results. The power button works if I really put pressure on it and only the top volume button works if I press it hard as well. The camera button is perfectly fine.
I purchased this phone brand new from T-Mobile November 2014, it may be time to upgrade...
Some cases cause this problems as they put consistent pressure on the buttons
Just experienced this last night. No idea what's caused it. My phone lives in a case with a power button cutout so there's no pressure on it. Odd, and irritating because thus phone is perfect otherwise, and the first one I've ever had that I still liked after 18 months.

Probably either broken button strip, or it has been dislodged from its mountings. You need to remove back cover, then battery and you can see whats going on.
