Fatal power button issue

Hey there, I have had no problems with my Z2 until today. However, now my screen is constantly flickering on and off as if the power button is being repeatedly pressed, furthermore the window with the options to power off/ restart etc also appear occasionally. I'm unable to power the device off as when I do it will boot itself up again straight away. As you can imagine, this renders the device utterly useless. Has anyone had a similar experience with this? Or does anyone have any fix suggestions? The phone is out of warranty, I'm unable to replace it.
I made a short video of the problem just in case my explanation isn't clear enough.

Thanks for any help you can offer me, I'm lost for what to do.

I had the same issue once with my old Xperia Z, after washing it with soap (which is apparently not right) so water and soap got beneath the power botton and caused the same symptoms. It was also out of warranty and I sent it to 3rd party mobile fixing office. They did some cleaning and didn't cost me a lot that time.

It can only be serviced in the country where it was originally sold. Take it back to the US or send it to someone you know there to take it in for service.

IPhone 5 Power button issues after recent update.

After this most recent update, my power button is not working as it normally does. It takes two or three attempts to turn the phone off and more than once to turn it. Sometimes it turns on and immediately turns off. This is happening only after this update.

Yes 7.1.2 I had a 7.1 backup, and no issues with that... but then I did a clean DL of 7.1.2 and once again with NO apps on the iphone power button issues... as mentioned. So it is not the apps, nor songs, nor anything else...just 7.1.2 I am now running 7.1 no issues.

HT1430 iPhone 4S Power Button Issue

I have an iPhone4S that has fallen to the broken power button issue - is there a way to restart it without the power button? My phone is acting strange and I know if I restart it then it will be ok. I am already using the Accessibility feature to lock the screen, but cannot figure out how to restart it short of letting the battery run out.

I have the same issue.... just hold down the lock screen button on your accessibility menu until it shows you the power down option. Then plug the charger in & it will automatically turn back on.

IPhone 5 power button issue .Apple store can't help !

I have an issue with my power button on my iPhone 5.It works perfectly sometimes and sometimes it doesn't .I have to press it 2,3 times to get it work .I took it to the Apple store and it worked perfectly there so they said they can't replace it unless they see the problem and they are right . But I don't know what to do it does it sometimes ,how am I going to go there in the right time .Do you have any other suggestions ? Thank you.

You can try calling an Apple support number for your location: http://support.apple.com/kb/HE57 and see if they can help. Otherwise, when it starts acting up take it to an Apple store genius bar.
But try the support line first and see what help they offer.

IPod Touch Power Button Issue?

I have an 8GB 1st Generation iPod Touch (The one without the camera, power button on the left side instead of the right, yada yada yada). I've had it since Christmas, and it's run perfectly well, until yesterday. I began to notice that the power button (the small button at the top) was sticky. Not stuck, but simply sticky. Instead of having to tap it and add a slight pressure to get it to turn on, turn off, lock, ect, I now have to push down so hard that it leaves imprints on my fingers, not to mention that it doesn't always respond, as if it's jammed, and if I'm not very persistent it will lock, but not turn off. I have to try three or four times to turn it off using the power button, though occasionally the screen will flicker like I'm hitting the button multiple times. It's not like the button is stuck - I can still use it, but it's sticky. I was wondering if there is any solution that doesn't require sending my iPod in?
If you need any further explanation feel free to let me know, I'll be willing to tell you. Sending my iPod in isn't a problem really, though if there's a simple fix that I'm not aware of (seeing as this is my first iPod) I'd be much more willing to keep it here.

Hi,
I have an 32G 2nd generation iPod touch with a problematic on/off button, and I'm not sure this is a physical problem at all.
My touch worked perfectly well until the version 3.0 update, and then I started having problems with the on/off "wake/sleep" button.
I often have to take 3 or 4 attempts to turn the screen off, and then when it does turn off it comes back on again with the "red bar" to switch it off. This is only supposed to happen when you purposely hold down the on/off button, but it does it when it feels like it now!
Like I said, it worked perfectly well on the version 2.0 software, but you couldn't possibly get into DFU mode to return it to version 2 because holding onto the button no longer seems to get the "red" bar to come up, so I've no idea where I am with it! It drives me nuts, but I'm almost positive it's an issue with the software.
Yes, I've tried a restore on several occasions, and turning it off and on so many times I can't count, but the problem never goes away!
I've asked Apple several times to deal with the issue, but they've had at least 6 attempts now, and nothing has been done about it. My Touch will now be stuck on 4.1 forever as I can't get iTunes 10, because I have an old mac that's on 10.4.11.
I'll have to live with it as it is, as I can't afford to upgrade, and I don't want to anyway because it works perfectly well, EXCEPT for this one annoying issue.

Lenovo T410 does not power on due to keyboard / power button issue.

I have a Lenovo T410 which has been exhibiting keyboard issues (several keys have failed and I've been using an external keyboard).
It seems that the keyboard failure is affecting the powering up of the machine. Occasionally it will turn on, most of the time it will not.
I've submitted an eService request for this and the status is "Solution Provided" but the "SO Status (as shown on ICSS)" is "On Hold" "Order on hold, pending update" (per: http://support.lenovo.com/en_US/research/hints-or-tips/detail.page?DocID=HT074324 ). This has been the case since the 28th of last month.
I've confirmed it is a keyboard failure by swapping a keyboard from a T420 (which, ironically, had a service request fulfilled fine around the same time).
I have two questions:
i) most urgently, is there *any* way I can power the machine on without using the keyboard?
ii) what do I do about the service request's "On Hold" status? this machine is out of action and key to our work.

i) There are three ways to power on the laptop without the power button.
a) Use a dock.
b) Check under BIOS menu (if possible) under power, to see whether you have something called 'Power On with AC Attach' feature. If you do enable it, and save then exit. What this do, is that it will power on the laptop when you connect the power plug into the laptop.

c) remove the CMOS battery, and power on the laptop by attaching the power adapter to the laptop.

Blackberry passport power button issue

hi, I bought a passport phone three weeks ago and this one problem with the power button is there from the begining. there is a delay cca 4 s, not everytime but very often and it is very annoying. Please can you help with this, is a software or hardware issue. Thanks for your quick answer...

I hadn't noticed, so I just looked. I count 1 Mississippi, 2 Mississippi (about 2 seconds give or take) between the moment I press and hold the power button and the moment the screen changes to cancel lock restart option screen. There is a second or less delay to lock the screen and keyboard when I press and release the power buttons, and about the same when I press the button to unlock the screen and keyboard.
See what others say. I bought my Passport when it was first released. I can imagine BlackBerry increased these delays in software based on user feed back, but I don't know.
I would also look at any correlations. I would be particularly curious about what happens with a clean OS install, and then what happens when you install apps one at a time and test in between. Also, if you have any very long text conversations, those have been know to cause sluggish performance, so it would be interesting to know if deleting such conversations makes a difference.

Satellite A660 - Power Button Issue

For some time now my laptop has been power in on and off without any interaction. I think that it relates to a faulty power button. The button is extremely sensitive and will even power if the surrounding panel is pressed.
My question has anyone else experience this issue and were they able to fix the problem? I'm thinking that if I take it for repair it will be a replacement of the motherboard and cost half the price of the machine.

Hi,
I had the same issue on the same laptop.
i know how annoying it could be. A simple fix to it was just unscrew from the back side of the laptop the 4 screws that surround the battery. Give it a try it worked for me so far.
it was like the wind would switch the laptop on or off.
it took me more than 2 weeks to figure this fix out. i replaced everything from RAM , HDD, battery, testing of power supply to all software and still had the issue.
i was just about to break my laptop when one day i had it apart and could not be bothered to put the screws back in and BANG it worked like a charm......
Tell me how you go.
Cheers,

IPhone 5 power button issue

I got my 16GB iPhone 5 in December. It has just recently, within a month, began to show problems with the power button. Initially, the right side of the power button had stopped working, and I had to push down on the left side in order to sleep/wake or power off/on. Yesterday, the entire power button became inoperable. I now have resorted to Assistive Touch to sleep/wake and power on/off my iPhone 5. If I bring this phone to my local Genius Bar, will they replace my phone? If they will replace my phone, I was wondering about something. Could I ask for a 32GB iPhone 5? Would they allow that? I would be willing to pay money for it.

This is a common issue with iPhone 4/5. They will replace your phone if its a "hardware" issue. If you are not in your warranty time frame anymore, they charge you $20 just to talk to them basically. They will not upgrade your phone to a 32 GB either. If you have insurance on your phone, its about $100 to replace it. Since you said you got it in December, you should be in your warranty time frame. I would go quickly. They try to get out of replacing their products.

Power button issue Mac Pro 2.66

Mac Pro 2.66 is connected to a power strip I now notice that I do not have to press the power button to boot this Mac up. To boot it I need to just turn the power strip on WITHOUT pressing the power button and it boots right up. Only occasionally when I turn on the power strip its connected to I have to boot using the power button.
My question is what should I do here?
Isn't the power button part of the power supply?
If so can I repair the button or do I need a new power supply?
Anyone?

Your Mac may "restart automatically after power fail" if that parameter is set in:

Power Button issues A1226 Late 2007 Macbook Pro

I know this sounds stupid but usually when I touch the power button a window pops up and asks me if I want to restart, shut down, or sleep. After I did the OSX update to Mavericks I have noticed when I hit the button the screen just goes black, as if it's automatically going to sleep. This is weird. Is this a legit change in the OS or is this a problem? If it is a problem, can it be fixed?

I have noticed this too. I have noticed the MBP is more glithy since the update and have to restart more often. Programs freeze, runs slower, Movies on in iTunes and on the web(netfix) stutter. Hopefully more poeple comment and Apple takes notice.

23" ACD Power Button Issue / Display Options Missing

One time my dual 2ghz power mac froze upon coming out of sleep mode so i held the power button to power down the computer, but before i did that, i touched the power button on the side of the monitor, hoping to somehow bring up the password prompt out of sleep mode but the screen stayed black and the cursor / ball would just spin for minutes.
I used to turn on / off my computer and the display would automatically go on / off with it, but now i have to manually power up and down the monitor. And in the system preferences, there is no longer the options section where i can choose what the power button on the monitor does.
Can anyone help out with why this is happening? A million thanks in advance.

Your computer no longer has USB connection to the monitor. Do the USB ports on the back of the monitor still work? Sometimes unplugging everything, including the power cord, from the monitor for a while will fix it temporarily.
