Okay so I have searched the world wide web over and I cannot find a solution to this problem. I rooted and flashed cm7 to my Captivate. I did not make any backup before doing this as I just jumped right in without proper research beforehand. Everything went smooth until my power button randomly stopped working. I disassembled and cleaned the power button multiple times with CRC Electronic Cleaner to no avail and it did nothing. Then I attempted using Odin One Click only to realize I somehow no longer have access to download mode no matter what I do. Now my power down menu (menu that appears when power button is held) pops up randomly without the button being touched. All that to say I would like to get my phone back to stock out of the box condition and see if that would solve all my problems but I can't figure out a way to do that without download mode.....??? Please help :crying:
Make or buy a jig, that'll fix your download mode issue then just flash with odin.
Also your power button issue won't be fixed by going back to stock. The only true fix is to get a replacement button. However it's not very easy because it's soldered onto the board.

I remember seeing a thread on here about mapping the power button to a volume button if I'm not mistaken, it doesn't really "fix" the issue so much as work around it but it's still something to try to the unskilled electrical person

Well I cleaned my cousin's nonfunctional power button and got it back in working order so I thought maybe the rom could be my problem sonce cleaning didn't work but maybe it is just permanently damaged.

Also there is actually an option on cm7 to use the volume rocker to wake the device which I am using I would just like restore use of my power button.
Check out mobiletechvideos.com for the repair. Very well known and reputable around these xda forums...:thumbup:

I think this is a hardware issue and not a rom issue, I've never heard of a supported ROM causing the power button to not work. Have you tried a key test in recovery? If it detects the button then yes it's a rom issue if not then it's hardware.
Mobiletechvideos.com is very good, never used personally but I've seen a lot of people take their cappys to them to fix USB ports etc.

I don't understand the information produced when I do the key test. I get "Key: 217". Another try produced "Key: 217" "Key:158" I don't understand the codes and I can't seem to find them online.
When you press the power key, it should spit out a number. The number isn't important so much as the fact that it RECOGNIZES that the button was pressed. If that's the case I don't think it's hardware and rather software.

It could be but again it could still be a hardware issue. In my experience with the captivate my power button started out sporadically popping up the power menu. Then it quit working all together. Then one day it just started working again. And still to this day it will occasionally act up again. When it does I haven't changed anything to do with my software setup.

True, but if it always works during the keytest and never once actually booted into the rom, then it would be software. My iPhone 3GS used to have a broken sleep button, so I just ended up remapping it to the volume keys and that was fine for me. Less work and never really found it a big deal especially with older devices.

Feel free to add this to the FAQ, I'm only making a thread of this because I know alot of people have found themselves unable to enter the bootloader using the Down Vol + Power Button combo that is normally supposed to work.
For some odd reason, it seems as if the volume button in some cases is swapped in hardware functions as it relates to the use of the phone when no software is present to run it.
Hence, if your down volume button doesn't work, try using the camera button + power button to enter bootloader mode instead.
Even if you've just Task 29'ed your device only to find that you can't enter bootloader mode normally, that method should work.

I'll be darned, it does work! Thanks Poet' !!!
Otherwise, I had bad volume button issues (stopped working, ROM independent), that I solved by shoving the mini-usb power plug into the mini-usb slot really really hard for 20 seconds or so and wiggling it a bit while pressing against on the volume key on the other side.
I know it sounds strange, but it really worked. My keyboard issues also stopped after that. Theories?
WOW! My volume button is broken, and couldn't flash ROMs from microSD (didnt bother me tooo much), but it works again This is a god send! Thanks!

Thanks for the tip, but its physically phucked! Slight crack near the volume button, but only the volume button doesent work, sometimes it does work if pressure is applied to the case near the crack, but rarely Not too bad though, i can live with it, after all, we can change volume with the 6.5.X top bar as its not fidly, or even in 6.5 by disabling HTC notifications (which i hate anyway)
I did try ramming the mini usb power plug into it, different pressure while pushing it, moving it while it was inside etc, no such luck and i am a brute with this phone. I love how it can take a drop/punch/scratch. Built solid
a silly volume button doesent really decrease my fuctionality, or doesent do much to stop me changing volume! lol cant complain.

Hi guys,
is there any possible i ask (maybe) the same problem?
maybe i had the same problem here. it wont enter to the bootloader. my phone just won't turn on, i already try to use the power button and volume button (not working), try to use power button + Cam button (won't work either). btw when i charge my X1, the illuminations light didn't show up, when i try to charge w/o the battery only red light on the power button, but once i put the battery again the lights turn off. is there any possible that my phone totally dead? thanks guys, appreciate for your help.
where were you before i paid 125$ .
i had this problem weeks ago, i tried many things, posted many threads here in xda but with no use, i sent my x1 to the shop to be fixed, i paid 125$ to be fixed but the couldnt fix my volume key, do you imagine!!!!
they just booted my x1, installed the original window and sent it back to me with a heavy reciept

I have read many threads about the issues that the Nexus One has with the power button. I feel that my situation is a little different, so I wanted some opinions on this. My power button is completely unresponsive. I can't use it to turn the phone on, wake or lock my screen when the phone is on, etc. My phone has an unlocked bootloader and is rooted. I am currently using the track ball to wake my phone, so I'm not having any real issues with day to day operations of my phone. I was completely convinced this was a hardware issue (and still am), but I wanted to be 100% sure it was a hardware issue before contacting HTC. I downloaded Quick Boot from the android market which allows you to reboot your phone, boot your phone into your Bootloader, and boot your phone into Recovery. I decided to boot my phone into Bootloader mode to see if the power button would work there. The power button didn't work in the Bootloader, but neither did the volume button (prior to this test, I had no issues with the volume rocker at all). I pulled the battery and let the phone boot up to check and make sure the volume button was still working when the phone was running. Once the phone was booted up, I had no issues with the volume controls. My question is why would the volume rocker not work in the Bootloader? Also, could the issue that prevents the volume rocker from working in the Bootloader be preventing the power switch from working while the phone is booted up? If there is a chance that it's a software issue, how would I test/correct the issue? Thanks your help.
Most people I have seen complain about that problem, send the phone back for a free repair because it's a hardware problem.
The best way to test it is to flash a stock rom.
Thank you, I will try reflashing the FRF91 stock firmware and see what happens. Thanks.
Definatly sounds like the power button is broken. I had one like that. Send it back for a repair/replacement.
I've checked my immediate suspicion, and it turned out to be correct - so I'm posting the result:
Your power button is actually stuck in "ON" position (pressed).
Anyone can test it, press the power button to wake up the screen, keep it pressed, every operation is allowed in the system and volume buttons work. But when you reboot and try the same in bootloader, having power button ON disables the rest of the buttons.
My screen doesn't wake when I press the power button. Any other ways to check if it's stuck in the "ON" position?
It's 100% determined by your description. The only other check would be running any kind of SW that shows the current key states, and I'm not aware of any such SW.
I've posted the checking procedure for people with working power buttons, so they can verify the findings.
Any way to fix the issue?
If you're technically inclined and can't use warranty, I suppose that getting to the power button and repairing/replacing it wouldn't be very difficult. But no other way I can think of.
has anyone tried to repair this?

A DIY can not be too difficult and you may be best to search YouTube. It can not be too terribly difficult as long as you can open it up and remove any connecting ribbons (I've had to replace my girlfriends iPhone digitizer due to phone falling out of back pocket onto concrete from three+ feet up). As long as you can open it, you're fine. Just going to need to re-seat the button. Good luck!
Greetings,
I had the same power button issue. I was able to wake my phone using the usb cable whenever the screen timed out but otherwise the phone worked 100% of the time in all ways. I got an RMA and label and shot the phone to them in an anti-static wrap with 4 inches of bubble wrap on all sides and foam padding on top of that. The phone was in perfect condition. Well to cut to the chase. I got a quote of 196.00 because they said there was water damage!? I treated that phone better than I treat my own body! There was no water damage when I sent it in. So one of their folks send me images of a phone that has a broken screen, water damage in the base usb port and no inscription. Interestingly all of the angles avoided showing the ein or s/n. My phone has a laser etched inscription with my name and a couple of bible verses. So what am I supposed to do here? Pay another 196 for an 800 dollar phone that had nothing wrong but a power switch? I am a T-Mobile customer and an Android developer in good standing. What the heck!? Can anyone give me a suggestion on how to get this squared away? My only other option is to send them $28 to get the phone back with the same power button issue. It's even under warranty until Jan 28th.

Does anyone know if htc india supports the nexus one for after sales service
The physical power button on my Samsung Captivate seems further suck into my phone than normal. When I press it, i hear a click but either nothing happens or my phone brings up the menu for holding the power button.
I am 95% sure this is not a software issue because i flashed back to stock using Odin and the problem remained.
Is there a hardware solution to this that is better than tweezers (which have so far been not successful) or is there even a software solution where i could re-macro my keys?
You could probably can get a replacement from samsung
I have a similar issue. My power button also sits further down in the phone than usual and is sometimes non-responsive. It mostly works but does tend to bring up the shutdown menu sometimes instead of putting the phone to sleep. I'm going to take it to the att store Monday and see about getting it replaced under warranty.

Hi guys! I am buying a Nexus One. I just read about the power button problem. I wanted to know if there is any way that I could take care of my power button so that it does not break. I also wanted to know if there was a possible way of remapping the power button, for example the power button dies out on me, I could use the Volume up button to power on my device (cold boot).
Well that depends if you're running stock ROM or rooting and installing a custom ROM. I'm gonna assume you're gonna root and say to get a ROM with trackball root. This way you can unlock with the trackball and save your power button. You can also get a one of many apps that lets you lock the phone from a homescreen widget.
If you're not planning on rooting you could install GoLocker which would let you unlock with the volume rocker. Think the locking widgets should still work too.
Hope that helps.
I read somewhere that pressing the power button from the side closest to the headphone jack would also prevent damage to it. Is this true? I haven't really gotten my N1 yet so it's kind of hard to visualize how the power button works on it.
Yeah like addam360 stated, I use CM7 ROM with trackball unlock/trackball wake.
Barely use my power button. There's also app like Quickboot which let me reboot or reboot to recovery without having to use the button.
CM7 ROM also have an option to shut down via widget.
As for which side to push I really couldn't tell you.

So that's where I got the info of pressing closest to the audio jack. Thanks very much for the info. So what if I were to place a thin piece of paper between the trace and the plastic power button head so that it does not press down on the trace? Do you think this will help preserve the trace?
I have had my nexus one for a year and 8 months, I haven't payed attention to where I click the button and its still working properly.

If anything, that would probably push the trace down more every time you pressed the power button. If you really want to try a fix, see about grinding down the part of the power button above the trace - that way you won't accidentally press it on the wrong side.
I'm using an EVO 3d so I don't have insight for the N1 but I do know moving parts break. It's one reason I think slideout keyboards are retarded. But most aosp roms allow trackball wake. Me personally I think my volume down is going out. Scrolling in recovery to my download folder is like 16 presses lol. Lucky for me I can get a new back cover and be back to new.

Okay so my power button just randomly stopped working after some random time. it doesnt work ANYWHERE. to lock my screen, to unlcok my screen, in recovery mode i cant press anything cuase it doesnt WORK. i no its a hardware issue becuase of this. i did google this but found nothing. what can i do to fix it.
i tried a battery pull and putting it back and going to recovery to factory reset but as soon as i put my battery in my phone starts up. i can enter recovery but the power button doesnt work so i cant press anything.
my warranty is over by a long shot ( had it since it released) so cant return it.
any help would be appreciated. all i need is a way to turn my phone on and off nothing about the recovery and stuff. but if you do find someting for it that would be even more amazing.
and has this happened to anyone else, just wondering is all if this is common or rare.
thnx in advance.
it has happened to many captivates. search 'captivate power button' on xda.
What ROM are you running on your phone?
Answer to that question has a lot to do with your next steps for software workaround.
One approach; you could read up on ways to clean the power button and see if that works. Or send it off to mobiletechvideos.com and he will fix it for a reasonable fee.

i am running Aocp 5 android 4.2.1
hve been running it for a few weeks now and no problem till now
Okay, start by seeing if you can clean the power button, that may fix it for now. Again, search 'captivate power button' to find some threads about ways to clean it.
With the ROM you are running, I believe you have a version of CWM that allows to use the Cappy's dedicated menu keys, menu, home, back and search, to navigate and select recovery items.
Assuming your power key is stuck on, remove the battery, hold the up and down volume buttons and reinsert the battery to get into recovery. This will allow you to test keys, wipe, and any other function in CWM.
With the phone on and fully booted into JB, go find volume rocker wake in the system setting options and make sure it is active. Hitting the up/down key will wake the screen when it sleeps. Add the sleep/lock toggle to your notification bar menu and you have a way to instantly lock the screen without the power key.
If you still have a bad power button stuck in on position, then you will need to take out the battery to turn it off.
Hope this helps.

This is happening because your power button is stuck in the on position. Did you try to clean it as suggested earlier.
BWolf56, I'm not aware of an app or ROM that completely prevents power up on insertion of battery when the power button is stuck on. If there is such an app, I'd like to hear about it. I think maybe the power switch goes to the broadcom power management chip, so I don't understand how the app could work unless the phone never came on at all. SOD symptoms would be the result.

I had a very similar problem with my Epic 4G Touch (Sprint S2) - my phone would randomly reboot, and it kept getting worse and worse. Thought it was the ROM, the overclock, etc. I flashed back to (almost) stock, went back to original clock speeds. Eventually, I noticed that even brushing past the power button would wake the screen, and about 10 seconds later the phone would reboot.
Long story short, I bought a replacement power switch, soldered it in place, and have had zero problems since!
Several eBay sellers offer the switch you'll need.
(They don't include the skills needed to solder it in place. It's a tiny switch - about 4mm x 2mm x 1.5mm, and you'll need a good quality fine-tipped soldering iron and a steady hand. Do you have a friend who's good at soldering?)
