Power Button- slow? - Nexus One Q&A, Help & Troubleshooting

i noticed recently that if i press the power button, it sometimes takes a really long time to turn the screen on. i know the hardware works because the backlight in the soft buttons turns on immediately, but the screen remains black for up to 10 seconds. this happens rarely. however, im fairly sure it isnt a software problem because ive wiped completely and installed a fresh rom and the problem seems to persist. perhaps i just recently noticed, and the problem was always there? does anyone else have this problem?

three threads above yours.

could be a hardware issue.

Mine does this every few days.. I am still on the stock 2.1 rom.

Mine also does this, I only noticed it after flashing Cyanogenmod 5.0.6. so I thought it might have been a bug. I also assumed it was a bug because the phone seems to act strangely when you are touching the screen and try to hit the power button.
Hopefully this isn't a hardware issue, I've had the phone since release.
Is anyone else experiencing similar issues?

It happens to me as well, but very infrequently. Maybe every few days... so it doesn't bother me enough to worry about it.
I'm on stock ROM btw.

I am leaning towards thinking this may be software related. A few minutes ago I was at the lock screen and tried about 50 times (yes I waited long enough after each press) and simply could not get the screen to turn off. I then tried long pressing the power button and, sure enough, each time it would bring up the shutdown menu (yes, over the lock screen). Must be a bug right?

Hmm, my problem's slightly different. Around half of the time, I have to press the power button twice to turn the screen on. Sometimes, pressing it the first time doesn't turn the screen on, had to press the power button firmly again.
This started only recently. On stock n1 and bought it during feb.

that means that your power button is dying, like many others' (including mine)
this is the first time, it takes 2 clicks to work....than it will increase.
Expect a repair soon...

Well i am having the issue other way around. i am not been able to put my phone in stand by mode by clicking on it and it is do a hard press then i get options to shut off the phone
any suggestions what might be causing it ?

I'm happy I haven't received this problem yet

I am having the same issue and i wonder if you were able to find the cause for it. I have the same rom as you do on your phone

I have a similar problem. When I unplug the N1 from the charger, the screen comes on showing the lock screen, and I can't get it to turn off. If I unlock the phone, however, then the power button works normally. I don't think it was doing this until recently (I bought it in January the first day it was offered and am running the stock update1 ROM).

So here is my theory if the power button is a problem then it needs to act up both ways and not only one way. right now i can put the phone in sleep mode but i can wake it up. i will post the issues on the development forum and might be able to find an asnswer to it

So seems like the issues is because of Cyanogenmod 5.0.6 because since i have flashed another rom it is working just fine. i will be doing some more testing before i can be certain

Another problem I am experiencing is when I long press the power button, it pulls up the phone options menu but also turns off the screen. It's extremely frustrating as it does this quite frequently; right after I power on the screen again and unlock the device it works properly every time - so much so that I am convinced this is a software issue.
I am now running froyo, rooted with Cyan's minor root patch. I can also say for sure I experienced the same problem on CM 5.0.6, but it definitely occurred less frequently.
Am I alone here?

I just started having this problem after upgrading to 2.2.

I have this every so often. But sometimes wonder if it is flyscreen doing it

You guys should all just be running the app no lock to take the power autumn out of the equation.

Ahhhhh! I just need trackball wakeup!

I have a similar issue where my screen will turn on but will be unresponsive. When i turn it on and off, the backlight jut comes and goes. If it times out it won't turn back on for a bit(the backlight will come on still).
I just wiped my phone, hoping that'll fix it since it only started happening on a regular basis since I updated to Froyo

Nexus one not waking

okay so when my n1 is in sleep, it takes like 3 tries to wake it up. The first time I press the unlock button the unlock screen comes and then goes back to sleep instantly. The second time the lights for the back menu home and search light up and that's it. the third time it works. I'm on froyo. anyone else with this problem?
I have a similar issue.
Sometimes just the capacitive buttons light up and not the screen. I have to make 2 or 3 tries to get it to turn on. Its rare, but its there. It only happened on 2.2.
ok good, me too!
was just looking for this topic.
mine doesnt always turn anything on at all. sometimes the light go on, others nothing. Also trying to turn off the phone is hard as it sleeps straight away with out opening up the power menu.
I have a stock N1, which recently updated to Froyo, with the same problem.
any ideas would be great!
cheers,

Also happens on CM 5.0.7.1.
i think it may be a hardware button issue.
I have tried turning mine off (had to pull the battery out) and then to turn it on.
It should turn on readily as it has nothing to do with the OS at that point.
any ideas?
No HW button issue described. HW button works - if it didn't, lights wouldn't go on. It's a wrong reaction on the button, at least that's what OP describes (and me too).
Your N1's power button is dying, it's a known HARDWARE issue. I experienced all of that what you may think a software bug, nut dear friends, prepare to meet HTC or Google for warranty. My N1's power button is dead, I couldn't swap for a new one because I bought it in my country where no official distributor for N1 yet. Sad!
ps: you may try to search for "N1 power button" and see there are more and more reports about this problem.
I've read more than one or two threads on power button issues, and I know what I'm talking about. My power button DOES power up the phone when the battery is taken off the first shot, it DOES wake the phone from standby, it DOES register long presses - there was even one time when a second press was long, and suddenly the screen woke up with power menu, while the first press left it dark with touch button light going on.
Doesn't look even a bit like HW to me. HW would leave the phone dead, non-responsive to touches, or create a loose touch which would translate into several touches - none of those would EVER turn into a phone being on with screen off, and suddenly snapping back to screen on when the SCREEN is touched several times.
Could be your cpu was too busy to accept any inputs.
I have a thread about it here:
http://forum.xda-developers.com/showthread.php?t=692874
Take your time! As for me, I'm using my N1 for 3 months now for the power button to completely dead with everyday use (I didn't use any app to trackball-wake).
As I said, all the things you are yelling I have been through. And I, too, thought it was software problem.
I tried both MCR and Cya with no hope.
Good luck!
ps: One of my friend just told me about his N1's power button issue right after hearing me telling about mine.
This sucks
anyone know where i can buy a new button??
Corrupt SD Card
I had the same issue. I'd press the power button, the bottom four buttons would light up but no screen wake. Only way to get out of it was to pull the battery. It would happen maybe 30-40% of the time. (Nexus One Froyo FRF72)
I think it was due to a corrupt MicroSD card. I recently installed a 32gb card and put some music on it using songbird and possibly didn't safely remove. That's when I started getting issues. Removed the SD card completely and it worked fine. Changed back to the old card and no issues. Then formatted the 32gb and tried again, worked fine. Then I tried to transfer more music, there was an error and I got the same problem. (Cheap ebay card from Hong Kong, that'll teach me).
Anyway, I'd be interested to know if that solved anyone else's problem, because all I see on forums are that it's a faulty power button, but that didn't seem to be the case in my situation.
Cheers,
Dylan
-Witty esoteric statement about science/technology.
Mine is doing kinda the same weird thing but a little different.
When I push the power button the screen comes on but is unresponsive to touch. If I press the power button again the screen dims and then turns off, the home keys light up and then the trackball glows white. The phone then does not respond to the power button for around 10 secs and repeats this behavior 4 or 5 times until it actually starts working correctly and I can swipe my finger to get to the home screen.
It usually does this after being inactive for a period of time, like after sitting overnight.

i have almost the same issue, although mine happened twice when i was on EPE54B but it's been far more common on FRF91
the only difference is my power will continue to turn the back light on and off no matter if the screen has already timed out or not

I have exactly the same issue. Over in the general forum, there's another thread on this issue. Many, myself included, are reporting that this problem started after the FRF91 update. Can you confirm?

Read again carefully. Are you sure your hardware problem was identical to what the OP described? I've noticed a lot of people with obvious hardware problems (i.e., the power button is completely unresponsive) posting on threads like this when they actually have a different problem. It's very confusing.

I had this problem when I first flashed CM6 yesterday. Even after wiping and reflashing it was the same. Only way to get out of the black screen was to do a soft reset, power + vol down + trackball. I finally found out that my SD card malfunctioned and was corrupt. I tried reformatting the sd card in an microsd card reader but windows said it could not be reformatted. I finally switched back to another microsd card that was working, wipe and reflashed cm6 and the problem went away. Try backing up all the data on your microsd onto your computer then reformat it and wipe then reflash to see if it works
Edit: ughhhh it just happened again, but not as bad as before, turns back on after second try... maybe i didnt press the trackball hard enough

Screen won't timeout

Very odd...
My screen won't timeout anymore, unless I manually press the power button. It doesn't matter whether the phone is plugged in or not, and it isn't dependent on the screen I am on either. The screen just stays on forever.
Is there a way I can see if a certain program is preventing the screen from sleeping? Has anyone encountered this type of thing before?
Thanks!

Did you check the screen time out settings, maybe you got it at 30mins ?
Yeah, it's set to 30 seconds. It must be some program that tells my phone not to sleep?
Even more odd...
It fixed itself!
Rebooting the phone for the last couple days had no effect on the timeout issue I was having, but doing it this afternoon somehow resolved the issue.
Add this to the list of idiosyncrasies that my SGS has.
I'm having this annoying problem with my SGS (JPY) at the moment. Sometimes it'll go to sleep and turn off the screen by itself, but 9 times out of 10 I have to manually turn it off with the power button.
Has anyone else experienced this with JPY? I'm reluctant to wipe and start again, but it's really starting to piss me off now...
might be an old topic, but i am experiencing this right now
i just installed gingerreal guerilla version yesterday and it works fine
however when i connected my phone to usb for charging this morning, it wont turn off the screen unless i do it manually by pressing the power button
weird thing is as far as i remember there's a setting on USB debug mode to turn off the screen when connected to usb. i think it might be related to the rom or is it always like that on gingerbread? i assume that is the root cause,
although i couldn't post the issue directly on the gingerreal thread due to minimum post count.

[Q] Nexus One CM7 power button problem

I have an AT&T unlocked Nexus One that I recently flashed to CM-7.0.3-N1 . I have had a problem unlocking the device with the power button both when I was running stock Gingerbread and now that I have installed CM7.
When the screen is off and my N1 is in standby, I push the power button and the screen turns on and then back off almost immediately. Sometimes there is a half second delay before the screen turns on and then off. This usually goes on 2 or 3 times until the screen will stay on and I can unlock my phone.
Has anyone seen or heard of this problem, and maybe knows of a fix? It could be hardware related, but the button definitely sends a signal to the phone and it works fine to shutdown or turn on the device from completely off. Thanks.
ummm the power button on the nexus one has an incredibly high failure rate, all over the forum here. its a design defect from the factory. that's why it has always been recommended to root the device immediately, and use trackball wake, so you avoid using the power button as much as possible. you have to send the device to HTC for repair, that's your only option...
Thanks for the information. I will have to look into repairs.
You are already running a rooted rom with track all wake. Use it. To reboot the the phone use quickboot. At this stage you really don't need the power button on your phone.

This is a problem with CM7. Most advise turning off the screen off animation if it becomes a big problem for you. Make sure you are using the newest nightly and hope for a fix. I don't know if the RC's have this problem, but I would bet it appears on the 7.0.3 release.
At first glance that seems to have helped. Thanks for the advice!
No problem.
Also you can use widget locker to lock the screen then the trackball to wake, with that and quickboot I don't even touch my power button anymore. Although your problem doesn't sound like a broken power button so in your position I would switch ROMs and see what happens.

I'm experiencing exactly this too on the latest RC. It doesn't seem to be complete button failure but it's acting like I've pressed it twice sometimes. Disabling the screen-on animation does seem to prevent it from popping back on. But it still sometimes goes on-then-off when I wake it with the power button. So now I'm using trackball wake too.
As others have mentioned, this does not sound like a powerbutton issue, because the powerbutton still turns on the screen. The problem is that the screen turns off immediately after it turns on.
When you flashed 7.0.3, did you come from a previous CM verison? From stock? My first suggestion would probably be to wipe the /system partition (in CWM, it is under mounts and storage -- with Amon_RA, you need to find a flashable zip to do it) and reinstall CM and gapps. This will not cause any data loss. Sometimes, if you install a new ROM over an old one, the upgrade script in CM can get confused and carry over files that aren't supposed to be carried over. The system wipe fixes that.
I've been using this RC since it came out in late June. Only this week did it start flipping out on me.

It still can't hurt anything to do a system wipe, just in case something got screwed up (these things can be so temperamental at times). And, like I said, you won't lose any of your data.

I'm currently using S2E for apps2ext and some data2ext. How would a system wipe and reinstall interact with that? I'm a bit nervous on that front.
A system wipe shouldn't change any of that. It is one benefit of using S2E as it is a standard app that is stored in the /data partition without any changes to the /system partition.
Anyway, to be safe, it is a good idea to do a nandroid backup anytime you are doing something that involves the majority of the features in recovery.
It's a hardware problem for me. Failed completely as of today.

CM7 7.1.0
My power button seems to be in the process of completely failing. The new CM7 update to 7.1.0 has made it possible for me to lock the screen without using the power button using the "Notification power widget" -> "Go to sleep". Now the only times I have to use the power button are to shut the phone down or wake it up, which seems to be easier when the phone is plugged in to a wall charger. Are there any simple apps for shutting the phone down and maybe waking it up at a set time?
The only reliable trick I found to turn it back on was to plug into the wall and take the battery out/in a few times till it vibrated.
I ended up getting a replacement phone and then I sent the Nexus to HTC. They quoted a $55 repair cost off warranty which my credit card insurance would've covered, but when I asked for an invoice they offered to just waive the charges. Finally over a month later it came back fixed.
The app Easy Reboot can shut the phone down.
Sent from my Nook Color!
I also use an app called Lock Screen, which just locks the screen. I have it stored in my dock, because I don't like the space being used in the notification widget.
CM7 has an option for one of the items in the notification tray widget to be a lock screen button.

THANK YOU!!!! This has been driving me crazy. Turning off the screen-off animations did nothing, but turning off the screen-on animation seems to have fixed the issue. My power button is toast (my new power button ribbon cable just arrived... time for surgery), and I've been using the trackball to wake my phone. Before the power button died, it did the same thing. I'm using CM7.2. I installed it after rooting and went straight to cm7.2 from stock, so obviously the cyanogemnod crew haven't fixed the issue since 7.0.3 when this thread started.

[Q] phone will not power off or on properly. Shut down menu pops up constantly

I have searched this exact title and came up with 10 pages and I never saw anyone else with this problem. Surely I cannot be the only one.
After the Gingerbread upgrade I was getting the tethering message/force close, during that time my phone started to randomly shut off ( settle down Beavis, this isn't the same question thats been asked a thousand times ) and reboot. I lived with the tethering message problem for as long as I could but my phone became more ignorant day by day. I finally found a fix for the tethering issue and haven't had a return problem with that but now my phone either stays in standby mode ( dark screen ) and refuses to respond to the hard button to wake it up OR once on it refuses to go into standby mode and stays on until I pop the battery or I go into settings and time the screen out in 15 seconds ( often times this doesn't shut it down either ). Sometimes I can get it to come on by multiple pressing the power button ( this can't be healthy ) and the lock screen will flash momentarily just long enough for me to unlock the screen. Other times it will go to the lock screen while I'm in the middle of something.
Every day at some point while it's on and I'm using it, the power button option screen pops up ( silent mode, flight mode, power off ). When I'm done with a call I try to go into standby and it just sets there...ON.
The thought has crossed my mind that the button doesn't work or has a short but I really think it's something else ( I hope ). Can somebody help me? I am not very techie although I have updated the phone three times myself. It is unrooted and 2.3.5
Thank you in advance
I would go with the power button. It's a known issue on captivate.

I stopped by the AT&T store the other day to check on insurance (ends up I didn't have it) and told them about my button not working properly and how the Captivate was notorious for this problem and they all said "We've never heard that". So the gadget gal is in there so she offers to take it apart and check it. She claims there isn't anything wrong with it and that it has the same amount of spring as the volume buttons. She then noticed that when she put the battery back in the phone came on automatically, I said it's not supposed to do that and she agreed but fortunate for me since I cannot turn it on. She then says I'm eligible for an upgrade and try's to sell me a new phone. I don't want a new contract.
So should I try and buy a new button and change it or could it be something else? Thank you in advance.
Are you using a case for your phone by any chance? If yes, is it too tight? Maybe the power button gets stuck because of that sometimes? Just a long shot! You stated that power menu pops up once in awhile when you're using it, is it possible that the way you grip the phone causes that? (Just trying to help and not trying to offend you btw.)
You might want to try flashing UCKK4 with bootloader(use it from the one click master collection of stock rom's) just to make sure that there is no issue with the firmware. It is not likely to fix your problem but it's good to have a clean start. At least that's what I would do to begin with.
Since you're willing to change the power button, why not do an experiment? Remove the power button and see if there is any change? If it works fine then it's the power button that's faulty else it's a hardware problem.

[Q] Wierd problem when turning screen off and on

Hey guys, im having a bit of a problem. My phone is shuting off on itself.
Everytime i turn it on, it boots up no problem, but when i hit the power button to turn the screen off, when i want to turn the screen on again by pressing the power button, the screen just goes deep blue, and turns off.
I haven't change anything on it for quite a few months now, so i'm not sure why this is happening. Im on Viper 3.5 i think or 3.7, using faux123 kernel, dont remember which version, but an old one with which i never had any troubles... rooted, s-on
Any ideas?
Thanks!

PD: Logcat in the .rar file...was too big for .txt
Really?? No one??
Well, just for further info... my phone appeared to fix itself, since it stopped doing that weird thing for a couple of days, but now is back... nothing ever changed, no new apps, or settings or anything...
Any ideas welcome
Edit: Attaching new logcats...

I think your power button is broken (or you may have a related hardware issue). Nothing but a root app can reboot the phone, and I've never seen that happen by accident.

Yeah, i thought about it being hardware but something is off... i mean, if it where the power button, then i shouldnt be able to turn it on easily, or it wouldnt turn off the screen properly, nor would it just start working alright for a couple of days... plus, it didnt recieve any hits or anything during, before or after the problem.
I also thought it could be the screen, but when its on, it works perfectly, as on the first day...
But yeah, I'm not taking hardware problem out of the table...just seems unlikely to me...
Thanks for your answer!
Coldsun15
Edit: also, I just found out it doesnt actually restart...screen just turns dark blue, then it powers the screen off and it wont turn on when pressing power... but i know its on, because i can still hear notification sounds of incoming messages...
Edit2: Just tried same but instead of using power button, i used logo2sleep and home2wake kernel options, and did the on/off with them, and same result...dark blue screen then off and not turning on... so it cant be power button
