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,

-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.

This sounds VERY promising -- thank you britoso!
PS: Are you guys getting the unresponsive unlock slider like britoso describes?

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

[Q] Help N1 won't Power on

Hey Guys I really need your help my N1 won't power on for some reason. I really need to get some things off the phone from certain software that I had in case I have to have it repaired or sent away. I'll try to be brief what happened I was exercising with my phone inside a protective case that covers the whole phone and I went to change the next song while listening to music and when i went to push the power button the screen remained black the whole time and I couldn't see anything at all the screen was black the whole time after numerous attempts at pushing the power button. So I held down the power button to try and reboot it and then the music stopped, so then I hit the power button again to turn it on and it hasn't turned on since yesterday. I even took the battery out and let it chill for a min and still doesn't work. when I plug it in to the charger the orange/green light comes on and as well with the USB connection too, but still can get it to power on.
Anyone have any Idea what it could be? I am assuming it's the power button but I am not for sure. Is there anyway to turn it on again in case i need to recover any files, etc. the reason i want to get it to work is that I don't want to have to go through the hassle of sending it away to be repaired if there is some way I can do it myself. I am trying to avoid sending it away with my carrier and I really need to access certain files on the phone if all else fails. If anyone has any ideas I'd appreciate it thnx to anyone.

If it's a power button failure, you can put the phone on charge, then remove and reinsert the battery... keep trying, it will turn on eventually...

it worked the first time I did it thank you so much well just in case it ever happens again how can I back up some things on my apps for example I have notes on AK notepad how would I back those up? and if I wanted to move some software to my sd card that doesn't allow it?
Hey thanks again you are a life saver!!!!!!!!

oh darn the X came up when I powered it up but still nothing just a black screen I got all excited for nothing

i got after 5 or so times of taking the battery out thnx again is there a way or software to make the N1 awake or power off with the trackball without rooting it since the power switch is buggy now?

Titanium Backup will backup apps and data to SD card.
Widget Locker has an option for trackball wake.
LockEnabler will let you turn screen off/sleep.
Quick Boot will let you reboot, boot into recovery etc. Be careful booting into recovery or boot loader, because power button is used to navigate (you have to use adb).

thnx again is there anyway to restart/reboot the phone if it is not rooted via trackball or another button?

Reboot is possible with Quick Boot (as noted above), but if you ever turn off then the battery toggle is your only option...

[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.

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.

Recent apps disappearing, Auto reboot, & Accidental power button presses

I have found that it is too easy to accidently press the power button. Mostly, the accidental presses just cause the device to turn off or on. However I am guessing that it is also causing my N7 to reboot without my knowing it. I was occasionally finding that I had No Recent Apps listed over the course of a week. Then yesterday it was has happening a little too much, so I did a little investigating and noticed my battery app was showing that my N7 was recently rebooted. However, I hadn't rebooted in days, nor seen a reboot. So since last night, I've been careful with how I set the device down; making sure the power button doesn't touch or rest against anything, and so far no reboots, or stuff disappearing. Anyone else finding their recents app list is being cleared out, or notice automatic rebooting?

I seriously doubt that the power button is sensitive enough for it to cause reboots, sounds like you have a software issue. it also sounds like it may be quick rebooting, not completely

I'm still open to this being a software issue since I have never witnessed a spontaneous reboot. Some sort of software problem was what I thought at first, but at the moment I'm leaning toward the power button being accidentally pressed. The argument against this is that the button is fairly stiff, but not so stiff that I'm not able to rule it out just yet. I did do actual manual reboot myself last night (ie power down and power up); that could also explain why the problem has not shown itself again. Luckily, I have no other problems whatsoever, and this is only a minor issue so far.

Dead within 8 hours of use (dead dead. not battery dead)

ok so i've been using it a bit but my battery was 70% last i checked. was playing around with throw and just opened youtube and the screen flickered a bit (black lines) then decided to go black completely.
nothing i do will make the screen do anything.
holding the power button for ages (usually the way to turn off/reboot a phone) doesnt do anything. the backlight is on as i can see that. but nothing is on the screen.
anyone got any ideas on how to force a shutdown/reboot on these?

IIRC the Xperia Z1 has a hard reset button under the sim flap, it's a small red button, give it a shot.

remove sim card and sd card and try again, if it's still not responding do an update repair using SUS or PCC
BTW there is a known fault with the XZU and it could also be on the Z1 as they use similar Firmware, what people have found is that the phone will start up eventually and then they go into the display setting and untick the auto backlight option and that fixes it

I also reboot my Z1in this way when it blackout.

It recognises that I've out a cable in as I played with the smart connect setting. When it is off completely I get a red light (presumably meaning its charging ) but not in android
Any ideas?

Got it charging again by pushing the red button near sim slot for a couple seconds.
Just had another issue with SD card not being recognised after I removed another (/safely) had to reboot again using power plus vol up as it stuck on the shutdown logo when I tried to power down'...
Wow I can't believe the amount of issues I've ran into within 24hours of having this thing. I really don't know what to do...return it because it sounds like a faulty device (but all the issues are seemingly unrelated) or return and get another phone (is anyone else getting problems like I am?)

Sometimes phones have issues. I got one once that had no speakers or Mic inside... it happens lol
Try to go exchange it, and see if the next device gives you issues.. if not then you're good, if it does pick a different phone..
Do it soon though, most carriers only have a 14 day exchange period, and then after that will charge you all sorts of fees and try to fix your phone rather than just giving you a new one....

Something happened to mine with Youtube too. I'd started a video and paused it on a frame for comparison with another screen. While I was setting the other phone up, the screen on Z1 timed out. I pressed power, the screen come on and flickered, then went black!
Power and both volume keys function the same as the red button under the flap. I wasn't able to reproduce the bug.

gunna phone o2 up tomorrow and see what they say about all my issues. seems to have been fine this last 24 hours though and in their eyes that is prob reason enough not to issue a replacement.

I've had mine since Monday and this happened to me yesterday. I was troubleshooting sending MMS with T-Mobile tech support (not a phone issue as it was happening on previous phones too) and had to restart the phone several times. I noticed upon restarting that the backlight seemed to be on but the phone was not booting up. Had to perform several hard resets (both with the red reset button as well as the power/volume up buttons) before it FINALLY rebooted and stayed on. While trying to figure this out I ran a Google search to see if others were having this problem. One solution was to make sure the backlight option is checked. I had been messing with settings the night before and must have unchecked it. Since I rechecked it I haven't had the same issue.
