Broken Power Button

My power button has been acting funky lately, i thought it was just a software issue until i switched my battery today and realized it was hardware. now i cant turn on the phone.
Is there anyway to power on the phone via fastboot or some usb command? i need to get some files off the device before the device swap but i dont know how to turn it on without the power button =[
any ideas?

One of the bloggers on Droiddog.com had the EXACT same question. Yes it's possible... read her method here:
http://www.droiddog.com/android-blog/2010/06/nexus-one-power-button-failure/
Basically:
Plug the phone in– USB or AC works fine.
Wait until the charging light comes on.
Remove the battery, while leaving the phone plugged in.
Replace the battery.
After about 3-4 times, the phone should boot.

i need to know if i can turn it on via usb command, ive already called in for the device swap.

it worked!!!!!!! fourth time it started right up. thank you so much you saved my life
if you take it out and wait till right after the charging light goes off then put it back in it seems to start up a couple seconds later!

Glad you got it up and running. Sorry I misunderstood the question.

Fire on CM9 won't turn on

[SOLVED]
Hello all,
So I went to turn on my Fire and wanted to boot into recovery so I long pressed the power button (+20 secs). Now my Fire won't start up. I get the momentary green light which comes on but no boot up - just a black screen.
Any ideas...i.e. help? Cheers.
For info I'm running (or I am normally...hehe) CM9. Cheers bis...

does the green light stay on if you turn it on ?
or is it "blinking" - like it reboots ?
cm9 seems to drain the battery in some conditions
may be charging with the wall charger for some hours helps
do you see a sort of backlight on the black screen ?
would verify it with hard power down to see the difference

The green light only comes on for a second after pressing the power button. The screen is completely black. What is a "hard power down"?
Also, plugged into the outlet there is no light, charging or otherwise.
Cheers for your response and help. Much appreciated.

hard power down is meant to hold the power button for ~20sec - till it turns off
if you plug it to the wall charger it can last up to half an hour till the orange light comes up when the battery is heavily drained - would recommend to let it on the charger over night in such a case

Oh yes, that's what I did initially - which I assumed put me in this state. But it might well be that it powered down completely. It's plugged in the outlet so I'll it charge more. It's been charging for over 3 hours and there's still no light, orange or other.

hmmm - the strange thing is that nothing shows up on the display - this implies that it don't have enough power to start to the bootloader or the bootloader is messed up
if the bootloader is messed up there is only one way to load a new one
you have to open the kf for this ...
is it recognized at the computer in any way (shown up or the typical ding ding sound) ?

Problem is I don't have a computer now...I'll leave it plugged in all day and hope for a change of some sort. If not I'll have to do another one of my now famous calls to Amazon. "I don't get it...it just won't start..." And two days later another one arrives. I have to say they are incredibly accomodating on that front...but I'd like to avoid it. Three times is pushing my luck I think...

Yes, that's my experience. I just say "the screen is black and it won't turn on" - they've never had a problem with it.

Well, a thorough charge solved my issue. After the charge, I did a hard power off and then powered on normally. Whew...
Glad to not have to send it back to Amazon...I shall make sure it is fully charged from now on.

glad to help ...

bricked? red flashing led

Just got my nexus 4, and after it was left in cwm for about 10 minutes (while I was making breakfast) it went to a black screen and now just the red led notification led is flashing whenever plugged in, and on my mac in system profiler it shows "composite device", any suggestions?
Thanks!

Don't know if you want to do this, but you can open the phone and disconnect and reconnect the battery connector...

What was your battery level, I know in other devices some times the CPU(s) run at full speed in recovery allowing for quicker flashing this could discharge the battery rapidly. Also a flashing red LED when plugged in normally means the phone is charging but doesn't have enough charge to reliably turn on, leave it plugged in for about 15 minutes and try turning it on again.

Try holding down the VOL + and - keys along with the powerbutton (after turning it off by holding down the power button for an extended time) and see if you can get into fastboot. My friend's Nexus 4 kept bootlooping after he unlocked the bootloader but booted straight to CWM after, not letting it erase userdata first.

I have no problem doing this, the phone seems easy to disassemble, looks alot like a overgrown iPhone 4, 2 screws on the bottom. I just hope its an easy slide, I don;t want to mar it in case I have to exchange it.

I thought this as well, its been plugged in for at least an hour now.
Oh and now I don't even get the red led!
good times..

I've got the exact same issue. Plugged it in last night to charge and this morning it wouldn't turn on. Plugged and unplugged it and the red LED starts flashing. After a minute or so I'm getting the battery charge animation on the screen - so the red LED is power related. Now to see if it actually charges up and boots.

Hi nycbjr. I have seen a similar issue posted here, but I can't find the thread at the moment, try searching. If I remember correctly then he got it working by holding power, volume keys and then plugging in the charger.

Here seems to be a similar thread, maybe you'll find help there.

I think I'm bricked?

I thought I'd clean up the OP for folks who got here with similar issues as me since it seems more common than we'd like.
Scenario:
Phone does not turn on without the charger or USB plugged in.
When plugged in, it boot loops at the Google logo (i.e. turns off at the logo, and reboots) and gives what is beginning to be referred to as the the 'red LED of death'--where the LED just blinks read.
The bootloader is accessible when plugged in. But trying to boot into recovery causes a loop. If you try to enter recovery, the phone has to turn off then boot back into recovery. But turning off means that when it turns on it will loop at the Google logo. So, booting into recovery is NOT an option.
Download mode is also accessible when plugged in.
Since the bootloader is accessible, it is possible to flash the factory image to the phone, however, doing so does not resolve the boot loop, nor does it allow the phone to turn on without being plugged in.
Fixes which have worked for some people
Instructions in this post worked for a couple people. NOTE: you have to be able to get into the bootloader for this to work.
One person who left it in download mode plugged into the PC (which was off) overnight, and somehow the problem was resolved. Thread here.
Here's a post in this thread from a user who was able to get it booting up again by leaving it on the charger for a bit.

You fool.

When I plug in the charger, there's the battery icon with the lighting bolt which I think indicates that the battery is dead. But it's not dead, it was around 95% when I started Antutu. So, it's constantly turning on and off showing that battery icon while plugged in, but doesn't start up. Anything I can do about this?
Also, the computer only detects it briefly, before the phone turns off again, so ADB/fastboot/toolkit seems out of the question, because it doesn't stay detected long enough to do anything.

Tape the power button down so it goes into a power cycle. Leave it until the battery is totally dead. Then plug it into the wall outlet, let it fully charge. Then try turning it on.

I would say try this to drain the battery. Then charge it and see what happens.

So how exactly did the phone brick? Just so everyone here knows what not to do. Is it the kernel that caused it since its still in experimental stages?

Have you tried reflashibg or using your nan droid back up from the recovery console?
Just because our won't not does not mean it is bricked.
It is really ticking me of that many people do not even have our phones and you are exchanging because of ignorance. Surely all these exchanges must impact stock. I know they keep extras but how many?

That's the point. It'll turn on and off until the battery is ACTUALLY dead. Then, charge it fully, and try to start it.

Dude this happened to me last night! Same ROM kernel combo! And fired up an tutu after ocing point is this should not be happening just made a thread and seen this here! Freaky! I'm telling u people beware something is up for sure been doing this a long time never seen this before

First if you have an unlocked bootloader, your replacement won't be free. As soon as Google gets it and realizes it's unlocked they will charge you full price for your replacement.
Second, Nexus devices are next to impossible to brick. There is probably a way to reset the device. I would try first unplug the device from your computer or charger and try holding the power button for a full 15-20 seconds. Then try booting into bootloader or recovery. If that doesn't work, try holding volume up and power for 15-20 seconds. If that doesn't work, try volume down and power for 15-20 seconds. And if that one doesn't work try holding all 3 down for 15-20 seconds. This sounds like a problem that would more than likely be fixed by removing the battery and rebooting. Since this doesn't have a removable battery there has to be a built in 'hard reset' that will power cycle the phone.
I am willing to bet there is a way to get this working. I guarantee if I had it here in front of me I could.
Also, like someone else has said before, if you are a not good at diagnosing problems, troubleshooting problems, fixing this kind of stuff on your own and adb/fastboot, it makes no sense to be using experimental software on your device. Especially if you plan on pushing its boundaries by overclocking and running benchmark software. If I were you, after you get this straightened out, wait a while until stuff is more ppolished and tested better.

So, by sheer luck, I was able to get into the bootloader and have it stay on. I was then able to use the toolkit (option 9) to flash the google factory stock image. This completed successfully, and I was also able to re-lock the bootloader, but I still have the same problem as I did before: battery charging icon and constant reboot. So, it's completely stock now and the issue is still there. Would it be reasonable to assume that the issue isn't software and I somehow got a hardware failure?

Yo hold power down then plug USB in then right after hold all three button .like after u plus in USB while holding power button then at same time hold volume buttons also this is how I got into download mode.....but.....phone was not detected and comp SD there was a driver failure. But yes dude phone was charged. And I had same exact combo as u I mean same exact. This is why it is freaky. Aokp was fine all day then when I flashed faux test kernel and fired up antutu I just had a flash then nothing. Not blaming anyone of course it was me who chose to flash after all this is custom software and I love these guys work just wish I knew what did it ....like what actually did it

Last ditch effort is to unscrew the two t5 screws at the bottom and do a real battery pull. Probably wont work, but what do you have to lose?

[Q] Nexus 10 wont turn on.

I placed my nexus 10 on charging yesterday, and after a while (2-4 hours later) when i came back, i found the device to be turned off, I tried the power button in all the combination with volume buttons, but still no luck (even held the power button for 3mins) I searched online, and couldnt find any help on other forums. Some said to keep it on charging overnight and then try powering it up. But still no luck.
I dont get any notification when i connect it to charger, although when i press the power button while connected the screen lights up, and battery charging sign shows up.
Any help would be greatly appreciated.

Could be a bootloader corruption, software issue, hardware issue or some part of the hardware "thinks" that it is still on when it is not causing it to not switch on.
Have you noticed any issues before it just came off like extreme overheating?

Well, yes the tablet was getting overheated after a long session of hd videos, or games, but that use to happen all the times.

I believe this is normally called a "Sleep of Death" or sometimes "screen off death". Hold power + vol up + vol down at the same time for 5 seconds and you should boot into fastboot. From there hit the power button to turn the tablet on. Then go about finding a better ROM/kernel combo that doesnt give you this problem.

I've had my Nexus 10 for less than a week, and this morning I encountered this problem. I was working on setting up syncing through an app called FolderSync and SugarSync. Syncing of one of the folders seemed to go into a loop. The device locked up completely a couple times. I got the process running again and left it running while I went for a workout. When I came back no way could I get it turned on.
I had tried all the things suggested here before checking here for help. I'll try your "solution" of leaving the device on charge overnight. If I can't get it going tomorrow morning I'll return it to Staples, where I bought it.
I have an iPad and have never encountered anything even close to these problems. Bought the Nexus 10 specifically to run the Vim Touch app for Android. The only Vim app for the iPad is horribly crippled.
Sounds like this thread pretty much exhausted the possibilities by the time epicbearman discovered his "solution," but if by chance anyone has any further suggestions I would be grateful.
Thanks,
Eric Weir

I had the exact problem as the OP and none of my chargers worked. I then googled and found someone that said to try to charge via their PC USB instead of the wall charger. I left it plugged into the USB for a couple of hours and the charge went to 4% ( so it must have been very dead ) and all is well.

I charged it via the usb charger, and connected it to my pc overnight. Try doing that.

Thanks. If I'd gotten this in time, I suspect it would've worked. But when I couldn't get it started after trying everything else and leaving it on charge overnight, I returned it to Staples.
Will order a Nexus 7 from Google. If I can get Vim Touch running successfully---my reason for wanting an Android tablet---and I find the screen to small for heavy writing---I want to get by with a soft keyboard---I'll order another 10 and give the 7 to my daughter.
