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.

Hey guys, my LCD broke, It was a AMOLED not SLCD, I bought this piece off ebay:
http://www.ebay.com/itm/260900702599?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
I put everything back for the second time now, first of all the device doesn't come on, but when I plug the AC power it shows charging light.
I'm pretty sure my old screen is AMOLED..
I made sure all the connectors where tight on the board. any help?
It wont power on, did I break something?
I'm pretty screwed guys, been at it for like 5 hours I'm done for tonight
Here is what I've conluded. I detached the digitizer from the lcd I made a mistake and removed the factory "tape"
Is and in the process the little power button came off.
So what are my chances now?
Can the digitizer be taped back to the lcd? or Do I need to get a new digitizer which includes an LCD? so as to preserve the factory tape?
As far as the power button goes, I'm not talking about the plastic bit, I'm talking about the actual button underneath. It seemed to be holding on my a little thread anything. Is that "thread" a connector or the button functions fine without it?
I put iit back and sealed the phone up, it seems to be pressing. But of course the phone wont still come on :/
Have you tried the "jump start" method for people with broken power buttons? ie, plug the phone into the wall with the battery out and insert the battery. It might take a few insertions for it to work.

this happened to me last weekend when i replaced my trackball. my power button gave out.
That cable is a major issue with our N1s. You can order a replacement on ebay (or other sites) for usually around $40. It is called the flex cable.
The jumpstart method should work assuming nothing else is screwed up. But it isn't an exact science. Usually if you have your charging cable plugged in, you pull out the battery and put it back in, the phone will vibrate after a few seconds and start booting. If it doesn't, pull the battery out and try again.
Hi,
I have a problem with my nexus 4,
The phone when is plugged in a wall charger or PC show up the charge animation (the lightning etc.), but wont turn on, its like the mobile dont know im pressing the power button, nothing happens :S.
Also the PC dont recognise it, the phone only starts to charge like in a wall charger but nothing on PC like it doesnt be connected :S....
I tried emergency mode but no luck, some advise ??
Can you get into recovery? Your power button might be dead

Not that I know of. Your power button is dead I presume. If you see the battery charging animation it should mean your motherboard / main board is still alive..

If this is true, do you have a suggestion for me?
I can not find anything on here with my similar situation. I dropped my nexus in the water. Put it on rice for like5 days. I charged it and got a charge signal, but when I powered it on, as soon as it got to the main screen it auto powers off. I replaced the battery with a new one AND did a factory reset. It still does the same thing.

which main screen? The Nexus main screen or the normal home screen?
It could either be
A - You might have low battery, leave it plugged in for a few hours and try turning it on
B - Your main/mother board is dead.
It seems there are already several threads about this seemingly common issue with this tablet, but I've tried the normal checks and still can't get any life out of my dad's nexus 7 whatsoever.
I've found several threads stating it's just a loose battery, but in this case it isn't. I've checked absolutely every single connection I can get to without removing the void if removed bits, and can't find anything suspect. However it still won't turn on, won't charge, etc. It's not a faulty charger or cable either, we've all got android in my immediate family and we can't get any life out of it with any lead or charger. It was simply working one day, it was turned off the way it always is once my dad had finished using it, and now it simply won't come back on again.
I also saw some people say to get it into bootloader mode by holding volume down and power straight after plugging it in, but that too does nothing whatsoever?
Does anyone know of anything else I can try, short of sending it back to Asus?
How long have you had it?
This sounds like something that should be addressed as a warranty situation, as anything else may be kludgy at best, and may fail again just after your warranty runs out.
I wouldn't really waste any more time.
JMnsHO.... :beer:
My dad has had it about half a year, maybe a little more. But he bought it from Comet, who no longer exist since they went under just after Christmas, so he can't return it to them now. Unless it'd just go straight to Asus instead.
I had exactly the same issue.......I fixed it by disconnecting the battery and reconnecting which by the sound of your post you have already tried.......you should be able to go straight to Asus for repair.......good luck....

After probably 30 days it would need to go back to ASUS anyway.
As I'd said, I wouldn't waste more time fussing with it.
They'll take care of it and still preserve the balance of the warranty.
If you messed with it too much, you may find yourself with none at all, and on the hook for the cost of the repair.
Make the call.. :thumbup:
Well I've not done anything that shows I've been in there like I say, so any manufacturer warranty should still be intact. Same goes for the software too, not rooted, on the standard rom and kernel, etc.
I was just hoping I could fix it for my dad without having to send it off.
Not yet, but anything else would be more 'intrusive'.
How long have you been working on it?
Not long, only 10 minutes here or there to see if I could find something loose. I might check the voltage of it's battery to see if it's flat, and also check to see if any power is getting to the battery while charging. That'll help prove if the battery or it's control board is dead or not.
Just checked the battery over. It's a 3.7v battery according to the label, and my multimeter shows 3.7v, so the battery is fine with no loose connections. At the connector for the power button ribbon cable, I get the 1.8v that should trigger the tablet to power up when the power button is pressed, and the power button is good too, only showing continuity when pressed. Again, no loose connections. But the bloody thing still won't turn on.
Any more ideas?
When you say that you "tried all the normal checks", does that include all of the fixes listed in the sticky dedicated to this subject?

Yes, your thread is about a faulty or loose battery. As I've said, it's not a loose connection and I've now tested the battery too. Unless you can think of something that I've missed?

That sticky has all of the well-researched methods of addressing the collection of related issues (won't turn on/won't turn off/battery status). It is not only about a faulty or loose battery - there's much more.
Give it a read and let me know if there's a fix in there for you.

I have read it all, and unfortunately there's nothing in it for me.
If your able to get to bootloader maybe try to power off then let it charge for awhile then boot, or hold the power button for a good min
It won't turn on at all, so it can't get into the bootloader. Tried already.

I know you tried almost everything in the box, but when you plug it in the wall and press and hold the power button do you see the screen light up but still black?
If yes ( hopefully ) then continue holding power button then press VOL down til arrow pointing with START appears. Cycle through with VOL down til you see power off and select.
After it shuts down unplug from wall and replug and let it sit for a long awhile
If this didn't help at all sorry......good luck....warranty?

Nothing happens whatsoever mate, even while plugged into the charger. Tried the original charger, my s4 charger, my old HTC chargers, from the pc via USB, etc. None of them make any difference.
Got a feeling it might be the motherboard, as it has power. Can't be the display since I've tried getting a logcat from it after holding the power button for a while to make sure it would have turned on. ADB just kept saying "waiting for device" as if it wasn't plugged in, confirming it isn't even turning on.
Can anyone think of anything I've missed?

Can the pogo pins be used to charge? bit of a long shot and you`d need to buy/borrow a dock of some sort. Definitely sounds like a hardware failure issue.

Pogo pins?
It already seems to be charged though.
My wife's Nexus 7 suddenly won't turn on... It still had juice when she went to charge it, but the next day found it was totally dead.
I've tried different chargers, tried to get to the bootloader, opened it and unplugged the battery, hooked it up via USB to my computer, etc and nothing will get this thing to power on.
Any ideas?

I mean, how long did you leave it on AC power? I know when I drain mine since coming to KitKat, it takes as long as a half an hour to respond again.

Sorry, it spent more than a day on the charger. Still nothing, cannot get it to respond at all.

If you haven't already, try holding the power button for a while until *hopefully* the Google splash appears.
A good way to tell if the device is accepting a current is by using a charger that can verify this somehow, like with an embedded LED. One like this: http://www.verizonwireless.com/accessories/rapid-wall-charger-with-6-ft-cable-for-micro-usb/
I used this for my HTC Rezound when it still worked to make sure it was taking a charge because it would report it was charging in the OS but the charger module itself reported otherwise (the red Verizon ring didn't illuminate unless the charger was positioned a certain way in the device thus this was the only way I could supply it a charge and not hope it wasn't dead in the morning). When my Nexus 7 is drained, it draws enough voltage to get the charger to illuminate so maybe try one of these to really make sure it's still responding.
For the meanwhile, if you do decide to buy one, what was the last thing you/your wife had done? Was there root access?

Interesting about the charger -- don't think I have one that does that. Maybe I'll see if my VZW store has one, not sure yet.
She had just used her tablet as normal, and plugged it in like she does every other day or so -- the next morning grabbed it and went to work only to find out that it was dead. IE: not turning on.
- No root access (totally stock)
- I've tried holding the power button for up to 2 mins. - nothing
- Even tried holding the down volume and power for up to 2 mins. together - nothing
- Removed the back and unplugged the battery (plug was really tight) and left it undone for 5 mins and reconnected - nothing
- When plugging in to a USB on the computer, the computer dings like I connected something but - nothing
Perhaps I'll take it apart again and see if I can get a voltage reading on the battery with my multimeter... didn't do that before, but would be good to know if it is charged and not turning on or what.

Remove the back cover, locate the plug to the battery, disconnect plug by sliding from right to left, then replug. Should be fine after that.

Thanks but I already did that. Nothing changed. If I don't get it going soon I'll be forced to buy something else as she is getting impatient.
I have the same issue.
I bought a refurbish one and it was working great for 2 days and yesterday when I tried to open it, it won't turn on anymore and I was able to browse on it 5 min before.
I tried everything but I cannot find any solution...
When I plug into a wall I cannot see the charging icon and when I plug it into my computer it will do the noise that a device is plug but nothing happen... I wonder if its the battery that is crap

I own 3 of these N7 tablets and this has been the number one issue. Sent one for repair when it was under warranty. The supplied Nexus wall charger burn out quick, and aftermarket cables last only 3 months. I've had better results using the Samsung wall charger and cable.
OP, it sounds like your wife's N7 is in APX mode. Connect it to your PC via a USB cable, and open Control Panel's devices and printers panel. If it sees an APX device, and you didn't make NVFlash blobs, your only recourse is a motherboard replacement.

I just got my new N7 32gb GSM 2012 in the mail today. Won't turn on at all. I'm not going to bother. Going to return it. Quite disappointed, as I didnt realized this issue (apparently with the battery) was so common. Was looking forward to flashing cyanogenmod. Poop. Might just get a samsung tab now, which I think is quite overpriced for its specs.

If you're seriously looking for something other than an N7 then I'd suggest you look at the LG G-Pad.
I bought one for my Dad at Christmas and was amazed by how good the screen is, and the tablet generally, for the price. The LG skin is minimal and can be changed obviously with another launcher, and the battery life is better than my N7.
