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.

can i9000 power up without the battery inserted?

I'm assuming you mean without the battery when it is plugged into the wall or a USB socket?
I can't say for sure but I've never seen a mobile that does work this way and can't think why you want to (after all it is a mobile). Having said that, laptops do allow you to do this so I could be wrong.

why don't you find out ?
it's easy, just remove the battery, and plug in the power cord
try to turn on the phone
and the result is....

All Nokia phones ive had could power of without the battery.

What?! Nobody tried this?
It took me 1 min to try this on USB connction and power plug and it did NOT power up, so the battery needs to be inserted.

My Nexus One could do that.
I didn't try with my SGS.

my old HTC Athena will not work properly without battery using stock ROM
but if flashed with a custom ROM, then it can work without the battery.
I hope we can do the same with SGS
because using stock ROM is no go

This is a weird thread.
Why just don't try it yourself? As someone already pointed out, and I will include myself here, the answer is NO.
On a side note, my old HTC Hero could power up with no battery but I cannot see any use for that, unless you are hot swapping batteries and don't want to restart your device?

NAND Phone-Off Charge Issue - *WORKAROUND*

I've been having this problem since the first installation of MAGLDR; The "Orange LED" bug, as most of us know, prevents the phone from charging while the phone is off, and the LED remains orange even AFTER the phone is unplugged. I've found a few circumstances where this will occur:
1. Powering down the phone with USB plugged in causes this issue with most builds
2. Same as #1 but when doing a reboot
3. Phone dies, then plugging USB will bring about the "orange LED" bug
I've found a workaround for these as I'm sure MANY of you have already, but I wanted to post a thread just for people who haven't found an answer yet. The following list corresponds to the items above:
1. Unplug USB before selecting "Power off" on your device
2. " " " " "
3. Kinda tricky.. a) if phone is COMPLETELY dead, pull the battery, plug USB, THEN replace battery, and b) If phone has battery and is OFF, power on phone, wait until "GO! GO! GO!" screen disappears, and then plug in USB.
I think the problem comes about when finishing the installation of your ROM via MAGLDR, OR it could be a bug within MAGLDR itself. It could quite possibly be the kernels, as JDMS' UltimateDroid ROM did NOT cause the orange LED when a REBOOT was performed...
Well either way, I hope this helps some people avoid this problem and gives the dev's something to work on.. Not that their work goes unappreciated

Or do like me. Leave the phone on, put it in flightmode and charge it.

How would this help if phone is completely dead? Seriously, this could be useful. Can someone try this and confirm?

I'm afraid to answer here as the OP might get upset, or tell me to start my own new thread.
Anyway. As I like to help people I will answer your question.
I bought a new battery for my HD2, and it did not have enought power to power on the phone (running NAND).
Not sure if this fixed the charging problem, but I removed the battery for +/- 30 seconds, reinserted the "dead" battery, plugged in the charger.
After some time (seconds) the orange battery came on, and the battery was beeing charged.
I left the phone charging for some time (expecting the light to go green when done), but it never did (NANDproblem?)
So after 1/2 day of charging, I disconnected the charger, and guess what.. the oragne light was still on.
Again I removed the battery, reinserted it again, and powerd on the phone.
The battery was fully charged, and I'm now enjoying 2 to 3 days of phone use before needing to charge it again.
Now.. I'm not 100% sure about 1st connecting the charger, and reinsering the battery, or 1st reinsering the battery and than connecting it to the charger.

I'm having charging issues but in a different way.
when i plug the charger to the phone while the screen is off, the LED does not light until I i press the red button (actually any button) to wake up the screen.
Is anybody having a similar issue?

This is not a problem for me too. The real problem is with whatsapp
when ever someone sends me a message on whatsapp while the screen is off, i dont receive it until i press the power button to unlock the screen. So i thought this might have anything to do with the charge issue.

I have no problem with this bug,he it is on the charger,so why turn it off is my question.....i just turn the sound off lol.

Nexus 7 won't turn on

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?

U need press power for 2 min and need to be pluget into wall

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.

Well, that sounds interesting. Tell me more about the APX device thing. I didn't quite understand.

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.

Galaxy s8 wont charge after being plugged into my computer

So I have a pretty interesting problem and I'm hoping somebody here could give some advice if they've ever had this problem or knows how to fix it. So here's what happened, I have a galaxy S8 and I tried plugging it into my computer to charge it, and it prompted the question something along the lines of, "this computer wants to access data on your phone" and it gave me the option allow or deny. Pretty standard stuff. So I pressed allow, and the same question was prompted again. So I thought huh that's weird, and I kept pressing allow over and over and nothing was happening it just kept coming up again. Pretty annoying. Anyways, I gave up on that after a while and went to plug it into the wall charger like I normally do, and I was surprised to see that it wasn't charging anymore even when I plug it into the wall. I tried switching ports, I tried switching cables, and nothing worked it just quit charging. And I'm just wondering what could have caused this problem? The only thing I can think of is that my computer short circuited the charging port or something, but when I plugged it into the computer again after that it still did the same thing with it asking me that question over and over again, so it obviously recognized that a device is being plugged in which means the charger port should be working fine. Another thing, when all this happened my phone was at 10% battery life, and I tried to turn my phone off and plug it into the wall that way to troubleshoot and see if that would make it want to charge. It didn't charge, and I tried turning it on again but now it is at 0% all the sudden, so I don't know why that happened either. And here's the kicker, this same thing actually happened to TWO of my devices. It's just the first time I didn't realize that it was my computer that messed it up, I just thought that my phone was defective, but it was covered by my insurance and they sent me another one for free(which is awesome). It wasn't until today when it happened again and it clicked that it might not be a defective phone but somehow my computer messed it up. Anyways, I know this was long winded but I wanted to be detailed so you have all the information. If anybody knows how to fix this your advice would be really appreciated. Thanks.
,

to be sure it is not a software problem, open the "USBSettings" by dialing "*#0808#". Try different settings (it shouldn't matter which one you choose, it's just about the resetting of whatever is in there. then connect it to your charger. If it doesn't work, I would reboot the device and try again...
good luck!

Thanks for the response. So I did try that and nothing changed so I guess it's not a software problem. And I actually have an update to the story. I bought a wireless charger and I figured that would work for sure, and my phone turns on but it just stays at 0% and doesn't charge at all. So I really don't know why it would do that and that makes me think that it's something wrong with the battery? I really dont know haha

I have USB 3.0 on my computer but I believe when it happened I plugged it into a USB 2.0. I've had issues with my USB ports acting weird on my computer before. Maybe it has something to do with that?

It's very possible as I have seen a high number of issues with USB 3.0+ and they s8 series. Always try to use 2.0 with this phone. Ive had 2 s8+ have their charging port trying to tether threw 3.0. Had to send them both in. I haven't fount the exact conflict yet but am working on it.

if you recently put it in water, it wont charge until its dry. I doubt this is the problem but its a suggestion. can you boot it up when its plugged in by holding Vol Up, Power, and Bixby? If not try the same thing with volume down. Some old phones booted up like this when there was no other way.
Good luck, this sounds like it sucks ;(
