When you plug it in, does the charging light come on?
How long have you tried holding the power button for? 10-15 seconds should give you a full reboot...but if nothing happens then it could be frozen, in which case you will have to let it sit until it drains.

no power
yes..when i plug it in the red lite is on...i have held the power button for 10 to 15 seconds and tried power plus volume up..still nothing

I second the "Letting it sit until the battery drains" worked for me once.

how long
thanks for the quick reply..one last ?...how long does it take to drain battery completely?

Depends on how much charge it had to begin with. I would guess about 10-15 hours with full charge. If you get really impatient and dont want to wait, you can take the back cover off and push the reset button.

From 85%, assuming your battery stats are correct then I'm going to say it won't be drained fully until maybe tomorrow evening or night and even then it may still have juice. The problem is we don't know what state it's frozen in. Is it frozen with the processor speed reduced? Is it frozen because there's a rogue app and it's flexing the processor? No idea.
VS REALLY dropped the ball with not having a removable back plate as well as no access to the reset button.
Ah well.
Good Luck.

Try volume down then power button. This worked for me once.

let us know how it goes

You may of already tried this, but....
Did you try holding the power button for 15 - 20 seconds? If so letting it completely drain may be you only option left.
Update you ROM to one of the newer ones. I have read of this happening to others running one of the older ROMs.

I thought my Xoom was dead

Last night my Xoom went into sleep mode after I had looked something up as usual. When I went to use it again, it was dead. Absolutely nothing. Plugging in the power cord never showed it getting a charge. I seriously thought it was dead for sure.
Solution:
Hold power button and volume up button and system came back to life...sort of. I got the motorola logo but at the top of the screen it said something like Starting RSD Protocol 3 and just sat there. Release both buttons, did the same procedure and she roared back to life and is working fine now.
Just thought I would share that in case it happens to anyone else.
Same happened to me about a week ago; My Xoom turned off and would not come on or even start to charge when I plugged it in, I was freaking out, then I accdently hit vol up while trying power for the mill time and it turned on...
Just hold down the power button in it will do the same but just don't load in bootloader

Mine just rolled over and played dead as well. I had about 3 quarters charge, put it in sleep mode and then nothing. Holding down the power button did nothing as well. And like the OP, I had no charge indication when I plugged it in.
The volume up and power combination did bring it back to life. I want to clarify for others who encounter this that just holding the power button alone did nothing.
Sadly I had to look up the fix on my wife's iPad2.
Fortunately she was not home to see that...
Did you flash a kernel? I had the same issue with a kernel I flashed from the Ubuntu thread in the dev section. I flashed to a Tiamet kernel and it went away. Before that I flashed the stock images and then the kernel.
I think its kernel related.

Sorry. It was bad form of me to leave out the OS . Mine is a factory stock Verizon.
I had a similar issue with mine a few weeks back. Battery was at about 50%, plugged it in to charge when I went to bed and woke up and it was completely dead. It took me almost a half hour to get it to start charging again so I could power it on. I didn't do anything fancy with it, no power / vol up magic, it just suddenly decided to start charging again and would power on. I still have no clue as to what the root cause was to my problem, only happened once and no issues since.
I'm running a stock 3.1 ROM and kernel but rooted.
Same thing happened to me last night. Plugged in before bed and wouldn't power up in the morning. I freaked as my Xoom is less than a week old. Power + vol up was the only solution. Strange, but judging by this post this seems to be a trend, hopefully one that will not be a regular occurrence.
Running stock rooted rom with Tiamat kernel conservatively set to 1.2 ghz, although it seems this problem isn't confined to a particular kernel. Wifi only HMJ37 (US) model - It would be handy if everyone with problem reports with their hardware version and kernel etc so that any trends may be documented.

Is your power button maybe recessed or stuck? Could be causing it.
You can follow me on Twitter - @NotSo1nter3stin
If it means aything it feels fine and passes CWM button test just fine.. It still has that slight click to it
EDIT: Ok upon checking again, as i haven't actually tried in a while it dosen't straight reboot, it reboots to recovery/CWM, the only reason i want ti to power down it to do a full charge on the battery, now i have been told this is frivolous but hey my battery is old, got the Shift when it first came out and it still last two plus days on a charge

You get two days out of an original battery . I would be very happy about that. If what your saying is that when you power down, and then plug it in to charge it reboots into Recovery. Then that is normal, it happens a lot on rooted devices ( not all but a good portion ). As for your device just rebooting as soon as you stick the battery back in. I'm going to have to agree with notso on this and say something is wrong with your Power button. It should not be doing that. I had that happen on a Shift that had been dropped. Turned out the Power button was damaged. It was stuck half in. Which caused a bunch of weird things.
Well then I guess I cant complain, but yes I get more then 48 hours from a charge, I charge it over night every other night and try to deep charge it once a month, seeing as i cant use mine to do it I use my wifes, my Full charges consist of Complete discharge, Charge to 100%, power down and leave on charger for 1 hour, then power back up and leave on charge for another hour once in a while during the Full cycle clear bat stats

I am able to get 2 days out of the the 2000mah or the original battery with drob's latest kernel.
Actually, a brand new factory battery seems to hold up better than the 2000mah batteries we got.
It's a htc charging while off issue if it powers itself into recovery once your phone shuts off. You'll need to talk to koush about it because the older recoveries can power while off but the newer ones can't because the older method no longer works on the newer recovery source code.

HTC Sensation Power Button (On/OFF) doesn't work.

Hi everyone. Today i was chargin my phone at PC using a no-name usb cable. I've noticed while it was charging that the screen kept turning itself on and off. When i finaly took the phone, the screen was unlocked and when I tried to press the home button it did nothing but taking screenshots (like the power button was stuck). The power button was not wroking either.. After I took out the battery and restarted the phone, the power button didn't work at all. Tried to clean it off using this method but it did not work. Tried to clean the power off button using a method i've seen on google (can't post the link since i'm a new user) but its still not working
I'm desperate, please help
Are you sure, that the problem is only the power button? I have sometimes problems with this phone too. Sometimes you can't turn it on.
Try taking the battery out for at least one hour - then try to start it. I had always success with this.

The batter has proven me to be fcked in the last week, had lots lots lots of random turn-offs and restarts. But for more than 5 hours the power off button didn't work.
I'll let my batter out through the night.
Thanks for reply.
PS: I'm running ARHD 7.3.

The restarts can also result from a loose battery. Try putting a folded piece of paper between the battery and the upper casing of the phone, so the battery is pushed against the pins. This is a well-known issue. It helped me a lot. Before I had also lots of reboots.
Yep, did that in the last 1,5 year and the random reboots stopped. But as i've said, now it happens even tho' i have a paper that keeps the battery steady.
Lol just took the phone to see if the power button works and currently i'm talking screenshos pressing the home button .

Well, this isn't normal. Is your power button constantly pressed?
Try the following: Hold the volume down-button while inserting your battery until the phone boots up.
Does it boot into the boot manager?
Just woke up, plugged my battery in and the power button worked almost normally. Could've pressed it 5 minutes and after that and a restart it didn't work anymore.
This means I should buy a new battery and everything is fixed? Are the Anker batteries worth it ? Or do you recommend me a HTC EVO 3D battery ?

You can use the battery from the Sensation XE, which has 1.700mAh instead of 1.520 (or 1.560). At the HTC-Store they are about 50 € here in germany.
Always buy original batteries! Not the cheap ones from eBay. They usually don't have a temperature sensor, so the phone can't shut down, when it gets too hot while charging. This can be very dangerous.
I haven't got any experience with Anker-Batteries - sorry.
Pressed the volume down button and it got me into the boot menu (just like the power button is kept pressed).
Do you think that if I change my batter it will fix my problems ? Also noticed that my battery is altered, aka its not flat but swollen.

If it is swollen, it is definitively broken. Mine had the same symptoms...
I'm pretty sure, the powerbutton-problem isn't related. Does the button feel normal, if you push it? Or is there no "click"?
Maybe you can repair it with a needle by lifting the foil a tiny bit.
i dont think you need a new battery, same problem occurred with my phone, done some DIY fix and written that in a post for fellows like you in search of help.

Battery drained, phone does not turn on.

Yeah, so the battery got drained, and now the phone will not respond to anything.
Pwr-btn + both volume-btn for ~20 sec did nothing. Will not take a charge from either PC or adapter.
I will be leaving it overnight in the charger.
:crying:
UPDATE
Contacted Nokia Support via webchat.
After some confusion, they suggested only;
Hold vol+ vol- & pwr buttons for ~20s
Hold pwr button for ~30s
If repeated tries does not turn the phone on, then contact local Nokia Care Shop

Put phone on charging. Then while it's on charging
Press VOLUME UP & POWER BUTTON till you feel a vibration and Android logo with 10-9-8-7 counting.
It'll open up in RECOVERY.

What happens if you hold the buttons like that? A hard reset? Or anything else?
It should go into Recovery, if you keep holding.
How long does it take to go into recovery mode ? I have been holding it for 5 mins now.
Any help would be appreciated. Thanks !

Not to be skeptical or anything but how do you hold down the home button on a phone with soft keys when the phone is off?
---------- Post added at 11:56 AM ---------- Previous post was at 11:52 AM ----------
I had a similar problem too, but I was too impatient to try the methods that required waiting for days. I voided my warranty by opening the phone, disconnecting the battery and reconnecting then closing back my phone. The battery started charging afterwards.
If you decide to go this route, i suggest you lookup information on nokia 3 disassembly so as not to mistakenly mess anything up
Well... I bought a nokia 3 today and after only 2 hours of use, wich included 2 software updates (from 7.0 to 7.1.1 and a november security patch) phone turned off, it was like 48% battery and sudenly it turned off.
After a couple of minutes I connected it to the charger and it's charging now, it says battery is 0% charged, so it went from 48% to 0% instantly. Appearently battery calibration is way off in this phone, just like the first generation of android phones when samsung and other brands didn't know how to make android work properly. I'm completely sure it's software related so hope they fix this in the next update soon.

Well ususally they recommend that you fully charge your phone after you first buy it (although i'm not sure how valid that instruction really is)

My LG G7 won't turn on

My LG G7 (T-mobile version) randomly powered off twice and now it won't turn on. The first time it happened was earlier this week and it was off for about a day and a half, and the second time happened around two days ago and it still won't turn on. I tried everything I could think of to get it to work again including: Holding the power button and volume down button and waiting for 8 seconds at the minimum, taking the back out and trying to adjust the battery, holding the power button by itself for at least eight seconds, and leaving it in the freezer for 30 seconds didn't work either. Is there anything else that I can do to fix my device? Please help, I love this phone and I want to use it again!
It seems to be battery failure. Is the battery replaceable?
