Xperia not turning on

today morning when i get up and try to check my sms'es..the phone is off.
i try to press the button on top but it doesnt turn on.
i plug in charging cable..it powers...but the OS never loads..and as 'windows 6.1' green window comes..the phone goes off again.
this happened 3 times.
i also removed and re-inserted battery...but still the same.
what is the problem?

It doesn't have enough charge.
Turn the phone off, charge it for a few hours (overnight preferably), then turn it back on.
If that doesn't work you might want to hard reset it (Hold left and right HW keys while turning the phone on then use the keyboard for the prompts).
This Thread deals with a very similar problem to the one you are experiancing.

thanks got it.
it is on now.
seems like the battery was totally dead.

It's funny how there is a topic about this in the front page full of responses and you ask in a new topic.

was panicky...was expecting this girl's sms.

be carefull next time before posting

Why won't my phone stay off??

I have the Bell version of this phone. I received it last week and I love it so far. The biggest issue that I have with this phone is that it will not stay off.
If I turn the phone off by holding the power button, it shows that it is turning off. 20 seconds later, the LG splash screen shows up and the phone powers back on by itself.
If I run it until the battery dies, I connect it to the charger, and a few seconds later I see the battery indicator. Without fail, within 40 seconds the phone powers back up on its own.
I have done a hard reset, and reinstalled everything and it doesn't help. Is this a quirk of this phone? Is there a fix that anyone knows of? I would really like the phone to remain off when I turn it off.

Sorry to hear you have this problem. I have not experience this problem with my phone.

Mine won't stay off if the power cord is plugged in.
So it can't charge while powered off (this is something I used to do to "re-calibrate" the battery on my Kaiser since WM6.x used to get in the way of the charging).
It could be that your USB port is damaged somehow to make the phone think that the power is plugged in?
That's about all I could think of... I find this behavior really aggravating.

My Desire Z wont turn on... [HELP]

Hey
Usually I dont use caps in titles or "help" "urgent" etc but something has happpened to my Desire Z and now it just wont turn on.
Basically I left it charging with the green led on and when I went somewhere I noticed that the green led wasnt on but I supposed that it was actually blinking notifing me of some notification so I didnt even look. When I got to my destination, I went to turn it on and usual way a press of the power button. The screen didnt light up. I supposed it was some kernel panic or something so I simply took out the battery and put it back in and pressed the power button to turn on. This is when I started to worry: It didnt turn on. I again took it out and in and still nothing. Only at ONE point did it show the white HTC logo booting then it went black again and still nothing.
I came back home and plugged it into the charger, another fear: No LED at all. Im trying it with and without the battery and it seems like nothing. Seems dead.
Is there any other test I can do or something? Im worried about it....
Also, it is rooted so if I return it, I have the warranty problem of not serving rooted devices. And I cant unroot it since it wont turn on.
Please some help
Thanks!

After about 30 minutes without the batter inside, I reinstered it and it was plugged into the charger and orange LED went up I turned it on and it turned on
Relieved but....I do want to know the reason behind this just in case next time....My warranty expires May 5 so.....
On that last note, should I unroot it and return it just to get a refund? Scared something like this may rehappen.

By default, on a nightly, it was on the interactive governor when it has always been on ondamand. After reading a description, Ive changed it to ondamand just in case...

No one answered cause this is really common and you would have found hundreds of these threads if you had searched.
Next time it happens:
Take the battery out
Wait 5mins (not 5 seconds)
put battery in
hold the power button for a few seconds
plug in the charger after the screen has light up (NOT BEFORE)!)
Phone will boot and be charging
If that doesn't work, try again but leave the battery out for 30mins.
If that doesn't work you need a new battery.

Even though it is common, why does this happen?

Nexus 4 wont turn on

Hey everyone, Im having a problem thats making me worry. I was using my phone today and for some reason the phone wont turn on after I turned it off. I havent dropped the phone at all and it hasnt been abused in any way. The last thing I was doing before I turned it off was trying to send feedback for the Yahoo Mail app because it wouldnt sync automatically, but even that was unsuccessful because it wouldnt send. So I thought I should just reboot it but afterwards its not turning on at all.
I tried holding the power button for at least 20 seconds and still nothing is happening, and I tried plugging in the power cord to see if that would help but it hasnt. Has anyone gone through a similar issue? Please Help
Thanks.

Leave it plugged in for fifteen minutes without touching it.

Try holding volume up + power to see if you can get into recovery then reboot from there.
Also, give some more details about your setup...
Rooted/Stock/What Rom/Kernel?

Yea I left it alone for a bit and then I held the power button while holding down both volume rockers and somehow it turned on. I dont know why this happened but I'm just glad it turned back on, it gave me a good scare though. I just hope it doesnt happen again

Mine is completely stock, I havent done anything with it yet

And may I ask what was your battery percentage level like after the short charge? Maybe the phone drained it all just being turned off... There were some cases of this here...

i wanted to add that i had a similar problem with my phone not turning back on. However, I managed to fix what was wrong by just plugging in the usb cable. I know you've tried it, but just in case someone else stumbles upon this thread (like me!) and has a problem turning on their nexus, I wanted to share my experience.
I haven't done anything to my phone other than add my old apps to my Nexus since I received it 1.5 weeks ago. It's stock. I've never dropped it or gotten water on it or anything. I charged it overnight last night and stuck it in my purse on the way to work. I think I briefly saw a working screen after I unplugged it this morning. However, the first time I tried to access my phone today was after I got to work. It wouldn't turn on, though that pinkish light at the bottom was still blinking. I tried calling it and the Nexus wouldn't ring even though the call went through a few rings and then onto voicemail. I tried holding down the power button for a while and also holding the power button with the volume keys to see if that would work, and it did not. Finally I borrowed a usb cable to plug it in, hoping the jolt of power would wake it up. That worked. It gave me the charging symbol for a little bit and then gave me the startup/loading screen with the glowing x made of arrows. I checked my battery and it was at full charge. Well, it was at 85%, which is odd since I plugged it in for about 9 hours last night to charge and there has only been 3 hours of non-use since I unplugged it. Also, if it was really turned off during those 3 hours it shouldn't have ate up any battery. Anyway, I just wanted to throw in my 2 cents in case anyone else has this problem. My brother, who gave me the Nexus, told me that he only has 2 weeks to return it if there's something wrong with it or I don't like it. Needless to say this gave me a scare, since the 2 weeks is almost up.

Yes this happened to me the other night. I was making a phone call and accidentally hit the power button. I then tried to turn the screen back on in order to hang up the phone and it would work. I tried holding the button for 15 seconds, tried pressing the volume up/down keys, and still nothing. I then put it back in my pocket for a minute or so and tried again. When I did that the screen came back on and the call was still active. Very strange, and I hope it doesnt happen again....

Same thing is happening to me right now.
Running stock. Not rooted. Phone charge was around 70% and I was on twitter and the app force closed. So I decided to restart my phone then went to turn it back on and it wont respond. Tried holding down the power button for 20 sec. Volume up and power, volume down and all 3 at the same time. Still nothing. Leaving it on the charger for awhile and the screen is blank no battery logo or anything.
Not quite sure what to do now?

That's scary

I get the same. I use Dophin Browser . After that i reboot my Nexus 4.

I try hold Power + Volum Down - or Volum + but get same result.
I plug in Adater and wait for it. I will check it 2 hour later.
My Nexus 4 use Stock Rom, Rooted. and this first i get this problem. Please advise me on this case. Thank
:laugh:

I'm having similar problems. Lots of random rebooting and refusals to turn back on sometimes, even though the LED at the bottom is flashing so i know the phone is still powered up. Also, sometimes when i have it plugged into a computer through usb it will get extremely hot and completely shut down, not turning back on for a long time. I called the google play store and someone is going to get back to me. I love my nexus 4 so i hope i can get this fixed or a replacement.

Nexus 4 crashed and would not power on

I had this issue too a couple of times playing Pandora through my car's Bluetooth. That was when the Nexus 4 had 4.2.1. I have not had this issue with Pandora since the upgrade to 4.2.2.
However, I just now had this issue with Movie Studio app and exporting a video I edited. It turned off its screen like normal screen timeout but then would not come back on.
I had to Volume Up + Power button for a few seconds and then release to get it to reboot.

This same thing is happening to me. Haven't found a specific cause...

Just got the same issue
Today got mine not turning on.
Managed to turn it on by holding volume up and power button together for about 30 seconds while phone was on a stock charger. After that I saw blinking orange led. When I resolved buttons there was a battery pictogram. After pressing and holding power button I finally got turning on vibration and Google logo.
The only things a made after the charging were making few photos of my cat (from the lock screen) viewing them in gallery. Then I locked the screen and put the phone on a shelf. In a hour I was not able to turn it on.
My phone has stock rom and only few third party apps installed.
I got muy Nexus 4 on 21-Dec-2012. 4 days ago I flashed to Android 4.2.2 which phone dowloaded itself. After flashing phone was rebooted.
What I noticed is that it shows 70% battery. But It was fully charged few hours ago.
30% in 2 hours! In my opinion some service/app drained these 30% by using 100% of processing power that caused overheating and/or hanging.

I too have just had this problem. And I've had it previously when making calls, the screen simply won't respond at all, its quite annoying.
This morning my alarm went off and the screen wouldn't turn on, it went on for so long I almost threw the phone across the room. I eventually held the power button and volume down/up button and then the led blinked orange a few times and the phone reset, now it seems fine.
Its a very annoying problem, and could be very serious depending on what you are doing, might have to phone the play store and tell them.

This has happened to me twice now. First time was a month ago and the second time was this morning. Phone was at 100% just woke up checked my messages turned off phone 10 min later it will not turn on. Un plugged cord re plugged cord nothing finally pressed up/down vol and power for about a minute (long minute) and the phone rebooted. YIKES!
Every thing seems normal now but I hate that scare and the fact that it has happened to me twice. Full Stock, not rooted.

Happened second time.
I was able to turn it on again by following the same steps. But this time I got some strange issue: after resolving vol+ and power buttons I saw battery pictogram with some frame with a blue background; when phone finally booted up this frame and blue background were visible through the my desktop background an screen itself was much lighter with pure colors. Only after about 5 soft resets screen seems to became nice again. Each reboot caused blue frame to become less visible. I'm confused and worried.
Also during all these reboots this frame with blue background was visible even in behind "Google" and "X" logos during booting up.
Another strange thing is that on screenshots I made this frame is not visible.

That would have to do with LCD or software..
As the battery & Google are just pictures that change. If you understand what in saying lol ?

Rooted now frozen in Installing Screen. Cannot restart.

Few weeks ago I found wife's old NST (non-glowlight model) in working order and decided to root it. Rooted it, played around with it. Wasnt too impressed, so just threw some ebooks for my kid to read while on vacation. Left it on my desk for a few weeks as I got busy with work. Today I picked it up as my son's vacation is next week and it's frozen on the "Installing... A new software update is being installed This will take a few minutes" screen.
I mean I googled for several hours, the hold the power button for 20 sec method....the hold the power and the "n" button method, I charged it, indicator light is green. I even opened it up and pulled the battery cable..... NOTHING WORKS...]
Please help. So weird...it was working fine and now frozen.

The real question is whether it is actually still on or off. What happens when you connect it to a PC via USB?

Only the green charging light goes on. I do not hear the little sound it should make when making a successful USB connection.

And I guess the drives don't mount successfully. Well, disconnecting the battery should certainly turn it off. If reconnecting makes it start spontaneously (should not), you could prepare a Nook Manager sdcard and insert it before reconnecting the battery. But this sort of sounds like the ability to boot is lost. Hmmm. I'll have to think about it.

unfortunately disconnecting the battery does not appear to do anything... screen continues to show that 'Installing... " screen. Hoping to get this thing figured out with someone's help

E-ink screens stay the same unless there is a new powered input so it could simply be off, having run the battery down completely during an update (maybe Wi-Fi was left on? That would run down the battery for sure). So if all of this happened during an OTA update, it could be really messed up
When my NST is off, plugging in the power pack turns it on. Initially the LED is green and then changes to orange as charging begins. I'm assuming nothing happens when you do the same. If the OS is scrambled from losing power during an update it may not be able to boot. You didn't say how you rooted. If you used Nook Manager you could try putting in that card and then connecting to the power pack, hoping for a boot from the SD card. If you got that far you could try a factory reset.
My power button is sometimes really cranky and a few times I've run through my entire stock of words that do not come from children's books trying to get the device to turn on. So you might try, but if it's really off the power pack should turn it on.

When I plug in the power cable the light just becomes green it never (not even for a split second) turns orange. Yes, I'm rooted using nook manager. I just suck my Nook Manager SD card in the nook but nothing happens. I'm not sure what you mean by using the power button, in my original post I mentioned I tried the power button with no luck. What do you mean by power pack?

Power pack = charger.
So if the Nook is actually off, attaching the charger with the NM card inserted should make it boot. Did you try the procedure in the link above?

Just tried the procedure of unplugging the battery, holding the white power button for 30 secs, then connecting battery and connecting to charger. There is a split second orange light and then green the first time i plug it in....subsequent plugging results in always green....the issue with the frozen screen on "Installing" remains. Tried the holding x 20 secs method to promt a restart....nothing.... what else can I do?

If the battery is actually "dead" (not impossible on these old devices), the NST will not start, even if plugged in. Do you have a voltmeter of some sort to check the battery? If it's actually charged, it should show a solid voltage. If not, that may be the issue. If the battery is actually charged then there's a pretty serious issue that can't be fixed without access to the OS by ADB, or the ability to boot from the SD card. Beyond my "pay grade", at any rate, I'm sorry to say. There are batteries available online but the price may not make sense.

I don't think it's a battery issue. I had another NST with a good battery but a bad screen (lines all across screen) . I fully charged it using the bad screen reader and used the battery from it for the frozen nook... no luck.. oh well... I guess this is a paperweight now... thanks for your help everyone.
