Tablet won't power on anymore. - Xperia Tablet Z Q&A, Help & Troubleshooting

I was using my tablet while finishing charging. I was about 95%. Suddenly it just went black and won't turn back on. Any ideas? I've tried holding the power button with no results. Is there a special reset or something?
Anyone else have this issue or things I can try to fix it?

Have you tried PC Companion? Download it for Windows then try to locate for emergency repair. It will show you instructions of how to put your tablet in flash mode.

I haven't tried that specifically, but would it not fail if the light didn't even go on when plugged in, and my pc doesn't even read it as connected?

Not really, for example in some samsung devices even if the device wont turn on the a JIG plug was able to put the phone on download mode, something very similar to flash mode on the xperia mobiles.
So i guess the last thing you can try is to put the tablet in flash mode, you can download a FTF file with the firmware compatible with your device, and download flashtool from: Click here to download and then put your tablet on flash mode. I guess you will need first the drivers Click here to see drivers and after you install the drivers, just open flash tool press the vol down key and connect the usb cable to the tablet, and if you see that flashtool or maybe windows recognizes your tablet you may have luck to restore it.
So if you get it into flash mode, then just flash the FTF and let's see what happens.
Let me know.

I will give it a test this evening or tomorrow - thanks! I will post back if it works.

PC Companion doesn't detect the tablet, nor does my PC at all in device manager. It doesn't respond like anything is plugged in, but it did before.
Flashtool comes up with nothing either - once again doesn't even acknowledge anything is plugged in.
Thanks for the suggestions, though.

I read your issue. Read my first post again - yours is simply a crash. Mine does not charge, has no power LED, and is completely unresponsive. No recovery button combination or anything works - yours turns on and responds to things.

so when you try vol up and power button do you not see the white led flash once then a couple seconds later three times? if it does it means your tablet can still be put into flash mode with some perseverance.
Edit: you could try sony mobiles flash tool called Emma which has its own way of entering flash mode (think you hold vol down and plug the usb cable in the computer) and see if that program can detect your tablet but you can use the instructions provided on their website if your unsure what to do.

same sitation
I have the same problem with my tablet. I watched stock photos in album and then display switched off. And that's the end.
Nothing happens when I try to power on, reboot or restore with Companion. Computer doesn' detect device. The same situation with Emma and flashtool.
I used my new-bought tablet only for 15 minutes)))

Mine ended up needing replacing due to a fried mainboard. Did you leave yours plugged in overnight?

Ok something strange happen to the tab I never had problem before I left the headphone plugged in a press the power button to close the screen (I always do that) when I try to use the tab there was nothing on screen double tab the screen nothing, hold the power button nothing put the tab in the cradle nothing the led was not turning on but the usb cable direct to the pc and than the charger nothing. I press the volume up and power button the tab led blink and was able to restart the tab. ??????????

Same thing just happened to me. Power button would not turn on the Z. LED would not turn on when charged. Did a hard reset and it came back on. Model: SGP312.

Pc companion will not work in thta situation cause it needs the device to be powered on...
In that case have you try the SUS http:/sonymobile.com/gb/tools/update-service/
Just follow the instructions and you will be fine
It will erase the entire internal memory though, sd is fine..

[Q] No Recovery, Black Screen

Hi,
i bought a Touchpad on Ebay. The problem is that i can't get it into Recovery or anything else. The screen went all black. I tried several key combinations (volume up + power, home + volume up + power). When i plug it to my pc it recognizes a device. I also tried the WebOS Doctor but no success. Is there a other possibility to bring it back to live?
Greetings Markus
You say it's recognized, so that's a start. Try this:
Press and hold VolUp + Power, then repeatedly hit Home about 15-20 times. You won't notice anything happening, but that forces it to do a hard poweroff. Then, press-and-hold Power + VolUp + Home, and that should turn it on in WebOS Recovery Mode.
Actually, you dont have to do all these weird button combinations to get into recovery. just holding down the home button and the power button for about 10 seconds forces a reboot. When it restarts, but before the HP logo appears, just hold down the volume up button to go into webOS recovery. You will know you are in recovery when you get a big usb symbol in the middle of the screen. If you ran the webOS doctor, you would have had to do this so when you say you ran the doctor, did it actually run it?

Hi,
thank you for your answers. I have tried these combinations several times, but with no success. But I can hear, when the device is connected to my PC (Windows), that peep peep sound when you plug in an USB device. So there will be a reset of the device i think.

Maybe the screen is dead. If your Touchpad is off, I dont think the computer will recognize it until its turned on. If your computer is recognizing it, I would think that it is on, just not displaying anything. When you press the volume buttons, do you hear any sound indicating the volume is being adjusted?
When you bought it off of ebay did you make sure it didnt say broken or for parts only, something like that? How much did you buy it for?

Deleted partition? Thats probably not good. So did the seller actually describe that it wasnt turning on and working? If, somehow, they deleted the whole operating system off of the tablet, including recovery, you might be in a bad place with that. There MAY be a way to force load webOS on the device but I, personally, don't know about that. Someone with more computer skills will have to help you. If the seller didnt explain that it wasnt even turning on, You should try to contact them.
Hi, he did mention that.
But i thought the recovery mode still works. So my fault.

Ah. Well I dont know if there is a way to get it to work. If anyone can help you though, it would be the people over at webOS Nation. Maybe try asking over there. webOS devices are their thing.

Tablet not booting, not led on chargin...

Hello, last night I turned off the tablet normally without problem, and since then, it doesn't turn on, either the led notification when charger is connected. I tried to hold down the power button 10, 15, 30 seconds and holding Vol + and Vol - and nothing, no response.
My only chance is to go to SAT? My tablet only has 2 months...
Thanks

I have guarantee for him but I would like to ask you first if maybe someone already had this problem and is able to help me. Phone was plugged in all night to the charger but it did not help.

None of these methods has not helped. Phone does not vibrate at all when hold power button and volume up button.
Only a turn on for a while the red led in the support zone when he has displayed in order to connect your phone to your computer to update, but the computer it has not detected

[Q] Phone will not tuen back on

In sum, earlier today I was using my phone with no problems-- calls, texts, using apps etc. I went to 'close my screen' when I was done using it and I realized the side power/lock screen button was not working and my screen was not responding when I wanted to lock it. I removed the battery hoping it would reset the phone and fix what was wrong but now my phone will not turn back on. I plugged the phone into the wall for at least 30 minutes as well as plugging it in the computer for quite some time. No response from the phone at all. (no charging icon, computer is not detecting the usb cable when plugged into computer, etc.)I also held the buttons down to try to power on as well.
I was wondering if there was a way to fix this problem, or somehow retrieve files (mainly pictures) from the phone,
Thank you for your help. Any feedback will be greatly appreciated.

I attempted to hold volume down, power and home buttons but the phone did not respond. The computer is also not recognizing it while plugged in via usb. The button does not seem to be 'stuck' as i can still hear a slight clicking sound when I press it.
Try removing the battery and hold power down for 30 seconds and then try installing the battery again.
Try that ^
maybe a jig might help

Help, blank screen and unable to boot

I was searching for a solution for my contact sync issue and I needed to reboot. After pressing reboot, the screen goes blank and I cannot boot again. Volume up + power doesn't work. Plug in power and the light didn't turn on. Even try to hit the tiny hole that looks like reset and that didn't work with. Help!
I am on official miui 9 with Google installer
Did you hold the power button for a longer time?
Yes, try holding the power button for some time. One time, after fastboot, it took around 90 seconds to power up.
there's a tiny hole that looks like a reset ????
did you poke the mic hole?

Hi Rioru, did you ever find a solution to your issue. After charging last night, suddenly I had exactly the same error. Which means I cannot boot the tablet, Power+Volume UP does not respond, charging LED not responding and after connecting to a PC I cannot not establish an ADB connection.
Thanks!
