FYI: Cannot turn on Tablet Z2 - Xperia Z2 Tablet Q&A, Help & Troubleshooting

Some how after over night USB charged, in the morning I cannot turn it on.
Seaching through the web found it is one of the common problems.
However, after try all many many times and also continue charge more nothing happens.
It seems it is not charged, no led on and the magnetic indicator shows not charging.
(Un)fortunately , it is long holiday then I have to wait for the service center.
After left it alone for 2 days, now I can turn it on but the power is out.
Then over night charge again and now I will upgrade to Lollipop.
:laugh:
FYI:
If you experience same as mine and no warranty may be wait.
But, if in warranty you may or maynot.

Had the same problem some weeks ago, same steps and it was working again.
BUT: now it's dead again and it doesn't come back to life since over a week!
Maybe it's better to repair it if you get this error before unlocking bootloader...

Thanks, but as it is working I dont think I can claim.
And warranty will expire soon early next month.

Has anybody experience with warranty in this case with unlocked bootloader?

Tried to get it repaired here in Germany: came back unrepaired because of non original software.
Well, when it does not poweron nobody can check the software. So it looks like they simply compare the serial with an unlock database and deny repair without looking for the error at all.
That's nice for an device with this known fault also with original software and locked bootloader...

That's really too bad. I have the same issue with mine. I created an RMA in march and it expired now I'm out of warranty ( by two weeks) and Sony wont help.
For what its worth, when my tablet has the power on issue, if I plug it in to charge with my blackberry playbook charger, it will charge enough to power on. The OEM charger won't work the same way. Once my device is on, the OEM charger works fine.
You may want to try this method. I think it may has to
do with the amperage that the BlackBerry charger drives that semi solves the problem.
Here's a link to the charger
http://www.amazon.com/Blackberry-Folding-Blade-Charger-Playbook/dp/B004OZMWUS

3 rd time
My tablet went deep sleep again, and it is 3rd time.
Last 2 times, I left it drain out battery until it active again and show low battery.
This symtom, we cannot do anything not even flash it.
But this time after left for 40 hours, the battery still not emtpty then I try:
Reset it more than 2 minutes, nothing happen.
Power + Up, nothing happen.
Then I try Reset and push power, suddenly it vibrates.
Tada...Sony logo shown and working again.
The battery is 13% left.
As it cannot be re-produced, so if anyone experience try Reset + power.
Please let me if it help or not.

[Q] [XMP] Battery Suddenly Discharging way too quickly

Hello XDA,
Yes, I know you've seen questions like these before but hear me out; I've tried practically everything I could and wanted to know if there was anything else before I go to a service centre.
Situation: One day, randomly, my phone decides to start discharging its battery as fast as it can. That night I turned off my phone at ~30% and the next morning it didn't turn on at all. i.e. battery was draining while the phone was off. The next night I tried removing the battery while sleeping. It was about ~40% when I turned it off. Next morning I turn on the phone and whoa the battery is 50%.
This happens even when my GPRS/EDGE is turned off, the sync is turned off and no apps have been installed.
What I did: (Apart from going to the SE service centre, of course). I tried doing a battery recalibration.
1. Drained it fully. Charged it. Turned off and charged it to full 100%. Removed batterystats.bin. Nothing happened.
2. Drained it fully. Charged it. Drained again. Charged it for 8+ hours while turned off. I still don't know if this has had any effect.
3. Did a complete factory reset. No effect.
4. Repaired the phone using SE repair. No effect.
Does anybody have any other idea?
Oh I don't have any idea but to say good luck and sorry for your trouble and I hope that doesn't happen to my xperia.
if you've exhausted all possible troubleshooting, then, bring it to an SE service center .. you might also want to buy an extra battery along the way ..
download Android System Info from the market and check your running apps/tasks...
should give you insight to which app/s might be gobbling up resources...
that is, if you haven't tried doing that yet...
I have the same problem a months back. Do you by any chance use a portable charger? Portable charger can screw up phones like that. If not, then it must be faulty charger. But the bad news is that it probably hardware. If you are lucky, it's the battery, you can get a replacement for a week from SE or you can just buy a new one ( I recomend the the original SE branded). Or if you are unlucky, it's the whole hardware, which mean you have to turn it in to SE, wait 3 days only to be told that it will took them a month to repair it. Either way, you should get your phone to the service center ASAP.

Man that sucks. Will have to take it to the service centre on Monday, then
It's usually an app, that dosn't terminate properly. You can see it in Battery history, when the phone does not seem to go back to sleep mode. The app is usually the one on top in 'partial awaikening mode' (translation from german) and keeps the phone in this mode, what drains the battery.
Happens here from time to time. The default music player from SE does it almost everytime. Last time for me it was netcounter.
Either killing this app or reboot fixes the problem.
Hope that helps...

[Q] Charging issue when phone is turned off

Hi,
I hope I am on the right thread.
This issue started one week ago. I have a 4.1.83 (no root, no G-blur or any specific customization beside the ) just the stock Atrix phone.
When my phone is turned off, if I try to plug it into the wall with the moto charger the red Motorola logo came on, then disappear then came back on and keep doing that (on and off) - infinite rebooting loop. Before, the battery charge status would come on and the phone would charge fine.
Now it just does this unlimited reboot on the red M logo.
If i turn on the phone without the cable, the phone turns on fine and i can charge it with the wall charger after the phone is booted. But not when the phone is turned off.
Do you have any ideas on what is going on and how to fix it?
Thanks for your help.
Hmm... Is the charger the one specifically designed for your Atrix and you're sure you haven't done any tweaking to the phone?
Absolutely certain. Am using the original Charger and did not try to do anything special with the phone...I did not touch any system file nor tried to tweak anything.
Phone is 'stock' beside few apps I installed several weeks before the problem starts to occur.

If you had rooted, etc. I would say flash sbf and start over, but since you are stock, I would return it for a warranty replacement.
Can I do that even if I have owned it for 3 months?
Thanks!
I have the same exact problem but I have my mobile flashed, plus bought mine from eBay. Should it be a software issue?

You have one year warranty through Motorola. See warranty section in the following:
http://www.motorola.com/staticfiles/Support/US-EN/Mobile%20Phones/ATRIX_4G/US-EN/Documents/StaticFiles/ATRIX_LG_68014203002A.pdf
If the phone is defective, you are covered. If it's accidental damage, you would have to use your phone insurance through your carrier.
Can't be accidental...Phone is working perfectly beside the charging issue and so far.
Only issue is it takes 1 full day to charge it from 10% to 100%
Last night I plugged my phone at 9pm (60%). It took 8 hours to have it fully charged...
Thanks for your reply, I guess I 'll check with ATT first :'( and Motorola then....
Did you already try charging with the phone off through USB on your desktop or laptop? Maybe the wall charger is defective.
Do a backup and perform a factory restore to see if it fixes it before shipping it out for warranty.
Goodluck!

your battery and or phone is straight up defective, or something is wrong, needs to be replaced. no way should it take that long to charge. something go out of wack, and it sounds like faulty battery is failing, hence why it wont charge turned off AND takes forever to charge up when turned on.

[Q] Evo 3D doesn't turn on

Hey guys.
I have a problem with my HTC EVO 3D. I've been using it for a year and everything was fine until yesterday. I was playing Real Racing 3 when my phone suddenly restarted and then turned off before I could enter my PIN code and didn't boot up. I thought that it might have overheated or it was some crash or something, I put the phone to charging and it easily turned on (I must mention, that there were about 70% battery left). I charged my phone and didin't use it whole afternoon. In the evening, I was trying to unlock my phone (with about 70% of battery) when suddenly the same happened again - the phone restarted and before entering PIN code turned off at all. After that I wasn't able to boot my phone.
I tried charging it with original HTC AC charger and also using my laptop and even a car charger, but nothing changes.
When the phone is not plugged in to charging, it doesn't show any signs of being alive. I tried pressing volume down/up/camera buttons + power on button, taking off the battery for about an hour, charging the phone for ~6 hours. Nothing works.
However, I realised that when I connect the phone to my laptop, there is a 'new device is connected' sound, but I am not able to access my memory card or do something else. Also, when the phone is charging, the red charging light is on, which after a few hours turns to green and after some more time disappears at all. When trying to turn on the device while it is charging the red light disappears as soon as the power button is released ant comes back after about 20 seconds.
Sorry for such long story and for my bad English. I am very disappointed. I still have a warranty, but I dont want to take the phone there, because the fixing lasts at least 2-3 weeks and also since I'm unable to boot my phone, there are a lot of my personal information in it, such as passwords,messages, bookmarks and so on, left.
So, is there anything I could do or should I take my phone to service?
P.S. The phone is not rooted and never was. Everything is original and up to date.

Perhaps try a new battery or take it in and have them try one. Sounds like a battery issue.

Thanks. I took it to service. I hope they'll repair it.
I finally got my HTC back a few days ago. They changed the motherboard and I had to buy a new battery since the old one was dead and warranty for it was only a year.
But I've faced several unexpected crashes during these few days. I think 3 or maybe 4 times when I took the phone after not using it for couple of hours and tried to unlock it, the phone didn't unlock and instead turned on. I really don't like this, because if my phone turns off whenever it wants, I may be unreachable
Does anyone knows what that means and what should I do if this keeps happening?

Yes, the soft has always been and is stock.
Then it must be a hardware issue. If your warranty has not expired, take it to the warranty service.

Well as I said I dont want to take it there because it takes about three weeks or more till I get back my phone.. It would be the third time in two months and it really annoys me.
Couldn't this be software issue? I mean I've been reading some similiar threads and I found out that some app might be killing the phone. So I did hard reset yesterday and after that installed only well known essential apps (Google services and some others) and after that the phone didin't crash for almost two days. Unfortunately, it did turned off a few minutes ago. I've installed only 8 Ball Pool and Smart Keyboard Pro recently, so I will try unninstalling them both and let's hope the phone won't crash again. Is there any ideas what else may I do in case it doesn't work?

Id recommend doing a factory reset on the phone and not installing any app for at least a week to confirm its not a hardware issue, but I strongly believe it is. If it fails youll have to take it to a sprint store and hope the clerk is in a good mood and give you a new phone the same day.
try a new battery
The battery is new, I had to buy it only a week ago, because the service stated that the old one was dead.

My Galaxy View won't turn on

I've had my View since 9/16. I use it everyday for probably 6 hours or more. Every night I turn it off and plug it into the factory charger. I tried to turn it on the other day and it will not turn on. I'm a geek so I've tried everything I can find on the web and Samsung's site to get it to work. I contacted Samsung and they've sent me a label to send it back to them for their evaluation and price to fix.
A couple questions for other forum members:
1. Has this happened to anybody else?
2. Anybody had the battery die? I've put a lot of hours on mine...
3. Anybody had any experience with Samsung service?
Thanks for any feedback...
Larry
I have not had this happen to the View, but I have had it happen to a few other devices when I used to test devices for a wireless carrier. This can happen when the battery is "too dead". If the battery drops below a vital level then it can fail to start up into the charging boot screen. If it was on the charger, it's possible that your charger failed and caused a parasitic loss to the tablet. This is, perhaps, the worst problem with non-removable batteries. Sometimes you can hold the power button down while plugged in and it will start charging again. I assume you have purchased, or already have, a second charger, to rule out it being a charger issue. To have any chance of this method working, you will likely need to hold the power button for at least 10 min while attempting to charge. Basically the concept is that you are trying to get the power to flow to the battery even while it can't boot the charging screen kernel.
Thanks for your detailed reply. I really appreciate it. And I did try another charger. Didn't try holding down the power button for 10 minutes, but I get your point. I contacted Samsung and they provided a 2nd Day Air return label, which I thought was generous for a tablet out of warranty. So it's on its way to them to evaluate and give me an estimate to repair. I'll post when I hear back from them. Thanks, again, for your reply.
Samsung discovered my motherboard needed to be replaced. Cost $109 including shipping both ways and it seems to be working just fine. Of course now I have to get everything set up again. I thought the price was reasonable - a heck of a lot cheaper than a new one.

Question S23 Ultra has mysteriously died

I've had the S23 Ultra (US, unlocked, from samsung.com) for a couple of months. I didn't root it, drop it, or splash it with water. I charged it last night, but when I woke up this morning, there was no sign of life: a black screen, no sound, no reaction to charging (even after long charging with a different charger and the cable), no reaction to a long press of Power + Vol Up/Down, and nothing detected in adb.
So I have a few questions:
Has anyone else had a similar experience with their device?
Any suggestions on how I could resurrect it?
Do you have any ideas about what might happen? Throughout the two months, I used the same old low-current (850 mA) Motorolla charger. The charger is still operational.
My current plan is to contact Samsung Support.
Any advice is appreciated! Thank you!
Have you tried using a higher capacity charger, like an official Samsung charger plugged into the wall? Have you tried a wireless charging pad to rule out an issue with the USB-C port? Samsung still uses the lowest grades soldier pennies can buy on their most premium devices.

Looks like you've tried everything basic and the phone's just dead. Could be a motherboard failure. Best to go to Samsung instead of breaking your head, as it's still under warranty. At least that's what I'd do in your position.
Wish you the best.
Try half an hour charging on wireless charger if you haven't tried yet
Saw this happen on a Note 4 back in the day. It wasn't really dead but in a weird power state. Fully charging for a few hours (even though it showed nothing) then holding power and volume up and down got it to reboot.

My old Note 4 went into this state and didnt manage to revive it with Power and Volume Up + Volume Down combo. The only sign that tells me it's not fully dead is the green notification light when I do the above combo.
About weird power states - I had Galaxy Buds Pro, which refused to take any charge - wired charging did not work and wireless either. Only way to revive it was to use wireless power sharing from the phone. Problem did not reappear later. Go figure...
Really? I "didn't root it" as if that is a bad thing
You obviously charged it with faulty charger. I experienced the exact same thing. I was about to cry but then i remembered i was testing a cheap, fake Samsung charger...
Then i plugged the phone into REAL charger, waited for 2-3 minutes, phone was alive with all its glory.

Had this happen on my old s21u. Contacted support and told them I had done all the steps you did. They had me send it in for repair (was actually 2 months after warranty expired but they still agreed to repair it free of charge) and ended up changing the main board, usbc port and something else. Never happened again after (didn't change chargers or anything). So yeah, contact support that's your best bet.

It will be hard to do it if he can't even turn on the device i any way... No combination of buttons work, no way to turn it on with charger or ADB...
As its apparently either dead or in power-off state you could try to start it into download-mode by:
1. pressing Vol-Up and Vol-Down together and keep them pressed
2. plugging in a USB-cable connected to either a powered-on computer or a charger while keeping the buttons pressed
Normally it should boot into download mode (you can release the buttons after boot-up ).... Maybe this helps if the power button is broken....

Can't a power surge damage a device? It can happen either during a storm or by using a non-recommended charger. It can fry certain components, even though phones have protection.

No, it was like... My fake charger suddenly stopped working and my other phone recognized the charger + cable as a DATA TRANSFER DEVICE. It is really hard to describe the experience. No charging, my fake charger was recognized as something else..
The experience was... My S23 Ultra blacked out. I thought it was charging. Then, complete darkness. Didn't respond to power button.. Nothing. I thought it was bricked. Then i got up and found my other charger. Waited.. 10 - 15 seconds later my phone was back again. God i swear, i was shaking with sweat. It has been almost 1 month, my phone is just fine..
That day i decided to go with only geniue products. Maybe my phone protected itself by bricking itself. I really dont know.
To me it sounds like what you experienced was just an empty battery .... without juice in the battery the phone cannot do anything and the defective charger did not charge the phone while you thought it did....
Update from me: I scheduled an appointment from the Samsung site with an authorized service center (Best Buy). They checked my phone and said that they couldn't fix it if it wasn't turning on, and I had to send it to Samsung. That was unexpected.
I sent the phone to Samsung, and today I got a message that they could not reproduce the problem. I wasn't able to communicate with the service worker yet. My concern is that it could be a bad internal cable connection that restored the circuit due to the shipment vibrations. If so, and they will not check it, I could end up with a phone with a faulty connector that could die at any moment (hopefully during the warranty period).
It's also possible that being in the weird power state was fixed by simply letting the phone completely deplete of charge so that it properly turned off, recharging, then rebooting.
I had this problem on my old s7 edge. It seems that samsung never fixed this problem. The screen would stay completely black, unable to do anything until the battery completely drained. The device itself was never rooted or modified. Pretty disappointing it was never fixed.
