Sony Xperia Tablet powers itself off.. advice please!

[fee.666]

Hi! 

Bought a 32gb Xperia Tablet S last Monday and am happy with it.   I have this issue at the moment and would appreciate any advice.

If I do not use the tablet for a time, it goes into a 'standby mode' and I can touch the power switch to wake it up.  I then slide the unlock icon to make all active again. 

However, after a period of non-use, my tablet switches off completely and I have to reboot and can see the SONY screen and then XPERIA screen, before it boots and is ready to use. 

Occasionally this reboot happens within 5 minutes of being in sleep mode.:smileycry:

In Settings -> Display,  I have set the Power save mode as checked,  and Sleep is after 2 minutes.  Also in Settings, Developers options, stay awake is checked but I know this relates to when the tablet is being charged

Please can you advise me if there is any settings that I need to change or if I have been unlucky and have a faulty tablet and will need to return it to the Sony Store!

I was told that the tablet has an 'Eco Mode'  but that does not make sense because powering off means no mail check etc etc!

I think that the Wi-Fi in the Sony Xperia T mobile phone are much better as options. 

If the forum at XDA Developers is read  - http://forum.xda-developers.com/showthread.php?t=1904445&page=4

A member there called Fluxman has posted a log of running processes.  I have attached this log to this email.

Part of this log shows

10-01 11:07:29.150 I/wpa_supplicant(  718): wlan0: CTRL-EVENT-DISCONNECTED bssid=00:23:69:73:b9:d2 reason=1024

10-01 11:07:29.170 D/ConnectivityService(  215): resetConnections(wlan0, 3)

Why are all IP addresses cleared on wlano?  Then there is an attempt to change to Bluetooth Tether....

I do hope this issue can be resolved quickly...

I'd also like to chime in with the same issue.

It generally happens about twice a day and although it's more of a minor inconvenience,

it's perplexing nontheless.

It would be great to see Sony resolve this issue as quickly as they did with the wifi issue

as it spoils an otherwise great tablet(just so long as you don't get it wet, he he).

Hi  Jharlow,

welcome to Questions & Answers..:smileyhappy:

Thanks for the post, as you may have noticed Sony are aware of the problem but unfortunately no news on a fix as yet yet..

jharlow!

I think you sould also call 08702402408 and when  promoted for a 7 digit case number just type 1234567#

You will then get through to an operator and you can register your problem and receive a CASE NUMBER!

I would also tell them the answrs to these questions,

- Have you installed any Apps / SW that may cause this issue.
- Make sure no external devices connected.
- Does the tablet switch to sleep automatically or when you press the power button.
- Make sure that no disconnect policy option in the advanced wireless settings.

Good luck!

You didn't get it wet did you? I had an Xperia tablet, and it started turning itself off after getting the screen wet...

[fee.666]

No, I didn't get it wet..

I received a phone call from Sony last night and was asked if I had upgraded to the latest version of the OS..

I had told that, 4 times, when  I registered the problem with Sony....  I was promised a call back for next week,,

Whilst I was talking my tablet switched itself off!  :smileyblush:

yes I have the same problem. randomly shuts itself down once in sleep mode. I'm on the most up to date android level that was released a week or so ago. I have an sd card in the device and have not tested the behaviour without it in place. May stay powered on for up to an hour but may power down after 5 mins in sleep mode. Had one instance where it crashed and re-booted while using skype to make a video call. I am seriously regretting not getting the ipad.

Sony, cop on and sort this crap out. This is unacceptable. If I put it to sleep I want it to sleep. If I want to shut it down I will explicitly request it to shut down.

Please figure out the the bug and release the fix promptly. Most units seem to be having the problem so I would expect the fix soon as it is easily re-creatable.

took out sd card this morning and left it a good 3 hours + .

when I tried it, it woke up from sleep mode. it had not powered off. seems to be the sd card causes my issue. I require to leave the sd card in though so this needs to be fixed. it is difficult to move the card in and out (intentionally so because of splashproof design point) so behaving normally with sd card in place must be catered for .
