Xperia Z4 Tablet keeps turning off on its own

I found my tablet turned off in the morning several times in a row.

I could not turn it on by pressing the power button. When I pressed volume buttons and the power button together however, it vibrated three times and switched on.

The battery was well over 60%. It worked fine for the day. But it would repeat the same problem next morning despite being fully charged before bed.

I always used the alarm clock function, so it got pretty annoying.


Additionally the tablet would switch off its display in the middle of watching videos or browsing the internet, especially when I am holding it facing down.

I can turn it back on by pressing the power button, but it happens way too often to use the tablet on bed.


I've been using it for about 3 - 4 month.

I disabled some of the default apps that I do not use when I first got the tablet.

Other than that I have not meddled with any system functionality.

The problem started about a week ago.

Nexus 7 keeps turning on by itself

I have the Nexus 7 2013 model. I don't know what I did wrong. I replaced the battery yesterday and now the tablet randomly turns on every few seconds. I removed the back cover and it still turns on randomly. I re-seated the film connectors and the battery connector. I also did a factory reset and that did not help.

I can put light pressure on the power switch and it won't turn on. It needs a good solid press to turn the Nexus on.

That's it from then I'm unable to turn on my phone , iv tried holding volume down and power button for more than 60 secs still no progress.....when plugged it after intervals of time it vibrates 5 times by itself (LED is orange not blinking just on) kindly help guys...:confused:
