I got an answer to my problem with my Samsung Galaxy GT-N5110. Replacing the battery with a new didn't solve it. I later removed all key pads (power, vol+, vol-). It started working well somehow. I then checked the flex the power, vol+ and vol- were sitting on. The power pad was weak and broken. Because of this the power button was permanently On. This was confusing the Tablet which made it to recycle the power On. Solution: I changed the flex that control the power, vol+and vol-. It's a single flex which I bought online. This solved the problem. For about five months now the Tablet has been working as before. Pls check that flex and replace it. Hoping that there is no other physical damage on other ports. Pls note-if you're not a Tech man like me don't try it. You may damage other tiny components on the board. Let a Tech man help you to fix this.

My lovely galaxy note 8.0 is no more lovely. It happened yesterday when I power up but could booth through. It has served me faithfully since Sept, 2014. I shutdown it down Tuesday night but could come not on yesterday when powered. It was about 80% battery when I shutdown. But surprisingly I met it warm the following morning while it is still off. When I power on it showed 24% battery and about 1 minute it shutdown by itself and then it never booth completely again. It stopped at “Samsung GALAXY Note 8.0” screen and keeps displaying it every 4sec. I opened it the first time today to disconnect the battery and back as been suggested, but the same thing. Is that the end of my note 8.0? Can a Tablet be programmed to kill itself after some years of use? Pls is there any other thing to do to bring it back?
