Nexus 7 (2013) will not stay on

[debsawyer]

I have used a wireless charging pad for my tablet for the past year or longer. The tablet stays on the charging pad until I need to use it, and it goes back on after I use it. I noticed I had not heard any notifications for a few days. I check the device, and it was powered down, but still on the wireless charging pad. I used my original charging cable, and the device came alive. The tablet only stays on when it is plugged in. When I unplug it to, and click on a few apps it just shuts down with no warning. I called Asus, and they said that the board may need to be replaced. They want $200, no way. What do you suggest I do to troubleshoot the device? I have already reset the device, but no change. I am not paying to get it repaired. I just hope Google comes out with another Nexus tablet because this was my favorite.

So it powers on and then randomly turns off? And survives a factory reset. That means it's probably hardware. I opened up the back on mine a couple weeks ago, unplugged the battery from the board and reseated the gold ribbon that goes down the center. Takes about 5 minutes and has a good chance of helping if you feel comfortable doing that. It's pretty easy to do, definitely not worth $200.

It sounds more like a bad battery to me, if it won't stay on long without being plugged in.

I'd agree with the battery as the culprit - sounds like it's shot.

I haven't looked at replacement cost for the battery, but if it's anywhere close to $100 you'd be better off investing that in a brand new nVidia Shield K1 - at $199 it's the top performer in the price range.

The battery is fully charged. There is no issue with the battery. It just will not stay powered on.

Thanks. I will try that.

Photo is not mine; I just added circles.

If you're comfy working under the hood: Red circle is the battery connection to the board. It pries straight up. The purple circle is the ribbon I mentioned. On mine, under the tape in the purple circle, the connection was loose. Lifting the tape, re-seating that ribbon connection might fix the issue, but disconnect the battery wire first and then remember to re-seat it as well.

If you leave the tablet plugged in will it operate normally as long as it's connected? If so, that's a classic symptom of a battery that's lost its ability to hold a charge, regardless of what it reports about the charge level.

Guess you'll find out when you open it up.

Could your sleep setting have gone miss set?

Go to settings > Display > Sleep and see if it's set too low.

Okay I removed it from the case, and removed the connectors from above, and reconnected everything back. I suppose it's either a bad battery or motherboard (according to Asus). The tablet still boots up, and shuts down shortly after. I am also thinking that maybe I killed the battery by charging it all the time on the wireless charging pad. Well this was my favorite tablet (I also have the Nexus 2012). I hope Google has another Nexus tablet sometime in the near future. Thanks everyone for all of your help
