My Pavilion dv7-3163cl just started shutting down unexpectedly. It has happened 3 times now and never while I'm using it and always as it sits plugged into the AC power. The only way I can get it to turn back on is by removing the battery and reinstalling it. Why is this happening? The battery life is fine and the charging is fine. Thanks!

It is probably going into "sleep mode" if you are letting it sit idle for several minutes. You should be able to have it re-start by rubbing your finger around on the touch pad a few times.

No, that's not the problem at all. It actually turns off completely and pressing the power button doesn't even bring it back. I have to take out the battery and reinstall it for it to turn on.

Update to my troubleshooting... the symptom does not show up if I leave the laptop in hibernate mode and NOT plugged in to the power cord. It comes back every time but if I leave it with the power cord plugged in, even in hibernate mode, it will eventually turn off and can't be turned on again without removing the battery and then putting the battery back in. Any suggestions?

So, apparently, the battery is not the problem since it maintains the computer if the power cord is not connected.
Try testing the power converter with a voltage meter and see if it is putting out the proper voltage. If it tests out ok then try running the computer without the battery in. As soon as it shuts down test the converter again to see if it is still supplying the proper voltage. Maybe it shorts itself out when it warms up. If the converter tests ok in both instances then it must be something from the power port in that is stopping power to the cpu.

I suspect you are right-on with your analysis. Unfortunately, I'm not tech savy to check the voltage so what I'm doing is keeping it unplugged unless I need to charge the battery. If this becomes a problem, I will find someone that can check the voltage as you suggested. Thank you for your help!
