My Acer R11 R131T won’t charge, or power on without being plugged in, but tells me the battery is there and gives me a percent. It says “40%, Plugged in, not charging” at the moment, but it’s been going down slowly. I’ve tried the power reset by pressing the button on the bottom and waiting a few minutes (overnight). I’ve also tried other chargers, including new chargers. Any tips or help would be nice. Thank you!

There was a button that is inside the computer that needs to be pressed down. I drilled a hole in the laptop, and taped a screw in it to hold the button in place.

The battery has got to be the prime suspect. As for the 40%, it’s clearly having you on. You could try running BatteryInfoView from Nirsoft.net, which gives more detailed information, but it doesn’t have a battery lie detector.

Sounds like a battery problem to me, so let’s try a new battery. I included a link to get a replacement battery and a guide on how to replace the battery. Battery Replacement Acer Aspire R11 R3-131T-C1Z5 Battery Replacement
