I bought an acer Aspire V3-111P-P4KY and installed a new legit windows 8.1 to it from a USB-stick. Also installed all latest drivers acer currently provides. Anyways i dont think that has or should have anything to do with the problem. So the problem is that the orange charging light stays on and windows says "Plugged in, not charging" while it has charged only 86-94 %. The percentage varies. Iv already tried uninstalling the Microsoft ACPI-Compliant Control Method Battery driver, rebooting and pressing the tiny hole on the back of the computer to reset battery. Nothing helps.

So, does this laptop have a defective battery or what?
