So, I've just got my new Asus GL552JX and was really happy about it. Thought there were no problems with it. But now, I've used it for 24 days and the battery is saying "99% Available (Plugged in, Not charging)." I tried removing the AC adapter. If I leave the adapter plugged in, the battery doesn't go down. But if I unplug it, the bettery starts to go down. When I re-plug it, the battery says "98% Available (Plugged in, Not charging)" and the baterry just refuses to go up, even when I left it over the night wich is about 8 hours.
I also tried uninstalling the battery and unplug the computer, turning it off, plug in the adapter, turn it on, uninstall the Microsoft ACPI-Compliant Control Method Battery. After that, I scanned for drivers and it automatically reinstalled.
Note: I am running Windows 8.1 Pro
