I just repaired a ASUS 1015PE, I replaced the monitor. After putting it back together the laptop everything works just fine.
In the taskbar it says 0% available (connected to ac, accu is being charged). I left it on for 24 hours, it still is charging. I removed / updated everything in device manager that could be related to the battery.
Also tried a Yanec netbook adapter, but still it has the same problem.
Still got to set the date and time, but it would be ridiculous if this would be related in any way.
