Really Strange About the Battery Status!
The battery status is initially red & nearly colorless. When I plug in the USB cable for charging, the battery status is showing that it is charging. But after a few minutes, it said that it is fully charged. Then I plug it off, the battery status still show me red & nearly colorless, but I can still use it for 3/2 Hours. I've tried for a few days and the situation never improve!! Could anyone tell me what is the problem?
Try using a different USB port for charging it. Perhaps 1 on the back of the computer.
The battery logic board is messed up. Replace battery.
