I have recently started seeing this pop-up message - 'For full performance, connect a higher capacity AC adapter'. It shows up when I plug in the AC adapter, but, not every time. The message is in a small blue box w/ a rocket in the corner.
The computer's battery meter shows that it charges to 100% and stops charging.
What else does it need?
Laptop is a G60-535DX with Windows 7. AC adapter is standard 65 watt that came w/ computer new.
