Doesn’t charge
The charging time when the computer is on is affected by ambient
temperature, the temperature of the computer and how you use the
computer. If you make heavy use of external devices, for example, the
battery might scarcely charge at all during operation. Refer also to the
section
Maximizing battery operating time
Leaving the AC adaptor connected will shorten battery life. At least once a
month, run the computer on battery power until the battery is fully
discharged, then recharge the battery.
