Charging batteries
battery does not charge while the computer is consuming full
power.
The battery light:
Glows amber while the battery is being charged.
Glows green when the battery is fully charged.
The battery may not start charging immediately if:
The battery is extremely hot or cold. To ensure that the battery
charges to its full capacity, wait until it reaches room
temperature (50 to 80 degrees Fahrenheit, 10 to 26 degrees
Celsius).
The battery is almost completely discharged. Leave the power
connected and the battery should begin charging after a few
minutes.
HINT: Once the battery is fully charged, we recommend you
operate your computer on battery power until the battery
discharges completely. Doing this extends the life of the
battery and helps ensure accurate monitoring of battery
capacity.

Charging the RTC battery

The RTC battery provides power for the internal real-time clock
and calendar. During normal use, the battery keeps the RTC
battery adequately charged. Occasionally, the RTC battery may
lose its charge completely, especially if you have had the computer
turned off for a long time.
To recharge the RTC battery, plug in the computer and leave it on
for at least 24 hours.
