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.
