Monitoring main battery power

To recharge the RTC battery, plug in the computer and leave it turned off for at least 24 hours.

TECHNICAL NOTE: It is seldom necessary to charge the RTC battery because it charges while the computer is on. If the RTC battery is low, the real-time clock and calendar become slow or stop working.

When Hibernation mode is enabled and the RTC battery is completely discharged, a warning prompts you to reset the real- time clock.

Using a battery charger

You can purchase an optional battery charger that recharges lithium polymer battery packs without requiring the use of your computer.

Use the battery charger to charge the optional high-capacity battery and to charge spare main battery packs.

CAUTION: Avoid leaving batteries in the battery charger for more than a week at a time. Doing so may reduce the potential charge of the battery.

Use only battery chargers designed to work with your computer and its batteries. You can order a Toshiba battery charger through the accessories information sheet or Toshiba’s Web site at toshibaaccessories.com.

Monitoring main battery power

The computer’s main battery light gives you an indication of the main battery’s current charge:

❖No illumination means the main battery is not in use and the AC Adapter is not connected.
