Monitoring battery power

TECHNICAL NOTE: It is seldom necessary to charge the RTC battery because it charges while the computer is on. However, 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.

You can use the computer while the RTC battery is being charged, although the charging status of the RTC battery cannot be monitored.

Using a battery charger

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

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 using the accessory information packaged with your computer, or through Toshiba’s Web site (www.toshibaaccessories.com).

Monitoring battery power

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

❖No illumination means the battery has completely discharged and the AC adapter is not connected.
