Power and Power-Up Modes Battery types The computer has two types of batteries: ■ Battery pack ■ Real Time Clock (RTC) battery Battery pack When the AC adapter is not connected, the computer's main power source is a removable lithium ion battery pack, also referred to in this manual as the battery. You can purchase additional battery packs for extended use of the computer away from an AC power source. The battery is a disposable item. When its operation becomes short even when fully charged, replace it with a new one. ■ The battery pack is a lithium ion battery, which can explode if not properly replaced, used, handled or disposed of. Dispose of the battery as required by local ordinances or regulations. Use only batteries recommended by TOSHIBA as replacements. ■ Do not remove the battery pack while the computer is in Standby Mode. In this mode data is stored in memory, so if the computer loses power, it will be lost. ■ Battery type (depending on the model you purchased): 6 cell-PA3399U-2BAS, PA3399U-2BRS 9 cell-PA3478U-1BAS, PA3478U-1BRS 12 cell-PA3400U-1BAS, PA3400U-1BRS Real Time Clock battery The Real Time Clock (RTC) battery provides power for the internal real time clock and calendar. It also maintains the system configuration. If the RTC battery becomes completely discharged, the system loses this data and the real time clock and calendar stop working.

The computer's RTC battery is a lithium battery and should be replaced only by your dealer or by a TOSHIBA service representative.
