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.

If the following message is displayed on the LCD:

The charge in the RTC battery is getting low or has been exhausted. You

will need to set the date and time within the BIOS setup using the following

steps:

1. Press F2 key - the BIOS setup screen will be displayed.

2. Set the date in System Date.

3. Set the time in System Time.

4. Press F10 key. A confirmation message will appear.

5. Press Enter key. BIOS setup will terminate and the computer will be

rebooted.

The computer's RTC battery is a lithium ion battery and should be

replaced only by your dealer or by a TOSHIBA service representative. The

battery can explode if not properly replaced, used, handled or disposed of.

Dispose of the battery as required by local ordinances or regulations.
