See "Using the System Setup Program" on page 31. 2 Turn off the system and disconnect it from the electrical outlet for at least one hour. 3 Reconnect the system to the electrical outlet and turn on the system. 4 Enter the System Setup program.

If the problem is not resolved by replacing the battery, see "Getting Help" on page 125. NOTE: Some software may cause the system time to speed up or slow down.
