1.2 Resetting the Computer

If the computer you are servicing has an unknown password,

follow the steps below to reset the password. These steps also

clear CMOS.

✎The following steps will not clear an unknown password if the

to reset an unknown password. Refer to Section 5.13, “RTC

Battery,” for more information on replacing the system board.

Before replacing the system board, perform the steps below to be

by accessing the Password Options menu in the Computer Setup

utility. Refer to Section 2.1, “Computer Setup,” for more

information.

on removing and replacing the RTC battery).

2. Wait approximately 5 minutes.

3. Replace the RTC battery and reassemble the computer.
