password prompt appears on the screen each time the computer is powered on.
The computer starts after the proper password is entered.

the computer and use the following procedure.
Note: This also erases the date and time.
Note: On some models, this procedure will also remove the administrator password.
1. Unplug the power cord and remove the top cover.
2. Refer to “Identifying parts on the system board - small desktop model” on
page 27 to find the Virtual clear CMOS/BIOS recovery jumper.
