Jumper

Description

In Normal mode, system setup settings and installed passwords are retained when the computer starts up. In this mode, an automatic recovery is attempted if the BIOS detects that any of its main blocks are corrupted.

Starting the computer with the jumper set in Maintenance mode automatically starts the system setup program, adds the Maintenance option to the menu bar, and displays the Maintenance screen. This screen provides the following option.

NOTICE: Entering Maintenance mode returns all settings in the system setup program to their defaults. Dell strongly recommends that you record or print all current settings before entering this mode so that you can correct them when the computer is reset to Normal mode.

Clear All Passwords — Disables a forgotten password so that you can access the computer and assign new passwords. For the complete password procedure, see "Clearing Forgotten Passwords" in the Solutions Guide.
