Disabling the Power-On Password
Before you begin:
Read “Safety Considerations” on page 4-2 and “Handling Static Sensitive
Devices” on page 4-3.
Remove the system unit cover (see “Removing the Cover” on page 4-4).
Your system unit arrives from the factory with the power-on password enabled (but
unset). You can disable the power-on password by changing the position of a jumper
on the system board.
Notes:
1. Moving the jumper to the default position re-enables the power-on password,
unless it has been removed in the System Management Services Utilities or by
removing the battery.
2. If you
forget
the power-on password, you can erase the password by shutting
down the system unit and removing the battery for at least 30 seconds. See
“Changing the Battery” on page 4-108 for details on removing the battery.
3. The system unit power cable must be disconnected before removing the battery.
To disable the power-on password, complete the following steps:
1. Remove the disk drive bracket assembly from the system unit and carefully place
it on top of the power supply. Any adapters installed in slot 5 may have to be
temporarily removed in order to remove the disk drive bracket. Refer to
“Removing Adapters” on page 4-80 for adapter removal instructions.
