Clearing the Password
If the password needs to be cleared and reset, set jumper block 7F4 as follows.
Jumpers are set correctly at the factory for the system
configuration. Only change (or check) the appropriate
jumper setting if you forgot your password or want to change
the password.
1.
Power off, unplug the system power cord, and disconnect any peripherals.
The system power must be off before opening the system
and changing a jumper setting.
2. Remove the SO-DIMM panel on the bottom of the system unit (see
“SO-DIMM Module Removal” in Section 3 for procedures).
3.
Locate jumper block 7F4 between the two SO-DIMM module slots (see the
figure “System Board Connector, Socket, and Jumper Locations - Side 1”
earlier in this section).
4.
Remove the jumper from pins 1 and 2 to clear the password settings.
5.
Replace the jumper on pins 1 and 2.
6. Replace the SO-DIMM panel.
7. Connect system power cables and external devices.
8. Power on the system.
9. Run the BIOS Setup utility to set a new password (see Section 2).
Processor Socket
The processor installs in a 370-pin Socket370 on the system board. The
processor is held in place in the socket by a locking lever attached to the socket
and a removable retention clip. The retention clip anchors both the processor
and the processor heatsink to the Socket370.
To remove or install a processor, see Section 3, “Disassembly and Reassembly.”
