Chapter 5 System Troubleshooting
Clear the CMOS If the system configuration has been corrupted, an incorrect setting has caused
error messages to be unreadable, or you cannot access the BIOS set-up utility to
load the system defaults, you must clear the system configuration values stored in
the CMOS.
Follow these steps to clear the CMOS.
1. Back up all system data and then shut down the computer.
2. Follow the steps for Pre-configuration on page 30 .
3. Remove the cover as detailed in Remove the Bottom Plate on page 31 .
4. Locate the CMOS jumper on the
motherboard.
See Figure 7 on page 20 or Figure 8 on
page 21 for where the CMOS jumper is on
the motherboard.
5. Remove the jumper block from its default
position (over pins 1 and 2).
6. Place the jumper block over pins 2 and 3
for 10 seconds.
7. Return the jumper block to its default position.
8. Reinstall the cover as detailed in Reinstall the Bottom Plate on page 32 .
9. Follow the steps for Post-configuration on page 31 .
10. During POST, press F2 to access the BIOS set-up utility and reconfigure
settings.
Ship or Transport the
Computer If you need to ship the computer via common carrier or otherwise transport it to
another location for servicing or any other reason, you must first uninstall the
computer and place it in its original packing material.
IMPORTANT The jumper block must be returned to its default position over pins 1
and 2. The computer does not start if you leave the jumper block over
pins 2 and 3.
IMPORTANT When you clear the CMOS, all BIOS settings return to their defaults.
BIOS settings other than default must be reconfigured after clearing
the CMOS.
