HP and Compaq Desktop PCs - Error: CMOS Checksum Bad

This document pertains to all HP and Compaq Desktop Computers.
One of the following error messages appears when starting the computer:
  • BIOS ROM checksum error
  • System CMOS checksum bad - default configuration used
    Press <F1> to resume, <F2> to Setup
  • CMOS Checksum Bad
    Press F2 to Run SETUP
    Press F1 to load default values and continue
  • CMOS Checksum Error - Default loaded
The error that appears depends on the type of BIOS used. Any of these error conditions indicate that a Basic Input/Output System (BIOS) test failed.
There are two main reasons why a BIOS test fails:
  • The battery on the motherboard has lost its ability to supply power. The system time and date are also affected by a bad battery.
  • The BIOS was updated "incorrectly". This can happen if power is lost while updating the BIOS, or when the BIOS is updated with an update that was not downloaded from HP, or when a certain virus or malicious program modifies the BIOS data.
To resolve the error, use one of the following sections.
Click the applicable BIOS version or the accompanying plus (+) sign to expand the information.
