For information on replacing the battery, refer to Removing and Replacing the Battery on page 13. CMOS checksum error - Defaults loaded Checksum of CMOS is incorrect, so the system loads the default equipment configuration. A checksum error may indicate that CMOS has become corrupt.

Press the Tab key during POST to display messages hidden by the HP logo. Error: Non-System disk or disk error The BIOS was unable to find a suitable boot device. For the t5000 Series, this may mean an uninitialized or corrupt ATA Flash. Reflash the unit. For more information, refer to Restoring the Flash Image on page 48. Beep Codes 27
