What to do
If system settings stored in CMOS RAM change for no apparent
reason (for example, the time of day develops an error), the backup
battery may no longer have enough power to maintain the settings.
Replace the battery (Chapter 2).
Make sure the power and signal cables for the drive are properly
installed.
Check that the drive is properly configured and enabled in Setup.
Make sure the power and signal cables for the drive are properly
installed.
Make sure the front panel connector is securely attached to the
system board headers.
Check that the drive is properly configured and enabled in Setup.
Check the drive manufacturer's manual for proper configuration for
remote hard disk drive activity.
If the system is operating normally, check the connector between the
system board and the front panel. If OK, the light may be defective.
It's probably switched off.
A serious fault may have occurred consult your dealer service
department / Technical Support.
If you can't enter Setup to make changes, check the switch that
disables entry into Setup (Chapter 2). If the switch is set to allow
entry into Setup, you might need to clear CMOS RAM to the default
values and reconfigure the system in Setup.
This indicates a fatal system error that requires immediate service
attention. Note the screen display and write down any beep code
emitted. Provide this information to your dealer service department /
Technical Support.
