IMPORTANT:
All BIOS configuration settings will be
lost when the backup battery is removed!
ATTENTION:
Be careful when removing the backup
battery. If the metal lever is damaged or
broken, the system board must be replaced.
Gently pull the metal lever away from the backup
battery.

IMPORTANT:
Make sure to insert the battery with the

date and time in the Configuration/Setup Utility,
select the Date and Time option from the Main
