Note: If you forget the power-on password, the battery must be removed for longer
than 30 seconds to reset the NVRAM, contact your service representative.
Attention: After you remove the battery, you must reconfigure your system (bootlist,

A password can be set only after the system is turned off and on again.
Remote Mode: The remote mode, when enabled, allows the system to start from

If you remove the power-on password, the remote mode is automatically reset, and
the icon returns to Remote <Off>.
