initialization. Users can enable this feature to restore the BIOS firmware to a successful one once the previous

Fn+Esc
, for enable BIOS Recovery process when system is powered
on during BIOS POST. To use this function, it is strongly recommended to have the AC adapter and Battery

4.
In the power-off state, press and hold
Fn+Esc
then press the Power button.
The system powers on and the Crisis BIOS Recovery process begins.

systems.
When the Crisis flash process is finished, the system restarts with a workable BIOS.
