Buttons
Power Button
Under ACPI, the power button action is under the control of the operation system.
•
The following is a table of the state transitions in ACPI mode.
Initial Final Comments
Off On Does a normal reboot. Prompts for password if required.
Standby On Restores device states from RAM. Prompts for password if required.
Hibernate On Restores RAM and device states from disk. Prompts for password if
required.
On Standby,
Hibernate(
default) or
Off
. Action depends on OS setting. Can be set to Standby, Hibernate, or
Off(default).
. Note that the Off option is done under the control of the OS, so it is
functionally the same as doing a Start-Shut down but probably quicker.
Power Button Over-ride
Holding down the Power Button for 4 seconds will cause an unconditional transfer to the Off
state without notifying the operating system.
If press power button for less than 4 seconds, the system will enter suspend to RAM or OFF
state according to OS UI setting.
Lid Switch
This section describes the expected behavior of the system when the lid is opened or closed
by the user.
If the system is running under legacy mode:
•
Closing the lid will turn off LCD backlight.
If the system is running under ACPI mode:
•
The function of lid switch will follow the OS setting in power management (Nothing,
standby, Hibernate or Power off). If standby, the system wakes up when the lid opens. If
nothing, the backlight must still turn off when the lid is closed.
System status indicators
Please refer to Keyboard BIOS specification.
