1. If the system is in S0, S1 or S2 state, pressing the power button will transit the
system to S4 (Suspend to Disk) or S5 (Soft-off) state depending on the “Power
button function” setting in the BIOS Setup menu.
2. If the system is in S4 or S5 states, pressing the power button will awaken the system
into S0 states.
3. If the power button is pressed for more than four seconds, a power button over-ride
event is generated and the system will be put into S5 (Soft-off) state.
2.2.2 Cover (Lid) Switch
When LCD cover is closed, this Lid switch is triggered and an SMI/SCI is generated to
put the system into ‘Suspend to RAM’ or ‘Suspend to Disk’ mode depending on the
“Cover Switch” setting in the BIOS Setup menu.
2.2.3 Quick Start Button
When this button has been pressed, the system will launch either Microsoft Internet
