2.2 Mechanical Buttons and Switch Definition
2.2.1 Power on/off button 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 `Standby Mode' or `Suspend to Disk' mode depending on the "Cover Switch" setting in the BIOS Setup menu. 2.2.3 Hot Function Button When this button is pressed, the system will launch Microsoft Internet Explorer and connect to Uniwill's Web Site.
