If the system is in S0, S1 or S2 state, pressing the power button will transit the system to S4 (Suspend to Disk), 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 state, pressing the power button will awaken the system into S0 state. 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 WWW function button 340S2 22 Rev : B Chapter 4 System Disassembly When this button is pressed, the system will launch Microsoft Internet Explorer and connect to default setting of Internet Explorer. 2.2.4 CPU DIP Switch Settings (SW7 – near CPU socket) SW7 (For Celeron and Pentium III) 1 234 CPU SDRAM ON OFF OFF OFF 66M 66M OFF OFF OFF OFF 66M 100M OFF OFF OFF ON 100M 100M Note: SW7-5, 6, 7, 8: Always OFF Processor Celeron L2 Cache Size(Kbytes) 500 128 533 System Bus Frequency(MHz) 128 566 66 128 600 66 128 66 66 Processor Pentium III L2 Cache Size(Kbytes) 500 256 550E System Bus Frequency(MHz) 256 600E 100 256 650 100 256 700 100 256 750 100 256 800 100 256 850 100 256 100 100 340S2 23 Rev : B Chapter 4 System Disassembly 2.3.
