A2-5 Power Off Mode of Front Power Switch Process Sequence
If APM BIOS is in use for the BIOS, Suspend event is sent to OS from BIOS and the BIOS forcibly
turns off the power. Therefore, it operates as if it is in Power Off status when it tutns into the
Suspend mode in Windows 95/98.
If the main power switch is pressed during the Suspend mode, it turns to resume event and
follows “Resume from the Suspend Sequence”(appendix 2-5).
Also, it does not recognize wheather or not the Video is off, therefore it forcibly changes its
status to power off.
If the system hungs in this mode and cannot turn off the power, kept pressing the switch for
more than 4 seconds and the hardware(Chipset) turns off the power.
