This will only work if your computer supports this. For this, both your BIOS and &os2; must support at least APM V1.1, or you must have installed ACPI support. The APM and ACPI levels of your system are displayed on the shutdown notebook page for your convenience.
If the "Delay" setting is also enabled, &xshutdown; will wait three seconds
before actually issuing the power-off request to the APM.SYS driver or
ACPI subsystem.
This might help on a few systems where the power was switched off before all the
caches were flushed. If you get CHKDSK's after using power-off, you might want
to try enabling this setting.
