Resume events for zero-volt suspend(suspend-to-disk)
The only resume event for zero-volt suspend is the raising of the lid of the computer. This
electronically enables the power to the rest of the machine.
Resume events for static suspend (suspend-to-memory)
1.

Resume on schedule.

In BIOS Setup, this time field can be enabled then set to any
value. It is possible to set it for a date and time in the past. In this case, the unit will
resume at the next occurrence of the specified time, date ignorant. If a proper future
date is specif ied, then the res um e will only happen long enough to evaluate the date and
the mac hine will re-sus pend. After a s ucces sf ul resum e has tak en place, the resum e on
schedule f ield will autom atically disable. . Enabling of this field will disable the suspend-
to-disk func tion, except f or battery very low. The auto-disable of res ume on sc hedule s till
allows the unit to suspend to disk at the next occ urrence of a suspend c ondition with the
lid closed.
2.

Lid switch.

If the sus pend-to-disk option is used, then the lid switch will turn the unit on,
reboot and then resume to the application at the end of POST. If the suspend-to-
memory option is in place, or a suspend-to-disk block is present, then the lid switch
opening will resume the machine.
3.

Keystroke.

Any key use on the internal keyboard will wake up the system from static
suspend. In addition, a keystroke from an external keyboard on the primary PS/2 port
will also wake the system up. Mouse m otion from any source will not wake the system
up.
4.

Battery very low.

The SMC will wake the SMI if the batter y reac hes a ver y low c ondition
during static suspend.
