Using BIOS
Power Management Setup
This option lets you control system power management. The system has various power-
saving modes including powering down the hard disk, turning off the video, suspending to
RAM, and software power down that allows the system to be automatically resumed by
certain events.
The power-saving modes can be controlled by timeouts. If the system is inactive for a time,
the timeouts begin counting. If the inactivity continues so that the timeout period elapses,
the system enters a power-saving mode. If any item in the list of Reload Global Timer
Events is Enabled, then any activity on that item will reset the timeout counters to zero.
If the system is suspended or has been powered down by software, it can be resumed by a
wake up call that is generated by incoming traffic to a modem, a LAN card, a PCI card,
or a fixed alarm on the system realtime clock.

If you want an incoming call on a modem to automatically resume the system from a power-

connector for this feature to work.
