System Wake-Up Setup from Separate Device. Part I

When a computer is in one of power saving modes or is off, there is an opportunity to turn it on after some events, for example, after receiving the modem signal or after pressing a particular button. There are usually the parameters which may be located directly in a section “Power Management Setup” or in a separate subsection “Wake Up Events”.

This subsection usually contains settings for switching on or wakening up the computer from separate devices. For the value “Enabled (On)”, a device is allowed to turn on a computer, and for the value “Disabled (Off)” this action is not allowed. Each model of motherboards has its own set of parameters and their functions will be the following:

  • VGA – allows removing a computer from the power saving mode if a video adapter is active;
  • HDD&FDD – the value On will remove a computer from the power saving mode if a controller of floppy or hard disks is active;
  • LPT&COM – enabled wakening up the computer if a parallel (LPT) or serial (COM) port is active;
  • PCI Master – the value On will remove a computer from the power saving mode if some PCI-device is active;
  • Primary INTR – the value On will remove a computer from the power saving mode if the primary controller of interruptions is active;
  • PowerOn by Ring (Modem Ring On, Resume On Ring) – allows turning a computer on with internal modem ring;
  • Resume by Alarm (Power On By RTC Alarm, RTC Alarm Resume) – allows automatically turning a computer on at scheduled time. Use additional parameters to set the time: Date (Of Month) and Resume Time (hh:mm:ss) or similar to them.
