Awakening by a Signal of Internal Devices. Part I

To block the transition to the power saving mode, you can use the parameters that monitor the state of such devices as video card, hard disk and others. This might be necessary, for example, while displaying or printing of a large amount of data, the hard disk testing or implementing the other automatically-executing programs. Here is a list of parameters which monitor a state of devices and block the transition to the power saving mode:

  • A parameter “VGA Active Monitor” (Wake Up Events VGA) enables to wake up a computer if its video card is active. It has two parameters: On and Off. It is better to switch this parameter on.
  • A parameter “LPT & COM” (Wake Up Events LPT&COM) enables to wake up a computer it its serial or parallel port is active. It has got two values: On and Off. Enabling this parameter allows, for example, preventing falling asleep while printing large documents.
  • A parameter “HDD & FDD” (Wake Up Events HDD&FDD) enables to wake up a computer if its hard disk is active or during operation of its floppy-disk. It has got two values: On and Off. This parameter should be turned on to prevent entering the power saving mode by a hard disk. To monitor the hard disks, you may use the parameters “Primary Master IDE”, “Primary Slave IDE”, “Secondary Master IDE” and “Secondary Slave IDE”. Each of these parameters monitors the activity of a device connected to an appropriate connector on IDE-loop. Use a value “Monitor” for these parameters that enables to monitor a device state and, in case of its activeness, to prevent entering the power saving mode.
