PM Timers
The following four modes are Green PC power saving functions which are only user configurable when User Defined Power Management has been selected. See above for available selections.
HDD Off After
By default, this item is Disabled, meaning that no matter the mode the rest of the system, the hard drive will remain ready. Otherwise, you have a range of choices from 1 to 15 minutes or Suspend. This means that you can elect to have your hard disk drive be turned off after a selected number of minutes or when the rest of the system goes into a Suspend mode.
Doze Mode
When enabled and after the set time of system inactivity, the CPU clock will run at slower speed while all other devices still operate at full speed.
Standby Mode
When enabled and after the set time of system inactivity, the fixed disk drive and the video would be shut off while all other devices still operate at full speed.
Suspend Mode
When enabled and after the set time of system inactivity, all devices except the CPU will be shut off.
PM Events
You may disable activity monitoring of some common I/O events and interrupt requests so they do not wake up the system. The default
When On (or named, in the case of LPT & COM), any activity from one of the listed system peripheral devices or IRQs wakes up the system.
HDD Ports Activity
When set to On (default), any event occurring at a HDD (serial) port will awaken a system which has been powered down.
COM Port Activity
When set to On (default), any event occurring at a hard or floppy drive port will awaken a system which has been powered down.
LPT Port Activity
When set to On (default), any event occurring at a LPT (printer) port will awaken a system which has been powered down.
VGA Activity
When set to On (default), any event occurring at VGA will awaken a system which has been powered down.
IRQ [ 3-7, 9-15], NMI
The following is a list of IRQ's, Interrupt ReQuests, which can be exempted much as the COM ports and LPT ports above can. When an I/O device wants to gain the attention of the operating system, it signals this by causing an IRQ to occur. When the operating system is ready to respond to the request, it interrupts itself and performs the service. As above, the choices are On and Off. When set On, activity will neither prevent the system from going into a power management mode nor awaken it.
IRQ 8 Break Suspend
You can Enable or Disable monitoring of IRQ8 (the Real Time Clock) so it does not awaken the system from Suspend mode.
