Introduction of BIOS 3-25
Standby Mode:
When the setting selected for "Power Management" is "User Define", you can
define for this mode any delay from 1 minute to 1 hour. If no power
management event occurs during this time period, meaning the computer is
inactive during this period, the system will enter the
Standby power saving
mode.
If this mode is disabled, the system will enter the next mode in the sequence
(Suspend mode).
Suspend Mode:
When the setting selected for "Power Management" is "User Define", you can
define for this mode any delay from 1 minute to 1 hour. If no power
management event occurs during this time period, meaning the computer is
inactive during this period, the system will enter the
Suspend power saving
mode. The CPU stops working completely.
If this mode is disabled, the system will not enter the Suspend mode.
Wake-Up Events:
When system is in Doze or Standby power saving mode, it will check for the
wake-up events (IRQ4, 3, 8, 12) defined. When it detects an activity of one of
the IRQs defined, it exits the power saving mode and returns to full operation
mode (Normal).
Wake-up events are all operations or signals that cause the system to recover
normal operation.
Power Down & Resume Events:
When one of the power down and resume events (IRQ3-15) speficied occurs,
the count down made for entry in power saving mode goes back to zero.
Since the computer will enter a power saving mode only after an inactivity delay
specified (time speficied for Doze, Standby and Suspend modes) and after it has
no activity, during this time period, any event will cause the computer to
re-count the time elapsed. Resume events are operations or signals that cause
the computer to resume time counting.
