Introducing the BIOS
RTC Alarm Resume:
Two items are available: Disabled or Enabled. The default setting is Disabled. When set to Enabled, you
can set the date and time at which the RTC (real-time clock) alarm awakens the system from Suspend
mode.
" Date (of Month) / Resume Time (hh:mm:ss):
You can set the Date (month) Alarm and Time Alarm (hh:mm:ss). Any event occurring will awaken a
system that has powered down.
IRQs Activity Monitoring:
The following is a list of IRQ's, Interrupt ReQuests. When an I/O device wants to gain the attention of
the operating system, it causes an IRQ to occur. When the operating system is ready to respond to the
request, it interrupts itself and performs the service.
When one of the specified events occurs, the count down for entry into the power saving mode goes back
to zero. Since the computer will enter a power saving mode only after a specified inactivity delay (time
specific for Doze, Standby and Suspend modes) and after there has been 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.
All Interrupt Event:
Two items available: Off or Manual. The default setting is Manual. When you set this item to Manual, the
following IRQ events will be available for adjustment.
When set to Disabled, activity will neither prevent the system from going into a power management mode
nor awaken it. Each item has two options: Enabled ( Disabled.
" IRQ3 (Reserved): The default setting is Disabled.
" IRQ4 (Reserved): The default setting is Disabled.
