Setting Power Saving Timers - IBM Aptiva Series Hardware Maintenance

ECP DMA Channel
This item becomes active only if you select ECP as the operation mode. It
allows you to select DMA channel 1 or DMA channel 3 depending on the
available system resource.
NumLock after boot
This parameter displays whether the NumLock function on the keyboard turns
on automatically each time you turn your computer on. You can set this to
Enabled or Disabled. The default is Enabled.

Setting Power Saving Timers

The system power management feature allows you to reduce power
consumption. When the Power Management Mode parameter is set to
Enabled, you can configure the different power saving timers to your desired
settings. Setting this parameter to Disabled deactivates the power
management feature and all the timers.
Monitor power saving timer
This timer allows the monitor to enter suspend mode after the number of
minutes that you specified has elapsed. Any keyboard or mouse action, or a
video buffer access, returns the monitor to normal operation. Press the left or
right arrow key to select your desired setting. Setting this timer to Off
deactivates the monitor power saving function. The default setting is 15
minutes.
Set this timer to Off if you want to use the monitor energy saving feature in
Windows 95.
IDE hard disk standby timer
This parameter allows the hard disk to enter standby mode after inactivity of 1
to 15 minutes, depending on your setting. When you access the hard disk
again, allow 3 to 5 seconds (depending on the hard disk) for the system to
recover and return to normal speed. Set this parameter to Off if your hard disk
does not support this function.
System standby timer
This parameter sets the system to a "fast-on" power saving mode. It
automatically enters the standby mode after a period of inactivity. Any
keyboard or mouse activity, or any enabled monitored activities occurring in
the IRQ/DMA channels resume system operation.
Press the left or right arrow key to select your desired setting. Setting this to
Off disables the timer.
