Power Switch Function Selects whether the power switch turns the notebook on
and off (the default), or makes the notebook enter the suspend mode and resume
from it.
Power Management Allows you to enable or disable power management. When
this option is Disabled, all power management settings specified are ignored. When
set to AC Disabled (the default), power management is disabled only when the
notebook is powered by AC.
CPU Performance Specifies the CPU performance. High refers to normal
performance. Selecting Low reduces the CPU performance and thus saves power; as

a result, system operation will also slow down.
Hard Disk Power Down after Allows you to specify a period of inactivity after
which the hard disk drive is shut down. Possible values include Disabled, 1 2, 4, 8,
or 16 min (default is 1 min). When the specified time elapses without accessing the
drive, the drive turns off. You will notice a slight delay when a resume event occurs,
while the hard disk drive powers back up.
LCD Backlight Allows you to select the brightness of the LCD Backlight. Possible
values include Bright, Standard, or Dim.
Suspend Mode Allows you to select when a suspend event occurs, Suspend to RAM
(the default) or Suspend to Disk. The exceptions are: the notebook suspends to RAM
for cover switch event and suspends to disk for critical battery event.
Auto Suspend Allows you to specify a period after which the notebook
automatically enters suspend mode. You can set it to 5, 10, 15, 20, 30, 40, 60 min or
Disabled. When the time-out you specify elapses, the notebook becomes inactive; all
device activity is suspended and the processor is powered off. If the Suspend to
RAM feature has been selected, only memory is powered so that stored information
can be retrieved instantly when a resume event occurs. If the Suspend to Disk feature
has been selected, all information in memory is saved to a special partition on the
hard disk drive before the system powers off.
Since Windows 95 periodically accesses the hard disk and automatically
writes to the display, Auto Suspend sometimes does not work.
