Power Management
Power management saves electricity and extends battery life by controlling power
supply to built-in devices. You can set the power management properties in the
Setup Utility. The default properties are optimized for maximum battery life under
normal operating conditions.
Note that power management may not seem to function in the following
conditions:
• When you are using an application program that accesses the hard disk
periodically
• When the IR monitor is available (refer to Chapter 5)
• When Windows CD Auto Play is functioning
