Power management

This computer has a built-in power management unit that monitors system activity. System activity refers to any activity involving one or more of the following devices: keyboard, mouse, floppy drive, hard disk, peripherals connected to the serial and parallel ports, and video memory. If no activity is detected for a period of time (called an inactivity time-out), the computer stops some or all of these devices in order to conserve energy.

Your computer supports the following power management standards for reducing power consumption on your computer:

•Advanced Power and Configuration Interface (ACPI) for Windows 98 and future, supported operating systems

ACPI is a more recent power management specification jointly developed by Intel, Microsoft, and Toshiba. ACPI enables Windows 98 to control the amount of power given to each device attached to the computer. With ACPI, Windows 98 can turn off peripheral devices when they are not in use, thereby saving power.

•Advanced Power Management (APM) for Windows 95 and Windows NT 4.0

APM is a power-management approach defined jointly by Microsoft and Intel. A great number of software packages support APM to take advantage of its power-saving features and allow greater system availability without degrading performance.

If your computer is set for APM, you can set timeout values for your computer’s devices before power-saving methods are applied to these devices. If your computer is set for ACPI, Windows handles all power-saving chores for your computer.

For general information about the Windows power management system on your computer, refer to the Windows user’s manual.

Note: Power management (APM or ACPI) greately prolongs your battery life.
