English

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, hard disk, peripherals connected to the

computer, and video memory. If no activity is detected for a period of time

(called an inactivity timeout), the computer stops some or all of these devices in

order to conserve energy.

This computer employs a power management scheme that supports the

advanced configuration and power interface (ACPI), which allows for maximum

power conservation and maximum performance at the same time. Windows

handles all power-saving chores for your computer.
