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.
