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, the
computer stops some or all of these devices in order to conserve energy.
Saving power
Disable Fast startup
Your computer uses Fast startup to start quickly, but also uses a small amount
of power to check for signals to start. These checks will slowly drain your
computer’s battery.
If you prefer to reduce your computer’s power requirements and environmental
impact, turn off Fast startup:
Note: If Fast startup is off, your computer will take longer to start from
Sleep. If your computer features Acer Instant On it will also be turned off.
Your computer will also not start if it receives an instruction to start over a
network (Wake on LAN).
