Programmable Power Button; Changing The Power Button Configuration (Windows Only) - HP Z220 SFF Maintenance And Service Manual

Programmable power button

With ACPI (Advanced Configuration and Power Interface) enabled, you can customize the behavior of
the power button so that rather than powering down, the workstation enters sleep mode (low power
state), or hibernate mode (very low power state). This lets you go to standby without closing
applications, and then return to the same operational state without any data loss.

Changing the power button configuration (Windows only)

To change the power button configuration:
1. Select Start, and then select Control Panel > System and Security > Power Options.
2. In Power Options Properties, select Choose What the Power Button Does.
3. Select the desired options.
If you choose sleep or hibernate, you can press the power button to go to standby, then press it again
to enter full power state. To completely power down the workstation, select Start > Shut Down.
NOTE:
If the computer is unresponsive, press and hold the power button for four seconds to
completely turn off power to the computer.
