Programmable power button (Windows only)
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.
