Introducing Your NEC Versa 1-11
Power Button
The Power button is a “smart” switch, meaning that it recognizes when the system is in
Standby mode. If in Standby mode, you cannot power off until you slide the Power
button forward to resume operation. (The BIOS parameter “System Switch” must be set
to “Sleep.”)
Put the unit in Standby mode when you need to be away from your system for a short
period of time and want to return to where you left off. Standby mode shuts down all
devices in the system while retaining data and system status. Go to Start, Shut Down,
Standby to put your system into Standby mode.
Use the Power button in the following ways:
—Slide the Power button forward to power on.
—Slide the Power button forward to resume from Standby mode and proceed with
normal operation.
—Hold the Power button in place for four or more seconds to power off the system
(power override). Only use this option if you cannot power off your system
using Start, Shut Down.
