Power Button
Use the Power button in the following ways:
• Press the Power button to power on.
• Press the Power button to move from Standby mode and to proceed with normal
operations.
• Press and hold the Power button in place for 4 or more seconds to initiate power override
(powers off the notebook). Only use this option if you cannot power off your notebook
using the normal procedure.
Put the unit in Standby mode when you need to be away from your notebook for a short period
of time and want to return to where you left off. Standby mode shuts down all devices in the
notebook while retaining data and notebook status.
