Turning off the computer

To properly turn off the computer, shut down the operating system software.

IMPORTANT:

Holding down the power button to shut off the computer can cause loss of user data and

might damage the storage device. If the system becomes unstable and no other alternative is available, give

the system sufficient time to wake completely after you restart the computer. This might take several

minutes, especially on larger-capacity or solid-state devices.

Select the Start button, select the Power button, and then select Shut down.
