Completing Important Tasks; Shutting Down The Computer - Lenovo ThinkCentre M90p Safety And Warranty Manual

Completing important tasks

After you have set up your computer, record your computer machine type, model,
and serial number. If you need service or technical support, you will probably
be asked for this information.

Shutting down the computer

When you turn off your computer, always follow the shutdown procedure for
your operating system. This prevents the loss of unsaved data or damage to
your software programs.
To shut down the Microsoft Windows 7 operating system, open the Start menu
from the Windows desktop and click Shut down.
