Power down the computer by hitting the button on the computer itself. You may have to hold the button in for several seconds. Once it's shutdown give it at least 30 seconds before hitting the on button again.
A blue screen at shutdown may occur occasionally but is usually not a critical issue. It would be advisable to check your local C: drive for any important work files, such as Word or Excel files, and be sure you have them backed up to your Y: drive.
Note: Important work files should not be stored on your local C: drive because they are not backed up. Your Y: drive is backed up on a nightly basis by Lan Services.
