Lift up your computer and look for a tag.

The tag will probably be located on the side of the computer, or on the bottom of the unit for a laptop.

The service tag is generally a large black and white tag and it will say "Service Tag Number."

Do not confuse this tag with the Windows tag, which may be located in the same area on the computer.
