How do you look up a model number for a laptop?

To find a model number for a laptop, the fastest and easiest way is to check the front page of the owner's manual. If the manual is unavailable, an alternative method is to look for the laptop's manufacturer's label, which you can usually find on the bottom of the laptop.

Besides consulting the owner's manual and manufacturer's label, a third way to find a laptop's model number is to turn it on, then navigate to Windows' "System Information," which displays detailed information about a computer's hardware and software. To access System Information, click on Windows' Start button, type "System Information" into the search box, then select "System Information" from the list.
