The location of laptop serial numbers varies among models and manufacturers, although many typically include the information on the bottom of the computer, sometimes beneath or near the battery. This information is presented as a series of numbers and letters next to a bar code.
The first place to check for a serial number on a laptop is the bottom of the machine on a printed label or sticker. If there is no label present, the user should power down the laptop and remove the battery, as this concealed compartment often contains the serial number to prevent accidental damage. Some computers also allow users to locate serial numbers through the operating system itself.
