Find Model Number and Serial Number Of Your Computer Using DOS Commands

Computer manufacturers affix serial numbers to each unit they produce to identify any unit in question. The serial number helps identify what hardware is inside the computer and what kind of software is necessary to make that hardware function properly. The serial number also helps manufacturers keep track of which version of Windows, as well as which Windows build number, was preinstalled on the computer. And, most important, a serial number is vital when identifying a unit that may have been stolen. For these reasons, users should never remove the serial number from their unit.

   • On laptop or notebook computers, the serial number is always placed on the bottom of the unit and will always appear on some sort of sticker. Usually the serial number is identified as "Serial Number," "Serial #," "S/N," or "Service Tag" and is often within the vicinity of the manufacturer’s name or the unit’s model number. Depending on the manufacturer and year of the unit, a bar code sometimes appears near the serial number as well.
