How to Identify Dell Motherboard Part Number

By Contributing Writer

Most computer manufacturers use a proprietary identification number scheme for their parts and accessories. Each one looks different, and some can be very confusing and hard to find. Dell has a fairly simple part numbering system, and usually makes them easy to spot. Their replacement parts and accessories all use the same system, and all have a small sticker with the part number and revision on it. You can use the Dell part number to find replacement parts on Dell's website, or on resale sites around the Internet.

Things You'll Need

  • Screwdriver
  • Flashlight

Find the Motherboard Part Number for a Dell Desktop Computer

Step 1

Turn off the computer and unhook the cables and connectors. Place the computer on a flat work surface and open the access side of the case.

Step 2

Use the flashlight to locate the white tag with the bar code. It will be somewhere near the memory slots on the motherboard.

Step 3

Record the alphanumeric value from the bar code sticker. The part number will be the second value. For example, the number on the sticker for a Dell Dimension 2400 is CN-OG1548-70821-36C-E01D. The part number is the second set of numbers, or OG1548. Use this number to find compatible replacement or upgrade parts.

Find the Motherboard Part Number for a Dell Laptop Computer

Step 2

Use the flashlight to help read the white tag with the bar code. It will be on, or somewhere near, the memory slots on the motherboard.

Step 3

The part number is the second set of numbers, or O5K117. Use this number to find compatible replacement or upgrade parts.

Tips & Warnings

  • Zeros and the letter O can look very similar. If you search for a number and receive nothing for results, try changing O's to zeros and search again.
  • Use a magnifying glass to read small or hard-to-see stickers.
  • Use caution when working near the motherboard. Avoid touching the board to prevent damage caused by static electricity.
