If you've ever had to repair an old computer without the motherboard manual, you know just how tricky that can be. Luckily, these days the basic documentation for many motherboards can be found online if you know how to look for them.

  1. This can usually be found near one of the four edges of the board on the top side (the side with all the connections, chips, etc. showing).

  3. For best results, form your search by typing the manufacturer name in quotation marks, and then type the word AND, and then type the model number exactly as you saw it on the motherboard. For example:

    "Fred's Motherboard Factory" AND FCMB920103

  4. Watch in particular for results in PDF format, as most manufacturers that do list their schematics online will do so in PDF (Adobe Acrobat) format.
  5. If you do not find the documentation you need within those search results, search just for the manufacturer, and find their telephone number.
  6. In most cases, they will be happy to direct you to the appropriate section of their website.
