Q: I need to replace a part in my HP or Compaq laptop, how do I find the correct replacement?
A: The first step you will need to take is to locate your HP spare part number. This number was created by HP and placed on all of their parts for the purpose of helping to find the correct and compatible replacement part. This number is sometimes difficult to locate, and some parts may have multiple part numbers on them, leading to extra confusion. Using this page, I will show you how to find and identify the correct HP part number for certain parts.
Here is an example of an HP spare parts sticker:
Q: I want to replace the motherboard in my laptop, where is this number located?
A: The HP spare parts sticker can be almost anywhere on the motherboard. Sometimes it may require you to remove the motherboard fully from the laptop to find your part number. One of the more common locations, which is much easier and less of a hassle to locate, is behind the RAM on your hp motherboard.
Here is an example of that placement:
Q: There are multiple HP part stickers on my motherboard. How do I know which one I need?
A: The easiest way to find out which number belongs to the motherboard is to visit HP Part Surfer and search for the part number in there. The extra HP part numbers are most often for the other detachable parts on the motherboard.
Here is an example where there are 2 extra part numbers on the motherboard. One is for the modem and the other is for the express card slot.
Here is another example of a part with multiple part numbers. In this case, there is also a model number for this DVD Drive. I always recommend that you replace HP parts using HP part numbers. Different laptop manufacturers may use the same model of DVD drive. If you replace using the model number, you may find that despite being the same part, it might have trouble fitting into your laptop, or come with a different faceplate. If HP’s part surfer can not find a part number, like 391649-6C0, you can Google the part number to find a replacement.
Q: I’m trying to replace an inverter in my laptop, however, there are no HP part numbers! What do I do?
A: You may find that some parts, like inverters, do not always have hp part numbers on them. In these cases, you must correctly identify the manufacturers part numbers on the part to find a compatible replacement. Here is an inverter that does not include an HP part number.
You can see the outlined part numbers on this inverter are YNV-W10 and 19.21072.101. Both of these numbers will find you a suitable replacement. You may find that upon looking for one to purchase, you see it listed for a different laptop model than your own. Do not worry, some parts are used in many different laptops and are compatible in many different models. As long as you match the part number you are replacing, the part you purchase will be compatible.
