Dell XPS 15 9550 Motherboard Replacement

Inleiding

Motherboards are usually the last thing to check if something isn't working, unless you have a specific diagnosis. For this laptop, there are chipsets attached to the motherboard, so if you have a damaged CPU or GPU, you will likely have to replace the whole unit.

Thankfully, this device's construction is not super complicated and you should be able to easily complete this repair. Take extra care to keep each step's screws separated, as there are many different components to remove before you can access the motherboard.
