I once had to replace my laptop's motherboard because the gpu part of it fried due to a malfunction that cause alot of heat. I had to buy another motherboard at Asus, that was actually pretty cheap, 150 dollars, but I didnt want to pay another extra 100 dollars for, the technician to change the boards.
Well, I couldn't find the service guide, all the ones I found were diagrams, but not a guide on how to dismantle the laptoo, so I decided to figure it out myself. After 4 hours I managed to take the whole motherboard apart and extract all components, then another hour to install the new one. It was pretty challenging, but I managed to close the case with all parts in place and no extra screws lying around.
