I fixed my laptop, because it was noisy and it was overheating, im not very good at keeping track of my screw, but with the magnetic project mat, i was able to keep track of everything. Another problem was the cpu, had a very old cpu and replaced it to a newer version which is a lot better and thirdly replaced the hdd to a ssd, with more space and it is faster.
The repair went well, cleaned the fan, replaced the cpu and changed the hdd to a sdd. So far everything works well, the repair was succesful.
Always keep track of where all your screws go, which ones you took out first and in what order. Also
