This made me smile because in my book this is at every effect impossible, especially if the goal is getting a functioning laptop at the end of the process. To be clear, it's impossible for me because I lack the knowledge, expertise and tooling to even think about doing it.
Nonsense, it just makes it more effort for you - nothing is impossible.
Also, the way you acquire the knowledge, expertise and tooling is by screwing around with stuff where you have no idea what you’re doing.
