One of the worst things that can happen to a person who loves dismantling and putting things back is that once you put something back together, it does not work. And this is what exactly happened to me last week.
I had opened my laptop thinking that I would clean the CPU fan. I opened the laptop and managed to reach till the point of removing the keyboard. But reaching the fan seemed like a huge task. So in favour of time I put the laptop back together thinking I will do mu exercise on a weekend. This time when I put the laptop together it worked in an instant.
Couple of days later when I again opened the laptop I went till the point of removing the screen assembly. This time when I put the laptop back together, it did not boot :(.
I tried multiple things, from replacing the battery to reassembling it, but nothing worked.
I gave up hope and now the laptop is lying useless. I bought a hard disc case and put the laptop hard disc into that.
