My first time disassembling a laptop

We disassembled a Fujitsu laptop. We all took turns unscrewing the back of it. We also took a part the keyboard and the screen. It took around 2 hours. It would have been faster, but we forgot to separate specific screws. We did separate the big from the small, but their were around 4 different screws. The hardest part of this process is putting the laptop back again. It was fun, but I will take more precautions next time.
