I recommend you back those precious pictures up to a DVD, USB drive or somesuch, the temperatures and stress, plus water damage it has endured will have been immense. You should always back up and have copies of precious data, not having your only copy on one computer, or the cloud.

I wouldn't have recommended plugging in a seriously water and fire/heat damaged laptop. I actually find it hard to believe this story is true, somehow, as common sense should tell you NO.
