Laptop in a car crash
I was once asked to repair a laptop that had been in a car crash. The car had gone over a telagraph pole in the road at night (it had fallen off a lorry apparently), the pole had ripped out the petrol tank, which exploded.
The driver survived as did his laptop which just had a few burn marks on the casing but when he tried to boot it he got the error "non systems disk or disk error" so he brough it to me to see if I could do any thing with it.
I ejected a floppy disk from the drive and it booted fine.
This was in about 1994.
