Solid
My T60 was in a house fire. The bag was melted around it and then it was fire-hosed. Then the dripping mess was tossed out of the house onto a heap of rubbish on my lawn and frozen overnight. I cut it out of the bag, popped the DVD drive, the battery and the HD, wiped it down and set it aside to dry for several days. Then I reassembled it and it booted right up. That was two years ago, and it's still running fine. I bought it new because I wanted a tank. I got one! That's one tough laptop.
