After 3 years of treating my travel notebook, a PowerBook G4, with extreme care, it has been dented on the left front corner. I was at a small networking conference (only 50 people) where we all know each other (2nd time we all met) and I left my PowerBook unattended for probably 30 minutes, but within eyesight. I didn't find out until I got back to my hotel room, but somehow someone managed to put a nice dent in it right at the left front corner which slightly pushed a small section of the left side, just back from that corner, outwards. I'm thinking I could use a 13" rubber clamp and tighten the clamp enough to where it would pull the pushed out section back in, but I'm wondering how brittle the metal is that the PowerBook is made out of. Does anyone know if it will resist the bend back or will crack? I'm curious if anyone has any ideas. I imagine it's made out of aluminum and I'm pretty sure aluminum can resist remolding like that, unless it was treated differently than most aluminum. Anyone know? Picture attached.
