So my mother took her toshiba laptop and plugged in a different power supply than the one that belongs to it. There was a pop and smoke came out the back. I am pretty handy with computers and i think that a new motherboard would fix the problem. So I saw this listing on ebay http://cgi.ebay.com/toshiba-m45-s16...ptop?hash=item19b55ab8e6&_trksid=p3286.c0.m14 It's got a working mother board and would probably go for 60 bucks after shipping. Toshiba wanted 450 for parts and labor. What would anyone else in my position do? I think it's worth a shot.
Update to power supply. When the correct supply is plugged in smoke comes out of that back. Just wanted to add this to the above message
I checked the linked and it said the bidding has ended. Did you get it? As for your mother's laptop I would say there is a very strong proabability more than the motherboard is fried. Are you able to take the harddrive out and test it?
I would suspect the power board was the first thing that died, but probably other stuff as well...if you won that ebay auction, then it sounds like you should might have enough to get it working. I would transfer all the guts from the ebay unit to your mom's unit as a set; probably a bad idea to try the replacement mainboard with the old power board or vice-versa.
