I have had the same issue. I have gone through about 12 gateway/mpc laptops in the last two weeks... all smart or promethean users who have suddenly had a dead vga port. Of course, our warranty on these machines went away when MPC went belly up, so I'm at a loss. Paying $300 for a replacement board is really not an option.. We have had boards in the district for a while and haven't had this issue until the most recent round of installs. The installs were done by two different installers, so I don't think it's the install. I'm with most of the people here, I don't think it has anything to do with the board, but is some type of static issue. I just really don't know how to resolve the issue. Any suggestions?
