Has Gateway historically had problems with the power switch at the end of the monitor hinge?
MS2274 power switch problem
This was my daughter's computer at school. She had problems with it starting up intermittently at first. Instead of letting me know she was having problems, she kept hitting the power button until it started. Now it will not start up at all. The "Best Buy" tech agreed with me that it is likely the switch. It seems a waste to discard a computer because of a faulty switch, but "BB" quoted me a price to repair it that is almost as much as an equivalent computer. I will get another repair quote before I discard it.
