But before I write any answer did you try the usuals such as taking the battery out, no AC cord, press and hold the power button for 1 minute (yes it takes less time but I've lost count of seeing people hold it for 14 seconds when you need 15!)
Then slip in the AC and try again.
I have NOT researched your model to see if there is a reset button or CMOS BATTERY to replace. You do that.
PS.Answers Try the above and Yes to last 2 questions.
I bought my Gateway laptop in Nov 2007. After a problem-free year & 1/2, I returned from vacation recently (not having used it for 10 days) to find that the motherboard is dead. I have no Extended Warranty, & I bought it at (don't laugh) Circuit City. Geek Squad quoted me $400 ($200 ea/parts-labor) for repair. What should I do? It seems that a motherboard should last longer than 2 months, no? Am I screwed?
