I have the basic white mac laptop and I've had it for almost a year. When I came home yesterday to use my laptop, some of my keys were not working well. Some of the keys like the 'N' the Delete key, the 'F', the Spacebar weren't working at all. When I clicked them, nothing happened. So I rebooted my computer and again to no avail. I left my laptop off for the rest of the night and when I woke up this morning, my computer wouldn't even start up. When I clicked the power button, the screen stayed black and it kept making these three beeping noises. The three beeping noises kept repeating itself, and the little light on the bottom right of the keyboard kept flashing in sync with the beeps. It did not continue to the start up screen or the start up mac jingle. I left it beeping for a good 5 minutes and fearful that there may be an explosion, I shut off the computer. What's wrong? It hasn't even been a year yet!
