I have a gateway model #MA7. It is a few years old now but when I try to power up sometimes it works and other times nothing. I have noticed that the red battery light when you push the power button flashes when the battery is in. If you take out the batterty the light doesn't flash. And at this time when the light flshes red nothing happens. when it powers on the lights are blue and it works. i have taken out the ram and no beep codes or anything. It is just random when it powers up. but when it is working it runs just fine.
