Just picked up an old Omnibook 600CT which is a 75mhz 486 for free and it won't boot. I can plug it in and I know it has power because a green light turns on. I'm thinking maybe the battery isn't charged enough because it's been sitting for a while. I don't have much expirence with laptops so does anyone else have an idea why it might not be turning on. I press the on/off button but it dosen't do a thing, no movement, beeps, or any output to the screen. Thanks.
