Ok, I've been looking around online for a solution to my Dell Latitude D610 failing to power on, but none have worked, and I think there are a couple details that are different from other people's problems. I'll be as detailed as possible here to give a good description of what's going on...When I press the power button, the power light comes on for a couple seconds and then goes out again, and there are no noises whatsoever coming from the computer. I've tried all the combinations of unplugging the power adapter, removing the battery, holding down various F keys, applying pressure to the buttons, etc etc...The thing that seems to be different with my problem is that immediately before this problem, my computer had inexplicably shut down. A few months ago I had a problem with the computer getting very hot and completely shutting itself down (I assume from overheating), but it stopped doing that for a while. Back when I had that problem, however, I was always able to restart the computer without any trouble. Now the same thing seems to have happened, except now it won't do anything at all. Since this all started with the computer shutting itself down, rather than simply refusing to start after sitting turned off, it makes me think it's not an issue of a loose connection or a faulty power supply...any ideas? could overheating have caused permanent damage?
