I've been having trouble with my computer lately. It started maybe a month ago. I transport my computer on the weekends, so one round trip. I brought it back home once, and after hooking everything back up, I pressed the power button and it wouldn't turn on. All that happened was the power button, which is normally blue, was amber this time, and the green light on the back of the computer, presumably on the power supply, would turn off. When I hold the power button to turn this amber power light off, it turns the green light on the back of the computer back on. This green light is always on in normal cicumstances, on or off. It's probably a bad idea to do, but the amber light stays on even when the power cord is unplugged.

I never quite figured out how I was getting it to boot up exactly, but after I got it to boot, everything would function normally. In fact, after transporting it and getting it to boot that first time after being hooked up again, every time from then on until I transported it again it would boot just fine with no problem whatsoever. To prevent it from having a problem booting, I would make sure I didn't leave it unplugged for long, and it would boot up fine as long as I left it plugged in for a little while first.

However, last night when I brought it back and plugged it in, even after being plugged in all night it refuses to boot. So I'm figuring there's something wrong with either the power supply or the motherboard from what I can gather, probably, but I'm not sure which, if it is one of those. I heard it was a good idea to turn the power supply off when transporting it, but I found out mine does not have a switch, just thought I would note that.

Today I tried unplugging everything but the monitor and the keyboard and see if that would work. I also tried checking the cords to make sure they were hooked into the computer well, and they seemed to be. I have not unplugged them however for fear of breaking the motherboard or something. I did note that the motherboard's amber light is on whether or not the amber power light is on or off, whether that changes or not when it's booted normally I don't know. I also confirmed that the cords plugged into the power button weren't loose, I checked them as well as I could.

Hopefully I've accounted for all relevant information (I probably have a lot of irrelevant information too, but just to be thorough):

I copied the specs from the Dell site, since I can't access my computer to find out. I had to guess at a couple things that I can't remember, but probably aren't relevant anyway. I did copy down what I thought might be important from the power supply and the motherboard. I'm using someone else's computer at the moment, so I'll check this thread when I can. If I could get some help that would be great.

Edit: I also posted elsewhere, Vostro 400 Fails to Boot, Solid Amber Power Light - Desktop General Hardware Forum - Desktop - Dell Community, I hope that's okay.
