I have a Dell Latitude D600, 1GB RAM, intel 1.6GHz processor, Windows XP Pro SP3 and it will not power on. Some of the lights come on and then nothing. I got got the BSOD and it booted a few more times after that and then nothing.

So where do I begin? I don't want to run out and buy a new motherboard when it could be another component. How will I know if it is the MB?

Any suggestions or if you know to any online resources I would greatly appreciate it. I looked on Dell's site and it is like a needle in a haystack.

Thanks!

Can you boot from a CD?

Some of the lights come on and then nothing. The laptop will not come on so I cannot run a CD. I did get it to boot a couple of times after BSOD and not it will not power on at all. I press the power button and few lights blink but no actual powering up.

When I was able to get it on I did the internal diagnostics on it and everything passed. Before ti craped out the next time I was able to get 1 pass in on a memtest. But now nothing. A few flashing lights thats it. The it shuts back off. How do I troubleshoot it to get the power back on so that I can fix whatever problem? Where do I start? I have not installed any new hardware and I promise there is no viruses or spyware.

Try running memtest86.

You download an ISO file, burn that to a CD (as an ISO), and then use that CD to try and boot your computer.

Sorry for the double post, but can you even boot the laptop to the BIOS?

Okay here is the situation. As of my post last I was UNABLE to turn on the laptop whatsoever. So no there was no way I could run any CD's or go into the BIOS. And I am thinking that this will occur again.

Last night after I got off of the computer I went and took out the memory, put it back in, used one stick at a time, etc and was actually able to get it to boot. First I went and set it to the last known good configuration and then I continued to boot the PC where it only continued to freeze. I then started a memtest and that froze as well.

Trying to isolate if it was the memory and which stick it was I was able to get a chance to boot using only one stick or the other and BOTH the sticks had a problem, the computer froze each time.

So now what? if I do lose power completely then how would I go about troubleshooting the issue? I ran the internal diags and everything passed. Do i not worry about total loss of power and just try and keep working on it when I do get it to come on and "hope" that it does not freeze?

Thanks!!

What was the error message noted on Memtest when the freeze occurred?

No errors on the memtest the computer was just frozen. I don't know where to begin to fix the problem. Just keep playing with it and "if" it boots up then try and run tests hoping it won't freeze? If it no longer boots up how do you troubleshoot a dead laptop. I don't want to run around buying parts, not knowing which ones are broken.

This doesn't sound like an operating system problem, but more like a hardware problem. Have you asked in the Internal Hardware forum?

No I didn't know what it really was at first but I think you may be correct! So I will have to take my question over there. Thanks!
