dell d600 won't power up

[needums]

Have been trying to turn on lights come on then cap locks blinks then everything shuts down nothing ever shows on screen. What can I do?

Double check that the memory is still seated properly. If that looks good, your system board is shot.

We see a lot of this same failure on the D600's here at work. Most of the time it's the systems board.

I'm sorry but thats a VERY poor way to troubleshoot...
Check the memory and then assume the Motherboard is shot?

Open the side of the case...
blow out all the dust if any
reseat all cards, memory, cables, etc
check for burn marks, or rounded/leaking caps
set a small house/box fan to blow air into the open side
Unplug the power supply chord, and press the power button
replug-in the power chord and try restarting.

If it still doesnt start....
try unplugging all but the bare essentials to boot the PC
unplug all USB devices, the optical drives, the hard drives, and all but one memory stick, (leave the one closest to the CPU)
try taking out any PCI cards except the video card
Try restarting now...

if it still wont boot, swap memory sticks if there was more than one
Are there any beeps?
At this point it could be many things
Power supply, motherboard, CPU

I'm sorry that I don't meet your standards, JP.

First of all, the D600 is a Dell Latitude NOTEBOOK, so there isn't a lot of troubleshooting to do.

Second of all, we have over 2500 D600's on the floor at work & we see this exact issue several times per week now that this model is approaching 4 years old.

Dell Tech Support will tell you to do the following...

1. Re-seat the memory.
2. Replace the memory with known good memory.
3. Replace the system board.

Wow... my bad there...
I misread what the model was and assumed it was a desktop...
Sorry about that..
