I have just finished another build of a Dell d630, and have run into a problem that I have never seen before. This machine boots and runs flawlessly on battery power, but goes to a black blank screen when I plug a power adapter into it (the computer dose not power off, the screen just goes black. I have tried three different power supplys, and two different batterys, and still no joy!
Are there any suggestions on what to try next?

:welcome: Streetman

It is a rather odd symptom I agree - possibly related to the DC jack port.

Have you tried connecting the notebook to an external display and if so what happened.

Have you tried the Dell built in self test (BIST) http://support.dell....354&lid=4837645

What happens if you remove the battery and connect the AC adapter only to power the notebook.

Is the DC jack port securely fixed to the MB.

On Ac adapter only-- starts to boot for about 2 or 3 seconds, then goes to black screen, computer seems to continue boot with black screen according to lights, but no video on screen or external monitor.
Dc jack is still firmly attached to motherboard.

Not having any way to test this board further, I think I'll just replace the board and file this one under "unsolved" until I get bored, and need another headache. Thanks

Yes notebooks are more difficult to diagnose and work with, is it possible to remove the screen without fully dismantling the chassis.

When I first got this board, it came to me stripped down to only the motherboard and bottom case. when I started testing to find the problem with this board, I even pulled it out of the bottom case and laid it on a couple of mouse pads with everything plugged into it. Still no joy.
I am supposed to have a replacement board coming.
