Latitude CPx

I have this old Dell Latitude CPX. It will not show any video or boot. I have taken the keyboard out and found that some card that is attached to the motherboard by screws has a burned chip. The card has a plastic covering that had a melted spot. Now I have removed that card trying to get some info off of it. I can't seem to figure out what it does. After some research, it seems that it may be some sort of voltage regulator card. Can anyone shine some light on this?

It seems that my other thread got deleted because I included my ST number. It was deleted before I got to read a post that someone posted.  I could really use your help again. Thanks...

Can you post a picture of what you are talking about?  That might help to identify the component in question.

I believe this is what you are looking for. It is a Power Board. I bought a CPx board
with the same burnout problem on that board. D P/N is 0502U

Hi, need help. I have Dell Latitude Cpx model No. PRX, "Latitude C Family".  I push the power button, the hard drive light comes on for a second, the screens back lighting comes on, and then everything just turns off. The battery charging light stays on though. Don't know what to do, do I need to take the computer apart? Does this sound similar to your power board problem.  Anything will be appreciatied. Thankyou.

Try using your RAM modules one at a time in both slots singly and see if it will boot with any configuration. The CPxH/J, the CPtV/S and Inspiron 3700/3800 series all use the same mainboards and all are prone to develop Bad RAM slots. If no joy there, try reseating the CPU/Integral circuit board next. If that is unproductive, you can then obtain a Power Board and try it; the first two checks will cost nothing to try first before you spend money on a power board.

I have the same problem, but it seemed to work for a while if I would open and close the top, no it will not boot at all. Some had said it is the magnetic switch, if this is true how would I fix or dissable the switch?
