Dell Latitude CPx Laptop will not POST

I have a Dell Latitude laptop that all of a sudden will not POST. It will "turn on" for a few seconds then turn right back off again. I have removed all of the perhiprials and I am running the computer off of the AC line.

Sometimes the computer will boot and get all the way to the desktop, but it will freeze in the first 10 minutes and then will not POST after that.

Please help me find a starting place to troubleshoot this thing!

since you already took it apart, is the CPU fan running?  Or is it a fan that does run all the time?
It defenetly sounds like a heat problem due to the fact that you can boot up sometimes and then freeze and then it won't come back on.

CPU fan runs. It doesnt really get hot at all. Thinking it may be a power/BIOS related problem.

I have had similar problems on a Compaq Presario notebook.  It would lockup in bios....lock up in windows....lock up during post test...didnt matter where or wehn....2 minutes...30 seconds.....5 minutes....and usually not more than 10 minutes.
My laptops problem was the motherboard.
Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

I would guess that you don't have any extra RAM laying around b/c it is notebook RAM.  I would if you could switch out the RAM and see if that does anything.  It could be several things:


I would not think that it is the p/s because it will sometimes boot.  If the p/s was bad it would not work at all or it would try to boot but fail all the time.

We had HUNDREDS of these Dell Latitude CP.. series.  CPx, CPi, CPi-A . . .  I 'm so glad to be rid of them.

We had to have replaced (under warranty) lots of these motherboards for these models, and it wouldn't suprise me if Wakeup is correct that it's the motherboard.
This question has been classified as abandoned.  I will make a recommendation to the moderators on its resolution in approximately one week.  I would appreciate any comments by the experts that would help me in making a recommendation.

Nope its still open. After $300 in motherboard replacment costs, $100 for a new power brick, and $50 for a new hard drive, it still will not boot.

From what I have read on the Dell forums this is a common problem with CPxJ and CPxH laptops. Any resolution would be appreciated.

My recommendation would be to PAQ & Refund points, and then for Codiak to post a new Q. with this information and even the URL asking again for resolution.

None of the new experts will have seen this, it just goes too far back, so PAQ'ing it (as opposed to deleting) ensures it remains for a URL to be given.  Refunding the points ensures points are available for the new Q...

to make this quicker for yourself, you could head to community support and ask them to do as AlbertaBeef(see i an get it right) reccommended
aask them to paq/refund and then to post new q with link to this one

No comment has been added lately, so it's time to clean up this TA.
I will leave a recommendation in the Cleanup topic area that this question is:


Please leave any comments here within the next four days.
