Your guide has helped me take apart and will help put it back together. Without any test equipment I would do exactly the same. Is there anything i could do to maybe fix this problem. I have uploaded every driver that I could find no thanks to HP and all the Win 7 updates from Microsoft. But not matter what I try, it wont flash because the stupid flash program thinks it is the wrong bios file for the wrong PC recognizes the wrong bios on the board and wants to flash the same crap only on it.

Just a reminder it is always better to remove the battery first before doing anything else. Upgrading the memory and you confirmed what I had to do. Try removing the screen bezel without separating the display panel. Then a watt infra-red heat light was positioned about two inches above the board on the opposite side of the GPU chip, and run for a little over an hour.

Remove four cpmpaq securing the top cover assembly. If the problem still there, most likely this is motherboard failure.

Susie, God bless you! I KNOW it still works though. I can get it to power up for a second or two but then I have to let it sit for awhile before I can get it too do it again.


Remove the hard drive. When it trys to load from the hard drive it makes a sharp hissing sound and switches of and on.

I bumped the top of my LCD display by accident a couble of weeks ago. When I plug it into the monitor my monitor on the notebook shows up a little but not much. I tested the power brick and even the battery with a multimeter and they seem to be working. Was the old hard drive still bootable? There is sound and i know my harddrive wasnt damaged since i removed and tried it.

I suspect the wireless switch is internally broken.

Unscrew the bad fan and replace it with a new one. When you assemble it back together do not forget to lock the processor socket and apply ff730us fresh thermal grease on the CPU. Being on disability its hard to just buy another.

Test the laptop with each memory module separately. Most likely they did but who knows.

It just stays where it is -just a black screen. The sound card is integrated into the motherboard.

Make sure the memory module is seated correctly. Hope this should work on Compaq too. I cut around the top of the GPU to give it some air. I have been trying to fix this problem for months and finally decided to go the external sound card route. Ok thanks When I bought Laptop it had Vista on it and now i think of it now i do hear from the hard drive,noises… also i know i need to put new thermal paste on the cpu compq.

I just discovered your link to a list of 58 mb repair deals. I also maxed out the ram to 2gig and gig hardrive.

You cannot replace the VGA card because the video chip is integrated into the motherboard. It opens and when I put a dvd in I hear it spin for a little while and then stop. I was woundering about this USB power board that is shown in your lesson on taking my lap top apart! The bigger sticker had these numbers.
