HP Pavilion zv5330us had intermittent power connection now all the time- jack or heatsink?

[ohernova]

The zv5330us cannot get a good enough connection to remain on to complete full boot.  I need diagrams to locate the power jack and heat sink, CPU, or do I?  Replacing the battery didn't do a bit of good as the power isn't getting to the charging unit nor will it power on with DC Adaptor alone anymore.  This grew steadily worse.  Is there a source for tech specifications so I can replace these parts if I need to, and what about the CMOS battery?  Is it replaceable?

I do not find the service manual for this model notebook, however you can check if there is any LED blink codes being exhibited to understand the issue. There is a sample of the LED blink codes listed in the following document:

Connected the power source - the blue zigzag-LED power light is on in front - no error codes.  I will leave it in powered state to try and charge the battery a bit before proceeding in a few hours while I copy the drivers to a CD with the correspondent instructions in Word. This older laptop had a CD read-writer but not the newer DVD writer, I think.... So many devices, it is hard to keep them all straight.  Maybe another suggestion for a forum - how to keep all your devices straight with this software product >>>>>>> as yet unnamed <<<<<<<. Since cables and components bridge the gap between manufacturers, with small mods, it helps to get the consolidated listing of all components when you buy the things new.. HP had such a while ago and of course, I copied it onto said laptop, Pavilion zv5330us - which is, of course, the zv5000 family, unless HP broke ground with the 5300 devices - it would be lovely to see a matrix or historical exposition of how these evolved.  Sometime I think it would be better to have all the hard drives in a tower, accessible by remote, and for that I bought an HP USB drive, which had its hiccups.  Wonderful article "Cloud Services Showdown" in Maximum PC magazine, Vol 17 no 05, May 2012, comparing Google, Amazon,  Microsoft, and Apple's iCloud on page 38.  They didn't look at the HP or Linux or other commercially offered remote access to your data, nor other options in this article, just the Cloud-type services by the big 4 - but that is another Topic.

Aha! I set the laptop on the right angle, and as long as I don't move the DC Jack, it powered up!  Runs fine, too, so it must be the CD power jack is the problem, no?  Seems this Pavilion ZV5330us is a monster!  Keeps running, although I would like to redo the system, replace the drive.  What people need to understand is a computer is a compilation of the work of many factories, mostly in China and Asia, and there may be times when thousands of parts are faulty but installed.  The good thing is I have technicians in the family, and I know a Korean technician who runs a dry cleaning operation in Aberdeen, Maryland, who keeps his hands in with his electonic workbench, so my options are pretty good, even though the warranty is out.  I have a 16 year old laptop that still works, so I guess we are good at troubleshooting.  Unfortunately, the destops are another matter.  I just take out the data drives and use them as external sources to keep the information, unless the drive is shot.
