I am going to speak from the perspective as an HP Certified APS, and a carPC enthusiast.

First, often when there are issues with the ac input being "loose" mainly indicates the replacement of the motherboard, as it is the only way to fix the problem, ***UNLESS*** that particular model contains a daughter board that contains the AC input jack. Note that most HP laptops boards listed online are often times a DC DC voltage conversion board, but that will do you absolutely no good, as it has nothing to do with the jack. This is not what you need. It will most likely be a sub board, that, depending upon the model, also will contain the ethernet jack or USB ports, but not always, again, depending upon the model. I would not be able to tell for sure, because the only real way to get detailed info, would be if you told me what the Serial number and Product number of the laptop was. It is possible for me to get you the service manual for it, however, you may be surprised to know that most of the times, even we have to totally take the laptop apart in order to replace something as small as a daughter board. Granted, it is a pain in the *** but, when doing it as often as I do, you get resectively quick at it.

Now to address the BIOS system battery, or CMOS battery - these are NOT rechargable. They are a simple watch battery that sits in a specially designed location of the laptop, either straight on motherboard or in a sealed package with two power leads that plug into a spot on the motherboard. CMOS uses so little battery power merely to hold the systems date and time, as well as a few flashed BIOS settings, and the often times last for a few years before needing replacement.

Likewise, as aforementioned, I can see if I can get the HP service manual for you, since I have access to all that spiffy good stuff that the average joe does not, but no guarantees, since it is a home/home office class notebook. I typically work on business class notebooks and desktops, but I could definitely try to get it for you. The only things I will require are the serial number and product number. Feel free to let me know or ask me anything else, if you wish.

Brandon.
