Condensed version: My laptop (HP Pavilion dv4000, bought August '05) hasn't worked in a couple years, but I played around with it and sort of figured out what was wrong with it. I noticed that if I firmly press on the area around the touchpad it will run perfectly like the day I bought it. However, if I'm not pressing down on that area, it will stop doing anything: loading, animations, recognizing any kind of input. The weird thing is that it doesn't freeze, it just stops. If I press back down on the bottom area, it will start running again like nothing happened. This applies no matter what it is doing, anything from booting up to sleeping when I close it.
I opened it up and from what I could tell in the manual, it seems like the problem is coming from the area where my PCI comms module and battery pack are (around page 70 in the
manual). I'm not sure if it's one or the other, and I don't know too much about laptop guts so hopefully someone can recognize what might be going on.
Here's a couple pics I snapped:
The piece towards the bottom is the PCI chip, which was removed so I could see what was underneath.
This is the battery; does it matter that it's not really inside that circle? Reading up I figured out the battery is held down with double-sided tape, but there's no real connection between the actual blue section and the board.

My initial solution was to tear up part of a notecard and make a maybe 1/4" stack of paper to sit between the PCI card and the cover, which held it down for me. But that didn't last too long, so I'm wondering if maybe there's some kind of glue/adhesive I can get if it's the battery, or if maybe it's the port the PCI card plugs into that's somehow loose. Anyway, any help would be great, and I'll provide any other info you guys need.

Edit: I guess it could also be the battery portion, but either piece should be something you can order from HP. Either that or remove the blue plastic, check the connection inside and re-wrap it with electrical tape.
