I have a Compaq Presario v6000 that fails to work anymore, the casing and hard drive are shot. I want to know if any parts from it are "standard" enough to work in a budget system.
Also, I realize I can find this out by opening it up... ~_~
If I get a non working laptop, I typically (but not limited to) do the following -
Take out, Hard drive, memory, cpu and the screen.
If the hard drive is bad, it is good to keep as spares as you may one day need to use the board on a different hard drive (if you have no plans on ever doing this, don't bother).
Screen - if in good condition / able to clean, then I sell them as second hand on repairs (can easily get £50 each), and if in bad condition, I take out the CCFL tube.
CPU - Well, usually eBay is the best bet if I can't re use
Memory - For the stash! - and again, offer cheaper for second hand upgrades.
Extras (but not always recommended)
Keyboards - Take a look, People actually sell individual keys on eBay!
Anything else - eBay again! take a look, people sell anything that can be unscrewed and removed, from chassis to other parts.
I used to also unsolder the DC jack and a few other components that can get burnt easily, but it is more trouble than it's worth and I would rather send off to a third party so I get a warranty and don't have to worry about warranty on returns.
The same place, I give the used chassis to and they give me a discount when I need other repairs done - if there is any place local to you, you may want to try and get a similar deal.
