Al - the case

S - probably a component of the Al alloy, it helps with machinability

Li - the battery, possibly also the case alloy

B, P - semiconductor doping

Cu - Almost certainly used somewhere

Pb, Sn - solder

Anything else?

Not much Pb in modern solders (in fact in the EU you can't add lead to any solder, I think you can have trace amounts if they are "naturally" there).

Modern solder is pretty crappy compared to the stuff I used to work with in the 80's and 90's, it's much trickier to work with, whiskers are more of a problem and I've found (the few times I've used it) that it seems to require more heat.
