Hi! What you and Mayer describe is resetting the PRAM. To reset the PMU (which would definitely be a good step), with the power off, hold down the power button for 10 seconds until you hopefully hear a tone and see the sleep light flash.
 
I would shake the machine lightly to determine if you hear any loose screws. It's very common for a loose screw bouncing around to short out the board. Boards can be killed in this way, however more often than not they do power up again later. Obviously though in such cases it's important to get the screws out.
 
Similarly, if the memory cover is out, the metal Airport antenna plug very commonly will short out the computer by coming in contact with the RAM or various places on the board. So if it is flopping loose, I'd definitely hold it aside.
 
I'd also remove the battery while testing, both to kill power to the machine and let it recover from being shorted out (if in fact that's what's happened), and also to rule it out as part of the problem.
 
Also, as far as the weak battery issues, go to versiontracker.com and download Coconut Battery, a free utility. It will tell you the true capacity of the battery and let you get to the bottom of that situation. If may have 30% left of what is only 1/20th of it's original chargecapacity, in which case that 30% could be expended in a minute or two.
