Wallstreet II power question


I have a 233 MHz Wallstreet II that needed to be repaired as the top of the case was damaged... It also needs a new CD ROM drive... It currently had a blank hard drive and, of course, needs an OS. It does not seem to charge the battery correctly now and after flashing the icon that it is looking for an OS for a while, it shuts down. Question... is th the PMU board under the top of the case or the charge board? Any thoughts... I truly won't be able to test it 'till I get a CD ROM drive and can attempt to install an OS.
