Given the age of the machine and the symptoms you describe the first thing I'd suspect is a dead power supply unit.

since you have it apart, if you plug in the power adapter and then check voltage.  at this point your checking voltage with a "load" on it.  and will get an actual correct reading on your meter.

without a load your power supply can look good and still be bad.

 

if your voltage falls below 18volts then suspect the power supply is definitely the problem.  also it will verify that the connector on the computer side is good or bad.
