Intermittent issue where it will not power up or powers down.
Visual inspection, stripped down and removal of all plug in parts. Need to perform some hardware reset actions that will not affect the data
No sign of physical damage or malfunction of parts. Got it to power up once, all plug in parts (HDD, Optical Drive and RAM) seem ok.
CMOS battery charge is with expected values.
Needs an internal clean, need to source an air compressor
