Think he didn't mean that connector is shorted...Some mobos will switch on automatically when CMOS batt not present or totally drained...
That housing problem is pretty strange...Never seen that before myself, but it's possible that palmrest or bottom base is shorting mobo...
Couldn't be it some of the FPC connectors, ribbons or power board itself?

i can manage to power it up without the casing and with or without the cmos battery. it's pretty strange since there is no clue of what component is the problem. the laptop works fine without casing. but it automatically turn on when i plugged the charger

Try to change the rtc batt with a new one.
