CQ40 blackout, no power, won't turn on.

The problem is a CQ40  Celeron unit.  Problem initially thought was a faulty AC adapter.  It's not.  Unit won't turn on even w/ new adapter.

Checked the power component of the CQ40's mainboard.  Turns out, it's the zener diode, as shown on the picture with arrows and circles.  It is in the power section.  The zener diode is shorted.  That's the problem.


Behold, the zener diode.  We had to cannibalize from an old board.  It's hard to find this piece.  We got lucky to find one from an asshat's old motherboard, which is located in the video section of said asshat's board.
