DV9000 Power Issue
This HP DV9000 arrived with power problems. Difficult to diagnose simply by looking at the bottom side of the board (which faces tech when opened). When the power cable was disconnected from the board an obvious scorched connector was noticed. This 4 pin plug supplies power to 2 sections.
Not wanting to be too verbose, I will simply say that all 4 connections to the motherboard are needed and when one pin is scorched and oxidized, it cannot provide adequate current or voltage. So the plug end was replaced, and the interior of the jack was cleaned of carbon residue from the scorching.
The number of issues with this unit, makes for a days work. Power issues, broken LCD issues, SATA connector, USB port all on one machine. Everytime I fix one issue another pops up. And the customer wants it fast, but at a cheap price. When does it end?
