Important parts on DV6000 and DV9000 series

Image
These are important parts if you are looking for shorts or opens on the DV series. This image shows the location of the FDS6679. A common cause of shorts in the DV series. When the power supply is plugged into the laptop and it shorts out/turns off it's usually caused by this MOSFET being shorted.  Plainly stated. You plug the adapter into the DC Jack and the Blue Ring fails to light up, and the Power Supply shuts off. Giving no power to the tip. To reset adapter, unplug from AC (mains) and wait 15-30 sec. Then plug in again. The adapter is not damaged, since this is how it is protected. These parts do not determine charge time or per centage. The FDS6679 only closes to complete Positive circuit.  The AO4407 only closes when the battery is plugged in. As a test- Check the voltage of the Drain side (pins 5-8) with AC adapter and no battery - you should see 0 volts.  When you contect the battery you should have 10-14v depending on DV6000 or DV9000 series. IF the AO44...

Gateway MA7/MA3/MA2 - Dead, Won't Charge

Image
Gateway MA7 - MX6958 * Centrino Duo Dead, Battery will not charge Works with good battery, Will not work with Adapter This unit arrived with a common problem that DC jacks presents. However when you continue to use with the defect, it eats the copper around the POS terminal of the jack. In this case the copper had been eaten away, as well as shorting between planes of the motherboards phenolic. So there is only one way to resolve it, by bypassing that section (if possible). The condition of this MA7 was too far gone to be able to bypass. One picture shows the scorching under the copper, the other shows the current path of the DC In. Will verify the model number when returning to shop

DV9000 Power Issue

Image
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?
