Battery is bad, or the Power MOSFET's in the DC - DC circuit on the motherboard; are bad...........

Using the HP Pavilion dv6000, and HP Pavilion 9000 series of Notebook PC's; as an example,

Alpha & Omega Semiconductor LTD - AO4407 - Power MOSFET,

The AO4407 is Obsolete.

Where are these power MOSFETS located on the motherboard, for the HP G42 series of Notebook PC's?
In the DC to DC circuit on the motherboard.

Where is that?
Where the DC Power Harness plugs into the motherboard,

http://www.ebay.com/itm/HP-CQ42-DC-POWER-JACK-CABLE-DD0AX6PB00-/150980034385?pt=UK_Computing_LaptopAccessories_PowerSupplies&hash=item23271c7f51

[ The jack on the laptop that you plug the AC adapter into, {Charger}, is the DC Power Jack.

When the DC Power Jack is connected to wires, or a cable; it is then known as a DC Power Harness.
Some refer to it as the DC Power Cable ]

Let's look at an example of a motherboard, as used in the HP G42 series of Notebook PC's,
http://www.ebay.com/itm/HP-COMPAQ-G42-G62-CQ42-CQ56-CQ62-CQ64-Intel-478-LAPTOP-MOTHERBOARD-605140-001-/350675071935?pt=Motherboards&hash=item51a5dcf3bf
The large main photo that automatically comes up, is a TOP view of the motherboard. To the far Right is where the DC Power Harness plugs in.

You can set your mouse cursor in the middle of the photo, and this activates the Zoom In feature.

How do I know? I'm looking at the Service Manual right now,

HP pavilion laptop ZV6203CL will not charge the battery anymore, even a new battery, and will not use the battery power, will only power up when plugged AC. Is this a problem in the board or the AC DC...


This must be due to AC DC Power Jack. Test your Laptop with a new one. It can also be the Power Configurations in he Windows Control Panel. Do check those settings also.

I am not exactly sure what is the problem. Are you certain it is a power problem with the mother board? It could also be damaged or non functional.
Here's a troubleshooting guide from HP that might help you.

My HP dv7 laptop wont turn on I purchased a new battery and a new cord it worked for an hour then shut off again!!!!!!!!!!


Your DC connector is loose from the system board:


Problem symptoms:

  1. Laptop randomly shuts down without any warning.
  2. Power LED and battery charge LED start flickering when you wiggle the power cord or the AC adapter tip on the back or your laptop.
  3. The battery will not get charged.
  4. When you plug AC adapter, the laptop appears to be dead and there is no LED activity at all (DC-IN jack on the system board is broken).

If your laptop is out of warranty, then you can fix the problem by resoldering DC-IN jack on the system board. If it's still under warranty, it would be fixed at no charge to you.

HP Pavilion dv6000 plugged in not charging, I have a new battery.....PLZ Help.


Its the DC charging jack that you plug the charger into on one of the sides of the laptop. Do a google search, go and search for "HP dv6000 DC jack problem charging" (leave out the quotes) and you will see this is a common issue with the dv6000 and laptops in general. Many will just replace the whole laptop motherboard as the DC jack is attached to the board. If you know what you're doing, you change out the jack, quick repair job and keep your own board, but fixed. I would fix it if it were mine. You may be able to find someone local online but if you need someone to do the repair, I'm in the repair directory, as are many others qualified.


Note: It may come to a point, or the situation may just fit better to replace the entire board instead of the port alone. This is usually when the jack is not seated and easily replaceable, or if you are under warranty, HP will replace the whole board.

Your DC Power Jack is bad, or the area of the motherboard where the DC power jack attaches to, is bad.

The DC Power Jack, is the small port where your AC adapter,(Charger), plugs into.
This is an example of an average DC Power Jack, for an HP Pavilion laptop, not installed in a laptop yet,
http://www.megaemarket.com/dc-power-jack-hp-pavilion-ze4200-zt117420011721182125.html
If you click on the photo it will enlarge.

The DC Power Jack in the photo is upside down, in relation to how it sits on your laptop's motherboard.
Those flat metal pins shown on top, go down through the motherboard, and are soldered on the other side.

1.Sometimes when the 'charger' plug is in the jack, and is bumped, it can crack the solder joints for the DC Power Jack's flat pins. This makes an intermittent contact. Eventually there is no contact at all.

2.Sometimes it's a bad design of the DC jack, and just from ordinary usage of the user plugging in the charger, and removing it, this can crack the solder joints.

3.Sometimes the small area of the motherboard where the DC power jack is mounted, can crack away from the main body of the motherboard.
To explain:
Crude example;
Envision a laptop's motherboard as having a 1 foot square shape. (It isn't. It's irregular shaped) Now on one side attach a 2 inch square. This 2 inch square, represents the area that the DC power jack is attached to. A 'Peninsula', if you will. There are circuit traces that go along a motherboard. Think of them as Very, flat, thin, strips of copper wire. These 'wires' become stretched, and break as the 'peninsula' cracks away from the main body of the motherboard.

Solution?
Have the DC Power Jack replaced, or the motherboard.
DC Power Jack cost? About $6 to $8 dollars.
Labor? $100 to $150.
The tech has to completely disassemble the laptop, to just the bare motherboard in hand. Then unsolder the DC power jack, resolder a new one in, and reassemble the laptop.
Motherboard cost? About $150 on up. Depends on where you obtain it. (Ebay?)
Labor? $100 to $200.
