Hp Dv1000 motherboard problem

Hello,

I have an Hp Pavillion DV1000 I am working on for a customer. The laptop was completely dead. I did some research and troubleshooting and come to the conclusion that the DC power jack was bad.  I could not get any voltage from the backside of the jack ordered a new jack and soldered the jack in place.Still no power.
I ended up suspecting mobo was bad.  My customer said he did not want to spend over $100 on a motherboard. I found one for his system on E-Bay from a company that had 98% feedback.  I did realize that the new motherboard was going to need some components from the old board soldered onto the new board. One was the new board did not have any power switch,infared diode, or speaker out port.  I sucessfully soldered all these components into the new board.  Went to test the board and all I get with new board is a quick flash of blue lights along the top where there are media controls and quick play acess for the optical drive. There could be a possibility that the board is bad or my soldering is not complete.  I have  a 30 days to return the board.  I e-mailed the company about the problem of either getting an exchange.  The warranty might be void since I had to solder these components into it. I would appreciate any and all help with this problem.

It is nearly impossible to diagnose a desktop motherboard, let alone a more complex laptop motherboard without sophisticated factory equipment - these are multilayer circuits that can have a problem in any of a thousand places.  You should have tested the motherboard before any modifications to it, to at least ensure that it worked as advertised.  Sorry for the bad news, but you may have to eat the cost on this one.

The board had no power button.  I had to solder the button to power the laptop.

The company I bought the mobo from sent me another board. All is well!
