as wondering if anyone has hpdv4 2040 us & has ever replaced mother board. or has a spare to sell

I don't know of anyone having one to sell and I've never replaced a motherboard in an HP laptop before.

I have replaced motherboards in Dell and Toshiba laptops. They aren't easy to replace, you have to be very careful.

 

I'm sorry that I couldn't be of more help.

Hi, I cannot help regarding where to obtain a replacement motherboard as I am in the UK.

However I have to ask why you think you need to replace it and are you sure the original one is dud?

 

If you know for sure that it is a dud one I have found a useful tutorial for dismantling the HP DV4 series laptops here :-

I hope that is of help for you.
