Probably not, given laptops tend to be highly customized hardware. Any options there may be would likely be so minor in difference it wouldn't really be worth the effort.
Also, be prepared for some sticker shock if you ever do find someone who understands what you're looking for. Out of warranty laptop repairs are almost always uneconomical given the cost of the unit. Expect to pay at least $400 for that board. Most people find it makes more sense to just buy a new unit.
I purchased an HP dv3-1000 laptop 18 months ago and now I need to replace the motherboard. My question is: Is there only one compatible motherboard - or are their a few motherboard options within the dv3 line I can buy? I'd like to have a motherboard that has an expansion port 3 for the HP Quickdoc.
I've tried HP customer support, but they always transfer me to someone with an accent who keeps trying to sell me a new laptop.
