I'm working on a notebook for a friend and looks like the motherboard is shot. The notebook is a presario 2720US and he's found a motherboard on ebay that is listed as a 2700. Are they compatible? Will the 2700 go into the 2720US?
My guess would be yes if they have a numbering scheme like HP. Basically the 2700 would be a series? I am guessing though. I would compare pictures of the mobo's. Does the seller have any high res pics of the mobo? Without having the mobo that is the only way to tell.
What you need is the part number on the motherboard. It appears that HP used the same part for both notebooks in the list. Either way, HP's website is a good place to start when it comes to part compatibility.
