I have the Aspire 792G and a couple of keys on the board went out. Because I don't want to deal with the keyboard being plastic soldered to the palmrest I'm trying to purchase the keyboard + palmrest. It is proving especially difficult to find exactly the VN7-792G. I'm wondering what other models are perhaps compatible, e.g. I'm able to find 791G and I'm able to find 793G. From the pictures everything looks the same and at least on the 791G it indicates the 17 inch monitor. Is there anyway to know if these are going to be compatible or if other models are compatible witht he 792G other than buying and trying? Thank you for your help!
