I have an Aspire 7730G too. If you look at the filename on the Acer website it is: "BIOS_Acer_3636_A_AS7730 TM7730.zip" so it looks like it takes the same BIOS as the TravelMate 7730. I haven't gone near the BIOS on mine though, well not yet anyway. I'm still on the stock BIOS which in my case is 3509.
