I don't know for certain what the solution is, but I have installed Windows 7 on my 700-15ISK, and all of the brightness keys and sound keys work correctly.  I think  (not sure) that this capability is provided by the Lenovo "Energy Manager" tool.  There are numerous versions available for download from this site, but I would suggest trying the following version (which is the one that works for me):
