Hi Aceguitarist.
All you can do is contact Vaio Support and list for them what is not working properly with the current driver.
There are new drivers every other week but most will not affect your Vaio. Sony will only update drivers if there is a known problem - they probably will not know unless you report the fault.
You can try Googling for "mobility modder" but I don't think your OS/ATI chip are supported.
