With the hotkeys, I ended up installing all the original drivers and utilities from the recovery disk rather than the updated drivers, running them all with compatibility mode and administrator rights.
I have managed to get brightness working and volume (after i set hkserv.exe amd hkwnd.exe to compatibility mode. Bass boost, zoom and eject finally work too.
This is all on a T-Series by the way, a T250
My question is has anyone managed to get the fn+f7 (external display function key) working? Also my dvd button, when I select the “Do not use as DVD button” option in Vaio Control Center, the button will ONLY set the display to Max Brightness, regardless of what secondary function is chosen.
Anyone have similar problems? Anyone got a fix?
pikey7: make sure you install your graphics driver. Search for your model’s graphics driver at http://esupport.sony.com and install it, then restart. This should work on a T / TX and maybe even a TR but I can’t guarantee it: ftp://download.sony.com/US/pc/INDVID-00770905-US.EXE
