I have a VIAO VPCF111FX laptop. Just three combination of Fn work properly like Fn+F4 (volume up) works, and the others have no effect. What should I do? Is there any driver for that?

Beside that ASSIST, S1 and VAIO buttons do not send any signal too. (I tested it with AutoScriptWriter app)

Factory install of Windows dose not have thus issue, but I installed an orginal win7.

Is it running a factory install of Windows or did you remove some stuff/reformat it? – Akash May 29 '12 at 10:46
@Akash I installed an original copy of win7, not OEM version. – PHPst May 29 '12 at 10:53
Does it has three driver listed like this vaio event service, sony dll utils and Sony shared library. If yes then install them in the order I write them and please reboot every installation. – avirk Jun 2 '12 at 16:48
Also check in services.msc that Vaio event service startup is automatic if not change it to automatic. – avirk Jun 2 '12 at 16:54
@avirk From where can I download sony dll utils? – PHPst Jun 2 '12 at 16:59

Yes there are utilities and drivers for that. You sould have a few DVDs contaning drivers and utilities, if you don't, you can download them from the sony website (search for VIAO drivers) then enter model number. You should see all drivers and untilities suppored by sony for your laptop.

Short answer: You need to download and install sony shared library

For Win7-64 bit: http://esupport.sony.com/US/perl/swu-download.pl?mdl=VPCF111FX&upd_id=6832&os_group_id=6

Pressing alt+ctrl+fn keys together will solve the problem.

Will this also make the Assist, etc. buttons work? – techie007 Nov 18 '12 at 17:46
