i'm trying to run windows 7 64bit on my sony vaio vgn-fz21m and having a huge issue. Well all drivers seems to work fine, but laptop keyboard stoped working after instaliation. I tried to connect a USB keyboard adn it was just fine, working perfectly, but my laptop keyboard doesn't respond.
The previous version was Win 7 32 bit and it worked, but 32 bit supports only 3 gb of ram. I want to use all my 4 gb ram and well i can't.
Could anyone help me, please. I searched answers in several forums but no luck.
I found the solution. I was instaling my sony over MDT, ant there was injected a synapsis pointing driver and that driver killed the keyboard. after unistalling the driver everything just worked just fine. now running win 7 64 bit.
