I bought this computer a while ago but it was my mom who was using it till now but I recently have a hold of it and I can't seem to find any kind of vaio drivers installed in it niether do I any feature to control the Backlight keyboard in this laptop the version of Sony I have is SVE1513CYNB.
One thing I would like to note is that I read somewhere that this laptop comes with a linux OS but when my mom first opened the PC it was loading Windows 8 (64 bit ) inside of it also there were no windows driver even then also my laptop now runs the latest version of Windows 10 (32 bit) in it!
