The other day while I was clearing some space on my Sony Vaio PCG-71312L, I accidentally deleted the touchpad's driver. The mouse itself is fine, it's just that the scrolling is not working.
I looked around for the CD that came with the laptop, but couldn't find it. Also, I tried searching for the drivers, but with no success. Can someone point me in the right direction?
I am looking for a solution that doesn't involve installing softwares, the driver will suffice.
