Actually both model 4925 and 4930 uses the same driver set but differ in certain aspect of other specification. My last post about this model was about 5-6 years ago, and the link already dead so I remake the list in case some of you still uses this old Notebook.

Acer One 14 released for Windows 8.1 64-bit and Windows 10 64-bit. That's why you will only find 2 OS supported drivers on Acer website. Since most people currently prefer Windows 7 over Windows 8 and 10, here I list out all drivers for Windows 7,8 and 10.
