Hello,
Am Paul, I just bought Hp Probook 4540s which comes with windows 8 pro, verything was working properly till i try to install windows 7 proffessionals, the pc was working properly but base system drivers was the problem. Now i have re-installed wondows 8 pro the problem is more worse. Only the base system drivers wasn't working but now even the fingure print is not working as well. Unfortunately I lost the Disc that came with the PC.
