Drivers incomplete on Acer 4720z

go to the driver in the same section you just looked in, and un install the device and then go back in and re install it, and click on scan for changes on the same device that is a right click and it will automatically re install the drivers if they are there, it might take a bit.

if that won't do it go to the acer web site www.acer.com support downloads and download the appropriate driver and re install it and your back in business.

best regards

I think you need to download the chipset drivers package. that more than likely will take care of that issue.
