I went to Acer.com and there are no Windows 7 specific drivers there. There are absolutely no 64-bit drivers for any Windows 64 bit OS.
Save your Windows 7 for use on another machine?
I installed Windows 7 on subject laptop and loaded all the drives. Everything works but the rocker switch just below the keyboard. I checked in my Device Mgr and nothing shows as negative. Which device would the rocker switch show up under, anyway?
