Hi.

I am replying because i am also facing this issue.

The laptop is the same, 5740g.

The original OS is Windows7Home, and everything worked perfectly.

After few weeks Windows7Pro was installed, and again everything worked perfectly.

This week has been performed a fresh installation of an evaluation copy of Windows 8.1, (not an update).

The issue described here and relative workaround (fn+brightUp/Down and after fn+F6) is also happening here.

Maybe this issue should be reported to Microsoft, since is happening to the latest version of the operating system.

Or maybe to AMD, since i installed the latest graphical driver and the issue didn't disappear.

best regards

Drago
