AMD Mobility 4200/5650 Issue

[inouext]

Hi.

I have a HP DV6 3240 notebook with a dual graphic card 4200 / 5650.

Every time that i close and open the lid i loose the brightness control, Fn keys stop working, brightness sliders in windows disappears.
The only way to get back working is reboot the notebook or uninstall the monitor under device manager and scan for hardware changes.

With old HP specific video drivers i dont have this issue, but the performance in games are awful.
I am runing Windows 7 x64 with 13.1 catalyst from amd site, and i tried several others versions with same issue.
My power settings are set to do nothing.

Anyone have any idea ?
Thanks.

Cards ids
4200 – PCI\VEN_1002&DEV_9712&SUBSYS_1440103C&REV_00
5650 – PCI\VEN_1002&DEV_68C1&SUBSYS_1440103C&REV_00

Have you tried the 13.3 powerexpress driver? link - http://support.amd.com/us/kbarticles...etaDriver.aspx

If you do, and it still has the problem, report it using the feedback link on that page.
