GPU manual swicth not working 6990m

hi guy my pc is stuck on the 6990M it wont allow me to switch to the intell
i uninstalled both drivers ccc and the intell one and installed them again and still not working
any ideas how to fix this?

 

Uninstall all drivers for both the 6990M and the Intel IGP through Control Panel>Uninstall a Program and Device Manager (including associated software) if needed. Then install the Dell July 6990M drivers. Those drivers include drivers for the Intel IGP. Do not install the separate Intel graphics driver shown on the Dell web site; those are for use with the Nvidia cards. After installation of the Dell drivers you should have no problem switching between the graphics options.

 

just tried what you said, the 6990m driver not prob uninstalling, the inthel went to control P. and done uninstall and reboot the pc but the sofware still remains there. on device manager booth were uninstalled , all it had was 2 standart vga drivers, then installed the 6990 like you said , it come up with an error
"aplication install : install package failure. "

still carried on and finished the instalating it , in the end said finished but with that error, 6990 is working but not switching still.

 

Which is the manual switch? FN F7? and how do you know which mode you are in?

 

ya Fn + F7 , if you right click on the desktop and right click it will come up with the option " configure Switchable Graphics" you click that and it will tell wich GPU u using mine is stuck on high performance

 

I guess you going to need to do the Driver Sweeper/CCleaner routine to clear out the embedded drivers and registry entries that appear to be scrambled. After uninstalling through Control Panel and DM (if needed) to the point that you have both cards at Windows VGA Adapters, then reboot into Safe Mode (tap F8 at the boot screen until the boot menu appears, select Safe Mode). Run Driver Sweeper ( http://phyxion.net/item/driver-sweeper.html). Select AMD Display only (scroll down and uncheck c:\ATI if present to protect any ATI reference drivers previously downloaded), clean and reboot. Then run CCleaner ( http://www.piriform.com/CCLEANER), click on Registry in the left column, Scan for Issues and then Fix Selected Issues (all). Repeat until no issues are found. Then reboot and install the Dell drivers. Drivers and Downloads. That ought to do it. Good luck.

 

Tried all that , still didnt work, there was a error when installing the CCC Software (6990m software) , so clean install as needed lol all done now all drivers installed and all working again. now its the long windows updates lol
thank you anyway , will give you +rep for the help

 

Also make sure you don't have any open programs when switching graphics. I remember someone posting that an open program can make it not work and after trying it I found it to be true. As long as I closed all my programs before switching, I had 100% success at switching graphics. Before that it was like 60%.
