HI GUYS
after updating to win 8.1 with the 7520se with the 7730m drivers i to encountered the endless problems with getting everything to work but finally managed to sort it and post below the steps i took to help others .
this post is a lot more recent than the others and includes the latest updated drivers from amd
first off goto device manager and uninstall both amd driver and intel driver and delete the software box
2. reboot
3. connect to windows update and install the latest intel driver
4. reboot
5 . install driver fusion and run and delete any amd software left .
6 goto leshcat labs . net and download the 14.4whql unifl v2.2
7 reboot pc
8. run leshcat and at the bottom it will now see what intel version you are running and the word deploy will highlight click that and wait .
9. you will then be taken to a screen with a amd folder ,a intel folder and under those you will see a installer batch file right click and run as admin .
10 a cmd prompt box will appear and it will say click s to start
11 this will then install the intel driver and say its older do you want to overwrite click yes ( dont update to a newer one or ccc will not work.
12 when this has installed it will ask you to reboot do this and wait when your pc restarts a amd screen will pop up and you will be prompted to install the amd
13 follow the instructions basically install and wait when prompted reboot it will take a few mins and you will have a black screen with a few cmd prompt boxes flashing but wait and all will be good .
i can now set all programs and right click works to configure both drivers are fully working and newer than the dells.
ive not tested yet for a score as i have been trying to sort this for like 8 hours lol and now its bed time ill test tomorrow and report back
hope this helps at least one person for what is a great laptop with very very poor customer support and product support from dell
