RE: inspiron 15r se (7520) radeon fix here.

This looks like this just might do the job, But allot of this for me is very confusing? are you trying to say" delete all Drivers-AMD and INTEL----use a driver sweep clean up all traces....

Than let windows update both drivers....After both drivers have been downloaded---Wait till amd is finished...Restart and than disable ULPS?

Can you use the program that disabled ULPS, or should I do this manually?"""

I just Purchased a Dell 15R SE...with a HD 7730....and for the life of me can not figure out the switchable graphics...My kid plays alot of online games, and this laptop will not play them with the Card...Even when I set the Chrome Program to High Performance>>>still wont use the card....I am about half tempted to go back to Windows 7....This Windows 8.1 seems to have a ton of issues.....

let me know if this is the fix and I will try it right away...
