I also followed his instructions and it didn't work for me.
Tried it more than once with the stated drivers but nothing changed.
Good to hear that I'm not the only one, but very disappointing of course...
Have you spoken to Dell on this issue?
Haven't tried yet, only this support forum, but I'm almost certain now that it's useless...
In an other post with the same problem, a user named heropsycho however spoken with them, and got this as a solution:
"Finally received a response to my support ticket with Dell - they are now recommending a motherboard replacement (yes, seriously).
Also, they provided no information regarding an updated Radeon 8850/8870 driver."
Funny. This is the thread if you want to check it out: http://en.community.dell.com/support-forums/laptop/f/3519/t/19542391.aspx
Well... it did! So far, it works just fine. it even runs BF4! What used to happen too was the AMD driver stop working suddenly. It hasnt so far.
Update / WORKS NOW!:
What I did:
- uninstalled both video drivers
- installed both video drivers from Dell (versions A00)
- installed the generic AMD driver (version 13.9)
Now everything works; games, sleep, hibernate, etc. Seems like you just have to find the right combination until a decent driver comes out. Good luck!
use the Softpedia Secure Download link as the External leads to AMD's site where this driver is no longer available (afaik).
Thanks a lot for sharing this info Gaborsz, tthat did the job! Now everything works as it should. Finally!
I wouldn't have found that driver by myself (probably), as indeed it's not available from AMD. (Isn't it good practice to offer previous driver versions?)
Anyone tried the new AMD catalyst mobility 14.1?
I tried Catalyst 14.1 and doesn't work.
In fact, the solution here really works but it is a terrible old driver. The most recent drivers don't install correctly.
I don't know who I should blame, Intel, AMD or Dell.
