HP ProBook 4540s, i5 3230M 2.6Ghz, 8 GB RAM, 750 GB HDD, Intel HD 4000 & AMD Radeon HD 7650M, Windows 8 x64.
I have the same problem, but after I have done all that Blurey said, the result was not what I expected.(I have updated to the latest driver versions from Intel and ATI).
PerformanceTest gives me a score of 533, which is slightly greater than the Intel HD 4000 score.
All the settings are made to "Maximize Performance".
In addition to the problems I already had, the Windows Experience Index fails with an error when I try to Re-run the assessment.
And all the default apps from Start panel are showing a "black screen" when I launch them.
I think I must go back to HP drivers for both graphic cards.
Onestly, all I want is to control which graphic card is used by my laptop.
Is there a way for disabling Dynamic Switchable Graphics and enable Fixed Switchable Graphics?
Or any other solution that gives the user the decision over his computer? :robotmad:
Thanks!
