[QUOTE="denmmx, post: 218073, member: 21493"] @alphastar thanks a lot for your answer, but my problem still not resolved... I'm downloaded SP59147, SP59149 from HP support page, installed AMD driver first, then Intel HD driver. Intel driver is [I]signed Intel-only[/I], so AMD card and switchable graphics not working - shown on screenshot: [ATTACH]19691.vB[/ATTACH] I observed that Intel Media Components, included in [B]SP59147 [/B]doesn't contains ID of my Intel card - [B]PCI\VEN_8086&DEV_0106&SUBSYS_1670103C[/B] in the [I]\swsetup\SP59147\Packages\Drivers\Display\W86A_INF\C8146815.inf[/I]. My ID not listed in this file. In a similar driver for Windows 7 ([URL="ftp://ftp.hp.com/pub/softpaq/sp55001-55500/sp55025.html"]SP55025[/URL]) this ID is present, so it's installing and working perfect for Win7. I also tried to edit this inf-file by inserting string with my Intel-card ID, but then Intel-driver installs only with Digital Signature Enforcement option disabled / "test"- mode (because modified inf-driver does not pass the digital signature check). Bundle of Intel HD (SP59149) + latest AMD Catalys Beta driver 13.3 also not working, again due to the lack of digital signature of AMD in Intel HD driver. [/QUOTE]
