Hi DP-K,
The exact model of my laptop is HP ENVY 17-3290nr 3D Edition Notebook (3200 Series).
I upgraded Windows 8 Pro from Windows 7 Home Premium as instructed in HP page
Then I upgraded all drivers from the link you gave me, except the Bios because it was upgraded by HP Care Center in June 2013 (Version Insyde F.OB 2013-01-02) when it was replaced the keyboard.
There are problems that I can't overcome :
1- The backlit keyboard cannot be lit up, it only lit up once when windows started up after that no light (no sensor).
2- There is no 3D in the Cyberlink Power DVD for Windows 8, I can't watch any 3D bluray discs nor the 3D demo.
So I had to download again the Cyberlink Power DVD 10 drivers for Windows 7 but it can't work properly, I can only watch 3D demo video from the manufacturer. I can't watch any 3D bluray discs because after I insert the disc, the screen shows :
Information : The integrity of Cyberlink Power DVD is at risk. Check your anti virus software for malicious activities or try installing Cyberlink Power DVD.
I have done as above but nothing changed.
3- The Beats Audio can work but it often fluctuates and the sound seems not smooth as before, although I reloaded the IDT Audio driver for Windows 7.
Please show me how to recover these problems.
Best regards
