I have done clean installation of Windows 8.1 on my HP Pavilion G4.
Then I realize that I cannot put my computer on sleep mode and cannot adjust screen brightness.
I understand that those problems caused by the graphic card driver.
My computer is running on AMD Radeon HD 6400 series.
Thus, I manually search on internet and found a latest graphic card update on microsoft site that is claimed compatible on windows 8.1 (link: http://msdn.microsoft.com/en-us/library/windows/apps/dn344644.aspx).
I've upgraded it into the latest one. I've check on Device Manager, the driver is running well.
But my problem did not solved!
Please give me the solution!
