Recently I downloaded the latest driver from AMD official site and updated for my AMD Radeon Graphics HD 8750M (version 15.300.1025.1001 with crimson 15.12 windows 8.1 64bit). When I try to shutdown my laptop the windows shut down and turn the screen to black. However there are still lights on my laptop and cannot shut down it completely. I have to shutdown it manually by holding the power button. Beside, it has the same situation when I enter to sleep mode. I cannot wake my laptop from sleep mode.
The followings are spec for the laptop:
MODEL : ACER ASIPIRE E1-572G
Intel Core i7-4500U
AMD Radeon HD 8750M with 2GB Dedicated VRAM
8 GB DDR3 RAM
Windows 8.1 Single Language 64bit
