So right after buying the Alienware M17X R4 with the HD 7970M I started getting these DRIVE_POWER_STATE_FAILURE blue screens of death whenever on battery. Simultaneously, I began losing sound. Sometimes after turning on the laptop, often after it resumes from sleep. Every day I have sound issues and every day I crash 1-3 times with that blue screen message (when on battery). I am forced to always stay plugged in, but I still have the sound issue.
I updated the drivers. All of them - display drivers, sound drivers, etc. I reinstalled the OS. I flashed the BIOS. I searched the forums. Right now, I am kinda out of options.
I used to think this was the AMD Enduro graphics switching driver problem, but I disabled graphics switching and began using the HD 7970M exclusively. I also looked up this issue and found out it was happening on the NVIDIA Optimus system as well.
Anyone have any ideas?
Thanks. :)
