Hi,
I have been experiencing some issues when SSDT-9 is present. Perhaps, this SSDT is made to disable the AMD GPU which is not present on my machine, as it only has HD4600. Is it possible that the attached SSDT-9.aml from this threads E6440_A14_HS.zip file can be amended to remove the AMD GPU stuff.
Regards,
Mohamed
