Hey guys are you able to help me out? I have got this on kernel parameters pcie_aspm=force acpi_osi='!Windows 2012' acpi=force acpi_enforce_resources=lax acpi_backlight=vendor acpi_sleep=s3_bios However when I try to suspend, the laptop just wont suspend or it suspends(randomly). But when I try to wake up I have got the same issue as before: blank screen. I'd have to reboot blindly again to use the system
