    Lenovo Z570 vs Suspend

    Evening, all
    As the title suggests, I have a Lenovo Z570. Works great, except if I try to suspend the laptop. it seems I have a 50/50 chance of the screen coming back on.

    Looking for troubleshooting steps to hopefully achieve a proper suspend on this laptop.

(Perhaps its just an issue with the screen backlight not returning on resume - for which the kernel parameter acpi_backlight=vendor might help).

    Here are a couple of wiki articles on debugging suspend/resume:
