My Asus K53SD is affected aswell, but only if I install elementary OS in UEFI mode. If I enable Legacy BIOS and then install elementary OS, sleep/suspend works fine, instead I lost restart, no matter the kernel - currently on 4.2.0-999-generc. The interesting fact is that restart works in UEFI mode, but suspend dows not.
