I've also tried upgrading to kernel 4.6 as suggested in comment #58 and still have the same problem.

After upgrade, putting machine in suspend turns the monitor black and everything seem to be off, though the fan still spins, the power light is on and the battery is trained. Nothing seem to wake it up (Meaning different key combinations - trying to get a shell by Ctrl+Alt+F1, for example; pressing power, any other key). Unsure how to try to get it working since I have to kill the power by pressing down the power button, then restarting it (it then does a drive scan for errors).
