Linux Mint MATE 18, 64 bit, dual boot with Windows 10. Asus ZenBook UX305F; 8 GB; 256 GB SSD. In Windows, Fast Boot is off. Hibernate is disabled. In BIOS/UEFI, Secureboot is off; SATA is AHCI; Fast Boot is disabled; CSM disabled (but it makes no difference). BIOS has been updated to the latest.
I can successfully boot into either Windows or Mint.
When I shutdown in Mint (Menu|Quit|Shutdown), all seems correct. Screen goes blank, and all laptop indicator lights on the keys go off.
However, when I try to reboot with a normal short press of the power button, the power light comes on, but nothing else happens. No ASUS splash screen or anything.
If I then press and hold the power button for about 6 seconds, and then release, the power light goes off. I can then use a normal short push of the power button and the laptop will boot normally.
Doing a Restart does successfully reboot to Grub menu.
Another clue: the above failure happens only if the shutdown is done with the mains power connected. That is, if I shutdown while on battery, and then try rebooting (still on battery), it works fine. Also, if I shutdown on battery, then connect the power adapter, then attempt to reboot, it does.
Same symptoms if I boot from live CD. Fails with MATE 18, also fails with MATE 18.1 beta. However, live boot from 17.3 does not have the problem.
Sorry if there is a known answer, but could not find one.
