I recently installed a new linux distro on an ASUS laptop that has had its disks wiped clean beforehand. I'm using an EFI partion as my boot partition. Given I'm no expert I've been fiddling around a bit and the result is the halting sequence doesn't even start.
What I experience can be easily described in words:
key in any halting command (reboot/shutdown/...)
the screen goes blank save for a blinking cursor.
stays that way for all eternity
The only way to shutdown is by holding the power button.
This was also on the live cd while I was installing the OS, however the cd actually starts the halting sequence stopping all processes but hangs in the end.
When starting up and arriving at the grub menu, hitting the power button actually turns the pc off.
OS: Arch 230 (Jun 2016) PC: ASUS
I've redownload and reburned the iso and reformatted my partions many times, but this behaviour persists.
Edit: Tried with Ubuntu live cd and was able to reboot the ASUS.
Edit: I can shutdown my older Samsung laptop with the live arch cd. This suggests the issue is at vendor level firmware difference (maybe).
Edit: The following is a picture of where the live arch cd hangs on the ASUS.
