This issue still persists.Mine is an Hp laptop with an Intel Bay Trail processor, Intel HD graphics(Not Nvidia), 8GB RAM with Dual boot Windows and Ubuntu 16.04.2. Bios version F.46 and kernel version 4.15.0-55-generic
Whenever I try to SHUTDOWN/RESTART/SLEEP the Screen goes off(Black) but the Hard Disk keeps spinning with power button light ON. sometimes while doing shutdown the screen hangs on Ubuntu logo with dots. when esc is pressed it's seen that after [OK] Reached Target Shutdown nothing happens cursor blinking or Freeze. I tried to Re-install ubuntu with 16.04.6 while installing it displayed error related to APCI. somehow it got installed and when I checked dmesg it showed this error message "ACPI Error: [\_PR_.CPU0._PPC] Namespace lookup failure, AE_NOT_FOUND (20170831/psargs-364)" and this "ACPI Error: Method parse/execution failed \_SB.PCI0.LPCB.EC0.IPCL, AE_NOT_FOUND (20170831/psparse-550)" I tried almost everything I found on internet acpi=force, acpi=off and other stuff. It's discouraging from 2016 to 2019 there is still no permanent fix for this issue. some people on internet tried some or other fix for some it worked for some it didn't. Did anyone one of you found the fix for this ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1594023 Title: Poweroff or reboot hangs.
