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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1594023 Title: Poweroff or reboot hangs. Laptop won't shutdown. 16.04 Status in linux package in Ubuntu: Confirmed Bug description: This is about a fresh Ubuntu 16.04 install on a new laptop (asus x540sa). After pressing the shutdown button in the start menu; the shutdown procedure starts and in the final splash screen the system just hangs. Tried a second time by pressing Esc once the splash screen showed up and I saw that it reaches the line "Reached target shutdown" and just stops there, no matter how long I leave it there the machine won't turn off. I also tried a Kubuntu 16.04 fresh install on the same machine and it hanged too at the final splash screen where the pulsating logo stopped. Then I tried with Esc only to see the exact same line in the end. The issue seems to affect lately quite many users as shown by the google results of the past month / week or so. I have also tried shutting down from the console with shutdown -and all the parameters after that suggested online- and sudo poweroff but unfortunately they didn't do the trick. The exact same situation occurred. Unmounting the swap as suggested online doesn't work. Also rebooting the system is not working either due to the same issue. So right now the only way for me to poweroff the machine is to press the power button on the keyboard continuously. Reproducible: Always Steps to Reproduce: 1.Install OS 2.Do something, anything or nothing 3.Try to shutdown or reboot Actual Results: The computer is not shutting down: "Reached target shutdown" and hangs there. Expected Results: Powering off the machine. For what it's worth, closing the lid won't suspend the system, but using the menu buttons for suspension will do it.
