in-one an update to your computer's buggy and outdated BIOS is available
(O14KT15AUS). If you update to this following
https://help.ubuntu.com/community/BIOSUpdate does it change anything?

If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report.

Once the BIOS is updated, and the information above is provided, then
please mark this report Status Confirmed.

Thank you for your understanding.

Title:
  Lenovo A740 doesn't poweroff on shutdown

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  If I do "systemctl poweroff" or use any GUI to try to shut down, it
  gets to the stage of

  [ OK ] Reached target Shutdown
  reboot: System halted

  but just sits there unresponsive, and does not actually power down.

  Similarly, if I try running "fwts -P", the hibernate test seems like
  it crashes the computer (screen is on but unresponsive), then if I
  click the power button twice, it resumes from hibernation just fine.

  If I try to reboot, it's almost the same, except the display shows
  weird psychedelic lines and colours, but everything is unresponsive
  and I have to click (and this time *hold* not just simple click) the
  power button.

  I can reboot fine from GRUB with ctrl+alt+delete. I've kept the
  Windows partition that came with the computer, that also powers down
  and reboots fine.

  If I click the power button while Ubuntu is started, it powers off
  immediately.

  I originally asked a question at
  https://askubuntu.com/questions/632591/system-does-not-power-off-on-
  poweroff-just-halts but I don't think it has an answer since this
  seems more likely to be a kernel bug.
