[Bug 1463422] Re: Lenovo A740 doesn't poweroff on shutdown
Kevin Brubeck Unhammer, as per http://support.lenovo.com/us/en/products
in-one an update to your computer's buggy and outdated BIOS is available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
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.

Lenovo A740 doesn't poweroff on shutdown
Status in linux package in Ubuntu:
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
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
I originally asked a question at
poweroff-just-halts but I don't think it has an answer since this
seems more likely to be a kernel bug.
