[Bug 1463422] Re: Lenovo A740 doesn't poweroff on shutdown
On testing hibernation, the screen first blanked out for half a second,
then showed the desktop again, but unresponsive. I clicked the power
button, it turned off, then clicked the power button again, and it
resumed fine with my terminal open. So hibernation "works" except, like
with "systemctl poweroff" it doesn't actually power off.

Title:
Lenovo A740 doesn't poweroff on shutdown
Status in linux package in Ubuntu:
Confirmed
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.
