[Lenovo IdeaCentre A740] Doesn't poweroff on shutdown
Status in linux package in Ubuntu:
With my Haswell based Lenovo IdeaCentre A740, 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.
