Laptop which immediately reboots on shutdown
« on: September 03, 2020, 09:43:23 AM »

I have a laptop running linux which will reboot itself 9 times out of 10 within a few seconds of shutting down and powering off (power light does go off). Just occasionally it does not do this and usually only if I power off without running any programs! I have managed to update the BIOS using a little known key combination on powering up as normally you need windows to do it. Still not fixed it. If I allow the reboot as far as GRUB (linux boot loader for non linux types) and hit the power key it will go off and stay off! I've  tried loads of things but so far not been able to fix the issue. The problem is that the laptop belongs to my wife so she hits the shutdown button and closes the lid and walks away, of course it reboots and eventually runs the battery down!

I know it's a long shot but if anyone here has any bright ideas please let me know as its driving me nuts!

I had a similar problem with a Gigabyte Brix, it turns out that you need to disable?/enable "ERP Lowest Power State Mode".
Stupid thing would reboot in seconds! making it almost impossible to get into the bios sequence :-X
The machine had Lubuntu installed on it.

Nice idea but my Laptop BIOS has no such setting and neither does Linux.

Nothing like that in the BIOS, it's an ACER V5-571G.

The other fix I came across was to make the Bios Windows 7 Uefi
Some Bio's you can select Windows 7 or Win 8.1 boot

I just been round to my neighbours to check her Bios settings ... ErP disabled and Win 8.1 Uefi boot

This is all very well but my BIOS is nothing like that it is 'Phoenix SecureCore Tiano Setup' at the top of the screen. This is a UEFI laptop which does not run any Windows OS, it runs Linux as I pointed out earlier. None of those settings exist on any BIOS screen.

Ok.... so a quick scoot/google around found your post last year on updating the Bios... I can see no entry for you to change much in the Bios! only later version for selecting Uefi or Legacy!
That only leaves changing the Kernel startup by appending acpi=off :-\

Sorry Stuart cross posting

The reference to Win 7 / 8.1 switch in the Bios, changes how linux handles the acpi tables... :-[

Yes I was trying to avoid acpi=off as this machine is ACPI V3 compliant according to the service manual. I just tried acpi=off and got immediate kernel panic  :o Yes I have seen about that and there are acpi options one can add to do that where there is no option in the BIOS, and I've done that but does not fix the issue.

Which linux distro is installed?

I found this thread https://bbs.archlinux.org/viewtopic.php?id=192685

So "Laptop mode tools" seems :fingers: :fingers: :fingers: to have solved it for user :fingers:

I have openSUSE Leap 15.2 on that laptop. I'll look into that, thanks.

I think I've fixed it I installed laptop_mode_tools package and rebooted to start it on boot and since doing that it has shutdown and stayed off every time both on battery and with PSU plugged in. Hopefully it will stay that way now  ;)
