    Default Strange power problem with Acer laptop

    My wife's ACER V5-571 laptop exhibits a strange problem. If we run it and then power off it will power down and then immediately power on again, if we power it up and then do nothing but hibernate it will do exactly that and power down OK, if we run it for a while doing stuff like email and web browsing it will not power off at the end of a hibernate process. I have tried both hibernate and shutdown from a console and using the KDE menu items but the problems are the same which ever I use. The laptop is fully up to date with fixes on Leap 15.1. With regards to the hibernate it does have a large swap some 3 times bigger than the actual memory and swap is active. Also if I wait for a couple of minutes after it will not power down from a hibernate I can force a power off using the power button and it will resume OK!

    Now I have no idea where to start debugging this so I guess I'm asking for pointers for things to try?

    It might also be worth testing behaviour against the current stable kernel perhaps.

    The latest f/w available for this laptop is from 2014! So I think it is probably on but will check. I might try the kernel when I figure out how to, normally only update from the standard repositories. Strange thing is that on the older Leap this laptop worked just fine!

    Just checked and it does not have the latest f/w installed. This is an old laptop and ACER do not supply a standalone f/w update. It has to be using Windows and this is a Linux only laptop so I have to try to find a way of doing it but I dont want to install Windows on the laptop just to do this! Anyone any good ideas?

    Ok, so a likely kernel regression perhaps. Anyway, you add the stable kernel using

    Code:
    zypper in --from Kernel:stable kernel-default
    Be aware that if you have any proprietary kernel modules installed (eg graphics drivers), they'll need to be need to be rebuilt against this kernel.

    Thanks for that. Before I try anything I'll do a new back up as the laptop works apart from the power/hibernate issues and it's my wifes laptop so I cannot afford to mess up or I'll get loads of grief
