    Uhhuh. NMI received for unknown reason 30 on CPU 0.
    Do you have a strange power saving mode enabled?
    Dazed and confused, but trying to continue
    Not the first time, but this time I have log data.
    The day before I put the laptop into hibernation.

    Then today morning I boot the laptop it starts shows the lock screen but seconds of the clock freezed and no response at all.
    As the laptop is new for me I am not absolutely sure but a ligth at caps flashed fast... I think it is the storage load light.
    Some seconds later the laptop rebooted.

    So what was / is the problem? What can I do? Someone any idea?

    looks like the error is not related to the problem as I already had the problem without the error.
    Still no idea but did not appear for a while also no idea if it is just luck or is fixed or maybe because try to avoid to use hibernation.
