Hi, my laptop restart automatic (sometimes several times/day) without warning or notice that someting is changed and that a restart is needed. it restarts while i am working on it.

any idea what can be the rout cause for this?

thanks, Guido

The most common cause would be Windows Update, as that can force restarts -- but those generally happen only once a week, when they push out their weekly updates.  I would not expect this repeatedly throughout the day.
