It is a Medion laptop that I have not used for a long time. C.a half a year. The still image has been there for over 10 minutes.
See attachement
Then just wait.
I would still wait. 10 minutes is not long for a laptop that has not been used for half a year.
Battery out
If the loading symbol no longer turns then switch it off again
if not then you can try it out-on
maybe it just hung up
