Well tried to tap as long as possible, the bug did not move even a 0,1mm
So this is a hardware forum so take it apart!
On youtube there was this video how to remove the bezel by just using your fingers and it worked beautifully.
At the end corener where the buttons are use extreme care not to damage the vulnerable flatcable and after 4 tres petite (very small) screws were removed the bezel was off and also the plastick back
So power on determine where the bug was and put compressed air on the side....... nothing.
Step 2 removed the iron bezel of the display
but it came off easy
Hold it in place powered it up again compressed air and I could see the top displaypanel wave as in the wind , oh oh.
Still bug did not move
Now last attempt I lifted a small side of the panel with a screwdriver and again applied pressurized air..... bug did not move.
I guess the bugjuice dried up and glued it to the display, I am not an expert and don't dare to lift up the entire top panel, too scared something will damage permanently.
So I guess I will have to live with this pet
unless someone else has a clever idea.
