Removing Thinkpad Edge E420S screen cover

[timveld]

Dear all,
Somehow some dirt got stuck between my Thinkpad Edge E420S screen and the "glass" cover. How can I remove this cover? It is locked in place by 2 screws which came out fine but I can't get the cover off, I could get parts of the cover luse using a small screw driver but it seems there's something else locking the cover in place. Hope someone can tell me how I can get this cover off safely and clean it.

Have the same problem with my new E420S - any ideas?
