HP-16C board is loosing - Can anyone help? :-)

[luckybuck]

Hope you are all doing well and are not affected by the cold from the north?

Over Christmas I got a 16C. Soooo lucky…. :-)

But the main board is loosing contact at the left side, please see below.

Further, there is a spring in the middle?

Do you have an idea on how to fix this the smooth way?

I mean, in a way, that the adhesive is not affecting the keys…

Just have seen hints to take apart the 4 screws in the backside, but does this bring me to the board at the front, too?

Thank you so much in advance, with warm regards from Germany.

Btw: the WP-34S gave me the possibilty to flash a HP-20b or 30b. So, if there is someone in the Aachen region, I would be glad to help out.
