How to open HP Laptop 17-cn0154ng?

Hello,

I have a problem opening my laptop 17-cn0154ng.

I removed all 10 screws I could find, including the 4 hidden under the rubber strips.

Otherwise, I can't find any screws on the side, and there are no stickers on it to indicate where some might be hidden.

But it doesn't even move apart by a millimeter.

The problem is a touchpad that is stuck on one side because the cat walked over it.

It can't be removed from the outside.

Thank you very much in advance.

Best regards
