How do I remove you cover of my laptop?

So now I have deleted all the screws of my laptop but I can't get the entire cover with the keyboard away. What do I have to solve?

You should not even open the cover if you are not a specialist.

So if you do not know what you are doing wrong, you should either let it, or expect that you will break the laptop with it…

And the guarantee is lost

But you have to know that, therefore

Laptops are screwed and welded in very different ways.
So every brand and every model you have to disassemble differently.

If you search online for exploded drawings or manuals, you may find the info you need.

Ansonnsten I can only give you the tips that often screws are hidden under stickers or Gimmi feet

And sometimes (but not normally with Acer) under the keyboard so you have to take the keyboard out first.
