Flexing stuff, be they connectors or even the board, can cause broken contacts to pull apart. May be a dry solder joint, perhaps. I'd recommend not pressing down on the casing.

I don't just go pressing the caseing, but even the typing of the keys makes it do same thing...

Unless you can locate where the flexing is causing an issue (use whilst out of the case and being prodded maybe) it's going to be diffifcult to spot where the problem is. But if you give it a try and then apply a hot soldering iron where it seems likely to need one, you may fix the issue. If not comfortable with that then probably let a PC workshop take a look at it ?
