OK. I use this 5430 with Fedora 37. The issue is that I put it to sleep, close the lid, put the laptop into my backpack and when I get home the laptop turns out to have been working for quite some time in the backpack.

And I know why it is so - I probably have some other stuff in the backpack which press on the chassis. And the chassis gives in and presses the keyboard buttons (I see several dozen of characters in the password entry dialog on the screensaver). So I know why the laptop wakes up. I just want to disable it.
