You can try cleaning around the button. Make sure it isn’t being triggered by some crusty sweat/grime. You could also change the behavior of your laptop, in the windows power settings you can change what that button does or how the laptop reacts when being closed. If both are set to do nothing, you would have to specifically turn off/sleep your computer but wouldn’t get any false sleep.

I don’t see a reason to federate with a corporation unless they were able to deliver something I’m not currently getting and their corporate support would greatly improve performance/sustainability for this instance. But based on previous experience, a company entering a space usually makes it worse.
