I’ve struggled with the intermittent ‘p’, ‘0’, ‘-’ key failure for the past few weeks. It’s worst when I open the laptop in the morning. After some use the keys function almost normally (but often produce a bounce/repeat). I opened a case with support and after sending photos and video they say “replace input cover and sorry, your laptop is out of warranty”.
I’m not thrilled in that the failure must be more localized than the whole input cover. I’ve done some troubleshooting and can’t convince myself that it’s the cable connecting to the mainboard. New mainboard is $109 + shipping + VAT/taxes. Not the end of the world but not great either.
