I have a MacBook Pro 2012 13" (Non Retina) model,
The MacBook has no backlight keyboard and the MacBook does not sleep when you shut the lid.
I feel the issues are related and it could be damage to a ribbon cable, but I'm not sure what one.
I have tried SMC and PRAM Resets and it has had a fresh High Sierra install so it is not software related
Thank you for any help
