I only noticed the messages that appeared on the terminal

As a general rule, my laptop is always on the charger because the battery
doesn't hold up very well

I went back to '39' to fix the problem but went back and forth between '39'
and '40' to double check

I only get the messages to the terminal on '40'

Hope this helps

Regards,
Steve
