Apologies for the silly question - this is my first MacBook Pro
Tend to be OCD about things like this. Left my MacBook on the charger all day by accident. Just grabbed it and noticed the bottom of it was pretty warm - I am assuming this is normal?
If you have Power Nap enabled (most likely you do) then it will wake up periodically to check emails, weather etc. therefore it will remain warm as opposed to be sleeping all the time.
There's no reason to unless you're maybe worried about power consumption (it's off by default when on battery power)is it better to disable power nap?
