Here's a question - will leaving the 140W brick connected to power full-time harmful to the brick? The MagSafe3 end is not connected to MBP unless charging is needed. Currently my setup is such that the brick is hidden in a cubby compartment to reduce clutter however I am interested to know from some of you, esp the more seasoned or tech smart folks on the long terms effects (and any possible harm?) of leaving it connected as such. Thanks in advance.
