Tip to keep you from breaking your laptop AC plug

Quite simply, when you move your laptop around your house, unplug the charger.  It is very frequent that individuals will "bump" or "knock" the plug off the corner of a wall or the like.  Any kind of torque on that plug while it is still plugged into the laptop can easily result in a broken AC powr jack or Charger itself.  It's a simple thing to do to prevent heartaches in repair.    I've seen repeatedly people moving around with the plug hanging off the laptop.  This is why I am a big fan of Apple's Magsafe plugs.  They simply fall off, no way to break the darn thing.
