I have a Mid 2014 MacBook Pro with Retina Display. As of a week ago, occasionally when I plugged in the MagSafe Adapter, the LED doesn't light up. The problem is fixed by unplugging the power adapter from the MacBook and plugging it back in.
Should I worry with this? Is it an indicator for something wrong?
Last time I remember with my previous MBP, I had the same issue and it was getting worse, and then the logic board died.
