Hi guys, Recently my MB started to recharge intermittently. When i connect my laptop to the power supply the led randomly change from orange to green while the screen changes its brightness and, as a consequence of this, my battery gets recharged intermittently. I thought that it was due to the cable of the magsafe power supply but there aren’t any damages along it. However the problem is visible when the device is used, because when it’s off or in standby mode the led is orange until the battery is full charged, then it normally turns green. I tried to reset the SMC and i disconnected the battery but nothing changed Battery is at 90% of its health (according to battery health) and it has 835 cycles and it is 5.1 years old OSX El Capitan 10.11.4
Changed the magsafe recharger, problem fixed!
Inspect the MagSafe connectors contacts both on the cord and the system. You may want the clean them, use a cotton swab (Q-Tip) slightly dampened with some isopropyl alcohol (85% or better). See if that fixes things.
