I have a Macbook Pro 15 late 2011. The charger has started to act funky the last few days.
What happens is that I connect it. Light shows as green on the connector and then switches to orange if it needs to be charged.
Then after a few hours the computer just dies while the light on the charger is green. Clicking the battery check on the side shows full battery. But removing the charger and clicking again shows a totally empty battery.
At this point, reconnecting the charger doesn't show any light at all. I have to wait a few minutes connect/disconnect cables a couple of times. Then it starts charging. Then starting the computer again it keeps charging. Then suddenly at a random battery percentage number the light switches to green and just stops charging.
Disconnecting and reconnecting charger doesn't help and no light is shown again. Restarting here seems to help. But it keeps happening.
Resting SMC and/or PRAM doesn't help. The charger, the white square doesn't get hot.
