6 mo. old 13" rMBP, SSD. Won't wake/start. Battery was almost depleted when my daughter plugged it in. Charger light is orange. It hasn't been charging long enough to turn green, so I'm not sure if it is charging. I've now noticed an extremely faint ticking sound, about 1/second, but only when the charger is plugged in. Any ideas?
