No power even when plugged in, drawing low power

Hi @zoranic

It could be a faulty charging port. Did you try both Thunderbolt ports to check if they are both faulty or if one is OK? Go to p.3 (p9 of 64 pdf) to view the ports)

If only one is faulty then use a strong light and a magnifying glass to visually inspect the port to see if there's any lint etc, trapped in the port enclosure which may be preventing a good electrical connection and also if the pins are OK or if some are bent etc.

If both ports don't work, you will need the hardware maintenance manual and the schematics to find out what's wrong. (supplier example only as I couldn't find a free download online and this was the cheapest one).
