MacBook charging problem
I have a problem with charging on a MacBook5,1. The original MagSafe charger developed an intermittent DC wire and continued for two days before packing in and being replaced with a new one.
The replacement will charge the MacBook, but incredibly slowly. Both the bright orange and green LED lights do not show, instead there is a very faint green light. The Battery icon shows ‘Battery Is Not Charging’. The charger works perfectly on my MacBook2,1.
I have uploaded a screenshot of both MacBook's from the Power section of the System Report. From this it would appear that the info under AC Charger Information is blank for the MacBook5,1.
Does this indicate that the 1-Wire OverVoltage Protection is damaged? My understanding is that the 1-Wire system is shared with the DC+ wire from the MagSafe charger. Any advice or previous experience with a problem like this would be gratefully received.
