DC IN Voltage Fails TechToolPro Diagnostic
I have a MacBook Air that sometimes doesn't startup at all.
So I ran the TechTool Pro 8 diagnostic on it and it has a sensor failure: DC In failed at 16.96v.
Does anyone know if there is a way I can fix this other than a new motherboard?
Ist dies eine gute Frage?

You may be using the wrong power supply. The Air uses a 45 watt power supply at 14.5 volts. All the other laptop products use a 16.5 volt supply. So if you hook up a MacBook Pro power supply you're going to see 16.5V to 17V on the DC-in rail (depending on the accuracy of the sensor).
