Magsafe adapter doesn't work. What should I check?
My Magsafe 1 AC adapter (from Macbook Air, 45W) doesn't work suddenly. No LED indication what so ever. No damaged visually find, even wire is fine.
I have a volt-meter, so I can check some resists or volt. Please let me know what should I check...
These are current status :
Pin 1+2 : Not shorted. 0.44V, 200k Ohm when not plugged in, 5M Ohm when plugged in.
Pin 4+5 : Not shorted. 0.44V, 130k Ohm when not plugged in, 2M Ohm when plugged in.
Pin 1+5 or 2+4 : Shorted, 0.0V, 0 Ohm
What I heard, it should about 6V when it's not connected to notebook. Mine does 0.4V only.
Help me please.
Is dit een goede vraag?
