Apple MagSafe2 Power Adapter: Dim Orange charging light

Sun, 05 Oct 2025 19:10:47 -0700

Original Apple 85w charger, clean like new, no damage or bends on the cable, the Pins on the connector and the charging port are spotless clean but the orange light when charging is quite dim (Green light is bright OK), It is charging the MacBook as per normal and is not getting hot. I tested the MacBook with another charger and it is much brighter (normal). The battery is getting old and will be replaced when the replace now message comes (910 CC 74%). What is possibly causing this? Dying charger?

Apple MagSafe2 Power Adapter: 2.43V load voltage with magsafe 2

Tue, 08 Aug 2023 09:43:21 -0700

Hi,
My magsafe2 has a 3v no-load voltage and 2.43v when I connect a 40kohm resistor.

It's tested both at the cable end and inside the box where the cable is soldered.
Any common problems that can cause it? Schematics that can assist to trace the problem?

Thanks!

Hello, I have a MagSafe 2 (45W) charger that is not working, apparently there was a short circuit (the wires broke), I fixed the wires, and measuring with a tester the output is 0.6V, when it should be 3V according to the documentation. Can you give me some idea of what the problem might be?

Thank you.
