Hello forum,

I'm still relatively new to the world of electrical repairs.

I have a Macbook here that I can't figure out

When the battery is gone, the USB input consumption goes up to 20 V and 0.06A. But it breaks down after about 2-3 seconds and you can also hear a small ticking on the logic board. But I can't pinpoint it exactly.

I removed the logic board and took a few measurements.

But I can't really figure it out.

At first I thought the infamous CD chip was defective - but then of course you read more on the internet...
