 Make sure you have the right power supply. The MacBook Pro uses 85W power adapters. The MacBook and MacBook Air use 60W power adapters. That's why my MacBook Pro didn't start. You can find the wattage by looking at the power adapter. I figured it out by multiplying the voltage with the current, like this: V = 16,5V A = 3,65 16,5 x 3,65 = 60,225W SoSo, it was a 60W adapter I was using, which was the wrong type of adapter. 16,5 x 3,65 = 60,225W SoSo, it was a 60W adapter I was using, which was the wrong type of adapter.

```Make sure you have the right power supply. MacBook Pro's uses 85W power adapters.

MacBook and MacBook Air uses 60W power adapters. That's why my MacBook Pro didn't start.

You can find it out by looking at the power adapter.

I figuered it out by multiply the voltage with the current, like this for example:

V = 16,5V

A = 3,65

16,5 x 3,65 = 60,225W so it's was a 60W adapter I was using.

Which was the wrong type of adapter.```
