- 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. Make sure you have the right power supply. The MacBook Pro uses 85W power adapters. The MacBook and MacBook Air use 60W power adapters. I had a 60W adapter. 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: You can find the wattage listed on the power adapter. If the wattage marking has worn off, you can figure it out by multiplying the voltage by the amperage, like this: V = 16,5V V = 16.5V A = 3,65 A = 3.65 16,5 x 3,65 = 60,225W 16.5 x 3.65 = 60.225W So, it was a 60W adapter I was using, which was the wrong type of 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.```
