So, I have an MacBook Pro (mid 2010) running Big Sur with opencore patcher, and it just won’t turn on anymore after I opened the back side once.

I plugged and unplugged every cable I could see on the mainboard. And also changed that hard drive once.

When I plug in the charger, the light on the MagSafe connector turns on, but the MacBook still won’t turn on.

Any ideas? My google searches didn’t bring up anything helpful.

Thanks.

    Try turning off the power and all cords from the laptop and pressing the power button for 10-15 seconds. Then connect the power back and try turning it on. On the same model I had a problem with a dead battery and a dirty magicsafe contact

        Sadly it didn’t work, the light on the MagSafe connector is REALLY low. I can only see the light when I hold my hand beside it. But it still won’t turn on.
