Hi, I'll be happy to help with this issue
Can you let me know how old the Macbook Pro is approximately?
thanks - I would try firstly to reset the PRAM on the Macbook Pro by doing these steps
There is also a potential nvidia fault which may be relevant dependent on when the laptop was manufactured
I think the restart button would be for different models so holding down the power button is the right thing to do
Does your macbook pro have a removable battery?
ok, can you try this?
ok, I will need to opt out unfortunately for another expert to take a look
you shoudl get a message from them when they are ready
This did not work. Logic board needed replacement. I bought a new Macbook.
