Hi All, A few months ago my MBP Pro would randomly switch off whilst I was using the laptop. I then took it to an authorised apple retailer who advised me that it was a battery fault and that it would need replacing to which I replaced the battery ( a friend of mine did this for me to avoid the costs.) However, a few days after I am having the same problems. The MBP would randomly shut off whilst I’m browsing or try to open applications like photoshop. Sometimes it powers back on and most the times it would not respond to SMC or PRAM. A few times when the mac does switch back on it decides to switch back on when I’m trying to log in ( the progress bar freezes and the computer shuts down)The battery condition is also good. I have checked first aid to run tests to see what the issue is but the same problem occurs. The only time I can use the macbook is if Im playing a video or if i don’t do anything at all. Could this be a logic board or hard drive issue? Your answers would be really appreciated as I have no clue as to what is going on! Thanks,
I think you’ll need to run the built in diagnostics function in the system to get an idea whats happening. After restarting the system and you here the Bong press and hold the D key once its run though the diagnostics save the output and paste it here for us to see.
My MB Pro Retina did the same and I resolved (finally - after Apple failed and some 8 months of only using in Clamshell mode) in the end by cleaning the hall effect/reed switch or whatever Lid Proximity switch with contact cleaner. I posted a “question” that explains on this solution yesterday. I tried all the SMC and PRAM resets but problem was the pc thought the lid was closed
