When this machine hits about 75% battery charge, the machine will black screen, flashes a wild blue screen(almost looks like failed GPU screen on 2011 MBP), then will flash the folder with question mark. [br]
[br]
Unplugging the machine, then turning it on will allow boot into the user system. [br]
Then upon plugging the machine back in, operation of the machine is slower..? [br]
[br]
Seems to me like a potential failed logic board.. but I am not certain and would like some other thoughts. I have tried an SMC and PRAM reset… the wild behavior is still there.[br]
