Chosen Solution
At around 70% my screen turns black and powers down, it automatically turns on after I plug in the charger. I made sure the film is off the baterry and everything is connected. Can anyone suggest what I can do?! Also sometimes my clock is reset to 12/31. Update: it even powers down when it is connected to the charger Update (11/17/2018) I have been trying to do this but it still fails. Some shutdowns resets the clock too. The battery charges way faster than normal so i dont know if its the battery or another solution to try. I try to do the SMC and PRAM but nothing resets for the PRAM even though i let go of the keys after the restart chimes. This didnt happen even when my battery said “service battery.”
