Hi all, I have recently experienced a problem with my MacBook Pro in which the computer suddenly shuts down. So I started to observe the performance of the computer. The computer never shuts down while its plugged into a power source. However, when I use the computer with the battery it keeps working until the battery status reaches 30% or less and then just shuts down immediately. This is my observation. So I've been thinking about the problem. I thought its something with the battery which might be true or not. But I wonder if its also related to some errors in the battery status in the sense that it doesn't show the actual consumption of power from the battery and when it reaches 30 % it means that its empty. After shutting down, I tried to turn on the computer again but it keeps shutting down with the battery. Does anyone know something about this problem? Or if I need to reset some battery settings. Ideas are very much appreciated. Thanks.
