Chosen Solution
Hi there, I was wondering if anyone would have the answer to my really strange situation. Basically, every time I want to turn my MacBook on, I either have to disconnect the battery and then plug it back in and then it will boot up as normal, or I have to reset the SMC every single time and then it will turn on as normal. When it turns on, the built-in display works for less than a minute and then randomly turns off and then will not turn on again until the machine is shut down and then powered on again. if connected to my TV via HDMI cable, there is nothing wrong with the picture at all. Also, when I press on the chassis around the keyboard, the display on my TV flickers and even randomly disconnects, I’m not sure if this is relevant or not, I just thought i should include it. Also, when the MacBook powers on, it is fine for a bit but then must be plugged into power otherwise it will go to sleep. I don’t think this is a battery issue because I have tried two batteries and the problem still persists. I’m fairly sure this may be a logic board issue, as I have bought a new display cable and the issue persists. I read somewhere that it may be an issue with a water damaged chip but everything seems to look fine on the board. If someone could please point me in the right direction I will be forever grateful! UPDATE: This is a picture of coconut battery:
When I hold D while starting up, it says “starting internet recovery” and then displays this error:
What I can tell you is batteries do have a lifespan! Your battery is just old! It’s the original battery your system had (or you swapped it out with other used battery). Note the your batteries cycle count is getting very close to the batteries limit of 1,000 cycles (currently 884) and also consider the age limit is around 2,000 days which is just over three years (yours 3,253 days old). Determine battery cycle count for Mac notebooks Bottomline your issue is most likely a worn-out battery. What is hard to explain is the why! Lets look at a mind model of a bunch of containers are water. The top container is your charger pouring into a second container via a pipe at the bottom. This is at a max rate of 5. Now the second container has a pipe as well that has a max rate of 10. So as long as the tank was full the time it will take will be X, but if the tank is half full then its one half of X and clearly if the container is almost empty then it won’t take long for the water to become a trickle of what the upper tank is able to supply a rate of 5. So how does this translate to your condition? The battery is the second container but it doesn’t have the ability to hold the amount of energy you require to run. So it starts up as there is enough to get things going but not sustain the system, hence your system shuts down. Time to replace the battery with a fresh one!
