I've been noticing some issues with my MacBook for a while now. Firstly, kernel_task sometimes takes over extreme amounts of CPU and the whole computer starts acting slow even when I'm not using it for any heavy tasks.
Note that this is a 15" MBPro 2015, all specs maxed out.
Fans are also often at full speed for seemingly no reason (just browsing the net) but that has been going on forever since I bought it, and I heard that is relatively normal for those MBPros.
But last night the weirdest thing happened. I closed the lid and went to sleep. Several hours later in the morning, I was awoken to my MacBook fans going on at 100%.
I got up to check it out and the bottom plate was pretty hot and fans still going at 100%. I opened the lid and I couldn't get it to turn on. The screen would not show anything no matter how long I waited and how many keys I pressed.
I ended up force shutting it down (holding down the power button).
Any idea what could be causing this? Is there any way I can try to figure out the problem, or is taking it to Apple for repair the only option?
