Random crashes and slowdown
Hi everyone,
I recently got a lot of troubles with my MBP, some random crashes especially when looking videos or opening a lot of programs. But it also happens after the computer exits sleep mode.
Now, when I launch it, I need to press the power button until the loading bar appears. If not, the computer shut down after the "bong".
I ran a Etrecheck analysis and I always have the "battery failure" (Error 79) corresponding to the crashes. Why ? It also happens when battery is unplugged.
Here is the Etrecheck report :
Is this a good question?

Lets try a simpler and free tool to check your battery. download this gem: coconutBattery
Take a screenshot of the main screen so we can see it fully and post that into a new answer window, then do an update to your question.
Also check your MagSafe adapter and its connections. Follow this Apple T/N: Apple Portables: Troubleshooting MagSafe adapters

According to coconut battery, everything is alright, battery's fine with a bit less than 400 cycles.
The biggest problem is : when I boot the computer, kernel_task is already at more than 240% of CPU using.
Yesterday I created a new admin account and the problem vanished. But here it goes again.
I tried smc and pram reset with no effect. Reinstalling the OS too. I'm starting to run out of options.

OK so yesterday, I cleaned up the computer, and tried to reinstall Mavericks, not Sierra.
Kernel_task vanished so I was able to use my computer normally. Before sleeping, i closed my MBP so it can be in sleep mode. When I took it back, the computer was completely shut down.
The same issue as before occured again, I need to press the power button until the loading sign appears so that the computer can boot normally.
And again, this stupid kernel_task is eating more than 300% of the CPU activity. This is seriously p****** me off.
The computer is not overheating, the battery's fine, I tried 3 different OS, safe mode is affected too, tried VRAM/PRAM/SMC reset. I've tried all.

I am experiencing the exact same crashes. I have replaced both the battery and SSD. So it couldn't be a virus? Did you ever solve the problem?
