Hello there,
I don't know how to better name this thread because I have multiple problems that may be due to the same thing. Last year I succesfully updated to Yosemite and had everything working thanks to the http://www.tonymacx86.com/mountain-...n-lion-guide-2012-sony-vaio-s-series-svs.html and RehabMan for his nice support.
Sleep & Wake worked properly and PowerManagement was fine.
At some point things got weird. Suddenly my laptop started to have a problem where sometime when I boot into OS X the fans spin very loud and I have a process 'kernel_task' using a lot of CPU power. It drops when I connect a mouse adapter for example.
When this problem occurs and I shut down my laptop, it restarts. And again kernel_task has high CPU usage. After 2-3 'shutdown' (restarts) CPU usage drops again and I can shut down properly.
Also my Sleep & Wake doesn't work anymore. I can sleep but wake doesn't work anymore (some rare cases where it actually wakes).
After a clean install Sleep & Wake worked again for a couple of time but then it became the same. No sleep/wake and high cpu because of kernel_task.
Now after the update to El Capitan I even have a new process using a lot of CPU: UserEventAgent
What's going on here?!
- kernel_task with high CPU usage
- UserEventAgent with high CPU usage
- Shutdown sometimes restarts laptop
- Sleep/Wake doesn't work
