Have you noticed that after bringing your Apple Mac back from sleep, it becomes sluggish and unresponsive. You have to reboot to get your mac back.
We have witnessed the same problem and it hits completely randomly.
Our diagnosis lead us to Activity Monitor, where upon checking the CPU use we found that kernel_task was using well in excess of 100%. Unusual.

We looked into it further, researched the internet. Checked everywhere for an answer and here's what we found.
None of these have worked for us, and people are still suffering.
- Headphone jack could be the issue - FALSE
- Disabling Bluetooth will correct the problem - FALSE, but did work for a while
- Google Chrome is the problem - FALSE, even after starting with a fresh browser it made no difference
- VLC Media player could be the issue - Untested, we use Movist. Highly recommended and better than VLC. Get it!
- Do a clean install - Untested, but lots of reports that this does not work.

So What is the answer you ask?
Well there is one. But.. we don't recommend it.
It seems version 10.9.1 is the affected OS that is causing the problem. The solution. 10.9.2. It's currently in Beta testing. It works, testers have reported that it has solved the problem and it can for you too.
But we don't recommend you install beta software as it is beta for a reason.
So what's the answer?
Unfortunately, for the time being you will have to either wait until Apple officially release the 10.9.2 update.
Or if you are really desperate to get your battery life and stability back on your laptop, your not a developer and you just can't wait, then you will have to search for OSXUpdCombo10.9.2.pkg
