Resource Monitor

If you find that your computer is constantly jumping between Energy Saver and a higher clock when it should be relaxing, the culprit might be harder to find. In this case, I’d recommend checking out the Resource Monitor which can easily be launched by pressing the start button and searching for ‘Resource Monitor’. Once open, head to the CPU tab and then sort by ‘Average CPU’ in the Processes section. This will show you the average CPU consumption of each process over a 60 second period. This is helpful for finding CPU-hogging processes that intermittently steal processing power:

If you find any anomalies, track them down through Google and find out what they are related to and see if you can remove them safely. You can also right click in this list to ‘End Process’ and see if your processor is correctly entering Energy Saver mode. (Note: don’t worry about the perfmon.exe process, that’s the Resource Monitor!)

Preventing Programs and Processes from Starting at Boot

In many cases, naughty processes are the result of programs that have been set to start up when your computer boots — usually annoying updaters, quick-launchers, and toolbars do this without your permission. To prevent these things from starting up necessarily you can use a built-in utility. To launch, press start and search for ‘Run’. Once you have the Run window open, type ‘msconfig’ and press enter. Now go to the ‘Startup’ tab and uncheck the boxes of unnecessary items to prevent them from starting up during boot (be sure you know what you are disabling before you prevent something important from starting at boot).

With the above techniques, you should be able to root-out any offending programs or processes that might be preventing your Ultrabook from reaching the Energy Saver state, good luck!
