Aspire S7-391 Battery life terrible except when Task Manager running ?

I did a Window 8 Pro upgrade and all appeared to go well. But the S7 now drains the battery with a lifetime of about 3 hours or less.

 

The strange behavior is that the CPU is running high load with the fans sounding like jet engines ... but when the Task manager is turned on the CPU usage drops and battery lifetime increases to 6-7 hours!

 

This behavior is 100% repeatable and the CPU is running high before even logging in ... totally unexplainable by anyone to date and tech support said need to send the system for warranty repair where everything will be reset to "factory default"... which means I lose licenses for Windows 8 Pro, Office 2013... etc.

 

If anyone has seen or knows anything appreciate hearing from you.

 

This is not intermittent, it is 100% reproducible.

 

Task Manager or Resource Monitor Off – high CPU, loud fan and poor battery

Task Manager or Resource Monitor On – low CPU, silent, 6-7 hour battery life
