    Intel Processor is running high after upgrading Windows


    I have upgraded my Sony Vaio E series laptop (VPCEG38FG) from Windows 7 Home Premium to Windows 8 Pro and now I see that the Intel Processor is running high 3.00GHz all the time (monitoring it through Intel software) causing the laptop to run out of battery quickly and the fan is on all the time.

    Intel(R)_Core(TM)_i5-2450M_CPU_@_2.50GHz

    Does anyone know what is wrong or what to do?

    What power profile do you have? check your power options, if its high performance, change it to balanced or power saver.
    If its still not going down, go to:
    Control panel > power options > change plan settings (on the right of the profile) > change advanced power settings

    Go to the bottom and look at the "Processor power management: Minimum processor state" and make sure its at 1%.

    If it still not going down, you will probably have to enter the laptop's bios, and make sure the C1E state or intel speed step is enabled within the processor settings.

    It really depends what programs are running.
    Check Task Manager and sort the CPU tab with the highest entries above to see more details.

    Thank you for the suggestions but neither one worked.

    I had the power option set to Balanced. I changed the Minimum processor state to 1%.

    I could not find the C1E state or Intel speed step in the Sony BIOS.

    As I said, I am running Windows 8 Pro now and this has started after the upgrade. It was fine under Windows 7. This behavior is immediately after starting the Sony laptop and stays like that all the time till the battery runs out in less than an hour. This is a new laptop which was just purchased recently in Sept.

    No programs or applications are running in the background.

    Please help me sort this issue out.
