Processor maximum speed locked at 0.76 GHz

EDIT: The problem seems to have been fully resolved by doing a clean install of Windows 10.

Hello,

I use an AMD A6 processor on my Lenovo IdeaPad Flex 15D. Recently, my PC has been slow, and checking the Task Manager shows that the processor speed is only 0.76-0.78 GHz, while my processor's maximum speed is 2.00 GHz. The Resource Monitor says that my maximum frequency is 38-39% (0.76-0.78 GHz). This happens even when I'm in High Performance mode, and I've checked to make sure that the minimum and maximum speeds (in the power options) are set to 100%. I've also set the ATI Powerplay settings to Maximize Performance. The speed does not increase even when I'm running many programs at once.

Any help would be very appreciated.

I've noticed something interesting... The CPU speed in the Task Manager always seems to hang around 0.7-0.78 GHz, even when I'm not doing anything else on my laptop. Perhaps there's something that is not only preventing it from going above 0.78 GHz, but preventing it from going below 0.7 GHz. I have no idea why this is happening.

Hi,

You need to check with Lenovo Support, their on-line documentation and drivers, and

ask in their forums about any known issues.

    Hi,

    BTW check Control Panel - Power Options - the Processor settings in Resource Monitor

    will change depending on your settings as Power Saver, Balanced, or High Performance.

    Hi,

    I have exactly same problem with my Dell Inspiron 13Z (i7 5500U).

    Solution was easy... power adapter...

    My CPU was limited to 20% of power - switching between 0,3-0,7GHz and everything was damn slow.

    When I disconnect are reconnect my power adapter - everything was back in normal. I have no idea why system do this , connector on notebook side was connected wrong but who care? My battery was full...

    But - reconnect was solution. :o)

    Karel.

    Be sure to ask Lenovo Support by email and/or phone if possible.

    Use CPU-Z to get all the specs :

    Hi,

    As I said in the original post, I have already checked the Power Options and I have ensured that the High Performance mode uses 100% CPU minimum and 100% maximum. Still, going into High Performance mode does not increase the speed.

    I have taken my question to the Lenovo forums but so far I have not gotten a response. I will update this thread when/if I get a response.
