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.

BTW - I had a similar problem on a Toshiba Satellite - it was fixed by the following Windows 8.1 bug workaround:
Thanks for posting that, I'll check it out. Occasionally my laptop does actually go back to the 0.78 limit, and I have still been able to fix it by removing the battery, but that's annoying because it resets the BIOS options...

My friend suggested that I take out the battery, plug the laptop in, and run it. Somehow (it sounds like it resets the drivers or something) this fixed the problem. I still can't believe it. Anyway, thanks for your suggestions!
Since that worked it probably indicates Lenovo has some sort of Power Options / Power Management
control in place which I have thought all along. And/or there was some sort of hardware or software
glitch which that cleared. If you put the battery back in does do the same thing? (It may even take
letting it sleep or hibernate once to energize that change if it is going to do so.)
The Lenovo Forums is likely to have others that have/had the same issue.
Glad to have helped. Sounds like you did some very good troubleshooting!
Moving everyday, going further on,

Yeah, when I put the battery back in, it is still fine.
