[G505s] Clock speeds stuck at 2.1ghz since BIOS 2.05 update

I have a Lenovo G505s with an A10-5750M APU

and since the BIOS upgrade from earlier this year (link to BIOS update)

my clock speed has not gone over 2.1ghz. During BIOS 2.03 my laptop

was able to reach 3.1ghz stable after power switched to the adapter

instead of battery, but now during BIOS 2.05 my processor clock speed

has been stuck (at 2.1ghz) and doesn not change with power plans of either

Windows 8 or Lenovos Energy Management Tool. Is any one else experiencing

this issue and/or have a workaround for this problem? 

 

Thank you for your time and hope to hear from the community. Cat Tongue

Wow. I actually found out why this was happening. AMD CCC seems to interfere with the Lenovo Energy Management and when i disabled AMD Catalyst Control Center at startup my PC was back at 3.2ghz stable. I also closed AMD Fuel Service but Im not sure if that was the root cause of it so if you have this problem try either one. Running Windows 8 btw.

Replace current bios download link with the correct filename of needed bios.

83cn33ww.exe is v2.03

83cn32ww.exe is v2.02

 

I often wonder why either a good question or concern is often overlooked on these forums.  Maybe this is not a popular model in the States?  Where are all the self proclaimed computer experts that seem to post all over the internet?  How about Lenovo Support Staff?  Guess it's a little early in the evening to be so critical, but I thought I would pass on this nugget of knowledge, especially considering the bios downgrade helped.
