Problem with Speedstep on Laptop - Lenovo L412

Hey guys, I own a Lenovo L412, just purchased two weeks ago, with an i-3 370m processor. Initially, the laptop was installed with W7 Pro 32bit, and speedstep worked perfectly fine, where when the load was high, it would show 2.4MHz running, and if low power around 796MHz, it would range between there. However, I wanted an upgrade to Pro 64bit, so I did a clean install, installed all the normal Windows Updates, and now speedstep does not seem to be working, it is always kept at a constan 2.4MHz, running at the top frequency. I have All Meter CPU and CPUZ for monitoring, this has been going on since I did the full reinstall of the OS. I have made changes to the BIOS, and nothing gets the Speedstep to work. I have tried all power plans, even changing the advanced setting, multiple things with battery in and on AC, no avail. What can I do? I mean it shows no problems yet, but I find it a problem, when constantly running at full 2.4MHz. In CPUZ, the Bus Speed shows 133.0MHz w/ Multiplier being 18.



I fresh installed from a digital download copy, and used the MS Store program to make a bootable USB.



Here is a screen shot of what I am talking about:



ImageShack - Online Photo and Video Hosting



It always stays at that frequency, not changing no matter what power plan I use.

Platform Power Management Capabilities:Supported Sleep States

Sleep states allow the computer to enter low-power modes after a period of inactivity. The S3 sleep state is the default sleep state for Windows platforms. The S3 sleep state consumes only enough power to preserve memory contents and allow the computer to resume working quickly. Very few platforms support the S1 or S2 Sleep states.

S2 Sleep Supported false

S3 Sleep Supported true

S4 Sleep Supported true

I have already contacted Lenovo, and they say that I would need to purchase their "Lenovo Upgrade Discs", is there anyway for me to do it without a hitch like this, without having to shell out $60-70? Or anyway to fix this issue?

Did you already download and install the Power Management driver? If you already have, then try re-install them over what is currently installed.
