I get the following error when I shutdown or restart the computer after disabling "Smart power-saving CPU" in the Energy Management Settings:
Energy Management.exe - Application Error
The instruction at 0x80001700 referenced memory at 0x80001700. The memory could not be written.
Click on OK to terminate the program.
After rebooting, the smart power-saving CPU option is still enabled, so I can't disable the smart power-saving cpu option.
How can I permanently disable this setting?
I have a G470 with Windows 7 64bit with the latest drivers and BIOS (my version numbers are even greater than the ones available from the consumersupport site)
PS.
I want to disable Smart power-saving CPU because of another bug that I confirmed was caused by this setting: Programs would become unresponsive after 3 or so minutes of inactivity (not moving the mouse or typing anything). For example, itunes would suddenly stop playing in the middle of a song. Firefox (or any other open program) would appear to hang when I go back to my laptop after being away. Those programs would respond again after a painfully long time. All I can do is just move my mouse and switch windows to other unresponsive programs.
This problem went away after I disabled smart-power saving CPU and also smart power-saving hard disk. For weeks everything was working properly. but then I encountered again this "unresponsiveness after minutes of inactivity" problem and I discovered that the "smart power-saving CPU" setting was reset/re-enabled and I could not disable it anymore.
Please help. I need a fix for just one of the two mentioned bugs.
Thanks.

You may uninstall the existing power management software and install the previous version software.
Download the previous version software from the mentioned below web link.
