Energy Management on Win7 x64, Problems with WiFi

2010-04-10, 15:40 PM

Hey guys, hope you can help me.

 

I'm using Windows 7 64 bits and have Lenovo Energy Management installed. I had Super Energy Saver profile activated and everything was fine, but when I changed to Performance profile, my Wireless card deactivated. I tried uninstalling and reinstalling the program, but it didn't work. I also tried to activate it from Windows, but didn't work either. The only thing that works is activating Super Energy Saver profile and selecting there to activate the wireless card.

 

Is there any chance to get back to normal state? Do I have to set Super Energy Saver always to have wireless connectivity?

 

Sorry for my poor English

After rebooting, the problem was solved

I have Z50-70 series, i have this problem too. I used the version from the site http://support.lenovo.com/us/en/products/laptops-and-netbooks/lenovo-z-series-laptops/lenovo-z50-70/downloads/DS100548 it says that it support windows 7 but still ACPI\VPC2004 in device manager "unknown device". If I try to install a different version of energy manager my wireless does not work.

 

Lastly, I installed energy management and ;

1- device seems "unknown device"

2- my wireless power is too low, in office all laptops lenovo seems full but my wireless power seems 1 or 2 bar.

 

waiting for your help

 

Thank You.
