cannot disable power management for network card in windows 7
Posted on 2011-09-26
When I try to disable the option "Allow the computer to turn off this device to save power" for my wired network card in the Power Management tab, it always comes back to enabled by itself if I go back to verify its settings.
Any idea what could be setting it back on automatically, or how to manually force it to off ? I tested the same thing on other pc's and the setting stays disabled, like it should.
Environment: Windows 7 Pro 64 bits, all updates installed, Dell Vostro 430 Desktop.
