Setting Power Management for an Intel WLAN adapter installed in a system with Microsoft Windows XP* can be misleading if the user overlooks the information in the Description box.
The power management setting can actually be thought of as power savings mode. There are six levels of power savings, numbered 0 through 5. Level 5 provides the greatest amount of savings (i.e. uses the least amount of power, and thus, is less taxing on the battery). Level 0 disables power savings mode. An advantage of disabling power savings mode is that it provides the greatest Wi-Fi network performance.
Armed with this knowledge, the power management setting would look like this.
Remember, if you think Power Management = Power Savings Mode, then
5 = maximum power savings
0 = maximum WiFi network performance
Default (Use default value) = mode setting based upon power source, where
if power source = battery
power savings mode = 3
else (power source = AC)
power savings mode = 0
For Microsoft Windows 7*, the user interface is different. The Power Management configuration is no longer accessed through the Device Manager, but rather through the Control Panel Power Options.
The slider is gone, replaced with drop-down lists, which most users should find easier to understand. The configuration choices are consistent with the Microsoft Windows XP* discussion above.
