What should I know about using power save mode on my laptop computer?

Power Save Polling (PSP) mode is a feature that provides extended battery life for laptop computers. The mode requires coordination between an access point (AP) or router and the Wi-Fi adapter. Some APs or routers may not implement the feature correctly or completely, which may cause:

• Loss of your Wi-Fi connection
• Inability to initiate a Wi-Fi connection
• Poor Wi-Fi connection

Using battery power may make these problems more noticeable.

An easy workaround for this issue is to put the Wi-Fi adapter into continuously aware mode (CAM) in order to disable the PSP feature. There are two ways to do this:

Wireless Wi-Fi connection utility

Click Advanced > Adapter Settings > Advanced tab.

• Windows XP: Select Power Management, uncheck Default/Auto and move the slider to Highest/Maximum Performance.
• Windows 7 or 8: Select Transmit Power, change Value to 5 (highest).

Network control panel applet (NCPA)

1. Click Start > Settings > Control Panel.
2. Double-click Network Connections.
3. Right-click the wireless connection and click Properties.
4. Click Configure.
5. Click the Advanced tab.

• Windows XP: Select the Power Management setting, uncheck Default/Auto and move the slider to Highest/Maximum Performance.
• Windows 7 or 8: Select Transmit Power and change Value to 5 (highest). If the slider is already at Highest/Maximum Performance, move the slider to another setting and then back to Highest/Maximum Performance.

NOTE: Using these methods may cause Bluetooth devices to not receive signals. Please contact your computer manufacturer for additional information.
