What should I know about using power save mode on my laptop computer?Share & Print
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)
- Click Start > Settings > Control Panel.
- Double-click Network Connections.
- Right-click the wireless connection and click Properties.
- Click Configure.
- 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.
