How To Limit Your Connection

Limit Your Connection  (Laptop's)

Simple Steps for Limit Your Internet Connection:

When you aren't actively using your notebook's Wi-Fi, Bluetooth, WWAN, or other wireless connections, turn the radios off (via the hard switch, if your PC has one, or using the appropriate utility), so they don't run down the battery while they keep searching for a signal.

Also, use USB-attached devices sparingly while you're mobile.
