     powering the screen accounts for a significant fraction of a laptop's power
     consumption.</p>
<p class="p">Most laptops have buttons on the keyboard (or a keyboard shortcut) that

<p class="p">If you don't need an Internet connection for a little while, turn off
     the wireless/Bluetooth card. These devices work by broadcasting radio
     waves, which takes quite a bit of power.</p>
<p class="p">Some computers have a physical switch that can be used to turn it off,
     whereas others have a keyboard shortcut that you can use instead. You can
     turn it on again when you need it.</p>
