Turn off or remove devices that you aren’t using. Many universal serial bus (USB) devices use power just by being connected. If you use a USB mouse, you can save power by disconnecting the mouse and using a touch pad or tablet pen. If you use a USB flash drive, unplug it when you’re not using it.

Personal Computer Memory Card International Association (PCMCIA) cards and integrated wireless devices also use power. If you don’t need these devices while you work, turn them off.

These power-saving tips can help you get the most use from a single battery charge and avoid the inconvenience—and the potential embarrassment—of having a dead battery.
