Making your battery last longer

Following are some practical suggestions that you can do to maximize the operating time of the battery:

• Enable Power Management, and choose a power plan that saves power. A power plan is a collection of hardware and system settings that control how the device manages power.

• Decrease the display brightness to the lowest comfortable level (press Fn + 4).

• If you don't work in low light settings, disable the keypad backlight. Clear the Enable Keyboard backlight to completely disable the backlight. See Display settings: adjusting the backlight.

• Shorten the length of time before the operating system turns off the display.

• Change your Sync settings. Go to Settings / Accounts / Sync your settings and deselect any items that do not need to sync across your Windows devices.

• If you use a USB flash drive, unplug it when you are not using it. Many USB devices use power just by being connected.

• Turn off the wireless radios when you are not using them. See Using wireless networks.

• Turn off Empower modules if you will not be using them for a prolonged period. See Using Empower modules.

• Turn off the screen rotation. See Display settings: rotation lock.

• Turn off the device when you are not using it. See Turning off the device.
