Mobile Computing Monitoring battery power 117 Move the pointer over the power icon in the notification area, see "Finding your way around the desktop" on page 128 for more information on the notification area. A pop-up message displays the remaining battery power as a percentage. With repeated discharges and recharges, the battery's capacity gradually decreases. A frequently used older battery does not power the computer for as long as a new battery, even when both are fully charged. TECHNICAL NOTE: The computer drains the battery faster at low temperatures. Check your remaining charge frequently if you are working in temperatures below 50 degrees Fahrenheit. The computer calculates the remaining battery charge based on your current rate of power use and other factors such as the age of the battery. What to do when the battery runs low When the battery runs low you can: ❖ Plug the computer into an external power source and recharge the battery ❖ Place the computer into Hibernation mode and replace the battery with a charged spare (not included with your computer) ❖ Save your work and turn off the computer If you do not manage to do any of these things before the battery completely runs out of power, the computer automatically enters Hibernation mode and turns itself off. Hibernation mode keeps track of where you were, so that when you turn on the power again, you can continue where you left off. If you have Hibernation mode enabled (the default), the computer copies the details of your open programs and files to the internal storage drive before shutting down. For more information on using Hibernation, see "Hibernation mode" on page 84. Setting battery notifications You can set two notifications. Each notification can be set to alert you when a specified percentage of remaining battery power has been reached. You can also set the computer to enter Sleep mode or Hibernation mode or to completely power down when the notification goes off.
