One way to conserve power on the computer is to close the display when the computer is not in use. When you close the display and an external monitor is not connected, the computer's display shuts off and, depending on how you set the Lid Close option on the Power screen in the system setup program, the computer may enter suspend mode (standby mode in Windows 98, Windows 2000, and Windows Me).
Some PC Cards may not operate correctly after resuming from S2D mode. If you encounter problems with a card, remove and reinsert the card. NOTE: Dell creates an appropriately sized S2D file before shipping the computer to you. Use the Suspend-to-Disk Utility to remove the file, to increase the size of the file, or to add the S2D file if you removed it. For information on creating a S2D file, see "Suspend-to-Disk Utility.
l l l Power Meter — allows you to view the percentage of battery life remaining when your computer is operating on battery power. If your computer is operating on AC power, the computer displays a message. Advanced — allows you to display the Power Meter on the Windows 98 taskbar and to display a password prompt when the computer resumes operation from standby mode. Advanced also allows you to define the action of the Power buttons. Hibernate — allows you to enable hibernate mode in Windows 98.

When you activate standby mode (known as suspend in Microsoft® Windows NT®), the computer can remain in standby mode on battery power for approximately one week (if the battery was fully charged before activating suspend or standby mode). If you are going to store the computer, disconnect all devices and turn off the computer. Remove the battery when you store your computer for an extended period of time. A battery will drain when not in use during prolonged storage.
3. Remove the battery from the battery bay. Close the computer display and turn the computer over. Slide the battery bay latch to the unlock position (see Figure 2), causing the battery to pop up slightly on one side. While keeping the latch in the unlock position, pivot the battery up and out of the bay. Release the latch. Figure 2. Removing a Battery 4. Position the new battery as shown in Figure 2, and lower the outside edge of the battery into the battery compartment.
l l l l If one indicator lights up, the battery has 1 to 25 percent of its charge remaining. If two indicators light up, the battery has 26 to 50 percent of its charge remaining. If three indicators light up, the battery has 51 to 75 percent of its charge remaining. If four indicators light up, the battery has 76 to 100 percent of its charge remaining.
Do not dispose of these batteries along with household waste. Contact your local waste disposal agency for the address of the nearest battery deposit site. About Battery Power You automatically conserve battery power each time you connect the computer to an electrical outlet. The battery is even being recharged when you use AC power. The battery's life expectancy is largely determined by the number of charges it receives, so use an electrical outlet to run the computer whenever possible.
