Remember the following when you are charging the battery: 0 Use only the AC adapter that comes with the Equity LT-386SX. Using a different adapter can damage the computer and/or the battery pack. Q Charge the battery for at least eight hours. If you charge the battery for short periods, it runs low sooner. The length of time the battery provides power after being charged depends on how you are using the computer. A fully charged battery provides approximately one to three hours of use. If you are working with a program that makes extensive use of the hard disk or if you are using the diskette drive, you may need to recharge the battery sooner. To increase the amount of time you can operate the LT-386SX using the battery, follow these guidelines: CI Lower the brightness of the backlight to its lowest readable level. Use the brightness lever on the right side of the screen. Q Select a clock speed of 8 MHz. In the SETUP menu, choose the 8 MHz option for CPU clock setting. Or, during operation, you can hold down Ctrl and press left Shift and F simultaneously to change the computer's clock speed. (The status indicator bar displays the current clock speed.) 0 Using the Standby mode setting in SETUP, turn off the backlight to the LCD when you are not using the keyboard. 0 Using HDDPSAVE, turn off the hard disk drive when you are not using it. (The HDDPSAVE utility program is described in "Turning Off the Hard Disk," later in this chapter.) Remember that powering up the hard drive uses power, so set a realistic time period for the power to be turned off. Using the Equity LT-386SX 2-3
