Chapter 2: Power and Your Computer
Digital HiNote VP 500 Series 2–13
Screen Brightness
The brighter the LCD display screen, the shorter the battery run time. Avoid setting the screen
brightness higher than necessary. This will extend battery run time.
The Floppy Disk/CD-ROM Drive
The floppy disk drive (FDD) and CD-ROM drives consume a large amount of battery power.
In order to maximize battery run time, use the FDD/CD-ROM only when necessary.
PC Cards
PC (PCMCIA) Cards will also tax your battery power significantly reducing run time. When
operating the notebook on battery power, use PC Cards as little as possible. When you finished
using your PC Card, eject it from the PC Card slot. This extends battery run time.
The Serial/ Infrared Port
The computer serial ports will draw some power if Enabled, even though no serial device is
connected. If you are not using a serial device, you can turn the COM port off through the
BIOS program. This will assist in conserving battery power. Please see Chapter 3 for a
complete discussion on enabling and disabling the notebook’s ports.
AC Power
The most obvious way to conserve battery power is to avoid using the battery when there is an
available AC power source. The AC Adapter is lightweight and compact, so it is very
convenient to bring while traveling. By using the AC Adapter as much as possible, you can
ensure you will have a charged battery whenever you really need it.
