Introducing your Computer:

  • Unpacking: Details what to expect in the box, including the system unit, power cords, and documentation. Advises keeping packaging for transport and noting manufacturer data for service needs.
  • Energy-efficient features: Complies with "Energy Star" program, supporting System Management Mode (SMM) and Advanced Power Management (APM). Features VESA BIOS Extensions for monitors supporting DPMS.

Getting Started:

  • General advice: Recommends siting the computer in a stable, dry environment away from extremes of temperature and sunlight. Emphasizes ergonomic considerations for monitor and keyboard placement and ensuring adequate ventilation.
  • Connecting the components: Provides a step-by-step guide to connecting the system unit, monitor, keyboard, mouse, and peripherals. Stresses the importance of connecting in the correct order and ensuring power is off.
  • Turning on and booting the computer: Explains how to power on the system using the POWER button, the function of the power indicator, and the power-on self-test (POST). Describes the boot sequence, looking for a system diskette or booting from the hard disk.
  • Starting the computer for the first time: Mentions a legal message regarding software use that requires user acknowledgement.
  • Why your computer may seem to stop working: Explains the energy-saving standby mode where the screen may blank and the processor slows down, which is reactivated by keyboard or mouse input.
  • Turning the power off: Outlines a checklist before shutting down, including saving files, logging out of networks, closing software, and turning off peripherals first. Details the power-off procedure via the POWER button.

Using your Computer:

  • Using the 3.5" diskette drive: Describes the drive's capacity (720 Kbytes and 1.44 Mbytes), how to insert and remove diskettes, and the importance of write-protection.
  • Using the CD-ROM drive: Explains its capability to retrieve data from CD-ROMs and play audio CDs. Notes the dependence on operating environment software and the importance of not moving the computer while a CD is in use.
