    EXPANSION CARDS If, having read the following installation instructions, you do not feel confident about installing expansion cards yourself you may wish your supplier or service organisation to fit the card for you. The only tool required is a small cross-head screwdriver. Warning Warning Never carry out any work on the equipment with power applied.

  • Page 35: Troubleshooting

    TROUBLESHOOTING This chapter offers advice if you suspect a fault with your computer. It is concerned mainly with problems caused by the computer itself, problems more often arise from other sources such as your operating system or application software. It must also be remembered that it can be very easy to leave off or dislodge cables and connectors inside the computer when fitting expansion cards, or upgrading the motherboard, or indeed anything that may require temporary removal of the system cover.

    T r o u b l e s h o o t i n g Power-on self-test (POST) Whenever the computer is turned on, the power-on self-test (POST) routine tests various hardware components, including memory, and compares the actual configuration of the computer with that recorded in configuration (CMOS) memory.

    SYSTEM BIOS AND SETUP The basic input-output system (BIOS) is permanently encoded in an area of read-only memory (ROM). It can be modified or upgraded if necessary, but this is recommended to be undertaken by an authorised engineer. It requires specialist software. BIOS Setup is a utility within the computer BIOS.

  • Page 67: Antistatic Precautions

    ANTI-STATIC PRECAUTIONS Static electricity can cause permanent damage to electronic components. You should be aware of this risk, and take precautions against the discharge of static electricity into the computer. Static electricity can be generated by moving on a chair, brushing against desks or walls, or simply walking across an ordinary carpet.

  • Page 68

    A n t i - s t a t i c p r e c a u t i o n s ♦ Handle static-sensitive items with extreme care. Hold expansion cards and add-on components only by their edges, avoiding their electrical contacts. Never touch the components or electrical contacts on the motherboard or on expansion cards.

  • Page 69: Cleaning And Transporting

    CLEANING AND TRANSPORTING Cleaning the computer Do not use solvents or abrasives, they might damage the system unit surfaces. Do not use aerosols or sprays near any part of the system, in particular, air vents or grills, ports, or removable-media drives, as microscopic droplets can remain in the air for some time and then be sucked in when you switch on and cause irreparable damage.
