Page 60: Electrostatic Discharge
EMOVAL AND EPLACEMENT RELIMINARIES This chapter provides general service information for the Armada 1500c Series. Adherence to the procedures and precautions described in this chapter is essential for proper service. 4.1 Electrostatic Discharge A sudden discharge of static electricity from a finger or other conductor can destroy static-sensitive devices or microcircuitry.
Page 61: Generating Static
When grounding is not possible, use an ionizer to dissipate electric charges. Removing Batteries Compaq recommends that you remove all batteries from the computer before beginning the disassembly procedures. Failure to do so could cause damage to computer components.
Page 62 Preventing Damage to Drives To prevent static damage to hard drives: Handle drives gently, using static-guarding techniques. Store drives in the original shipping containers. Avoid dropping drives from any height onto any surface. Handle drives on surfaces that have at least one inch of shockproof foam. Always place drives with the PCB assembly-side down on the foam.
Page 63 Grounding Equipment Use the following equipment to prevent static electricity damage to the equipment: Wrist Straps are flexible straps with a minimum of 1 megohm +/- 10% resistance to the ground cords. To provide proper ground, a strap must be worn snug against the skin.
