2 REMOVAL SEQUENCEPRESARIO NOTEBOOK MAINTENANCE AND SERVICE GUIDE 1200XL SERIES Presario 1200 Series Models: XL101-XL113, XL115, XL118-XL127 Electrostatic Discharge A sudden discharge of static electricity from a finger or other conductor can destroy static- sensitive devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic device exposed to electrostatic discharge (ESD) may not seem to be affected at all and works perfectly throughout a normal cycle. Although it may function normally for a while, it may be degraded in the internal layers, reducing its life expectancy. Networks built into many integrated circuits provide some protection, but in many cases, the discharge contains enough power to alter device parameters or melt silicon junctions.
