The procedures are divided into two subsections: The Customer Removable Parts and The Service Removable Parts. The first subsection explains which parts may be removed by the customer/owner, and the second subsection explains which parts should be serviced by the technician. The Customer Removable Parts Serial Number Report your Notebook's serial number 1 to Compaq when requesting information or ordering spare parts. The serial number is located on the underside of the Notebook as shown below. Å WARNING: Prior to servicing your Notebook, disconnect AC power cords and external devices, and remove the battery pack and any PC Cards. Failure to disconnect electrical devices may cause damage to the Notebook and loss of human life. PRESARIO NOTEBOOK MAINTENANCE AND SERVICE GUIDE 1400 SERIES REMOVAL SEQUENCE 1 Presario 1400 Series Model XL240, XL241, XL242, XL244, XL245, XL246, XL247, XL250, XL340, XL341, XL342, XL343, XL344, XL345, XL346, XL350, XL352, XL355, and XL356 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 that has been exposed to electrostatic discharge (ESD) may not seem to be affected and work perfectly throughout a normal cycle. Although the Notebook may function normally for a period of time, it may have been degraded in the internal layers, reducing the 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. Generating Static The table below shows activities that generate static electricity and the associated level of electrostatic voltage.
