4.1 General 4 Replacement Procedures General This chapter explains how to disassemble the computer and replace Field Replaceable Units (FRUs). It may not be necessary to remove all the FRUs in order to replace one. The chart below is a guide to which FRUs need to be removed in order to remove others. Always start by removing the battery pack, next, optional items such as the optional PC Card, then follow the chart downward removing only those FRUs necessary to reach the one you think is causing the computer to operate improperly.
Page 107
4 Replacement Procedures 4.1 General The example below shows FRUs to be removed before the Speakers can be removed and repaired or replaced. The Speakers are overlapped by the top cover that must be removed before it can be reached. The removable keyboard and display assembly in turn overlap the top cover.
Page 108
DANGER: Always use the lithium ion battery pack or backup battery that is authorized by Toshiba or compatible with the unit. Since other battery packs have different specifications, they may be incompatible with the unit, and may burst or explode.
Page 109
4 Replacement Procedures 4.1 General Before You Begin Look over the procedures in this section before you begin disassembling the computer. Familiarize yourself with the disassembly and reassembly steps. Begin each procedure by removing the AC adaptor and the battery pack as instructed in section 4.2. Do not disassemble the computer unless it is operating abnormally.
Page 110
4.1 General 4 Replacement Procedures Disassembly Procedures The computer has two basic types of cable connectors: Pressure Plate connectors Standard Pin connectors To disconnect a Pressure Plate connector, lift up the tabs on either side of the connector’s plastic pressure plate and slide the cable out of the connector. To connect the cable to a Pressure Plate connector, make sure the pressure plate is fully lifted and slide the cable into the connector.
