4.1 General 4 Replacement Procedures Assembly Procedures After you have disassembled the computer and fixed or repaired the problem that was causing the computer to operate abnormally, you will need to reassemble the computer. Install all the removed FRUs following the steps described in the corresponding sections in this chapter. While assembling the computer, remember the following general points: • Take your time, making sure you follow the instructions closely. Most problems arise when you get in a hurry assembling the computer. • Make sure all cables and connectors are securely fastened. • Before securing the FRU or other parts, make sure that screws or the FRU will pinch no cables. • Check that all latches are closed securely in place. • Make sure all the correct screws are used to secure all FRUs. Using the wrong screw can either damage the threads on the screw or the head of the screw and may prevent proper seating of an FRU. • When using new parts with double-side tapes, peel off the separators. After installing an FRU in the computer, confirm that the FRU and the computer are functioning properly. Tools and Equipment The use of Electrostatic Discharge (ESD) equipment is very important for your safety and the safety of those around you. Proper use of these devices will increase the success rate of your repairs and lower the cost for damaged or destroyed parts. The following equipment is necessary to disassemble and reassemble the computer: • One Philips screwdriver with type 0 bit (for S-THIN HEAD screws) • One Philips screwdriver with type 1 bit (for screws other than above) • Tweezers (for lifting screws) • ESD mats (lay on work table or floor) • An ESD wrist strap and heel grounder • Anti-static carpet or flooring • A pair of needle-nose pliers • Air-ionizers in highly static sensitive areas • Antenna coaxial cable disconnector PORTÉGÉ R500 Maintenance Manual (960-634) [CONFIDENTIAL] 4-5
