Run the diagnostic tests explained in Chapter 2 of this manual to identify the FRU that has probably caused the system failure. Perform only the required machine operations. Use only the disassembly and reinstallation procedures described in this manual. Place the removed components in a safe place away from the computer so that they are not damaged or get in the way of you doing your work. Normally, a number of screws need to be removed or replaced during disassembling. Place the removed screws in a safe place so that you can easily find the right screws for the right components. When assembling the computer, use the specified screws to fasten the parts to the specified locations. See the appropriate explanations and figures for screw sizes. To avoid personal injury, use care to handle components that have sharp edges or corners. After you have replaced a FRU, check that the FRU works correctly to ensure normal computer operation.
Disassembly Procedures The cable connectors come in these two basic types: Pressure plate connectors Normal pin connectors
To remove a pressure plate connector, pull up the tabs on either side of the connector's plastic pressure plate and gently pull the cable out of the connector. To reconnect the cable to the pressure plate's connector, raise the pressure plate up to a satisfactory height and slide the cable into the connector. Secure the cable in the correct position by pressing down the sides of the pressure plate so that the plate is flush with the sides of the connector. Grasp and pull the cable gently to check that the cable is connected firmly. If the cable comes off the connector, reinsert the cable by raising the pressure plate up to a satisfactory height. Normal pin connectors are used for all the other types of cables. These connectors can be installed or removed by simply inserting them or pulling them out.
Assembly Procedures You have to reassemble the computer after you have disassembled the computer and fixed the component that caused the problem. When reassembling the computer, keep the following general guidelines in mind: Take your time to carry out the suggested instructions completely. Hurried reassembly can often cause problems. Check that all the cable and connectors are fastened securely. Before securing the FRUs or other parts, check that the cables are not caught by the screws or FRUs. Check that all the latches are closed securely. Check that all the required screws are used to secure the FRUs. Using wrong screws can damage the threads or heads of the screws or does not ensure that the FRUs are secure.

After installing a FRU, make sure that the FRU and computer work normally.
Tools and Equipment For your safety and that of other people in the working environment, it is strongly recommended that you use electrostatic discharge (ESD) equipment. The proper use of this equipment will ensure successful repair work and reduce the costs for repairing damaged components. The equipment and tools required for disassembly and reassembly are: One 2 mm Phillips screwdriver One 4 mm flat-blade screwdriver Torx screwdriver Tweezers (for pulling out screws) ESD mats (for the floor and work desks) An ESD wrist strap or heel grounder Anti-static carpets or flooring Air ionizers (for highly electrostatic sensitive areas) A plastic card (in credit card size)
Screw Tightening Torque To secure screws, follow the torque values listed below. Over tightening can damage components and screws. Under tightening can loosen the screw or cause screws to come off, which may result in short circuits or other damage. M2 (2 mm) M2.5 (2.5 mm) M3 (3 mm) M2.5x4 PSP TITE screws 0.22 Nm (2.2 kgfcm) 0.36 Nm (3.5 kgfcm) 0.51 Nm (5.0 kgfcm) 0.204 Nm (2.0 kgfcm)
M2.5x6 GIZA TITE screws 0.36 Nm (3.5 kgfcm)
Colors of Screw Shanks For easy identification of the correct screws, the screw shanks are colored according to their lengths, as follows: Screws of an even-numbered length Brown Screws of an odd-numbered length White Screws of a special length Black Screws of a special length are those of a length having decimal places, such as 2.5 mm and 2.6 mm.
Symbols of Screws on the Computer Body For easy maintenance, the screw types are shown on the computer body as symbols. A symbol consists of a letter representing the screw type and a numeral representing the screw length. Screw type Bind screw Flat-head screw Super flat-head screw Tapping screw Other screws Letter B (stands for bind) F (stands for flat-head) S (stands for super flat-head) T (stands for tapping) U (stands for unique-pan head screws, studs, etc.)
Symbol examples 6 mm bind screw Bmm bind screw Bmm stud U5 (The numeral represents the rounded length of the threaded portion regardless of the entire stud length.)
