4.1 General 4 4 Replacement Procedures 4.1 General This section 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. Refer to the example on the following page.

The LED / button board is overlapped by the top cover which must be removed before the LED / button board can be reached. The top cover is in turn overlapped by the expansion memory, HDD, FDD, keyboard and CD-ROM / DVD-ROM drive. Always starts the disassembly process by removing the battery.

DANGER: 1. 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. Heating or disassembling the battery pack could cause leakage of alkaline solution. Throwing the battery pack into a fire could cause the battery pack to explode. The power supply, FL inverter and other components carry high voltages. To avoid the risk of electric shock when you need to turn on the power of a partially disassembled computer to check its operation, be very careful not to touch connectors or components. Also, do not disassemble individual components in firstlevel maintenance. 2. WARNING: To avoid the risk of electric shock or other injury: 1. Always turn the power off and disconnect the AC adaptor from the power source. 2. Remove any metal jewelry or accessories such as necklaces, bracelets, or rings. Batteries in the computer retain an electrical charge so there is danger of electrical shock even when the computer is disconnected from an AC power source. 3. Never work with wet or damp hands. 4. The computer contains sharp edges and c

Turn the computer upside down and remove two M2.5Ч4 security screws securing the CPU compartment cover. Figure 4-28 Removing the CPU compartment cover screws 2. Remove the CPU compartment cover. Figure 4-29 Removing the CPU compartment cover 4-22 Satellite A30 Series Maintenance Manual 4.9 CPU 4 Replacement Procedures 3. Remove four M2.5Ч5 black screws securing the heat sink. They must be unscrewed in catty-corner order (i.e. lower-left first, then upper right second, and so-on.) Figure 4-30 Removing the heat sink screws 4. Remove the heat sink. Figure 4-31 Removing the heat sink CAUTION: If you remove the heat sink, you should use the CPU grease tool to remove the grease on the CPU and heat sink. Reapply fresh grease before replacing the heat sink. 5. Turn the cam on the CPU socket with a flat-blade screwdriver so that the notch on the cam is aligned with the "open" side of the CPU socket to unlock the CPU.

Gently lift out the CPU. 4.9 CPU Figure 4-33 Removing the CPU Installing the CPU To install the CPU, follow the steps below. CAUTION: If you remove the heat sink, you should use the CPU grease tool to remove the grease on the CPU and heat sink. Reapply fresh grease before installing the heat sink. 1. Make sure that the notch on the cam is aligned with the open position. Figure 4-34 Unlocking the CPU cam 2. Seat the CPU to align the triangle mark on the CPU with the upper right corner of the socket if the front of the computer is facing your body. Make sure the alignment is exact to avoid damaging pins on the CPU. Figure 4-35 Aligning the CPU triangle 4-24 Satellite A30 Series Maintenance Manual 4.9 CPU 4 Replacement Procedures 3. Press the CPU softly with your fingers and turn the cam on the CPU socket to the closed position with a flat-blade screwdriver to secure the CPU. 4. Seat the heat sink over the CPU making sure that the heat sink is oriented so that the two knobs in the CPU compartment secure it. Figure 4-36 Inserting the heat sink 5. Secure the heat sink with four M2.5Ч5 black screws. The screws must be put tightened in a catty- corner order (i.e. lower-left first, then upper right second, etc.) Figure 4-37 Tightening the heat sink screws 6. Replace the CPU compartment cover.
