2 - 2 Overview

Locking collar sockets for ribbon connectors

To release these connectors, use a small flat-head screwdriver to gently pry the locking collar away from its base. When replacing the connection, make sure the connector is oriented in the same way. The pin1 side is usually not indicated.

Pressure sockets for multi-wire connectors

To release this connector type, grasp it at its head and gently rock it from side to side as you pull it out. Do not pull on the wires themselves. When replacing the connection, do not try to force it. The socket only fits one way.

Pressure sockets for ribbon connectors

To release these connectors, use a small pair of needle-nose pliers to gently lift the connector away from its socket. When re placing the connection, make sure the connector is oriented in the same way. The pin1 side is usually not indicated.

Board-to-board or multi-pin sockets

To separate the boards, gently rock them from side to side as you pull them apart. If the connection is very tight, use a small flat-head screwdriver - use just enough force to st art.

Disassembly

Maintenance Precautions The following precautions are a reminder. To avoid personal injury or damage to the computer while performing a removal and/or replacement job, take the following precautions: Don't drop it. Perform your repairs and/or upgrades on a stable surface. If the computer falls, the case and other components could be damaged. 2. Don't overheat it. Note the proximity of any heating elements. Keep the computer out of direct sunlight. 3. Avo id i nt erfer enc e. Note the proximity of any high capacity transformers, electric motors, and other strong magnetic fields. These can hinder proper performance and damage components and/or data. You should also monitor the position of magnetized tools (i.e. screwdrivers). 4. Keep it dry. This is an electrical appliance. If water or any other liquid gets into it, the computer could be badly damaged. 5. Be careful with power . Avoid accidental shocks, discharges or explosions. •Before removing or servicing any part from the computer, turn the computer off and detach any power supplies. •When you want to unplug the power cord or any cable/wire, be sure to disconnect it by the plug head. Do not pull on the wire. 6. Peripherals – Turn off and detach any peripherals. 7. Beware of static discharge. ICs, such as the CPU and main support chips, are vulnerable to static electricity. Before handling any part in the computer, discharge any static electricity inside the computer. When handling a printed circuit board, do not use gloves or other materials which allow static electricity buildup. We suggest that you use an anti-static wrist strap instead. 8. Beware of corrosi on. As you perform your job, avoid touching any connector leads. Even the cleanest hands produce oils which can attract corrosive elements. 9. Keep your work environment cl ean. Tobacco smoke, dust or other air-born particulate matter is often attracted to charged surfaces, reducing performance. 10. Keep track of the components . When removing or replacing any part, be careful not to leave small parts, such as screws, loose inside the computer. 1.

Power Safety Warning Before you undertake any upgrade procedures, make sure that you have turned off the power, and disconnected all peripherals and cables (including telephone lines). It is advisable to also remove your battery in order to prevent accidentally turning the machine on.

Cleaning Do not apply cleaner directly to the computer, use a soft clean cloth. Do not use volatile (petroleum distillates) or abrasive cleaners on any part of the computer.

Remov ing the System Memory (RAM) The computer has one memory socket for 200 pin Small Outline Dual In-line Memory Modules (SO-DIMM) supporting DDR3 1333/ 1066MHz. The main memory can be expanded up to 8GB. The SO-DIMM modules supported are 1GB, 2GB and 4GB and DDRIII Modules. The total memory size is automatically detected by the POST routine once you turn on your computer.

Memory Upgrade Process 1. 2. 3. 4.

Turn off the computer, remove the battery ( page 2 - 5) and the component bay cover ( page 2 - 8 ). The RAM modules will be visible at point 1 on the main board . Gently pull the two release latches on the sides of the memory socket. The RAM module 2 will pop-up (Figure 6b ), and you can then remove it. b.
