Hardware Upgrades 7. To remove the front bezel, gently pull up all three tabs then pull the bezel Removing the Front Bezel To reassemble the computer, reverse the above procedure. To re-install the front bezel, insert the two bezel bottom tabs, then rotate the front bezel forward to snap the three tabs on the top of the bezel in place.
Cable Routing CAUTION: The drive data and power cables must be kept clear of the power supply and the power supply fan to avoid damage or restrict air flow. Follow these guidelines when routing the cables in the computer: 1. Route the optical drive audio cable down, alongside of the drive cage to the floor of the chassis.
Hardware Upgrades 5. Keep the top of the power supply and its fan access area Keep all cables away from the top of the power supply to prevent pinching or cutting. Also, keep cables away from the fan blade area to prevent them from interfering with the fan rotation or reducing the air flow.
DDR-SDRAM DIMMs For proper system operation, the DIMMs must be industry-standard 184-pin 2.5 volt DDR-SDRAM DIMMs with appropriate MHz-compliant CAS Latency: unbuffered PC 2100 266-MHz compliant CAS Latency 2 or 2.5 (CL =2 or CL =2.5) unbuffered PC 2700 333-MHz compliant CAS Latency 2.5 (CL = 2.5) The DDR-SDRAM DIMMs must also contain the mandatory Joint Electronic Device Engineering Council (JEDEC) Serial Presence Detect (SPD) information.
Hardware Upgrades Refer to the Computer Setup (F10) Utility Guide for information on how to determine the processor bus frequency of a specific computer. Removing or Installing DDR-SDRAM CAUTION: The memory module sockets have gold metal contacts. When upgrading the memory, it is important to use memory modules with gold metal contacts to prevent corrosion and/or oxidation resulting from having incompatible metals in contact with each other.

5. Locate the memory module sockets DIMM Socket Locations WARNING: To reduce risk of personal injury from hot surfaces, allow the internal system components to cool before touching. Removing a DDR-SDRAM DIMM 1. Press out on both latches of the DIMM socket at the same time. This releases the module and partially pushes it out of the socket.
Page 26
Hardware Upgrades Installing a DDR-SDRAM DIMM If only one memory module is used in the system, it must be installed in the same socket that held the preinstalled memory module. If you are adding a second DIMM or replacing a single smaller DIMM with two larger DIMMs, both DIMMs should be of the same capacity in order to achieve a higher performing, dual-channel mode.
3. Repeat steps 1 and 2 for any additional modules to be installed. 4. Replace the front bezel and computer access panel. 5. If you normally lock the Smart Cover Lock, use Computer Setup to relock the lock and enable the Smart Cover Sensor.
