1-2 Installation Guidelines
When to Reconfigure the Computer
System configuration is the process of specifying the devices and programs that make up a computer system. When you add or remove optional equipment, the computer must be reconfigured to recognize these changes.
Windows 95 and later operating systems automatically recognize all Plug and Play devices installed. However, if the device is not a Plug and Play device or is not automatically detected after installation, follow these instructions:
In Windows 95 and later operating systems, select the Add New Hardware icon in the Control Panel and follow the instructions on the screen.
To reconfigure the computer in Windows NT version 4.0, use the software utility provided with the newly installed hardware.

Installing Additional Memory
The computer comes with synchronous dynamic random access memory (SDRAM) dual inline memory modules (DIMMs).
DIMMs
The memory sockets on the Intel 815e chipset–based system board can be populated with industry-standard DIMMs. These memory module slots are populated with at least one preinstalled memory module. To achieve the maximum memory support, you may be required to replace the preinstalled DIMM with a higher capacity DIMM.
For proper system operation, the DIMMs must be industry-standard 168-pin, unbuffered PC100– or PC133– compliant SDRAM DIMMs, depending on the model. The SDRAM DIMMs must support CAS Latency 2 or 3 (CL = 2 or CL = 3). They must also contain the mandatory Joint Electronic Device Engineering Council (JEDEC) Serial Presence Detect (SPD) information. DIMMs constructed with x4 SDRAM are not supported; the system will not start using unsupported DIMMs.
The Intel 815e chipset supports both PC100 and PC133 SDRAM DIMMs. PC133 DIMMs should be used for optimal performance. If both PC100 and PC133 SDRAM DIMMs are installed in a computer, the system memory will run at the lower 100Mhz speed. Some configurations of PC133 SDRAMs may run at 100Mhz, instead of 133Mhz.
Memory Module Installation
CAUTION: Your memory module sockets have gold metal contacts. When upgrading your 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.
CAUTION: Static electricity can damage the electronic components of the computer or optional cards. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object. Refer to Appendix E, “Electrostatic Discharge,” for more information.
CAUTION: When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the module.
Hardware Reference Guide 2-5
1.If you have locked the Smart Cover Lock, use Computer Setup to unlock the lock and disable the Smart Cover Sensor.
2.Shut down the operating system properly, then turn off the computer and any external devices, then disconnect the power cord from the power outlet.
3.Remove the access panel and locate the memory module sockets.
!WARNING: To reduce risk of personal injury from hot surfaces, allow the internal system components to cool before touching.
4.Open both latches of the memory module socket , and insert the memory module into the socket .
Begin by installing a module into the socket nearest the preinstalled module, and install the modules following the numerical order of the sockets.
A memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket. Push the module down into the socket, ensuring that the module is fully inserted and properly seated .
