Adding or replacing memory modules Adding memory can help improve your computer's performance. Your computer is like your physical work area. The hard drive is the filing cabinet where you store your work and the memory is the desk where you work. When your memory isn't big enough to hold all your work easily, like a desk overflowing with work, your productivity slows down. A great solution to improve performance is to expand the amount of memory you have in your computer. The computer has two memory module slots. The memory module slots are located on the bottom of the computer under the service door. The memory capacity of the computer can be upgraded by adding a memory module or replacing the existing memory module in one of the memory module slots. NOTE: Before adding or replacing a memory module, make sure the computer has the most recent BIOS version, and update the BIOS if needed. See Updating the BIOS on page 69. CAUTION: Failure to update the computer to the latest BIOS prior to installing or replacing a memory module may result in various system problems. WARNING! To reduce the risk of electric shock and damage to the equipment, unplug the power cord and remove all batteries before installing a memory module. CAUTION: Electrostatic discharge (ESD) can damage electronic components. Before beginning any procedure, ensure that you are discharged of static electricity by touching a grounded metal object. NOTE: If you are adding or replacing the memory module in your computer with a single memory module, insert the memory module into the slot closest to the system board. NOTE: To use a dual-channel configuration with a second memory module, be sure that both memory modules are identical. To add or replace a memory module: CAUTION: To prevent information loss or an unresponsive system: Shut down the computer before adding or replacing memory modules. Do not remove a memory module while the computer is on, in the Sleep state, on in Hibernation. If you are not sure whether the computer is off or in Hibernation, turn the computer on by pressing the power button. Then shut down the computer through the operating system. 1. Save your work and shut down the computer. 2. Disconnect all external devices connected to the computer. 3. Unplug the power cord from the AC outlet. 4. Turn the computer upside down on a flat surface. 5. Remove the battery from the computer (see Removing a user-replaceable battery on page 48). 6. Remove the service door from the computer. 7. If you are replacing a memory module, remove the existing memory module: a. Pull away the retention clips (1) on each side of the memory module. The memory module tilts up. Improving performance 59
