These sections contain important ESD precautions along with preinstallation and post-installation instructions. ESD precautions Electrostatic discharge (ESD) can damage your processor, disk drives, expansion boards, and other components. Always observe the following precautions before you install a computer component: 1Do not remove a component from its protective packaging until you are ready to install it. 2Wear a wrist grounding strap and attach it to a metal part of the computer before handling components. If a wrist strap is not available, maintain contact with the computer throughout any procedure requiring ESD protection. Preinstallation instructions Always observe the following before you install any component: 1Turn off your computer and all the peripherals connected to it before opening it. Then unplug all cables from the power outlets. 2Open your computer according to the instructions on page 23. 3Follow the ESD precautions described above before handling a computer component. 4Remove any expansion boards or peripherals that block access to the DIMM sockets or component connectors. 5See the following sections for specific instructions on the component you wish to install. Warning! Not turning off the computer properly before you start installing the components may cause serious damage. Do not attempt the procedures described in the following sections unless you are a qualified service technician. Post-installation instructions Observe the following after installing a computer component: 1See to it that the components are installed according to the step-by-step instructions in their respective sections. 2Replace any expansion boards or peripherals that you removed earlier. 3Replace the side panel. 4Replace the bezel door. 5Connect the necessary cables. 6Turn on your computer. Opening your computer Caution: Before you proceed, make sure that you have turned off your computer and all peripherals connected to it. Read the Preinstallation instructions on page 22. You need to open your computer before you can install upgrade components. The side panel is removable to allow access to the computer’s internal components. Refer to the following section for instructions. Removing and installing a hard drive The computer supports up to two easy-swap hard disk drives. Each hard disk is mounted in a carrier that holds a standard 3.5-inch Serial ATA hard drive and connects to a SATA interface on the disk cage backplane. Easy-swap technology shortens system downtime for changing the hard disk or performing an upgrade. Note: Do not attach or detach the hard drive while the system is on. It may cause damage to the device or lose data. To remove a hard drive: 1Observe the ESD precautions described on page 22. 2Open the drive bay door. 3Press the HDD carrier latch, then pull the lever and slide the carrier from the chassis. 4Place the HDD carrier on a clean surface. Adding a hard disk drive 1Open the drive bay door. 2Press the hard disk carrier latch and pull the lever. 3Slide the hard disk carrier from the chassis. 4Insert the right side of the new drive into the carrier, aligning the pins with the hard disk mounting holes. 5Gently open the tab at the front of the carrier; insert the pin into the front mounting hole. Bend the rear part of the carrier open; insert the pin into the rear mounting hole. 6With the lever still extended, slide the carrier all the way into the drive bay, and close the cover. Upgrading the system memory This section explains the procedures for removing and installing a memory module. System memory interface The four 240-pin sockets on the mainboard support Double Data Rate 3 (DDR3) Synchronous Dynamic Random Access Memory (SDRAM)-type DIMMs. You may install 1 GB or 2 GB DIMMs for a maximum memory capacity of 8 GB. System memory configuration guidelines •To ensure data integrity, use only Acer-approved modules in 1 GB or 2 GB capacities. •Use identical modules — same specification for size, speed, and organization. •In minimum configuration, the FDB should be installed in DIMM 2 slot. To remove a memory module: 1Observe the ESD precautions described on page 22. 2Lay the system on its side (components showing). 3Press the holding clips on both sides of the DIMM slot outward to release the DIMM (1). 4Gently pull the DIMM upward to remove it from the DIMM slot (2). 5If you intend to install a new memory module, proceed to the next section for related procedure, then observe the post-installation instructions described on page...
