The Acer Z5600 is an all-in-one desktop computer with the monitor built into the housing. The Z5600 supports up to 8 gigabytes of DDR2 SDRAM, with dual-channel support when you install four RAM modules. Since RAM upgrades are one of the most common computer upgrades, Acer made it easy to access the memory compartment. The initial amount of memory varies depending on the configuration, but you can upgrade the RAM yourself without using any special tools.
Lay a towel down on a flat, stable surface.
Turn off the power to the Z5600 and unplug the power cable, then lay the computer face down on top of the towel.
Apply pressure at the base of the RAM cover with one hand, while lifting the top edge of the cover with the other. Set the RAM cover aside. You will see a hinge cover with vent holes under the connections, and a metal shield covering the RAM over the connections.
Grasp the cover with both hands and lift it away. You must remove the hinge cover to create enough room to slide the shield off.
Slide the metal shield covering the RAM toward the connections. You will find the RAM slots underneath.
Ground yourself by touching a metal part of the chassis.
Press the tabs on either side of the RAM stick to unlock it. You will hear a click when the tabs unlock. Lift the RAM module straight up from the slot.
Place the new RAM module into the slot by sliding it into place. The groove in the connections on the RAM module should line up with the raised area in the RAM slot. It will only fit in one way.
Press firmly on both sides of the RAM module to seat it in the slot. You will hear another click when the tabs lock into place.
Reinstall the RAM shield, hinge cover and RAM cover.
