With the bottom of the laptop facing up, locate the RAM cover.

The RAM is covered by the panel with four columns of vents.

Locate the screw (Length: 4.8 mm) holding down the panel, which is near the edge of the laptop. Unscrew it with your phillips #0 screwdriver.

Use your fingers to slide the cover away from the laptop. (It will only slide a few millimeters)

Once the panel is out of its locked position, it can be lifted out without any resistance.

To remove the RAM, use sharp end of a spudger to push the two silver tabs (see picture) away from the green RAM chip.

When both silver tabs are moved to the side, one edge of the RAM chip will pop up from its original position.
-
Use your fingers to grab the raised edge of the RAM and pull the chip away from its connection to the laptop.

-
To install the new RAM, grip the new chip exactly the same way as you gripped the old chip when you removed it.
-
Insert the gold leads of the RAM into the connection at the same angle the original chip was raised at after the tabs were released.
-
-
-
To finish the RAM installation, use your finger to push down on the center of the RAM until it clips into the silver tabs and locks into place.
-
Work backwards through the Disassembling Ram Cover Guide and then the Disassembling Battery Guide to reassemble your laptop.
