A computer's RAM (or Random Access Memory) determines how many applications the computer can have running at one time. RAM technology is evolving every day, allowing computers to run more applications more efficiently than previous generations of computers. The Compaq Presario C300 laptop computer has two RAM slots that can be upgraded to a maximum of 1024MB each, giving the computer a maximum RAM of 2048MB. Upgrading the memory on a Compaq Presario C300 requires only a few simple steps.
Select the correct RAM for the laptop. The Compaq Presario C300 laptop requires a 200-pin SODIMM DDR2 PC2-5300 or PC2-4200 memory module with a maximum size of 1GB per socket.
Unplug all of the cords from the back of the laptop and remove the battery. Flip the laptop over so that its underside is facing up.
Unscrew the screws that secure the memory module compartment cover to the back of the laptop. Lift and remove the cover.
Push open the tabs that hold the memory module in place. Carefully lift and pull the memory module out of the socket.
Push open the tabs and carefully slide the new memory module into the memory module socket. Be sure to align the notch on the memory module with the pin on the socket.
Replace the memory module compartment cover. Use the screws you removed to secure it.
