How to install memory (RAM) in your laptop.

install laptop memory
It's not difficult to install memory into your laptop. In fact it is a fairly straightforward process.

Using a screwdriver and a little care you can speed your laptop or notebook up significantly.

To install your laptop memory you will need:

  • Compatible laptop SODIMM memory module/s.
  • Anti-static wrist-strap (if available).
  • A Screwdriver suitable for your laptop's memory cover.
note: Turn the laptop off, disconnect the power and remove the battery.

Removing the memory compartment cover

The memory compartment on your laptop can be found on the underside of the machine. See your laptop's manual if you can't locate it.

Using a suitable screwdriver, undo the holding screw and gently remove the cover. Some covers have small lugs that help hold the cover in place, always check the manufacturer's instructions if in doubt.

Overview of Laptop Memory Slots

In fig 1.2 on the right are some typical laptop memory slots.

In this example there is one free memory slot. Depending on the configuration of your laptop you may have two memory modules already installed.

We have pointed out two parts of interest.

Ejectors clips.
These are used to hold the memory firmly in place.

Slot key.
This is used to align the memory module correctly.

Removing Laptop Memory (RAM)


If you don't have a free slot available then you will have to remove one (or both) of the existing modules.

To remove an existing memory module:
  • if you have an anti-static wrist strap then put it on before touching the module.
  • release the ejector clips by gently pulling them out of the sides of the module. Gently pulling both clips at the same time will release the memory module.
  • the module should pop up into more or less the position shown in fig 1.3.
  • hold the module by the edges and gently slide it out of the slot (see fig 1.4)
  • the memory module should then be placed in an anti-static bag for storage.

Installing the Laptop Memory (RAM)

Laptop memory overview
In fig 1.5 on the right is a 144-pin SODIMM RAM module. This type of module is very common in modern laptops.

You can see we have pointed out the notches.
  • Ejector clip notches (A in fig 1.5)
    • These are used to allow the ejector clips to hold the laptop memory in place.
  • Slot Key notch (B in fig 1.5)
    • This notch should be lined up with the Slot Key (see fig 1.2)
Holding the module by the corner edges (see fig 1.6), line up the Slot Key Notch (B in see fig 1.5) with the Slot Key (see fig 1.2).

Once the module is lined up with the slot key slide it into the slot ensuring the module is well seated.

When you are happy with the position of the memory module gently push it down into position (see fig 1.7).

Once the memory module is in its final position, the ejector clips should lock onto it and hold it in place.

Finishing off

Replace the laptop memory compartment cover and insert the holding screw.
Replace the battery and the power supply, turn on the laptop, the extra memory will be automatically recognised.
