At present I would not purchase anything, start with removing the Ram if you are confident as it is relatively straight forward on most modern notebooks, once you have removed the Ram, replace the battery and press the power button, let us know if there is any change in the behaviour such as error beeps etc.
The required tools for upgrading a notebook computer’s memory are a Phillips head screwdriver (a small one), a clean towel and a well-lit area.
First we’ll take some safety precautions.
- Unplug the notebook
- Place the notebook on the towel so it doesn’t get scratched
- Remove the notebook’s battery (this may not be possible with all notebooks)
- Hold down the notebook’s on/off power button for 10 seconds to drain any excess electricity
Most notebooks will have a process similar to what’s illustrated below.
Memory is generally considered a user-serviceable component; the access panel should be located on the bottom of the notebook. The HP EliteBook 8740w I’m using as an example has an access panel specific to RAM; take out the one screw, gently pop the cover and behold the RAM modules:
To remove a module, use your thumbs and gently push the white tabs on either side outward; the module will “pop” upward (pictured below, left).
Using your thumb and index finger, grasp the module and gently pull; be sure to pull it straight out in the direction it’s aimed (pictured below, right).
Once the module is out, be careful to avoid touching the gold metal pins at the bottom; oils from your fingertips can impede or damage the module’s performance.
Note: your notebook may have more than one RAM module installed; if you intend on replacing all of them, it’s best to remove all the modules at the same time.
Installing a memory module is the opposite. Pay special attention to the notch in between the module’s gold pins; the module will fit into the slot exactly one way. Once you have the module lined up, apply a small amount of pressure and push the module into the slot. When the module goes no further, reorient your finger and push the module sideways so the white tabs catch its edges and it snaps into place. It may require slightly more pressure than you’re use to for this to happen.
Once it’s installed, close the access panel.
