You need to check on your notebook manual were the memory modules are located. They can be in two different places, depending on your notebook model: on its bottom or below its keyboard.
If the modules are located on the bottom of the notebook, you will need to unscrew and remove the cover that covers the memory module area. On the notebook manual you will find instructions regarding which cover should be unscrewed and removed.
If the modules are located under the keyboard, you will need to remove a screw located on the bottom of the notebook and then remove the keyboard. In our notebook the memory modules were located below the keyboard, so we will show you how to remove the keyboard.
Of course all the procedures describe from now on should be performed with the power cord detached from your notebook and also with its battery removed. Also, it should be performed with your notebook cool. If you were using your computer, please let it cool down first. This is necessary because all parts inside your notebook can be very hot.
First locate the keyboard screw on the bottom of the notebook. You should check on its manual which screw releases the keyboard.

After removing the screw, pull the keyboard forward with your hands, like we show on Figure 3. The keyboard won’t get out; this is done only to unlock it.
