This next step is easy. Simply remove the 4 Phillips Head Screws indicated by the red circles, then using your screwdriver, push thru the hole indicated by the red square. This will remove the bottom panel. Hint: It will be helpful to pick the netbook up before pushing thru the hole with your screwdriver.

Once you have removed the panel, you can clearly see you now have access to the hard drive bay, the RAM memory module and the WLAN module.

Replacing the back panel is simply a reversal of these steps. I hope this tutorial has been helpful.
