It varies depending on the model that you have, but look at the back of your laptop. Take out the battery and remove any of the panels covering your ram, hard drives etc... You will see that some of the screws are labeled with a little keyboard icon. Unscrew those, you may have to pop off a front panel as well, but if you've removed all of the screws the keyboard should come free. Make sure to look for the ribbon connecting it to the mobo as well. You will have to unplug this, and plug it back in after you've cleaned or replaced it. Good luck!
