Cleaning a standard keyboard is not a very difficult task. You can unscrew the bottom and dismantle the device and clean it anyway you want. Opening the keyboard is not a smart move but you can give it a try if you are confident of putting it back together.
However, this option is not available when you were working on your laptop. The keyboard is an integral part of the laptop and cannot be removed individually. You will have to dismantle the entire device and that is a strict No-No unless you are a licensed technician from the manufacturer. You have two options to clean the laptop keyboard.
Buy a can of compressed air or use a vacuum cleaner to air when you are holding your laptop upside down. The burst of compressed air will be enough to push even the most stubborn dirt from the bottom of the keyboard. Since you are holding it upside down, the dirt will easily slip through the cracks and will be out of your system.
Another option is to make use of a small pen knife to remove each and every key. The individual key on the keyboard of the laptop is fitted using springs and hooks. You simply have to lift the key off the hook and remove it. Fitting the key is not very difficult. Just do not use too much pressure because even the slightest crack can leave you with a vacant spot on your keyboard.
If you want to avoid the entire complication of having a dirty keyboard to be cleaned, you can go in for wireless or USB keyboard specially designed for your laptop.
