already has a great youtube tutorial on how to disassemble the main body of your netbook and removing the motherboard. PLEASE WATCH
all parts of the tutorial or you'll probably break something - there are little release tabs in the keyboard and other things you need to look out for. (I could have included my own instructions but... he did such a great job that there's no point.)
the difference here, DON'T remove the wireless card or memory cards from the motherboard, just unplug the antennas (seen in the second photo). everything else, keyboard, motherboard, you can remove and put somewhere safe. I suggest you place the motherboard underneath the cat while you rub it frantically with a balloon - uh - on second thought, leave it on your desk.
(disclaimer: Any stickers that you remove or break might end up voiding whatever it is the sticker says it will void if you remove or break it. If you don't know how to handle sensitive components, etc! Vis a vis! Consequently! Ergo! etcetera!)
Next I will explain disassembling the screen, which is necessary to get at the antenna.
