yup. just use the palm rest for leverage and push down on the screwdriver. after you do it to one side it might not come out, but when you lift up on the other side the button will pop right off (literally).
bache, i'm glad that worked for you. like i said in the tutorial, there are many types of material you can use. I would try the foil to see how effective it is, but my washers do a darn good job already. =) and in all my tutorials i use a precision screwdriver set which minimizes scratching cause they're soo small and smooth. i'm working on the led mod tutorial now, it's rather long.
