Dust in the PowerBook

[thumper]

Ive had my powerbook for about 2 years now and was wondering
how to clean the insides.

i think there must be a lot of dust in my powerbook cuz ive noticed dust right above the F2 key by the little vent and it looks like the fan blows
it up and on to my screen.

ive seen the inside of other computers and sometimes the fan is caked
with dust and crap...

any ideas???

Some may advise against this, but I've used a can of compressed air with great results.
