"knitering" (funny noise from macbook top left corner)

Hi..

I dropped my Macbook a couble of days ago, nothing really happend... but i have noticed a funny noise (not very loud at all).. and would like to know if this is caused by the fall, or if it's perfectly normal..

Would some who owns a Macbook alu 13,3" be so kind and do me a tiny favour

Do you here a "funny" (like very low beeping) noise if you put your ear to the top left corner og the machine ( while opened up) ?

Please tell me so

I'm from Denmark, so sorry about any spelling

My Macbook make this noise too!

Hey, my MacBook 2Ghz make this strange noise too! Time to time, seems like a little mouse (the animal!!!) scratting a glass. It's make me think about a problem at HD engine or something like that. Very odd! And my sistem is crashing more often, frequently when I wake up the machine. Strange days. I had a bad history about 2 broked HD, so I'm alert!
