Suddenly popping, crackling sound.
I got this Macbook as a leftover from my dad. About one-and-half year has passed.
And now I found my speaker popping some weird sounds. Or you can say, it's the frequently asked crackling sound.
This happens several minutes after I turned on my Macbook. But after I left my Macbook for about 10 - 20 minutes, it doesn't happen again. The crackling sound disappeared for a time.
What do you think about this phenomenon?
Should I ignore it? Or should I go to the Apple Store?
