talked to my bro-in-law and told him how to reset he unit. hopefully this works.
i asked him where he bought it, he bought it from his friend who used it for about 3 months, he has the receipt, but when he called a mac center in greenhills, they told him about the scratch thing... kaya nalungkot ng husto kasi may konting gasgas sa corner yung unit nya...
i don't own any apple products so i don't know what to do with it...hehehe
