When i decided to buy a laptop 2 months ago i thought that i would get a mac. I needed one for college and apple computers are reliable and are cool looking. I didn't need all the bells and whistles but i wanted a good computer so i got a refurbished black macbook. Its the 2.4ghz with 250g of memory. It was like 1200 so i thought id pick it up. It thought it was a great idea but... From the moment i opened it i know there would be problems. On the screen was a long straight smudge that was caused but the plastic piece between the track pad and the keyboard. It was slightly raised up and touching the screen. I wiped the smudge away hoping it wouldn't return but a week later it was back. I brought it to a registered repair center to get it fixed because along with the screen there was a clicking noise on the track pad button. I picked it up the next day but the problems just got worse. The guy replaced the piece that cause the mark but only made it worse. The new piece was even worse so i called apple. They sent me a box and it came back in 3 days. They replaced the keyboard, track pad, and the plastic piece. The new track pad didn't work though. I sent it in again last week and just got it back today. The hing on the screen is getting progressively louder squeaking and cracking. The light on the isight camera wont go off but the track pad works this time. What is with this laptop? Is it a lemon? Should i cut my losses and sell it and buy a new one? If the screen gets any louder i am going to have to send it in again and this would be the 4th repair. At what point do i throw it against a wall?
