I'm seeing red I am so furious over this. This machine has hinge cracks on both hinges. I have not mistreated this machine (It does not leave the desktop and I shut the screen using two hands and gently). I am sick to death of returning computers for bad memory and broken parts. Are the cracked hinges a cosmetic defect? Are the hinges actually metal with a plastic covering? Will I experience a loss of function? Wanna kill these ads? We can help!
