AppleCare just repaired a messed up screen and inverter board on my white Macbook. This was done at the Apple Store, though when I received my Macbook back I noticed a messed up opening where the inverter board goes. The employee at the Apple Store said they'd cover it, along with the recent "cracking" on the white casing Apple has admitted to fixing recently. The employee said I could leave my Mac there for another 3-5 days, though I mentioned I didn't live near that particular Apple Store, nor any Apple Store. So he said to call AppleCare where they'll send me a box to ship out my Mac and AppleCare will fix the issues and mail it right back to my front door. The employee said to make sure I back up my HD cause they're known for returning Macs with erased HD's... ...I really can't back up all my contents on my 500GB HD so...can I send my Mac in without an HD?
