Re: Repaired or Replaced???
Laptops are very modular these days and it was more than likely repaired and not replaced. Here's the thing, usually when you send a laptop in for repairs they recommend you remove the HDD and battery as those aren't needed to test your system unless either one of those are causing problems. Hopefully for your sake they didn't lose your HDD or replace the system without swapping it out.
Good luck.
I won't fail you. I'm not afraid.
