They opened it up without backing up my data! And there was dirt all over my screen when I opened it in the store. The back up drive I bought in their store was NEVER opened. They will try everything they can to complicate anything going on! To top it off they opened the computer and were trying to start the repair. I'm not sure what her business card was going to do for the situation.ĭO NOT TAKE YOU REPAIRS TO THE APPLE STORE. The manager tried to give me her business card and when I did not want it got irritated and annoyed. They again refused to give me pictures about what they were talking about.
They said somewhere else may be able to just replace the Optic Driver without sending it out,etc. I went to pick it up because the whole thing seems fishy to me.
They know this is a work computer that I use daily at work. They had my computer for 4 days and now wanted to send it somewhere to an "Apple repair center". They said legally they could not email me pictures of what is going on in my computer. I asked them to email the pictures of this as I was at work. Now the ONLY thing not working in my computer is the eject on the CD/DVD player. And anything they deemed not working would need to be replaced. So they would need to send it out and have ALL OF THE COMPONENTS of my computer tested. They called me yesterday to say they found RUST inside my computer (which has never been wet). They said this would add 1 day to the repair.
I bought a back up drive so they could back it up because they could not promise data would not be lost. They said it would take 1 wk to replace the optic driver and repair switch. I was their for 1 hr and the tech had my computer out back for 45 minutes before they let me go. I dropped mine off for repair for this reason and the back battery eject lever is broken. Whatever you do don't bother taking it to an Apple Store for help. This same thing is happening to my Macbook.
