So right now, there's a principal lawsuit going on in Denmark where a customer after having won over Apple in the consumer court, is being sued by Apple for not accepting that they repaired his "new" phone with old parts... Now I'm in the same pickle. My MBP 2011 has been running without issues for all these years, then back in the beginning of 2016 I had the first issue with the horisontal stripes at boot up, eventually leading to the machine freezing. I handed it in under extended service because this is a known issue by Apple. Apparently it's the graphics card that is messed up and since it's stuck in the logic board they replace the board completely. But... I got it back after only 2 days, which I find curiously impressive considering we are talking about 5 year old spare parts. Today I put back in the 2nd ram block and fire it up. I get the 3 beeps. I do the whole hardware test thing with both blocks in the functional ram port. Nothing wrong with either of them. Then I put them both in and I get the three beeps. Mind you, this is one and a half day after they replaced the logic board. I can only conclude that they actually gave me an old board. Is there any way to find out if I indeed received a used spare part as a "repair"? Anyways, will be going back into the store either today or monday. I'm pretty disappointed.
