(Hi all, Im very new to this forum, currently Im living in the UK. Apology for my English, its not my first language) I bought my new MBP last December, and after 3 month of using the computer, the computer started to display distorted colours, shapes and lines about 3 weeks ago. This happens about 5mins into usage in MAC OS (the OS is up to date). The first time I brought the computer into the Apple store to seek for help the problem could not be duplicated on site. However the Genius staff agreed to book my MBP in for further testing. And after 7 days they called me up and said they basically cannot find any problems with my MBP after all the tests they have done. So I took my MBP back and was using it in a coffee shop about 2 hours after, and the same problem came back. So I went back to the Apple store and showed it to the Genius staff again. This time the staff saw the problem and made the decision to replace the Logic Board 2.66 GHz, with a price of £325 (I still have the receipt). And they told me I will be prioritised as I am a returned customer with the same issue. Then after 5 days they called me up again said my MBP has been repaired and is ready for collection. So I went back and got the computer and the same problem happened again on the same night! But this time the computer did not respond every time the problem occurred, so by now my MBP was totally unusable. The next day I went back to the Apple shop again for the 3rd time for the same issue. And again I duplicated the problem for the Genius staff that processed me. And this time the Genius staff could not even give me an explanation of what the problem is and all he could do was book my MBP for more testing, by now I have had 12 days without my computer. After another 3 days I got a call again (on the 11th of March) but this time they were asking me for my permission to restore my MBP and therefore erase all my data, I said yes and asked to speak to the technician to find out more about the status of my MBP. When I mentioned the Logic Board of the computer was replaced already, the technician said No, it has not been replaced and you still have your original Logic Board. I asked why? He gave me the answer I am very sorry, it was a mix up. One of my colleague assumed that the Logic Board has been replaced, and therefore processed the machine as ready for collection, and I can only offer my apology to you. I was extremely angry when I heard it, but because it was only a phone call I could not take any action. So as the title says can I demand any sort of compensation from Apple? Or any other legal action? The machine is still being repaired as Im writing this post now, and it has now been 16 days since the last time I used my MBP normally. To my personal understanding, the staff told me a lie. Because even when I went back to collect my machine for the second time they did not mention any thing about the fact that no repair was carried out during my second visit to the shop. And only because I asked to speak to the technician and asked about the Logic Board repaired that have been done, that they told me the truth. And even produced me a receipt with all the price details on it for my second repair. I was lucky that my MBP is still under the 1 year warranty , but what will happen if it wasnt under warranty! Thank you for reading this, and please post any your thoughts and suggestions on what should I do. MBP 15 inch, i7 2.66GHz, 4GB RAM, 500GB Hard Drive. Mid 2010 model.
