Recently, I went to a job interview. The professor asked me to get some info for him. While he was reading those info on my computer, he used his pen to guide him. His action caused marks (or scratches?) on the surface of the LCD screen of my expensive MBP 17". As I was at the interview, I could not ask him to stop doing that. (By the way, he did not offer me the job. He acted like he was going to employ me . Then, he asked me to do some research for him during the four-day-interview as potential joint project. After he got my info, he sent me a letter saying that he could not employ me since we are in different research areas and that his institute does not want to invest "too heavily" in my area. Why he asked me for the interview at the beginning?) Feeling insulted by his way of doing things, I asked him to pay for the repairing cost. He asked me why I did not raise the issue while I was in his institute. I asked him if he would pay for the repairing. It has been a few weeks but no answer from him yet. Anyway, I checked with Apple. The guy said that it would cost about $1000 for the repairing. I suppose he meant replacing the entire LCD screen. Is it possible to just replace the front surface of the screen? I guess it would be less expensive that way. Is it a good idea to try to remove those marks (perhaps ink) using alcohol? I don't quite remember but I recall reading a posting that one shouldn't use alcohol to clean the MBP's LCD screen. Mine is Matte.
