I've had my MacBook Pro a year and 2 months. The past few days, I've noticed the screen flickering, and had a flashing white line across the middle a few times. Earlier today, the whole bottom half of the display went all fuzzy and coloured and nothing in that region of the display moved, while the top half still worked fine. I shut the lid, waited a few minutes and opened it again, and everything is back to normal. However, this is obviously the warning signs that my GPU too, is going to fail soon. I've finished backing up all my stuff, and I'm just literally waiting until the GPU pops. I bought my MacBook Pro from John Lewis, which offer a 2 year guarantee (first year with Apple, second with a third party UK vender Scotsys). I have 8 months left of my final year, and I'm hoping that new MacBook Pro's are released soon, so I can go in, give my case, and either demand a refund or the new MacBook Pro (hoping that it doesn't have a nVidia GPU). Last thing I want is them repairing it through Scotsys, and ending up with another failing GPU in a year's time. What is my customer rights (since I didn't buy through Apple) here, and what can I demand?
