Not too sure depends on their policy. I had an LG telly from currys, went back for repair 3 times, until I said that I am not interested in having it back, so I got a Samsung instead and haven't had a problem since.

Go into the store and kick up a stink, you'll get what you want if you try hard enough!

Make sure you get refunded or credited for a replacement in full for the original cost of the laptop. Currys tried fobbing me off with another of the same size and make, which was a couple of hundred pounds cheaper than the one I bought!
