"Today I visited PC World (London, UK) because my 5-month-old laptop has developed a manufacturing fault: the hinge to the display has started to crack the plastic casing. Anyone in the know will know that this is due to the joint inside, and it means that in time the screen will separate from the keyboard. Repair was refused, because I have Gentoo Linux on my laptop, replacing the Windows Vista that was pre-installed. PC World said that installing Linux had voided my warranty and there is nothing they will do for me. I spoke to a manager, who said that he has been told to refuse any repairs if the operating system has been changed. I feel this has really gone against my statutory rights and I will do everything I can to fight it. I will review comments for your advice."
