I would think probably not. I know that you get a 1 year warranty on computer but to have it repaired after 2.5 years I cannot see that happening. I would think you would need to have taken out insurance in case of breakdown but you would have to have paid for that.
I would say no they will not repair it unless you pay them but I am sure others may give you different advice. Fit for purpose is usually one that comes up.
It will be interesting to hear different views. I am sure the Forum Editor would be able to give you the proper answer to your question.
