I have waited until now to report back on this post as the situation was not concluded until today. I took the laptop back to the shop and although it took a while they managed to get it on and working, and that they would have it back for repair. I said that I was unhappy with the purchase as the unit was both faulty and unfit for purpose and as such under the sale of goods act I was entitled to a replacement or my money back. The owner said he had a letter from a solicitor stating he only had to give a store credit note, but that he was prepared to source another refurbished one for me. I felt that I would accept his offer rather than go down a legal route, and bought the computer home to await his call to tell me he had another one for me, I thought at least the first one was working now so I was happy to wait, but when I got it home again it wouldn't fire up, Anyway, he contacted me last week to say he now had another laptop ready for me which was a much improved, newer, and higher speced unit than the first one but that as I had so much trouble he would do a straight exchange, keeping to the original guarantee. I picked it up today, hence the reason for todays post, and although I am not too literate with specifications it does seem a much more modern unit, so all's well that ends well and thanks to everyone who responded to my query.,
