I have a Lenovo think pad and a few weeks back it packed up and diagnosed as a motherboard failure which was somewhat disapponting being just over 2 years old and out of warranty.
I thought it worth writing a letter to them expressing my displeasure etc and to my amazement they agreed to the return of the laptop, repaired it F.O.C. and it works perfectly again.
I doubt that not too many manufacturers would be that sympathetic so full marks to Lenovo and I hope u get many years enjoyment from yours.
