Lenovo G580, supposedly new, for almost £300.00, from Argos on eBay. Big mistake. I went to Lenovo to register it and they said it was already over 12 months old and the warranty had expired. I contacted Argos(on eBay) who said 12 months guarantee would be provided. I can never be sure it will ever start when I try to turn it on. Very frustrating and time consuming and so undependable that I have gone back to using a Dell desktop that is at least 10 years old but more dependable than this Lenovo G580
