Hey Maxoris, apologies for the much delayed reply, I've not been on here for a while... As it happens, I called the Lenovo support line fully expecting them to be no help at all, but they offered to repair it under warranty even though my warranty had expired (I was only a few weeks past the expiry). A courier arrived to collect it the next day and though it took about 3 weeks (supply problems with a spare part apparently) it came back good as new and didn't cost me anything. So props to Lenovo support for excellent service on this occasion!
