That depends entirely on where you are in the world. In Canada, for example, the (consumer) Lenovo service centre used to be notorious for taking weeks (three was common, I've heard as much as seven) to return machines, and for providing essentially no feedback on the machine's status until they handed you the tracking number for the return shipment. Their warranty may be fantastic, but it's utterly pointless if they won't act on it in a timely fashion. (I say “used to be”, because between this and Superfish, I've been telling everyone I know not to buy new Lenovo products for years, so admittedly, I have no recent data points.)
