Lenovo no spares

<p>I sold a Lenovo to one of my clients after 3 months it stopped working. It is a waranty claim so i took it in to Partserve. Now 2 weeks without a pc and they are awaiting spares. This is a new pc, should there not be stock on its spares. I sold over 20 of these units to my clients. What happens if they break they do not have any support or spares.</p>
