I have ordered a few t490 refurbs and never had an issue. However the one that came from this seller had a supervisor password set on the BIOS. This can only be overridden with special hardware modules (and by removing attaching the module to the motherboard). As a result, this refurbed item wasn't fully usable. The BIOS cannot be updated with security updates or fully configured by the user (me). I'm returning this one and hopefully able to get another without a supervisor password.UPDATE: The seller replaced the laptop with a new one that works perfectly
