Will the graphics module be hotplugable (or at least, able to survive surprise removal or insertion without damaging the laptop and/or the card), or will it require that the laptop be fully turned off (perhaps even requiring to unplug the battery first) before exchanging it?

(My initial guess would be that it will require at least that the laptop be powered off, or will force it to power off when removed, because from what I understood the cooling fans are in that module).
