I have an HP-DVD 840i burner.
Yesterday, out of the nothing, when I opened the HP DVD's tray, a doughnut shape gray cushion, the size of a DVD's center came out and I don't know what it is for and don't know what to do and don't know why it happened.
Anyone with experience in opening these devices knows what this thing is for and how can I put it back?
So far, the device seems to operate correctly without this cushion, but I don't know the consequences of leaving it out.
Thanks and any help is greatly appreciated,
