I'm now wondering whether there are different hardware versions of this card that are provided to the various vendors. Does Lenovo, for example, get a card that is changed in some way from what might released to general retail, or Dell, or SammySung, etc.
If that were true, then troubleshooting these problems, not to mention even discussing them, becomes a challenge.
