Nvidia is still bleeding money due to the defective GPU issue, which has been problematic for them amongst multiple cards. Initially thought only to affect certain cards in the G84 and G85 series, it was later to be found more widespread. Matters were made even worse when many mobile GPUs were found to be outright defective and needed to be replaced.
This didn't make vendors happy, so Nvidia has been forced to deal with issuing refunds to them to cover their losses. Nvidia is being generous with the refund, issuing $200 per laptop, enough to cover the cost of replacing the defective part and getting it to/from the customer. Nvidia is giving this refund blankly, not accounting for laptops that might not be affected.
Nobody is quite sure how widespread the issue is, because Nvidia won't say.
