There appeared to be an agreement among vendors that nobody would acknowledge the existence of the Nvidia G84 issue because warranties had expired or were close to expiration. My in-warranty (4 years IWS turned out to be a great decision) T61p had the same issue, and I too had in fact figured out what was wrong with it while my Thinkpad was still under warranty, but Lenovo did not send me a replacement notebook (newer model) until having replaced the planar twice with the same GPU, all of which that had ever been made were known to be defective. Interestingly, the Nvidia GPU in the newer T410 I got is much slower than what was in the three years older T-series -- when it worked.
