I don't know; I never put the laptop into sleep or hibernation, except
I have closed the lid, and I think it went into sleep, because when I
opened the lid again the screen was black for 100ms or so while the
display came back up.
Frankly, I think I rarely use the Nvidia chip. Occasionally I do some
video editing, and then watch the results, so then it might shift iunto
the Nvidia graphics, but 99% of the time I am writing or surfing the
web, and don't think it needs Nvidia for that.
I should have mentioned that I had the choice of three different Nvidia
chips, and the T2000, was in the middle.
