I once saw a heat map of the Macbook Pro keyboard after a while in use. Heat spiked around WEASD location. Maybe it's where the CPU is located, but the extra heat could be why those keys always seem to be the ones that go (mine were s and d, and e sometimes). But you never know..this other Macbook Pro is from Mid-2014, and keys work fine.
Or lots of people playing FPSs on their MBPs?
I think the OP meant literal heat, as generated by the CPU or other internals.
Yes, but zelos suggests that the reason these keys are problematic might not be related to heat but due to them being used more.
I did mean actual heat, but the commenter's observation about WASD also probably contributes to why those keys in particular go bad. I don't know whether the heat source underneath them or the WASD gaming use is more of a factor though.
Seems unlikely given how bad Macs still are for gaming (and how expensive they are compared to other laptops which are better equipped for it.)
I don’t think “heat map” means what you think it means.
Makes sense if you thing about it. Which user cohort needs the lowest possible latency for keyboard input? Gamers. And which keys are the most used in games? WASD. So it’s logical that these keys would be the closest to the CPU to minimize signaling latency!
