Is that realistic? Not a rhetorical question: I’m genuinely curious. I ask because the last time I tried to update a single (desktop) part, it was more cost-effective to replace the whole Pc and migrate the salvageable parts since the only thing I could have held onto would have been the ram, SSD, and PSU.
I suppose with a laptop you have the monitor to also consider, and admittedly I know nothing about laptop boards, but it just seems like 6 years is replacement time anyway, at least for a daily use computer.
