After installing Micron NVMe driver v2.1.18.0 (which performs best on my system) on Win11 Prof. and SKHynix Controller, my shutdown time increase about 5 seconds.
In detail: Laptop shut down, LCD gets off an then it took about 5 seconds until the power off button illumination turns off.
If I switch back to generic driver, the shutdown works like a charm.
What do you think? It’s an issue by the difference of driver (Micron) and controller (SKHynix)?
