I am experiencing slow startup times on my XPS 8950 machine. Upon investigating Task Manager>Startup, I found that the last BIOS Time is 26.5 seconds, which is much slower than the less than 5 seconds I have observed on previous machines. Although I have installed the most recent BIOS update.
XPS 8950, slow startup help to fix it
