Hello i find the solution. Must disable fast boot from control panel - power option - chose what the power button do - change settings that are curently unavailable - disable Turn on fast startup

M$ are a joke.
first SSD lockouts,
then wifi drivers killing usb,
now this.

reason has been discovered - M$ is using "AI" to help write software now!!!!
so is NVidia!!!

hey, does the laptop have a wifi card you can disable in the bios?
if it does - see if it fixes this issue.
