updating FW when using external display (laptop lid is closed) / Lenovo X1 Carbon gen10

[ghost]

Hi, would it be possible to allow updating the FW when using external display (so laptop lid is closed), Lenovo X1 Carbon gen10?

I could theoretically try faking the lid state through:

echo open > /sys/module/button/parameters/lid_init_state

But would like to check with you first. Maybe that's generally not recommended? :-)

I could theoretically try faking the lid state through:

While that works for the OS, applying the capsule means rebooting -- and the EFI pre boot environment has it's own way of checking if the display is alive unfortunately.
