Can I carry out a BIOS update on a laptop with a connected external device?

Hi

I want to do a bios update.

Because I'm forced to use an external desktop, I'm not sure whether I can carry out a BIOS update. Read that all connected devices must be disconnected.

what do you say?

Can I still update?

You can still do it, the external screen doesn't bother you.

Oh

very well

Sure it works. Here comes the bissl "better would be ect. PP". I carry out BIOS updates on my laptops or if I have any there to iron out the "operating error" of the relatives, always without connected devices (mouse and such). This makes the device virtually "clean" since only the hardware is there that belongs to the device itself.
