Thanks for the details!

An optimus configuration means that display and basic acceleration is
provided by an integrated Intel graphics, and the NVIDIA GPU can be
switched on/off dynamically to provide more power when needed.

According to your laptop reference, this seems to be the kind of
configuration you have. It is relevant because this issue seems to
happen when the NVIDIA GPU is switched off during boot.
