Unfortunately no. I'm only booting Linux since day 0 of the laptop. This was
only required to try to flash the bios so I installed a copy of windows on an
external drive. __
Someone (the Factory) may have had Windows on it and did a quick-boot shutdown.
I do not know any other way the iface could have been left in the wrong state.
