I would assume that she's telling the truth. Are you looking for an excuse to yell at your girlfriend or something? Go to the manufacturer of your laptops website and go to the support page and check to see the model number and find the latest BIOS and driver updates and cross-reference that with the date that you find in the BIOS. It could have been a full-blown bios update. If it's an Intel chip it could be a management engine update. Now you do say "My laptop". I do need further clarification here. Does that mean it's yours as in you bought it for home and personal use. Was it provided by work and you didn't buy it and it was requisitioned to you by IT? Because there are many factors here that could be at play.
