As I said, the laptop is new, the BIOS is already of the latest version
Just a Windows bug. I've had that happen to me before. Reboot the computer and report back.
Update: New computers don't generally ship with the latest BIOS - my Toshiba E55t-A5320 shipped with version 1.30 even though 1.50 was released 3 months before I bought it.
