- Create a bootable USB drive with the downloaded file (instructions are usually provided with the BIOS update).
- Plug in the USB and restart the laptop while holding down the Fn + R keys or the Novo button to initiate recovery.
If recovery isn’t working, it may require professional assistance to reflash the BIOS.
