      Was your laptop connected to the power adapter when you performed the flash? Did you follow the instructions on the Lenovo website about updating to H9ET75WW before updating to H9ET92WW?

      “You will need to flash your BIOS to H9ET75WW before updating it to H9ET84WW or H9ET92WW. Version older than H9ET75WW cannot flash to H9ET84WW or H9ET92WW directly. please flash the BIOS to H9ET75WW first.“

      1. Locate the file H9ET92WW.exe that has been downloaded.
      2. Double click the H9ET92WW.exe icon.
      3. Click install
      4. Click flash bios
      5. Press Enter to start flashing. During the process, you are advised not to turn off the computer.
      6. When the update finishes, the computer will automatically reboot for the changes to take effect.
