Lenovo Legion y740 BIOS update failed

2021-05-14, 20:51 PM

I recently updated my BIOS after being prompted by Lenovo Vantage software, said something about a critical security update. After the update, my CPU temp jumped 20C. I went to the Lenovo support page for my exact model and the BIOS available was an older version. I tried to flash back to that version, now I can't even get my bios to load. Any ideas are much appreciated.

Hello @runner0110,


Welcome to the Community Forums.


Kindly try performing a power drain by holding down the power button for 30 seconds while unplugged.

You can also try resetting the BIOS by removing the CMOS battery for a few minutes.

Hope this helps.
