Is there a way to flash bios from USB in legion 5 15arh05h

2021-10-25, 19:47 PM

Hi,

 

I installed FSCN20WW bios update and the laptop doesn't boot any more, I even can not access to bios setup screen, just a black screen and keyboard backlights, is there a way to rollback bios? 

 

Thanks

I had the same problem after installing this Bios, just connect an external display through HDMI port, open Lenovo Vantage, enable/disable Hybrid mode and restart the computer.

Can anyone please share step by step to enter bios and reset it BLINDLY?

I don't have access to external tv, would like to reset bios to fix the problem

Example :

F2 rapidly > enter > down arrow 3 times > right arrow > enter 

 

This was a random guess, if anyone has working laptop, please check it for me 

 

Thanks

Nvm, manged to do it blindly,

Here's how you can do the same :

Shutdown your laptop

Power on then rapidly press F2

Now press down arrow 10 times to make sure you selected the option more settings and hit enter (one time was enough in my case, but just to be sure)

Now press F9 then press enter (factory reset)

Finally press F10 then enter (save and exit)

Everything should be back to normal now
