Legion Y720 bios flash

2021-07-21, 3:48 AM

Hello

 

A few months ago I had an issue with my computer and the Lenovo support told us to flash the bios we flashed the bios and it got corrupted and support is not willing to help so I'm turning to the forums to see if there is someone who knows how to do this

The fans spin up and the keyboard lights up but no video output

My model is a Y720

 

 

Thanks

Hello @Planet14356,

 

Welcome to the Community Forums.

 

I would suggest trying to perform a power drain on the machine by holding down the power button for 30 seconds while unplugged.

If this does not work it may be best to reach out to an authorized service center for assistance.

Hope this helps.
Regards,
