Hi guys,

I'm stuck with a bad bios on my legion Y920, it don't boot and it give me no acces to bios or something else.

Fan turn on, screen turn from black to dark grey, and nothing more...

Even after test all component or auxilliary display.

It worked slightly well and all begin after a bios reset (removed power+battery+CMOS battery)

I think bios program is damage, and i would try to reflash it with my eeprom programmer :

Could i try to flash a standard Lenovo website bios ?

Or do i need to flash m'y laptop with some of your cooked bios with my s/n number ?

Thanks a lot for all help given

Regards

Lulu

Problem was indeed somewhere else, but it was a good idea to check bios first anyway, thank you for your answers

Re: Lenovo Legion Y920 - bios request

Thank you for your time, sadly there is still no picture with this bios

Do you know at which adress DMI is stored in this bios?

you have at post #2 the bios extracted from the Lenovo website update, you won't find a better one.. either you wrote the bios chip with errors, or the laptop has another problem..
DMI 99A000 - 99BFFF
