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...Leave a comment:
