Hello,
I updated the bios with the latest BIOS version and after restarting the PC it no longer starts, it remains with a black screen, the button LED is on.
Can anyone help me or explain the bios recovery procedure from USB?

Lenovo IdeaPad 3 15ADA05 Modello:81W1
SN:PF2C97Q3 MTM:81W100GGIX
FACTORY ID::JVHFC1
Thanks.
Regardes.
Stefan
