Default Yoga 370 LA-E291P does not enter the bios

Hello there ,

I comment on my problem.

I have a lenovo yoga 370 I bought it on ebay, but it does not allow me to enter the bios, it remains in an infinite loop with the word entering setup and the points and does not advance from there.

I can run w10 without any problem even linux with secure boot activated.

but I want to enter the bios to make some changes ..

the board is CIZS1 LA-E291P
rev: 1a
2016-12-14

Thanks in advance
