Hi can you help please or sugest something.thanks

the bios from post #7 is the one from the Lenovo website..it should work..either you wrote the bios with errors..or the laptop has another problem..check the voltages on the bios chip and on the coils..

[jogas]

id did check all voltages.all ok pressit on all coils.only oem bios make spin fan once and gpu and ssd get warm after min or so..other bin files not doing this.try few an nothing. plain black screen.

Hello, I wanted the same BIOS file model without graphics. Thank you for your guidance

If its DIS to UMA look for a hardware solution, the bios can`t be edited. There is no seperate UMA bios.
