Hey sir,

Lenovo y540
Board: NM-C221 Rev 2.0

I have dead dedicated gpu on this laptop. Can you somehow switch it on bios to integrated intel gpu? Or is there any way how to solve it on board like for example remove some components?
Thanks.

Thien , this file should be posted on the first post , and mentioning this is the CORRECT flashing FILE , flashing via keyboard line if you read the file first it will give you a 56kb file - so there is no point in telling people to flash the 128~EC files removed from main bios ... its making peple waste of time , and many of us allready told you that , but you keep misleading people to fake and bad info !
