Hi

Same model and same issue here.
My question is have anyone had any success replacing IT8226-192 one with IT8226-128 version and get it to work on Y540 model ?

UPDATE :

Flashed 192 verison with 128 firmware, it worked and posted without display, but HDMI outputs picture. MB have LCD power circuit issues and I m working on it

I can get picture only on HDMI output, keyboard is not functioning at all, and mb shuts down as soon as it boot to Windows.
Gonna order 192 version and try with it.

Eventually it worked without any issues. Note: This SIO doesn't need programming. I think all Lenovo ITE SIOs don't need programming. It didn't work after replacing SIO because the power ic was faulty as well. I was confused because power ic was making 3v3 and 5v alw, 3.3 was present at power button, but I was not sure if this SIO requires programming. In my country SIO cost is around 16 us$. By the way does anyone know if SIO MEC 1515 NB programmable or not. Thanks in advance

Am having the same exact issue, which is the power ic, Do you mean PU601,
