Well, now I can see for a few sec "LENOVO" on the screen, but blinking and than blank screen again

I tried another screen with the same result, lvds cable should be ok as well

Try this bios,flash u44 and u46, its based on your bios backup Ver 1.11 for your machine type. The previous bios i posted was based on V8.06 for a different machine type. Your DMI included.

U44 180000 - 181FFF

U46 109000 - 109030

Something very strange is ahppening here. The same story as with previous BIOS version. Logo "LENOVO", then blinking screen for a few sec and dark screen, but usb working and seems to be reading OS.
No image on HDMI, it might be a GPU I guess.

So there must be something wrong with the BIOS, because with the old one I have no image, but I can read all main powers, with BIOS from SMDFlea I dont have power on PL801 (GPU?) and on PL902 just a short time.

Or faulty GPU...

This is getting weird. I used SMDFlea's BIOS v 1.11 again, flashed EC as well, with this images I can read all main powers but see error code "15" on postcard with no image on screen, of course.

Another EC for you to try .

Re: Lenovo Ideapad S400 touch LA-8952P BIOS Please

So it's done. Finally I changed that GPU and it seems to work perfectly now.

Many thanks to SMDFlea!
