I think hardware have problem

On BQCN31WW.bin it works fine, but power on is 20 seconds.

 

[ThienBui]

On BQCN31WW.bin it works fine, but power on is 20 seconds.

Why doesn't it ask to clear me but asks to clear me from the old BIOS error?

 

[Qwerty220]

Clear ME please on BQCN31WW.bin

 

[ThienBui]

Clear ME please on BQCN31WW.bin

I won't help again the second time, next time please send the correct request

I wrote that on that BIOS that BQCN31WW.bin is on for 20 seconds. And my original dump has a black screen. I just sent my own dump just in case. Sorry for the misunderstanding.

I won't help again the second time, next time please send the correct request

Thanks! Everything works fine!)

Hi, i need CleanME:
LENOVO S940-14IIL LS40IC MB 18777-1 448.0HB03.0011

But I also need the other BIOS dumps since the motherboard does not start anything and I have all the correct voltages on the motherboard. You have it?
