Hi, can some clean my Lenovo Yoga 730-15IKB laptop dump. As of now "NO DISPLAY" but all the voltages seem to be fine & the fan spins too. The startup even seems to be normal. I have uploaded the Original BIOS Dump, kindly clean. The machine Model Name 81CU & Serial # is MP1PEERG.. Thanks in advance

Thank you so very much, will try it tomorrow first thing in the morning... Do you know there is another 8MB Bios on the motherboard., what is this for???

Re: Lenovo Yoga 730-15IKB dump

There is no second 8MB bios chip, maybe you are talking about the EC chip, but it's not 8MB.

Re: Lenovo Yoga 730-15IKB dump

Pls. Check this photo, it clearly show another BIOS chip, it's surely not the EC chip. Now for the BIOS I re-programmed, but still NO DISPLAY, now I see that the Amp meter is stuck at 0.95 amps & in the start goes up & down & then stays at 0.95 amp., where as in the older BIOS it was just stuck at 0.45 amp. I think your BIOS update needs a little more touch up, all might work again.. Thanks in advance.

Look at the traces ,see where they`re going,straight to the TPS65988 chip. USB-C firmware .Schematic https://www.badcaps.net/forum/showthread.php?p=1069721

The bios posted by Vesko is a virgin one.

A little more touch up? Give me a break will you It's a virgin update straight from the Lenovo web update page, with your DMI and Windows key added to it, so I can't make any better "touch up" upgrade on top of the factory build.
SMDFlea is right, this is a USB-C firmware chip, and besides I think it's not 8MB, I can't see the marking but usually USB-C firmware is not so big, I don't know why you think it's 8MB, see what are the markings on the chip, and you'll find exactly what is the capacity.

Yes it is, thank you - virgin bios with clean ME firmware. The problem if the board doesn't turn on, can not be bios related.

Ok, the marking on the Winbond Chip is 25Q80DVSIG.. Good is that I got the display with your 100% working BIOS. Actually the PCIe SSD Card is shorted this is why I guess the BIOS dump got corrupted. Removed it from the slot & all worked fine. But now again it got dead as soon as I put in this card again, but tomorrow will figure out what's the problem. Thanks for all the help.

Yes, just as I guessed.
80 in the marking of the chip does not mean 8.0MB
