Hi there, please could someone have a look at my bios bin file. I believe the bios to be corrupted as my Lenovo yoga c740-14iml will not turn on at all with the battery charged and all other possible issues checked. Board is FYG41 NM-C431 REV 1.0. Just a slow pulse of power led, pressing the power button does Nothing. If the corrupt file cannot be used in anyway, could someone send me a clean original bios bin file adapted to use. This would be much appreciated

The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

Already done this, I've unsoldered then soldered it on a CH341a to read the data, i saved the original bin file, only once though. I then erased the chip thinking I had the replacement file, I know a noob thing to do. Also I didn't realise the file should be a few mb. This was before I came here, I was hoping originally to write the update file from the Lenovo website to the chip via the Ch341a, thinking just write a bin file but none contained in the download. The file I sent earlier is the dump from the chip
