Lenovo Ideapad 700-15ISK SN and MTM program

Hello guys!

I had a problem with this laptop and support center replaced MB. After replacement everything is working fine except there is no serial number and MTM programmed in BIOS (it just says INVALID). So, LSB and similar tools can not read serial number and take me to support page. I have SN and MTM written on the back, but I want them to be programmed in the BIOS. Support center told me they don't know how to do it and to ask Lenovo. So, here I am - asking Smiley Happy


I flashed latest E5CN61WW BIOS version and I see there is WinFlash64.exe tool that came with BIOS. I'm pretty sure this tool can program serial number, but I'm not sure which option to use and how. There are many of them when I use WinFlash64 -help switch: dak, dss, dpm, dps, dvs and many, many more... Attached to this post you can see help output.


So, what is the correct command sequence to write serial number and MTM?


Thank you!
