[DigitalDrifta]

Hi,

Wonder if someone could assist with my issue. I set my bios password a couple years ago and I can't remember it. I tried going through the guides but lost in the Hex editing of DMI Would really appreciate if someone could assist in clearing the password for me.

Lenovo ThinkBook 13s G2 ITL
Serial: PW03Z1CD
MTM: 20V900AXUK
Bios Version: F9CN51WW

Regards,
Steve

Hi, I tested the above but SctWinFlash64 didn't like it. I opened the bin you posted with a hex editor and can't find my serial in it? Was it generated from my dump and which tool did you use? Thanks!

hardware1 Looks like you've done this laptop model before, any advice?

It is 22mb. It should be 8mb or 16mb or 32mb ....
post the original bios of the laptop even if it is corrupted

Thanks for the info danito . I dumped it with SctWinFlash64 from within Windows. Should I purchase a CH341A or T48 or could it be dumped via any other software?

you have to read full content of bios chipset with a programmer. You only have bios region extracted with some bios backup tool.

Thanks, I've ordered a CH431A and will post when I have a proper bios dump. Apologies, I thought I could use the Lenovo Bios tool to dump it
