still not work, maybe I should think of something else, if I got some progress I will back and report. Thanks for your help!!!

Hi, m back! And I found that bios. Here are the effects after I flash in.

please give me some time to find it🤔🤔

it's long time ago, I'll try to find it and post on

if you have other similar bios, it need not be this number's motherboard, as long as machine model is ThinkPad X13 Yoga Gen3, I'll try to flash in it. Thanks for your patience!!!🤗🤗

I can make sure the bios ic is correct. Once I flash a bios which is also 64MB and then the power light and fn light is on, but both are out of control. When you plug in or connect the battery, they will on, but whether you press the keyboard or the power key, they still on. But this bios...

emm...a bad news, it doesn't work yet😞

ok let me try it

Look at it's motherboard

It's an engineering machine and there haven't have any information on the bottom😞😞

This is an engineering machine, motherboard number is LLX-2 MB 213016-SB, it corresponds to the normal model is ThinkPad X13 Yoga Gen3 with 8GB RAM, i5-1235u(es) and 1920*1200 touch screen.
