兄弟这是我测试过的，之前主板问题是不认WiFi，在刷一下这个BIOS

你的这个我这个机子也不触发，现在的机子真是奇奇怪怪的

I'm fighting with one right now... these are my discoveris that it might help

first, there are two types of this machine, vPro with 256M bios chip and non-vPro with 128M Bios

Lenovo's update has two files 37MB each, R15ET ** W and R15ET** P , I don't know which is which or the difference but according to my previously working backup vPro is W

secondly, This mchine will not trigger with a bios that contains a lower version of intel management engine if it was working on a higher version before !

for example, if you take a working bios backup of your working machine and it has ME 14.1.53.1649 then update your system to the latest released ME 14.1.74.2355, your old backup won't trigger anymore!

it will trigger only if you inject the new ME in your backup, that's what I did and the problems start (m.2 doesn't work anymore) Although the new ME was taken from lenovo's update !

even the ME update contains two files Consumer_LP & Corporate_LP and according to my backup my vPro uses Corp_LP

I made a dump from scrach based on the latest lenovo update Bios v1.42 & EC v1.12 + ME 14.1.74.2355_Corp_LP, flashed that + EC flash but still no m.2 note that if you remove the drive an error message appears that m.2 is not detected..

Injected 14.1.74.2355 or 14.1.70.2228 in the original working backup, still no m.2

I didn't figure it out yet, why it won't start with the original backup and original ME, and why an official bios with updated ME won't detect m.2 ??

I'll share all the files it might help.. (all vPro 256M Bios version)

Original backup of the machine + original ME 14.1.53.1649 tested ok m.2 ok (wont trigger anymore after ME update)

The first one is unusable. It can be turned on but the boot is slow and the hard disk is not recognized. Attached is the BIOS that Xiao Hu sent to everyone that was tested OK

this one is non-vPro for 128M bios and ME version is 14.0.33.1125 clean
I didn't download OP's two files they are non-vPro too (from the size of the files) this should be noted..
