Good afternoon, unfortunately, the same thing happened. No initialization, black screen....

Thank you. I'll check it today...

There might be a problem with boot guard (mode 4). I also couldn't clean ME ver 16.1.35.2538.

Good afternoon. Unfortunately, I couldn't find where the data lines go from the 25Q80 chip. However, I found a dump of this chip at a previous service center. However, this dump also doesn't initialize. Could someone help me check the BIOS integrity? Or could compile the dumps based on mine? Thank you in advance....

Hello, I have the same laptop. Yoga Slim 6 14IRH8. S/N: YX09V3WX, motherboard MBH83E0 I513500H UMA16G, p/n: 5B21L52211. Initially, it wouldn't turn on after a Microsoft update. The customer took it to several service centers. Now one of the flash drives on the board is empty. I created a dump of 25Q128 and 25Q64 from the official Lenovo website, but 25Q80 is empty and I don't know what should be there. Thanks in advance for any help or direction. I'm attaching two existing dumps, as well as two created ones....
