Hello, while updating the BIOS on Windows, it stopped halfway and had to reset. It won't start anymore, the power button light is flashing and the fans are running constantly.
I installed the original BIOS, can you please help?

There's no way to restore old data. I've already played around with flashing different BIOS files several times.Comment

runs on this file. enters the BIOS. The extension needs to be changed to .bin.Comment

Files should be posted in a zip or rar, no need to change the file extension to txt. Flash the attached bios ,it has DMI added from a model type 81ST bios .Change your serial number with the Lenovo U1 tool - https://www.badcaps.net/forum/troubl...24#post1622424Comment

I do not know if disks were recognized before I got the laptop and fix it, but I don't see any reason why not. I can boot on USB though.

What I tested:
