I WILL EXPLAIN TO YOU, I WAS updating the equipment and it turned off and stopped sending video through the screen, what happens with its original bios, it sends video, I realize why the uppercase key turns on and off, the beep also sounds who gave video. With the bios that you sent me, it turns on and off, that is, it doesn't turn on completely. Do you think you can help me, I would appreciate it humbly

Hi, I need bios for Lenovo Legion T7-34IMZ5 - Type 90Q9 motherboard 5B20W27659, it has 11th gen i9 cpu, tried both the bbbbb.zip and the 8.zip and 16.zip archives, flashed with CH341A Black ( 3,3v mod ) and NeoProgrammer and verified, no differences found, but still no boot, the PC wouldn't turn on anymore after a bios update from the lenovo website...

If all bios have the same problem then you need to check the hardware

The problem occured right after the bios update, what else could it be? Also, could you please explain the difference between the first bios that u posted and the second one? I saw that the user had 90Q8 which is 10th gen, I have 11th gen, maybe that could be the issue?

Now it seems that it takes longer to post, but it still fails, after 5 or so seconds it turns off instead of turning on and immediately off, so I think the provided bios supports only 10th gen cpus, I've swapped psu, gpu, ram and even removed the ssds and replaced cmos battery.

Here are the original bios dumps after updating from windows using Lenovo's driver which resulted in a brick ( o5fjy17usa.exe )
Also, motherboard is also IZ490AE2 VER 1.3
