hi, my friends, I need Lenovo L-A780 R1.0 bios can anyone help?

Hello,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V.... -

Dear all, I found this forum and this is my last hope. I had a problem with BIOS update though Windows Update - it was stuck for an hour and I decided to restart. Then it bricked. The reason to update was, I had no video on my panorama display. I tried to find a BIOS on my own, but it seems that Lenovo doesn't provide a complete file, only the BIOS section. Is there any chance someone could repair it? I did a backup from the chip, attached. I also tried using another BIOS, slightly different revision. It worked and even I had a display working, but then Windows tried to update once again and it... -
Hello all,
I'm trying desperately to revive a ThinkStation P720 that I purchased from a seller who claims it suffered a "failed firmware update."
When given power, the machine turns on, spins up fans, beeps a single time, fans slow down, then a beep code is sounded repeatedly (3 high/short tones, 1 low/long tone).
Type: 30BB
Model Number: S03600

Things I have tried:

2. Attempted to boot with just a single CPU... -
Hello there.
I am working on a Lenovo Legion T5-26AMR5 desktop that currently has a corrupt BIOS and I have been unsuccessful thus far in trying to fix it myself.
History:
1. This computer came to me initially with an error message that said "BiInitializeLibrary failed 0xc0000001" or "0135 fan error". It would always be one of the two errors. It should be noted that when it produced the fan error, there was no physical problem with the fans. They were all spinning just fine.
I searched for this error online and discovered...
