Hi everyone, I have this all-in-one motherboard that doesn't display an image on the screen. I already did a general check and I didn't find any obvious hardware damage. I've had several of these models that have this fault. I've already tried some of the files uploaded here without success. So please upload the original file so someone can help me.

Hello, the BIOS went out during the update. I tried all the BIOS updates. It didn't work. I downloaded the BIOS from HP according to the number. I made a backup from the same device and took an image. It doesn't see the HDD. It displays the image late. Can someone help me? Thanks. I'm attaching the BIOS that displays the image and the old backup.

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.... -
Hello,
I have an EliteBook x360 G3 where I had to replace the motherboard. Everything is working fine and there are no errors during boot. However, I have the issue that the serial number in the BIOS is incorrect. When I run the DMI tool under Windows, I get an error stating that I am not in Unlocked Mode and therefore cannot make any changes. I was able to change the Asset Tag directly in the BIOS. Now I am wondering, can I simply read the BIOS chip, change the serial number with a hex editor, and write it back, or what other options do I have? The old motherboard did not work at... -

Hi all,
I got a Lenovo Thinkbook 16P G2 ACH on the bench with a botched BIOS (somehow my client blanked it). I restored the laptop and got it up and running with original BIOS from Lenovo Support website.
My problem is now that the machine details are missing in the BIOS (Serial Number, MTM, etc.)
I tried to write the details with the Lenovo Uone Tool but had now luck. It is giving me an error: "ERROR: Locate protocol with LenovoEeprom, Status=[e]. EEPROM fail when reading or writing data."
I am now asking here for help if anyone knows how to do this in... -
