yes...use the HxD program and cut it to size...compare with the original bios also with the HxD program and see where to start cutting..

it seems that the bios from station #2 works.. enter your bios from station #2 and the extract from the website in HxD .. look at the header of the bios.. look for it in the extract... after you find it from there down select 16MB and extract...

Hello,
I have the same issue described by @layad on that laptop: "no logo any more, boots with fan on , no display, caps lock is on all the time, no recognizing external display". I also disconnected the battery to see if any change but same: Full black screen (no light).

I suspect a BIOS corruption: Can you please explain/route me on the way to update the BIOS without screen?

Regards,

Alex

Hi
Please help me, I have the same problem. I updated the bios incorrectly, and the laptop only became a black screen, only the fan sound and the caps light! I am not an expert in updating bios. If possible, please provide detailed steps for me to apply in order to restore life to my device!

I am sorry if I violated the rules of the forum, but I am new and I am in a problem and I saw this topic, which is the same problem as mine, so I asked for help. My device, Lenovo Flex 5 15ALC05, is the same device as the original topic, and I think it is the same BIOS. I updated the BIOS, but it seems that an error occurred during the update and it became... The screen is black. I found the update on the same Lenovo website. Now I don't know how to restore the device!
I asked for the steps to update the BIOS for the black screen because I do not have sufficient knowledge. If this violates the rules of the forum, I apologize for that.

you have to give more data about the laptop (type, S/N, etc) you can find them on the label on the case and the original content of the laptop bios which is found in the bios chip.. you need an SPI programmer to extract the content of the bios chip. ..a video as an example...
