With your BIOS the behavior is different - the laptop turns on the fan at maximum speed, and so it turns on and off, but there is no image. On my native BIOS file, the speed was always average. I also forgot to say that you can enter the test mode, when the screen shows different colors, both on the native BIOS and on yours.

Check hardware.

Help fix my bios dump. The laptop turns on and just spins the fan. There is no reaction with the other dumps, the power button just lights up.

Hi again, and thanks for your help, Peste.

I chose a different compatible chip — the Winbond 25Q256 — which I saw is similar to the 25B256DYIG.
I managed to extract the BIOS, but I'm not sure if the dump was done correctly, because the file contains a lot of zeros and doesn't look like other BIOS dumps I've seen online.

Could someone please take a look and confirm if it was read properly? I just want to make sure I have a valid copy of the original (locked) BIOS so I can proceed with unlocking it.

Thanks a lot in advance!

Just looking at this you know your backup failed.
