Hi. I have a Dell Inspiron 5515 with no image and the fan running at maximum speed. I uploaded the BIOS file from post #16 and the image appeared. In the hex editor, I entered my ST, selected the 5515 model, and after reprogramming the chip, everything seemed to be OK. However, now when the laptop has been running for a while, the fan spins at maximum speed again, and when I restart it, it asks me to enter the ST and select the model every time. Looking at the factory bin file, it appears to be model 5415. Unfortunately, selecting 5415 or 5515 is the same, the BIOS does not remember the serial...
