Thankyou for your reply!

I had previously tried to desolder a chip and replace it with a preprogrammed one however to no avail. It was a 11th Gen Dell Latittude, However up-on installing the new chip the machine wouldn't boot. I do have 3 more laptops too attempt however moving forward I'm going to try and modify the current bin file as opposed to replacing the whole chip. Could I ask, When replacing the bios chip with a pre-programmed one, Should I have replaced the EC chip? I'm truing to workout where I went wrong. I did resolve the original chip back however the laptop still wouldn't...
