Hey guys, my laptop dell 1450 really bothered me much. The problem I am facing is that :when I update the bios version to A05, the laptop 1450 turned to be frozen at some step. After I forced the laptop down, it won't start again. Now, I called the dell -tech support. And he has replaced a motherboard which bios version is A01. I want to update it to A05. How can I update it safely?
