Laptop processor upgrade, no boot Tags: CPUs Laptops Celeron Boot Last response: May 31, 2012 5:22 PM in CPUs Share milmil February 5, 2012 11:59:15 AM Hello, I tried upgrading my HP 520 laptop from Celeron M 440 to dual core T2450. The BIOS detects the new CPU but laptop won't boot and there's no display. Place the Celeron back and it boots fine. What's wrong?
