Hello everyone, I need help fixing a dell latitude e6410 Core i7 Laptop. I tried removing and reinstalling the cpu on the laptop and I put everything back together. When I turn on the laptop, it wont display anything on the screen. What would be the cause of this issue. Any help would be greatly appreciated. I made sure I put in the thermal paste on cpu and installed Heatsink and fan. The fan was clean and aswell as the heat vent. I already tried other cpu's and it didn't boot up aswell. Is there any special key combination do I need to press when I power on the system. Can you think of anything else that can be useful to resolve the issue.
