Hi,

I recently upgraded the CPU on my 6 year old laptop.

The laptop came with i7-3610QM and I decided to swap the original CPU with a second hand i7-3520M.
Both CPUs are listed in the laptop specs that can be found in the below link

After the swap when I tried to start the laptop, the laptop shut down almost immediately with only some indicator leds blinking for miliseconds while having black screen.
As I suspected that something could be wrong with the new CPU, I removed it and installed back the original one.
The laptop had exactly the same behavior.

What could cause this strange behavior? Is this something that I could detect and fix?
During the swap everything went smoothly and it seems that it is not something with the new CPU.

Thanks in advance for your help!

Regards,
Akis
