I changed the cpu of my laptop and since then the screen has not come on.
The fan comes on when I press the on button but nothing happens even when I connect a second monitor.
Depending on the device, the graphics card may be loose / the cable may no longer be inserted correctly. Or it put it completely.
What device are we dealing with here?
The laptop is an hp 630 in which I have built an intel core i5 and I have improved the RAM
Which i5? There are different generations.
I don't know exactly which one I took out of my old broken laptop
Then what kind of device was that that would help me.
The old laptop was a thinkpad t510i
Since the processors have nothing in common except for the socket, the chipset with the processor will not be able to. In the worst case, you have transported the entire device into the eternal hunting grounds. In addition, the processor that was installed is a generation younger, so you would have done a downgrade.
