Laptop black screen

Hi, recently I was given an old Fujitsu Siemens Amilo M1450 Laptop. I disassembled it because it had two broken USB ports. I fixed the USB ports and assembled it back. But when I turned it on after assembling it the screen was black and keyboard wasn't responding, I was trying to disable Caps Lock and Num Lock but it wasn't working.

I checked cables and also checked if any component was put wrong. I also tried to boot it with one ram per slot(because it is dual channel) or with no ram. Note that when I took of the CPU I accidentally wraped a pin, It was just leaning against the other pin and I put it back in it's normal position. What it may be the problem?

It is hard telling what is going on. Taking apart a laptop and re assembling it tends to be way harder than doing the same on a desktop system. You could have zapped it with ESD (cpu, motherboard, any IC chip), but chances are you just didn't put it back together quite right. I would take it back apart and slowly put it together again making sure that all cables and connections are properly seated (those flat ribbon cables can be a pain sometimes). As long as the pin on the cpu didn't break and you straightened it that shouldn't be the issue.
