I have an HP Compaq 610

Recently my laptop fell from my bed right on the power connector. I've changed the power connector with a new one. There is power to the laptop. But the now the laptop shuts down immediately after it is turned on. I can hear the CPU cooler spinning but after less than 5 seconds the laptop shuts down. What can be the issue? How can I fix it? What should I investigate? The service that fixed my power connector couldnt tell what could be the issue.


More info:

Мy laptop is not under warranty, so I took it to the best recommended service (not official, not shop repair). The needle in the power connector was broken, heavily pushed in laptop interior. They've opened the laptop and said that my DC-connector is broken. They've replaced it with new one. The point is that my laptop gets the power, and after some small amount of time (less than 5 seconds) it stops, i mean like looses the power. I've tried it with and without battery, its the same. It does not even come to boot screen, not even have powered up screen.

I'm using a 8.5 volts connector.

There is no battery light, my laptop is 3 years old. But there is light diode right above the connector. That light diode twinkles blue and then white right when the computer power collapses.

Generally, it powers up again right after each turn off, but there are cases when I had to push the power button twice.

Welcome to Super User! Caution: Never use a laptop on your bed! It will collect a lot of dust and will overheat your CPU and GPU in no time. Make sure you at least put a flat solid thing underneath it if you do want to do it. Something like an Atlas should do the job... :) –  Tom Wijsman Aug 25 '11 at 23:20
    
When the power adaptor is plugged in, does the battery charge light come on? –  Linker3000 Aug 25 '11 at 23:35

I think the problem with a non official repair service is that they don't know the exact schematics and can troubleshoot towards the actual problem. They might as well done something wrong when soldering your laptop by the looks of it, something might be getting too much power which causes a safety shutdown... –  Tom Wijsman Aug 25 '11 at 23:41
    
Does that safety shutdown works on hardware level if i may say? –  Nikola Despotoski Aug 25 '11 at 23:43

Its possible that the traces (wires) in the motherboard's printed circuit board (PCB) have been damaged or broken near the power connector, due to the fall. If this is the case your motherboard might very well be shot. You can send it to the manufacturer to have them test it; usually for a fee.
