My daughter's laptop would not power up and eventually the power jack post fell out.

I have stripped the machine down to the chassis and the last large printed circuit board, on which all the extenal ports/sockets are mounted (monitor, USB, headphones, etc). I need to get this board out to access the damaged power jack. I have removed all screws, even the hidden ones, removed the fan, heat sink and anything else but this board just will not come out. It seems to be held at the edge between the fan and the microphone/headphone jacks.
Has anyone done this before, is there a hidden clip or do I just pull and say a prayer to the god of laptops?
Any advice welcome.

Regards,
Colin.

I have completed the repair.
The battery is fully charged, the blue light is on, the fan running and there is power to the dvd, but a totally blank screen.
Any advice on what to do next.

I would check whether there is output to an external screen. That would tell you whether the problem is the onboard graphics or something to do with the inbuilt screen i.e. the screen itself or possibly the inverter.

Of course once you know, what you do about it is aother matter..................

Sorry, should have said I had tried that, no joy. This morning also checked the hard drive, that is ok also

How did you check the hard drive if you have no output to the screen?

Are you getting the post screen, but a blank screen when windows tries to load?

I borrowed one of these external hard drive boxes, put mine in it, and used a usd port on my office pc to read the drive. Everthing was there, no loss of data, or anything.

After I completed the repair initially, I assembled the laptop loosely, and powered up. I got the Windows screen and ask/said it was starting in Safe Mode. but it then crashed out completely before I could do anything and since then I get nothing on the screen.
I have since then stripped down the laptop, cleaned everthing, made sure the connections were good and re-assembled the lot firmly. When I had it on the external monitor, old style, the screen seems to "charge" but nothing appears. Power light comes, fans work, dvd table moves in and out, just nothing on the screen

It was the processor. Even though it worked initially it must have failed soon after, possibly I didn't have the heat sink up tight.
