Hello guys. I really need your help.
I describe my situation at the moment and then how it happened.

I have a white macbook unibody model A1342.
It doesn't power on and the adapter doesn't turn green anymore.
At the moment I've found a way to power on. Pressing the SMC buttons on the keyboard and then pressing the power button on his own for a few seconds. And then press it again quickly.
The fan heater unfortunately runs fast and never cools down.

How did it happen.
My trackpad wasn't working properly, it was too heavy. So as watched in a youtube video, I had to loose the screw below after removing the battery.
So I turned off the mac, I opened the back of it and I unplugged the battery. In the moment I was unplugging the connector it appeared a little sparkle nearby on the logic board. As soon as I put everything back and I tried to power on the mac, the situation above happened.

What do you think happened? Is the logic board burned? Is the magsafe board? Obviously the second would be cheaper to replace. If it's the logic board, do you think it can be repaired, or only replaced?

Please let me know. Your help would be much appreciated.

In my opinion it's the mainboard who took the juice... Honestly I would not think on repairing it as a mainboard would cost more than the computer price.
You should put it on ebay "for spare parts", you could get maybe 100-200$ and get a new computer...
Sorry for you :/
 
Now it turned off. I need a way to turn it on again otherwise I won't be able to buy a new one from the internet.
 
I just don't understand why when I disconnected the battery connector from the logic board (with the help of a screwdriver) it came out a sparkle. (The laptop was not connected to the power supply). That's when I realised that the logic board got damaged.
 
Are you in the uk???

A guess from your username...

If so currys had the 2014 macbook airs and the retina macbook pro 13 at pretty steep discounts last week may be worth a look if you want something quick.

Screwdriver making a shortcircuit ?

Ok, so spludgers for connectors...but screwdrivers shouldn't cause shortcircuits with screws..so I should be able to use them. Is that right?

Not sure what you were doing... originally interpreted it as you used a screwdriver to disconnect the battery from the logic board (ie in place of a spudger). Are you saying you were simply unscrewing the battery retainers when it happened?

My guess would be static discharge.

I was using the screwdriver to disconnect the battery connector from the logic board when the sparkle appeared.

I was just asking in general, as I will remove the current logic board and put a new one.

The battery connector has many super small pins with... wait for it... electricity.
Using a metalic tool to remove it = #friedmotherboard

Sorry for you mate.

Nope
The nylon material appears almost shiny, but that's just from the lighting in the ifixit pictures. Not in any way metallic.
