i have this old laptop of my girl friends im wondering the power jack got messed up there are four holes in the board two on the side and one above the other i dont know if three are ground and one power or what to find out the light tester showes me a messed up signal so any ways long story short can i temporally run the power from a different spot on the board because the top hole that i know for fact is power the trace on the board burned out so it will not resolder any help will be great

Remember that the board is a multi-layer, could have 6 or more laters of copper trace throughout it.

If the board is damaged in that area, it would be common to expect other colatteral damage to the unseen copper traces sandwiched in the board.

This often means by the time that level of damage has occured, the entire motherboard is history.

but the other spot on the board u know what i mean the place right by it with the pin that shuts the notebook down when closed shows power to it i want to un a wire just to power it up so i can take files off the hard drive to put on her new one i counted this motherboard out im doing this to take it all aprt and sell the screen keyboard ram etc... i want to try and run it off the board from another place if possible

The proper way to repair something like this is to solder the connector in place, then run a #22 (or close) wire from the power point to the socket. For additional strength, you can use RTV or epoxy to secure the new jack firmly in place.

thanks i will try this but the test light is not showing a current from the top trace or bottom to any part of the board thats why i was just thinking if there is a place close on the board to push the power through i would use a wire and re rout it

Whatever floats your boat. If the power jack is not mounted securely in the proper place, you'll quickly have yet another issue.
