I have a problem with the power lead ,where it enters the computer?

My Laptop power lead needs to be in a certain position before the taptop recieves any power, ie I have to wriggle the plug around into a suitable position. I guess that where the femail part of theplug is located has become loose on the "Board" . My question is :- is it practical for me to fix it into a permanent connection situation by using epoxy putty to hold it secure?
Thanks in anticipation
