Gateway M3A laptop DC power connector problem

Hello,

I have a Gateway laptop I have had intermittent problems with the
power connection. Under warranty, we had the MD and HDD replaced
to fix it. It seemed better, but still every now and then intermittent.

Now, we can not wiggle or anything to get it to work. I have 2 power
converter cables, tried both. Also tried with battery in and out.

Do I need to preplace the dc power connection?

thanks,
Tim
