I have already ordered a replacement dc jack for my brothers gateway, but once i desoldered the existing jack, i found that one of the prong holes is very charred to the extent that i can't really see any metal connection for the new jack to make. I thought i had read somewhere a while ago about patching the motherboard in this instance(because on occasion the flexing back and forth of the power chord can cause the prong to burn the mobo when not charging properly), but now that i need to know, everytime i look online all i find is software patches and what not. Anywhoo, if anyone knows weather this does/doesn't need to be patched and if it does, how exactly do i patch it i would really appreciate their response..
