I have a Toshiba A75-S213 laptop, and am having a problem with the power cord connection. When I plug in the AC power cord it does not go to AC power right away, and most times I have to wiggle the connection at the laptop for it to catch. This is causing the battery to be used more, and I am concerned that if I don't figure out the problem soon, eventually the battery might be completely drained. Does anyone have a fix for this? Thanks.
