How To Fix A Cord Myself When The Cable Guy Cut The Cord My Power Cord Isn't Working?

My power cord isn't working? - how to fix a cord myself when the cable guy cut the cord

I have a Gateway laptop, I hate with a passion for all consumers.
Lately, you have to manipulate the power cord so that the computer is power, and began to disturb me. Some days it's really easy to get the connection, and others, like today, will not do for a living.
I Reduced the problem to be fair, where the string, sets up the needle is in the socket, or a problem with the roller inside the computer. This is obviously something that I try to correct me, but I hope it's a cheaper way to a new strand to (I) already out of the line prices, and I have no real problem.
