In this video I disassemble a Dell 7791 laptop and replace the failed power port. The connection where you plug on the ac adapter is very loose and broken. The charge light doesn't come on when you plug it in.

The notebook needs to be taken apart halfway to access the power jack. It is a cable style port that plugs directly in the motherboard with no soldering involved.

You can also use this video to replace or upgrade the battery, hard drive, memory and more.

We perform the power jack repair services for $69 parts and labor at www.pcrepairhelp.net.
