You need to have the power jack resoldered to the board, not for the faint of heart. I do this kind of work on a daily basis. Basically have to take the laptop completely apart, and may have to order a new power jack if it is damaged. Tedious work that requires a steady hand and in some places can be quite expensive. If your laptop is over 3 yrs. old, not worth it. But odds are your information is intact, so if fixing the power jack is too costly, take it to a repair shop and have them backup your data for you. If you want me to fix it, it's about $150 and I will only charge you shipping for your laptop and give you the jack at cost, which are normally around 10 to 20 bucks + shipping. Email me at firstname.lastname@example.org. I am a licensed computer technican in the Naples, FL area and have been working on computers for 18 years. Take care.

Remove the keypad and check for fault in the pads. clean them well and checck the leads to the pads.
If there is not result or you see visible damage then it is possibble that a good service will result only by changing the keyboard.
Doing a sofft job will bring the fault back once again.
One of the great features of USB devices is they can get power from the USB port. Plug in a thumb drive and it just works. The power for operating the thumb drive comes from the USB port. This works for small devices like a thumb drive but not something big like a scanner. The scanner need its own power supply.
There could be several explinations for what you are seeing. Could be you are plugging in a device which is sucking too much power and the laptop is shutting it down. I would test the port with something small like a thumb drive and see if it works. If the thumb drive works but the other device does not a couple of things could be going on. Maybe the device just need power - is there a way to plug in a power supply? Or maybe the device is broken and shorted out. Does the device work on another computer?
If something like a thumb drive does not work then it is a problem with the motherboard. Could be the USB ports are bad. It happens and there usually is no easy fix short or replacing the motherboard ($$$). Occasionally there is a BIOS setting for the USB ports. A bit of a long shot but worth a look.
A possible work around would be to get a power USB hub. A hub plugs into a USB port and provides 4 or 7 USB ports. Good ones come with a power supply. When the hub is plugged into the power supply it does not draw power from the computer. Might solve your problem.
