So you have removed the battery from this laptop for at least 30secs - 1minute? Not really sure about a laptop fuse? Test your DC jack for continuity - with a volt meter - outside prong and inside stem. Those will be the first few steps to finding your issue. Troubleshooting Laptop Adapter and DC Jack
Difficult to comment but if a laptop comes in for me to repair and the hinge is broken and maybe cabinet damage, I would offer to replace the broken parts and replace the DC jack, if it was faulty. It is part of the service but may not be cheap to repair!
Hinges usually become loose and very rarely break.
Did the laptop work on the power supply but not on battery?
DC Power Jacks for the most part are soldered onto the motherboard. There are some models where the DC Power Jack and the cable harness just sits in a slot on the motherboard. And there are some models where the DC Power Jack is soldered on a little circuit board that is secured by screws to hold it into place. In any case to get to the Internal DC Power Jack you have to disassemble the laptop. And if it's soldered onto the motherboard, you will spend time unsoldering the old broken Jack before you can install the new one. Get a quote from a local repair shop, then check the guys out at: http://www.generalsystemsconsulting.com They will repair it and ship it back to you via Fedex or UPS cheaper than most quotes you get including the shipping charge.
Sorry to hear that you are still having trouble. The only other thing to try is your battery on your buddies notebook. If it works there then it is the charging mechanism on your notebook and this would mean replacing the motherboard.
You First need to test your AC Adapter Cord...
You can test if you have a secondary known working one.. plug that one in to see if same issue occurs.. OR you will need to test the AC Adapter using a multimeter (available at any home improvement store for under $7).. When testing the Plug End on the AC Adapter - Hold The Negative Test Prod Of the Multimeter to the Outer Side Of the Plug Tip, and Put The Positive(red) Test Prod Inside The Plug Tip... See If You Have Power Through The AC Adapter Tip... You Might Need To Slightly Wiggle The Cord Near The Tip End To See If THere Is A Short In The Cord....
If Cord Tests Good....
You Will Need To Replace The Laptops DC Jack...
The DC Jack is the port where your AC Adapter Plugs into on the laptop..
Your Faulty DC Jack Would Need to be desoldered, the motherboard cleaned of all old flux, Re-Tin The Contact Pads and then Resolder a New DC Jack Onto The Motherboard...
Either the center pin on the dc plug or the small tension band inside the DC jack is loosing its spring, this spring action is what holds tension on the shaft of the pluug. The center pin that conducts the positive charge tends to break its solder point and therfore the chrge unless it is manipulated, the jack at this point needs to be replaced.
Basically it is just a matter of desoldering the old one, using a desoldering iron with a pump to remove the excess solder the resoldering the new one. Since you're willing to sacrifice, it can't hurt just be careful how much heat you apply because with multi layer boards you can easily screw something up by applying to much heat or solder. Good luck and please take a moment to rate as fixya.
