My trusty old HP pavilion dv5000 notebook (Link) that I bought in 2006 has always delivered great performance for light computing tasks until the day my power adapter started to give problems late last year. 😦
After using the power adapter for several more months by just fiddling with the cable occasionally to get a charge, the adapter stopped charging my notebook and no amount of fiddling could get it to deliver power to the notebook, thus rendering it unusable since the battery also lost it’s original charge 20 minutes into the notebook usage. A quick search on the net revealed a method of repairing the notebook’s power adapter and following the guide posted on that site, I managed to fix my adapter and it took only a couple of minutes.
(Please note that I did not have to open up the adapter box as well)
Some advise before-hand though: Do not rush to finish a delicate job like this since a sloppy repair job can deliver that fatal surge to your notebook and likely fry your motherboard in the process. Also, I have used soldering to make the coaxial cable repair job more secure.

Some pics from my own repair job just to show that it is indeed possible to repair a broken notebook power adapter with DIY and saving on the cost of a new adapter in the process. If possible, please keep the original “strain relief” for the power cable (a rubbery thing wrapped around the cable as it exits the adapter box – See top right of picture 3). Been using the repaired adapter for 2 months since the original repair date and no problems yet but I am also treating the adapter with more care nowadays and have also made my own bigger “strain relief” using a couple of plastic drinking straws taped together. 🙂
