My HP Pavilion dv7 1020us won't charge. I have the plug turned into my computer, when I plug the adapter and the cable into my laptop, it doesn't work. First it worked perfectly. But now, its very difficult to charge my laptop. Sometimes I turn the plug from my computer a few times around and plug it more in and out and after trying a whole time, it works. It takes everytime more and more time to charge my laptop. I bought my laptop in the USA, now I'm living in the Netherlands. But it worked the first months back in the Netherlands fine. Thanks.

Ok what sometimes happens is that the power cable breaks close to the Jack, or the Jack, cracks away the solder on the Motherboard... you first need to establish if you PSU, is actually putting out power, you can do this with a meter set to Volts. If it is OK, then your problem is on the MB, if NOT it is the Plug, wire to plug etc, check all this before you get a new supply, which hopefully that is what it is... If the MB cracked out... then it is a job for a service man.. or if you are handy with a soldering iron, it can be done yourself. On rare occasions it is the actual power unit Inside the PC...
