Start taking your laptop apart piece by piece and test it after each removed component: 1. Remove the hard drive and test the laptop. 2. Remove the DVD drive and test the laptop. 3. Remove the wireless card and test the laptop. 4. Unplug the display panel from the motherboard/video card and test the laptop. etc.... Continue taking it apart until you have only three major components connected: motherboard (with video card), processor, and memory. If you still experience the same problem, most likely it's bad motherboard. By the way, before you start, try reconnecting the memory module. If you have two modules installed, try removing them one by one and test the laptop with each one separately
If your 9000 is under two years old, you should contact HP customer care and have unit serviced under warranty. HP has had allot of problems with the 6000 and 9000 units and in response has offered an additional year from date of purchase. Its worth a shut. Doesn't cost a dime. Hope this information has helped you.
The cables for these are fairly specific, but if you have a cbale that has the same plugs and fits both the transformer side and the computer side, you cna use that as a replacement. The cord itself has no polarity. Are you looking to do something else here?
