    The power supply we have does not have a cable that removes from the module with a plug on both ends, it is soldered inside the module and has a plug on the end of the cable that fits the computers ac adapter jack. I have the plug that was cut off and can reattach it, all i need to know is the tip or ring polarity of the plug.

    Thanks for the help, i took the laptop apart and traced the wiring to find out the polarity, now it's working fine again.

    Happy New Year

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?

    Okay, they use two different connectors on this series. Is it a barrel connector or one with three sockets?

The HP DV6500 uses a power supply with a positive tip. I have an HP supply here which has HP PartNo: 380467-005. It says replace with HP Spare: 381090-001. Input 100-24V ~ 1.5A 50-60Hz. Output: 18.5V 3.5A. Positive tip.

I have a HP dv7 laptop it does not work with the ac adapter but worked with the battery, whenever it is working with the battery and the ac adapter is connected it shuts down.

Remove the battery and plug the ac adaptor in check wethere the light on the port where you connect the ac adaptor glows or not, if no then check the wethere the ac adaptor is getting warm or not after you plug it in for few minutes if not then ac adaptor has to be replaced.
If the light on the port is glowing then it is likely that the power supply of the notebook has gone bad as it is not able to switch to ac adaptor or the port where you connect the ac adaptor to the notebook has a short circut when the acadaptor pin is connected , better try with a different ac adaptor to be sure wethere the issue is with ac adaptor or the notebook.
My best wishes

My Pavilion tx2635ea won't turn on at all! When the power cable is plugged in it lights up where the ac adaptor plugs in but when I slide the power switch to turn the laptop on nothing happens at all.


If you have multimeter then check the output voltage of the charger, if charger is not working then replace it, if charger is working then there must be a problem with mother board, try to contact some reliable repairing engineer.

Dv6500 adaptor pin connection

Color code is probably not the solution. Look in the manual for the pin out. Borrow a volt meter and power up power supply. With meter on dc volts measure voltage and notice polarity. My guess is blue is positive and bule stripe is the return for that supply, Hope this helps.

Does not start; no power indicator light

Take out the battery and then try the different ac adaptors. If you still get no lights on the laptop then the motherboard is bad and would need to be replaced. Just make sure that you know at least one of your ac adaptors are good.

If the adaptors have lights and they turn on then you know the ac adaptor your working with is good. Also make sure they are plugged into a good working outlet.

Trying to get the laptop to just work on power not battery.

Plug in your power cord from the laptop to an electrical outlet. Your battery is dead and/or needs recharged.
