Question about HP Compaq nw9440 Notebook
The laptop does not recognize the charger due to a different wattage/ amperage or is not powerful enough to charge the laptop while the machine is powered. I have seen many problems with hps/compaqs and the Targus Universal Charger and recommend the HP universal charger for those models instead.

Is the Tagus adapter your original adapter?
Check the adapter wih a multimeter to see if the voltage output is or slightly greater than what is printed on the label.
The adapter may not have sufficient amps to charge the battery and run the laptop, check the current rating of the original adapter and compare it with the Targus, it should be the same voltage and current rating or higher current rating.
If the adapter is OK then the battery is worn out and needs to be replaced. Recharageable batteries have only a limited number of charge and discharge cycles, when this is reached they just don't work any more. Buy a new battery, not a 2nd hand one because of the reasons I've mentioned.

if the charger is new and you haven't been experiencing any issues with your pc prior to this, then i would contact the manufacturer and see what they say.. it could be a faulty part, has it worked before?
good luck and let me know how it goes...thanks, d

SOURCE: the laptop wont charge
I recommend grabbing an auto-voltage switching laptop charger. I'd tryUniversal Laptop Chargers, I bought mine from them a couple of monthsago and it works a treat.
Most importantly for you I think, if you buy from them and it doesn'tfit, I believe they will give you a refund. However, a quick look ontheir website suggests they have the right head for a Dell laptop, so Ithink you'll be fine.
I personally like it since it basically has the look and feel of a 120pound charger you can buy at PC World, but for a fraction of the pricesince they're online. And it charges my mobile phone too, so I'm veryhappy with it. :-)
Let us know how you get on!
