Question about Computers & Internet
Need new battery and charger power cord
Without the Make, Model of computer It's difficult to help. But a word of advise, Beware of inexpensive aftermarket Batteries and cord/chargers. They sometimes , at best, do not work properly, a worst, can be a fire hazzard. It's cheap for a reason. Be sure to buy the EXACT power specs, Voltage, Amperage. Look to the Laptop Manufacturer for exact replacement. They may be pricey, but , in the long run a better bet.

SOURCE: Battery problem...
This issue can be caused by any of the below possibilities.
1.- Computer AC / DC cable is bad not allowing the computer battery to charge.
2.- Battery is bad.
3.- Battery charger board is bad.
1.- Computer AC / DC cable is bad not allowing the computer battery to charge
Verify that the AC and or DC cable is not bad by testing the computer only with the power plug connected and the battery out of the laptop.
2.- Battery is bad
It is possible that if the power plug is good that the computer battery is bad. Leave the computer connected to the power with the battery connected in the computer for at least one hour; if the battery does not charge, consider having the battery and/or the laptop serviced or repaired.
If the computer and/or battery is not in warranty consider just replacing the battery as it is very likely that it is just a bad battery.
3.- Battery charger board is bad
If the battery has been replaced or an alternate battery from an alternate identical laptop does not work in the computer, it is likely that the power or charger board within the laptop is bad. It is recommended that the laptop be serviced or repaired.
This will fix your problem.

SOURCE: hp power supply failiure
Ive worked on a friends G7000 series laptop, since it had the same symptoms you have with yours.
I tested it on my own(identical) working charger/PSU and still no charging.
After taking the motherboard out, i traced the fault to a short circuit FET (field effect transistor) with the PCB reference of PQ1, located right next to the connector for the DC power jack loom.(short from gate to source) The FET is made by Fairchild Semiconductors and its part number is FDS6675BZ. Being in the UK, i ordered the part from www.farnell.co.uk at a cost of 56pence. After changing this FET(which is there to control power) the laptop is working.
If you are not good with very intricate surface mount soldering, then i suggest you buy the component, take the motherboard out of the laptop(not too hard) and take them both down your local TV repair shop for them to check and change it(tell them the board reference PQ1).. shouldnt cost more than £20 or so been as they dont have to fault find.

I would say that is most likley the motherboard not the power supply and this is a pretty big job you would have to take the laptop apart if the laptop is under warrenty I would use it otherwise you would most likley be better off getting another computer unless you are very good at taking computers apart. You can go to HP website support and get repair manual and it will tell you how to take apart.

SOURCE: hp pavilion dv8000 help
I had the EXACT same issue on my HP Pavilion DV8000. After reading this thread I started disecting the machine, sure the issue was a faulty internal power plug/cable. It is TRULY a big job, but very doable without special tools. You pretty much have to take every single screw out of the thing to get to that stupid cable.
Here are a few things to know:
1) there are a lot of screws - mainly long black (L 12) and short silver (L 5x2.5). Keep track of all of them in order so you don't end up like me - with 3 leftovers. Lol. There is ONE long black screw that is a little shorted than the others (L 10). This is one I had left over. There are two VERY tiny black ones. I also have one of those left over. There is also a few smaller black ones, too. Just keep them all noted as you remove them and remember where these odd ones go!
2) There are some very flat band cables that plug in to tiny plgs. However thereis no plug on the cable. The flat end just shuves into the plugs. These are very delicate. be gentle with them.
3) When you finally get the housing for the fan loose you can now get to the entire power supply cable. Here is a note: I FIXED my problem by unplugging this cable and plugging it back in. The cable runs under the fan housing, and it seems like you have to remove that housing to get to the cable, but actually it comes out again right next to the processor and heat sink. There is a thin sheet of black sticky insulator tape over the processor and the cable at that point. You'll have to gently remove it. There is not much room there, but you CAN unplug the cable without removing the entire fan housing.
Here is what I did to test this plug and cable. After unplugging it, I shoved a tiny straightened staple (the female plug is very tiny) into the female receptacles for the prongs on the motherboard (red and black only). Then I plugged the power supply in to the power jack. With a DC meter I verified that the female end of the power cable inside the machine was getting juice, and it was.
With nothing left to test, I put it all back together (save three screws) and it is now charging the battery and running from the ad power plug. Whatever I did fixed it!
One last note: There are 4 sequenced screws that hold the heat sink tight. These are under a bit of pressure so the sink is tight. DO NOT remove these as the sink has a heat conducting "goo" that helps it disperse the processor heat. As old as these machines are now, you don't really want to disrupt that "goo" and risk the processor over heating.
I hope all of this typing helps someone.
