When I plug the adaptor into the Hp laptop, its recognises that its plugged in, but it doesnt charge, and the laptops blue light doesn't come on. Also the adaptor beeps furiously and only stops when i turn the power off at the wall. Is this an adaptor fault or is it the laptop itself?

the problem is in your laptop...maybe it damaged too when you plugged your old adaptor. you should check your laptop for a repair...maybe it needs to replace tha spare parts that may have been damaged.
There must be a problem in the wiring of your adapter.Get it checked by a professional to avoid permanent damage to your laptop and adaptor.And if its not charging the laptop,it means that there is no proper supply from the adaptor to your laptop.
I'm assuming you are using a GENUINE Dell laptop charger designed for this model?
Check the end of the adaptor, if it is the type that has the centre pin, make sure it has not snapped off. Check the adaptor is putting out 20 volts DC by connecting a multimeter to the outer and inner parts of the DC jack.
Usually, the ac adaptor LED will flash green if there is no charge going to the laptop ("spitting back power"), however, a dead adaptor is often recognised by a lack of the lED light glowing
You can try with a universal adaptor, it will not charge the battery but at least will eliminate the charger or the charging circuit. If this also fails to power up the laptop, then the issue lies with damage to the motherboard
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
It should boot when connected directly to the power outlet through the laptop adaptor. If it is not boot, then the adaptor might not be supplying the needed power to boot it up.
If it is possible, try to isolate the issue. Charge your new battery using another laptop. Then plug it in your laptop to see if it works. If it will work, then it is the AC adaptor of your laptop that is defective. If the charged battery still won't make the laptop boot, then there is something wrong with your laptop hardware. If could be a motherboard issue of your laptop.
Try to connect the AC adaptor of your laptop and plug it to the wall outlet and let it charge for 3 hours or more. When you plug it on the wall socket, it won't show the laptop's led blinking since it was totally drained. But after 3 minutes or more, it will start to show the blinking led to indicate charging. When blinking stops led light disappears, it is fully charged and ready to use.
Remember: Do not use your laptop while it is plugged in to save your battery life. When at home, remove the battery while it is fully charged and plug the AC adaptor directly to the wall outlet. It will still work without the battery as long as it is plugged directly to the wall socket.
If the laptop will run from the adaptor, then the adaptor is probably fine. That being the case, if the charge light flashes when the adaptor is plugged in, the battery is faulty. No charge light on an otherwise working system is probably the battery charging circuit in the laptop.
very first thing u have do is if u have any other laptop try and connect the aac adaptor with that laptop and also try the battery if it is working with the other laptop that means the motherboard of the computer has gone bad u need to replace it and what also u can try is disconnect the ac adaptor and take out the battery from the laptop and the without ac adaptor and the battery press and hold down the power button for one minute and then connect the ac adaptor and put the battery back in and then try and turn on the computer and also what u can do is shut down the computer first and then just hit the power butoon once only to turn it on and then keep tapping f8 key on the keyboard and it will take u to windows advance options and select safe mode with networking and then try if it turns on to the windows screen or not......and if it doesnt turn ono then definately replace the motherboard...good luck....
If you have tested the power adaptor with a multi-meter to confirm it is OK or the other adaptor is also OK assuming that it is the correct voltage and at least the same current rating. Then the fault is most likely the power connector in the laptop.
To confirm this, power up as normal with the power adaptor connected and switched on, when the blue LED dims wriggle the power connector where it connects into the laptop and if the LED comes on or blinks, that means that you have a faulty power connector, it couls be a dry solder joint at the power connector.
It is possible that the power adaptor is shutting down (thermal overload) due to insufficient current capacity, Check the Amp rating of the laptop, it is usually on the lable on the botom of the laptop and check it against the power adaptor, the adaptor should be equal too or greater that the laptop's current rating.
To fix a faulty connector, you can dismantle the laptop and with a fine tip temperature controlled soldering iron, resolder the power connector and hopefully this will fix your prolem.
