If your battery will not charge, you need to run a test on some components on the laptop. The battery, the charger and the laptop itself. Once you detect the faulty conponent then you replace it with a new one.

To test the battery:
1.Power off the laptop,
2.Take out the battery,
3.Insert it in another laptop,
4.Check of it will charge,

If the battery holds a charge there, then it means the problem is not from the battery, but if it does not hold a charge, then it means the battery is defective and need to be replaced with a new one.

To test the charger:
1.Unplug the charger from the present laptop,
2.Connect it to another laptop to see if it will charge.

If it charges the laptop, then it means the charger is alright, and if it does not charge the laptop, then it means the charger is bad and need to be replaced.

To test the laptop:
1.Turn off the laptop,
2.Disconnect your present charger,
3.Remove your present battery pack,
4.Insert a well tested battery into the laptop,
5.Connect a well tested charger to the laptop.

If it powers on, then it and charges, then it means the laptop is working fine, but if it does not charge, then it means the connection port of the laptop is bad.Hope this information was helpful.

It sounds like you have a faulty power jack, and possibly a dead battery as well. You should take it to a person you may know that can order and solder a new one in or take it to your local electronics repair shop. I do repairs like this on a daily basis for my computer business.

Have you had previous problems with your laptop power supply and battery? I have this same laptop and use it very regularly. I do have problems with battery life, but never actually powering on. I suspect the battery is not accepting a charge. My suggestion is to replace the battery and see how things go.

I have an hp compaq 6720s and my charge port light blinks rapidly, it wont let me charge my battery and the computer wont turn on when the battery is full any thoughts?


Usually a rapid blinking charge light is alerting you of a battery fault. Try taking the battery out, plugging your computer in, and turning it on (with the battery out). If it boots up, then your battery is to blame, call customer service right away and see about getting a new battery.

sounds like your DC coonector came loose from the system board.it is a common problem with laptops,

Problem symptoms:

  1. Laptop randomly shuts down without any warning.
  2. Power LED and battery charge LED start flickering when you wiggle the power cord or the AC adapter tip on the back or your laptop.
  3. The battery will not get charged.
  4. When you plug AC adapter, the laptop appears to be dead and there is no LED activity at all (DC-IN jack on the system board is broken).
here is how to repair:

Battery wont work


The battery is dead and it won't charge or hold its charge (all rechargeable batteries have a finite number of charge and discharge cycles). You need to buy a new battery, or just use the laptop connected to the mains supply.
