Charger plugged in but battery isn't charging. laptop only comes on when plugged.

if the battery is above 90 percent this is normal , if it isn`t then you charger - or nb plug malfunctioned and is not recognized as genuine hp charger and will only power on to prevent damage to battery. TRY NEW CHARGER

This is a common problem. It may be that the charger is dammaged. these Dell chargers have a micro thin communication cable in them that tell the charger to charge the battery. this micro thin cable can often break. Its use it to prevent the laptop battery from over charging, but if it breaks or becomed broken inside tha charger cable, then the laptop simply won't get the charge signal and the battery won't charge. If this is the case, then you will need to replace the charger with another Dell charger compatible with your laptop

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 one of three things:

1. Battery itself no longer functions
2. Laptop Charger has inadequate amperage
3. The motherboard is defective (most likely).

If you have another battery, or a friend with the same battery, you can try that first (and someone else's laptop charger).

Take the battery out. Unplug the charger from the computer. Press the On button for 30 seconds. Then plug the charger in. If it works, then put the battery back in and you're in business again.If it doesn't work, the most likely cause is the laptop charger. Use a new one to confirm:

why did you change the batteries, did you verify that it wasn't the charger in the first place, sometime the charger will appear to charge but actually isn't. put a meter on one battery then plug in charger if voltage goes up charger is good if not look for loose connections and or bad charger.

charge your battery on another phone and then place your battery in your phone and switch on your phone and connect the charger to it if still it isn't charging then check your charger and if the charger is ok then you need to repair your phone manually or by taking it to authorized dealer

You can try to try a different charger,if it doest charge the battery,try to use your charger to a compatible phone. If it charge the second phone,that means that your charger is fine,it might be a battery issue. For sure,either the battery or the charger needs replacing.

please explain further.. do you mean your laptops power adapter cord?
thanks for using fixya

It generally is a cheap repair, however it may be the battery. Quite frequently when that happens the battery is mainly the problem. The DC jack does not get affected unless it is disturbed.

check them with a multimeter and see if they are showing at least 12 volts
