First of all, you need to make sure your power adapter is providing enough power to both run the laptop & charge the battery. A very good way to do this is to compare your laptop voltage & ampere requirements (written on a sticker on the bottom of the laptop) with the voltage & ampere ratings of the power adapter. Voltages should be the same, or the power adapter's voltage about up to 0.5 volts more than the laptop's voltage rating. Amperage of the power adapter should be at least equal to or greater than the laptop's rating. It should never be less than the laptop's rating, or else the power adapter will be providing insufficient amperes to charge the battery. Of course, the power adapter's nominal amperage might be ok, but it degraded on usage. You can verify this by testing using a good or new power adapter.
If the battery did not charge using the new power adapter, take the battery off the laptop, & using a dry tooth brush, scrub in between the fins of the battery connector on the motherboard & on the battery it self, then put the battery back into the laptop & try again.
If this still did not resolve the problem, then the battery itself could be bad. Try it on another laptop, or try a good or new battery in your laptop.
If this did not work, there might be a possibility that the charging circuitry on the laptop's motherboard is defective & needs servicing. In order to do this, the laptop needs to be disassembled & the motherboard checked for defective/burned out components in the area near the DC jack. Any defective/burned out components found should be replaced, or you might need to replace the laptop's motherboard altogether.

My dell laptop isn't charging when plugged in. What should i do?


Dell chargers have a centre pin to allow the laptop to sense that the charger is a genuine Dell one. If the battery is not charging then:

a) Battery is faulty (old and dead)
b) Pin missing on the charger, wire broken or not original Dell device
c) Charging port on the laptop has become loose.

Hope this helps.

Dell laptop wont charge battery.


The Laptop charger or the charging point itself is bad or damaged. You'll need to try different charger to take your laptop to any nearest computer repair shop to have charging point repaired or replaced.

Its plug in but battery wont charge


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.

When i plug the charger in the first time it is working but when the charger is unplug the laptop is not working.


Hi Tim, As per my understanding you are experiencing issues with the laptop not working without a charger being plugged in.In this regards what I would suggest you do is see if the battery charges with the charger plugged in and in case the battery does get charged see if you are able to power on the laptop with just the battery connected and no charger plugged in.If you are able to get the laptop to turn on only with the charger connected and unable to power on with just the battery then it would be an issue with the battery not getting charge.So before you replace the battery please unplug all external devices from the laptop including the charger and the battery and without the charger or battery connected to the laptop please press and hold down the power button for 30 seconds after which please insert the battery into the laptop and see if you are able to turn on the laptop.This step is performed so that we could drain out unwanted static electric charges from the laptop.In case this step does not work please do consider replacing the battery since it would be an issue with the battery not getting charged. Best wishes for your effort.
