Re: Laptop will not charge battery
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.
Solutions: 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.

The problem you're having there is a motherboard issue, The computers power button is amber and it flashes that means the power inside the computer is not being distributed properly. You said that the battery is 100% charged but when you unplug the AC the computer will have no power, that means the motherboard is failing, its not identifying the battery as a source of power anymore,
You can try to use another ac adapter and check if the computer will boot up, or try to unplug and plug the memory and hard drive see if any changes will happen, If the computer turns on with another ac adapter and boots up to windows properly then try to update the bios. If the ac did not also the memory and hard drive,. You'll really need to get a new motherboard.
This isn't easily done. Have you recently replaced your power adapter for any reason. I've found that some laptop batteries won't charge if the charger is just slightly different from the original one, even if it's another Dell power adapter. If you haven't replaced the power adapter recently then it may be that your female power jack isn't properly seated or soldered into the motherboard. To reseat or resolder the jack with require you do completely dismantle your laptop. If you're not confident it doing this, then don't try it yourself. Also, resoldering the jack isn't as easy as it would seem either. Before doing any dismantling, remover your battery, turn on your computer and gently wriggle the adapter around in the female jack of the computer. Does your computer shut off on you? If so, then you definitely have power jack issues. See madhattercomputers.com
The problem could be the power jack of the laptop and/or the connections inside the laptop.
to plug the power adapter slowly and try to wiggle it. It you feel that
the power jack is wiggling, then the problem is a loose power jack that
is why it won't charge. And you need to have a tech tighten that up for
You either have a faulty ac adapter; a bad power supply in your laptop; a bad battery; or a blown LED indicator light.
1. If the connection is not loose when you plug in your ac adapter try letting the laptop charge for a while. (If you are using the correct ac adapter)
2. Try removing your battery and using the ac adapter. If this works the battery is bad.
3. Try a new ac adapter.
4. Power supply is bad
It is not a special chip that dictates if a charger can charge a certain laptop, but these two factors:
1) You need to have a power adapter/charger with the correct voltage and amps. Some common Dell laptops use 19.5V (volts) and 4.62A (amps). I have seen some Dell adapters with 3.34A (amps) as well. If you use an adapter with the wrong voltage and amperage, you could cause damage to the laptop's power supply and/or motherboard...or it just won't work at all.
2) The type of connector to the laptop. Different manufacturer's use physically different connector sizes and shapes. Some are larger and circular with a pin in the middle, while some are smaller with no pin. It depends on the laptop.
You can look at the voltage of the original charger on the brick part (the middle of the cord that looks like a brick). Make sure you get one that matches exactly.
Sound like the battery. Take the battery out and there should be a power meter on it, press it, if there are three lights that flash, the battery is shot. Not all batteries will flash if they are worn out, but they are supposed to. Try a new battery, I believe this will coorect the issue.
