Laptop battery is not charging

I have a Inspiron n5110 laptop and for about a month it had a problem. It works fine (battery charges as usual) until a power drop (even for a second) occurs. When power comes back battery does not start to charge. It gives a error messeage "AC power adapter type cannot be determined"

I suspected the fault may be with the power charger/adapter and searched for new one in the store. But there I came to know compatible adapter for my 15R laptop is a 90W adapter

www.compuindia.com/.../dell-90-watt-laptop-adapter-13inches.html

And I got a 130W adapter when buying this laptop. So I thought they must have switched it by accident and it didn't bother me since it worked fine until now. But according to store, the adapter I'm using now does NOT supposed to be compatible with N5110

This is what I have now

www.compuindia.com/.../dell-130-watt-adapter.html

I have a working 90W dell adapter from my friend and i tried it to my laptop. It also gives the same error as above except my laptop identifies it as a 90w adapter and asks for a 130W adapter instead(When my adapter is plugged-in it doesn't even identify it as 130W as you can see from the image)

What might be the issue?? What should I do?

RE: Laptop battery is not charging

Hi Neji_Hyuga,

The Dell Inspiron n5110 is customized with a 90w or 130w AC adapter. If the system is configured with a discrete video card then the system is shipped out with 130w AC adapter.

I would suggest you to try flashing the BIOS on the system. Please enter your service tag # on the link below, select the operating system, and then download the BIOS from the BIOS section onto the system and install it.

Please let me know if this helps.

Hi RAVI BC,

Thanks for responding for this thread. But I already have latest BIOS in this laptop. Any other suggestions?

RE: Laptop battery is not charging

First thing to try is a new, Dell AC adapter (NOT a third party unit).

If that doesn't solve the problem, replace the DC power jack:

And if that doesn't solve it, replace the mainboard.
