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

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

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?
