How to solve 'Battery not recognized' error.

Recently one of my friends changed his laptop battery. He has a Dell Inspiron 15R just like mine.
However he wanted a battery with a better capacity.

Now there are batteries available with different capacities like 48WHr, 60 WHr, 95 WHr and so on. His original battery was 48 WHr. And a battery of better capacity wasn't available for Inspiron 15R. So he went for a Dell Latitude laptop battery which fits into his Inspiron and is 60 WHr. The batter is original from Dell themselves, but since it not made for Inspiron, it gives this 'Battery not recognized' error sometimes. Otherwise whenever it detected it, everything was smooth and the laptop charged the battery.

If you laptop does not recognize the battery then it simply does not charge it. Though it can use it and will work till it gets fully discharged. You can then switch off your laptop and charge it in the switched off state. But this is impractical and tedious.

We broke our heads over this for a long time. Literally scoured the internet. But since the battery was giving a nice capacity which lasted 4 hours, we were reluctant on returning it. Finally found the solution. This does not make the error go away permanently and you will still get it if you don't follow the steps as mentioned below.

Solution 1: Starting without AC adapter

1) Don't plug in your AC adapter in the laptop charging port and just press the power key. Your laptop will start and give this error 90% of the times.

2) Press the power key again. Laptop will switch off.

3) Wait for 2-3 seconds and switch it on again. Miraculously you will not get the error and laptop will boot up and everything will be normal.

Solution 2: Starting with AC adapter

1) Plug in your AC adapter in the wall socket.

2) This is major step now and will take some getting used to. Plug in the DC jack in the laptop port and immediately press the power key within 3 seconds. Only then you won't get the error.

I found this solution on my own, it seems to work for us and may not work for some people. If it doesn't then try out the solutions given on these links.
