Dell laptop not recognizing battery; charging disabled.

My Dell Inspiron N7110 went off warranty Dec 2012. While it was on warranty, in July 2012, I had a problem with the battery charging being disabled and the laptop not 'recognizing' the battery. Dell tech services got the laptop to recognize the battery. I thought I wrote down the steps. However, now it is happening again and I can't seem to get it to recognize the battery. Since the laptop is a couple years old, perhaps I need to buy a new battery. It runs Win 7 Home.

My question is: if I put a new battery in at this point, will the laptop recognize it? Do I need to get the recognition problem resolved before I buy a battery? The battery is still at 90%, losing 1% per day, but I don't dare take it off house current. I don't have another laptop to test the battery on.

 

I simply turned nac4ev's code entry to a straight forward hyperlink. I took a look at the page and there may be some useful information for you there.
