I'm sure that this isn't the most appropriate place to ask this question, but I know there are some really knowledgeable around here who probably can help me.

I've had an issue with a laptop not retaining a charge. At first I tried replacing the charger and then the battery and there is no change.

Symptoms, the battery seems to charge but extremely slowly, and so slow that the computer will not stay running long even when plugged in.

The computer won't turn on without the battery in but the charger in, but occasionally the power light will flicker.

If I leave the thing to charge the battery for a couple of hours it will start up fine and be normal for a while, but eventually dies again.

My question is could the Bios be causing this problem since my charger and battery are 3rd party? I don't understand why the charger seems to be steady connected when the battery is in, but completely disconnected when its not. This puzzles me.

I'm sorry that this isn't as strictly programming as it should be.

No, shouldn't be a BIOS issue. But are you sure your charger is generating the correct output for your device? No matter how slowly the battery charges, a laptop should never stop running if it's plugged in. It should also be able to power on with the charger attached and the battery removed. –  aroth Mar 20 '12 at 3:23
    
I checked the charger and it's putting out the correct voltage. –  cody Mar 20 '12 at 3:26
    
Could it be some sort of motherboard issue? I just don't understand why it would charge some, but not how it is supposed to. –  cody Mar 20 '12 at 3:26

This definitely sounds like a third-party charger issue. What's the make and model of the laptop? –  David Schwartz Mar 20 '12 at 3:50

Sounds like your charging port on your laptop might be physically damaged. This is very likely to be true if the charger connects loosely.

I then would suspect the charger as being defective before trying to replace the battery.

Agree with @aroth that it's probably not a BIOS issue. Dell and HP BIOSes will put warning messages about incorrect or unknown battery/charger wattages but they will still boot.
