I have a Dell XPS L511Z laptop and I recently just replaced the battery. What lead me to replacing it was before I would power on my laptop and the first screen that would pop up would be one telling me my battery was compromised and to press f1 to continue. The old battery would stay at 19% and wouldn't hold a charge when unplugged, my laptop would power down immediately.

So I had it replaced with a new battery and now the battery icon is red and it is telling me 'No battery is detected.' It doesn't have the 'battery is compromised screen' on power-up, but it is not holding a charge, it powers down if unplugged from the charger, and it stays at 0% with the 'No battery is detected' message in the bottom right. 

I have a 1yr warranty with the new battery, which I probably will have another look taken at it, but is there anything that I could do that might help? 

Thanks.
