If the laptop is still under warranty, you may be able to get the issue resolved for free. If not, yes, I have heard of this being a common issue. One of my Dell's had the same problem, but for some reason or another, the battery started charging again. It could also be a bad AC adapter or battery as well. How old is the battery? If you know someone with a Dell that uses the same AC adapter, give that a try and see if the battery will charge.
