Default AC Adapter or Battery Problem?

My grandparents have a Dell Vostro 1000 laptop that has run fine for the most part until today when they told me a message about the AC Adapter came up before the desktop. It read as followed:

"The AC Adapter type cannot be determined. This will prevent optimal system performance. Please check AC Adapter, connect properly, remove AC adapter, and plug-in it again."

At the desktop however the computer says the battery is fine and so does the Device Manager. However, when I was in the Device Manager I noticed that under Network Adapters there was a yellow exclamation mark for Microsoft Tun Miniport Adapter #2. They still have connection to the Internet with the other adapter, but thought it was strange to see that.

Can anyone help me with what's going on?

Sounds like the adapter. If you unplug the laptop and it runs off the batery, does it have a normal life span before the battery runs out?
