Yes, you can run it indefinitely if it's plugged in. You can even remove the battery and keep running as long as ac power is plugged in.

I can see from past posts that this issue means I need a new battery. This is my work computer and I'm supposed to be working remotely for the next two weeks, so I can't take it to my company's IT department. Do I need to keep it plugged in for the entire time I'm using it at home? If I keep it plugged in the entire time will it last me the two weeks until I'm back in the office?

Dell laptop "plugged in, not charging."
