I see this is accepted - so did the battery charge or not?

The problem was using a knockoff adapter. Problem was solved when I bought a Dell adapter.

I've seen this happen when I plugged a physically and electrically compatible HP adapter (which actually had higher output, 90W vs 60W) into a Dell laptop. The system would run off the adapter, but not charge the battery. HP laptops aren't as picky, but they obviously do need a sufficiently powerful adapter. When I plugged the Dell adapter into my HP laptop, it would charge, but the system warned that the adapter was not supplying enough power to run the system at full performance and may throttle as a result: "For full performance, connect a higher capacity Smart AC Adapter."
