An end user reports that their laptop shuts down when they undock it.

If a laptop shuts down when undocked and remains powered off even with a new charging cable, the internal battery is likely faulty and cannot hold a charge. Replacing the battery is the next troubleshooting step.

From the CompTIA A+ 220-1101 Official Study Guide, Objective 4.1 – Troubleshoot common hardware problems:

"If a laptop only works when docked or connected to AC power, and a replacement cable does not resolve the issue, the internal battery may need to be replaced."
