Explanation
When a laptop is on a docking station, it receives continuous AC power from the dock, which masks a failing battery. The moment the laptop is undocked, it must rely solely on battery power. If the battery is degraded or dead, the laptop will power off almost immediately or within minutes. The docking station, motherboard, and display are not responsible for power delivery once unplugged from the dock - only the battery is. This is a classic symptom of a worn-out or failed laptop battery.
