this separate method seems unnecessary; mind just moving this to
OnPowerStatusChanged()?

  if (PowerStatus::Get()->IsOriginalSpringChargerConnected()) {
    ash::Shell::GetInstance()->system_tray_delegate()->
        ShowSpringChargerReplacementDialog();
  }

Done.

+  if (!PowerStatus::Get()->IsOriginalSpringChargerConnected())
+    return;
+
+  ash::Shell::GetInstance()->system_tray_delegate()->
+      ShowSpringChargerReplacementDialog();
