If the Topaz takes 2 minutes to power down after disconnection from power, what does it suggest?

The situation described indicates that the Topaz device takes an unusually long time, specifically 2 minutes, to power down after being disconnected from power. This behavior suggests that the device relies on its internal battery to maintain power for a period after disconnection.

Typically, electronic devices are designed to shut down quickly when removed from power to prevent unnecessary power drainage and to signify that they are no longer operational. A prolonged shutdown time can imply that the internal battery is functioning but may not hold a charge effectively, hence drawing attention to its need for replacement or servicing.

In this context, the correct inference is that the device's extended power-down time indicates a potential problem with the internal battery, suggesting it may be weak or failing and thus needs to be replaced to ensure that the device operates normally.
