Electronic device are still alive even when they are off?

Click For Summary

Discussion Overview

The discussion revolves around whether electronic devices remain "alive" or operational in some capacity when they are turned off. It explores various aspects of this phenomenon, including the functionality of standby modes, power consumption, and the implications of different device designs.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • Some participants suggest that it depends on the device, noting that many modern computers and TVs have standby voltages that remain active even when the device is off.
  • Others assert that devices that are not completely off can still respond to remote controls and keep time, indicating a level of operational capacity.
  • One participant mentions that even appliances like toasters draw a small amount of current when plugged in, due to imperfect insulation in on/off switches.
  • A later reply emphasizes that leakage in cords and house wiring may contribute more significantly to power draw when devices are off.

Areas of Agreement / Disagreement

Participants generally agree that some devices retain functionality when off, but there is no consensus on the extent of this phenomenon or the implications of power draw in various devices.

Contextual Notes

The discussion highlights the variability in device design and functionality, as well as the nuances in how power consumption is measured and perceived. There are unresolved questions regarding the definitions of "off" and the implications of standby power.

is it true that electoronical device are still alive even when they are off? if yes why?

It depends upon the device. The recent generations of computers have a standby voltage which is always on, many TVs and other electronic devices have a similar feature. This allows for soft on/off switches. That means the device is controlled by lower voltages and usually comes up faster.

If you pull the plug they are off cold.

Again this feature depends completely on the device and varies.
 
Yes, it is true.

Devices that are not completely off can:
- respond to a remote control
- keep time
 
There's also the factor that even something like a toaster draws an infinitesimal current when not in use, if plugged in, just because most on/off switches aren't perfect insulators.

If a person is going to THAT extreme I'd say leakage in the cord and for that matter the wiring in the house is more significant.
