Laptop adaptor question

  SonnyB 20:06 15 Aug 07

I have a general question about laptop adaptors. I have a laptop which I use occasionally whic I connect to its adaptor only when I use it. However my question is this: Does it harm the adaptor if it is continuously plugged into the mains?

Not sure about adapters for laptops, all I can say is that the small transformer that operates my front door chime has been switched on permanently for the last 27 years. I presume that your adapter is in an awkward position that prevents it being turned off.

Yes, it is. It is far more convenient to just leave it plugged in the same way that you would leave a pc plugged into the mains. I am sure no-one unplugs their pc for the night!
Surely adaptors are the same except the power supply is external.
