Mac Forum / General / Portable Macs / September 2004Power adapter - is it bad to keep it plugged in?
When I unplug the notebook from its power adapter, is it okey to leave the other end plugged in and powered on? I never thought about it until I got a Sony Vaio Z1WA with a bright green light power-on indicator... Don't use the email address in the header, it's a spam killer.

It's basically like any other wall-wart: it'll stay a bit warm, and consume a few milliwats, but that's about it. SignatureLater. johajohn@indianahoosiers.edu 'indiana' is a noun. Leave only the noun and .edu after the @ to reply Pismo: 2000-2004 RIP 15" AlBook: 2004-The PowerBook is dead!

Many people consider it risky to unplug the computer end of the cord while the wall end is still connected. G SignatureStandard output is like your butt. Everyone has one. When using a bathroom, they all default to going into a toilet. However, a person can redirect his "standard output" to somewhere else, if he so chooses. - Jeremy Nixon > > When I unplug the notebook from its power adapter, is it okey to leave the > > other end plugged in and powered on?

That way shocks are at the wall/adapter, not at the computer which is more precious and more costly to repair in case of sparks. I leave my adapter plugged in at my desk if I'm moving the 'Book around my house. When I return it either simply because I am ready to or because it needs a charge, everything is set up for an easy reconnection of the book to the power supply. My 'Book is over a year old and thriving on this regimen. I had not done this with my previous laptops because they didn't hold a charge nearly as long, so the cord generally had to come with me. >>> When I unplug the notebook from its power adapter, is it okey to leave the >>> other end plugged in and powered on?

The one bad thing about it is that the computer plug in is pretty easy to damage so you don't just want to leave it laying out where it can be damaged by setting something on it or even stepping on it like I did. > The one bad thing about it is that the computer plug in is pretty easy to > damage so you don't just want to leave it laying out where it can be > damaged by setting something on it or even stepping on it like I did. Did you misplace that cute little plastic cap? I myself had to buy another power adapter after my iBook slipped on the floor and hit it with the adaptor's plug. Very flimsy design. :( SignatureVadim Zima Certified Russian Translator and Court Interpreter www.zima.net > Did you misplace that cute little plastic cap? > I myself had to buy another power adapter after my iBook slipped on the > floor and hit it with the adaptor's plug.

You want to think about that one for a second? If you plug/unplug the computer end while the wall end isn't plugged in, how will the computer get a shock? Better: Can you provide a citation for that being the way "Apple tells you to do it." I find no such advice in the manual for my iBook or in a cursory search of Apple's support site. G SignatureStandard output is like your butt. Everyone has one. When using a bathroom, they all default to going into a toilet. However, a person can redirect his "standard output" to somewhere else, if he so chooses. - Jeremy Nixon When the adapter is connected to the wall sometimes it sparks for a second. Ditto when it is removed from the wall. I'm certain it is better to let it spark while a computer isn't attached. (Attaching to the computer doesn't cause additional sparking.) If you first attached the wire to the computer, then to the wall, and it sparked at the wall, that spark might possibly somehow travel through the wire and damage the computer. I don't remember where I first learned that, and I have no need to research it. > > > > When I unplug the notebook from its power adapter, is it okey to leave > > > > the other end plugged in and powered on?

It certainly can. > If you first attached the wire to the computer, then to the wall, and it > sparked at the wall, that spark might possibly somehow travel through > the wire and damage the computer. > > I don't remember where I first learned that, and I have no need to > research it. It would be nice if you're going to offer it as advice and rely on a fairly significant authority (the vendor) for support if you could actually supply the supporting data.

Nevertheless, regardless of the 'why', I checked her out on the 'how' and she is correct. > > If you first attached the wire to the computer, then to the wall, and it > > sparked at the wall, that spark might possibly somehow travel through [quoted text clipped - 6 lines] > fairly significant authority (the vendor) for support if you could > actually supply the supporting data. Macintosh PowerBook User's Manual (034-0426-A) © 1998 [This is the one that came with my Wallstreet.] Chapter 1, 'Setting Up' page 20, 'Plugging In the Computer' 1. Plug one end of the power cord into the power adapter and the other end into an outlet or power strip. 2. Plug the power adapter plug into the power adapter port (marked with the icon ...) on the back of the computer. ------ So, there you have it. QED. cheers, Henry |
