Default pass through power cable for laptop?

Hi all,
I'm looking for a short pass through cable for my HP laptop so that when I
trip over the cable the power cable easily disconnects from the pass through
rather than have the laptop fall off the table smashing into the floor and
... tripping me up ... and perhaps breaking my wrists while a try to break
my fall. Also I want the cable to 'break' instead of the jack which can be a
difficult fix.

Tripping over laptop cables is so common I'm surprised that manufacturer do
not provide a pass through cable as standard equipment if only to avoid
getting sued.

Sued? You can't be serious.

How about a big velvet rope that cordons off the area you're
allowed to walk though?

All kidding aside, use an extension cord and put a rug over
the cable on the floor so your feet don't snag it.

You must have a different definition of a power pass-through. See:

http://www.pcguide.com/ref/power/sup...ordPass-c.html
http://www.gigaweb.com/files/product...wr-pslib-3.jpg
http://www.pacificgeek.com/largeimag...3PINTO4PIN.jpg

Got an example of what YOU mean?

For the power cords where the transformer & converter is a brick somewhere
in the middle of the cord and has a cord plug into the brick, that cord
plugs in more than snuggly enough that if you trip on either end of the cord
that it will still behave as one cord. So your laptop would still go
flying.

Spend 21 days deliberately lifting your feet as you walk and it will become
habit. Do NOT use your Blackberry, iPod, cell phone, or any other gadget
while you are walking (and definitely not when driving where you can hurt
others). Look where you are walking. Don't behave like a child wandering
through Disney World that walks while gawking at attractions to the side.
Break the habit of looking at to whom you are listening and continue to look
forward when moving. Learn to stop when [you choose to be] distracted by
someone asking a question.

Baseball bat manufacturers, by your logic, should get sued when *consumers*
leave them lying on the ground or like when they get tossed after the batter
makes a hit and starts running. Of course, lots of cases get tossed out of
court as frivolous. Too bad any case deemed frivolous doesn't automatically
fine the plaintiff for wasting the courts time and harassing the defendant,
but then we'd need a legal definition of frivolous that would deter the
licentious *******s in the first place. Punish those who attempt to abuse
the court system AND without the need to involve a lawyer to deem a case as
frivolous.

Any cord that would break (at a connector) because you snagged it with your
shuffling feet would be of no value to laptop owners. The slightest
movement of the cord would break the connection, and that would include when
the user moved around the laptop. The connection of the power cord's prongs
into the wall outlet is just friction of the tangs pushing past other
springy tangs. The wall outlet connection is not secure ... and you want
less friction than that which renders the power connection even worse for
reliability. And are you going to afford buying this special easy-to-break
power cord for every laptop owner, every lamp owner, every vacuum cleaner
owner, and for every owner of any device that uses a cord to receive its
power? No one is going to waste time with losses of power and the expense
of an unreliable cord because of your clumsiness.

If anyone gets sued, it will be by the laptop owner for damaging their
laptop. Regardless that it was an accident, you still caused the damage so
you are still liable for remuneration, replacement, or repair of what you
clumsily damaged. If you are repeatedly in an environment that is fraught
with cords lying across your path, like in a class or training room, start
investing in throw rugs or move the tables against the walls (where are the
wall outlets).

Tripping is common to you. Tripping is not common.

jeeeeesh ... relax why don't you?!

It occurs to me that the design of mains electrical sockets here in the UK
make for a very firm attachment to the wall compared to the one you
describe. This may add to the severity of tripping the power cord here ....
but mostly the damage is done to the power jack in the laptop, and I've seen
it and heard about it happening hundreds of times.

Apple have a magnetic power cord connection to their laptops so that it
comes off the laptop very easilly, I believe, and sounds like a great idea
designed specifically to mitigate the problem. so I seriously doubt that
tripping the power cord is limitted to just me and people I know ;)

but .. soon enough we will have wireless power charging for devices and
obviously I'll be the main and possibly the only customer they have in mind
for that.

The picture on your second link (pwr-pslib-3.jpg ) is the kind of thing I
have in mind .. but at the laptop end.

hmm .. I wonder if I can make one .. the problem being sourcing the
connections.

You can solve the laptop problem by wrapping the cord around a table leg
and tying a not in it. Can't break the laptop.

You can solve the tripping problem by routing the wire somewhere you
don't walk...or paying attention to where you walk.

How about severing the AC-DC adapter's lead to the laptop
(after the brick portion when it's already converted to low
DC voltage) and soldering on a standard DC barrel socket
rated for enough current (4A for this one), to the laptop
end of the wire
http://search.digikey.com/scripts/Dk...ame=CP-024B-ND

.... and to the other wire end going to the PSU brick, place
the mating DC barrel plug, (also checked to ensure it's
rated for enough current, 5A for this one):
http://search.digikey.com/scripts/dk...me=CP3-1001-ND

It won't come apart quite as easily as some of Apple's do,
but it may come part easier than either of the ends
currently do and some of Apples have wire and contact
retraction issues making them problematic.

However, I still like the idea of just using an extension
cord and putting a rug over the cord where you walk through
the area.
