Dell 610 power polarity?

My niece's Dell 610 laptop power adapter was chewed up by her dog. She
asked me if I had a spare one she can borrow. Which means I'll never see
it ever again. lol

A spare DOG?

But if the center pin is positive, I have some generic ones that should
work without modification (19v, 3.5A). So does anybody know for sure?

Hi!

you don't have to believe me. you can have her scan or take a
picture of her adapter and email it to you...

I just turned over a PA-10 and looked. There's no indication of the
polarity
printed on mine. There are three contacts, one outer ring, an inner ring
and
a center pin. One of these (don't know which one) will be for serial data
transfer. Perhaps some units are labeled. I'd proceed with caution until
it
can be confirmed. (Dang. Where's my voltmeter?)

If you use a supply that is suitable but does not have the serial data
link,
the machine will complain about this at POST time (and Quickset may notice
later, if it's installed and running). The machine may also refuse to
charge
its battery.

AFAIK, the center pin is the serial data link, and only know that from trial
and error. (The pin broke on one of mine, and while it still works, it
complains at POST and won't charge the battery as stated above. Using the
picture that Chris provided, I would assume this means the inner ring is
positive, and the outer ring is negative.

Hi!

look more closely. *every dell unit i have ever seen has it marked
on there. *though to see since the label is packed with so much
regulatory information for compliance with just about every
country...

Well, I finally turned it over again and had another look. Mine
definitely doesn't have a polarity marking on it. (It does have the
mess of regulatory text however!)

Thanks for the scan. I'm sure the OP found it helpful as well.

hello guys ...


its really nice and informative post....


i just liked it....


thanks for your information guys ...........

btw - my Latitude C-610 has 3 pins - but 3 tiny flat blades vs round
"pins" -

SO - you might check if it the laptop is - C version or the D version.

Our family has gone thru a couple of PA-6 power bricks for these Dell
C-610's.
When using on your lap - sitting in the family room -
as the line filter tends to bend the power cord down at the laptop connector
and over time - breaks the wires inside.
I've carefully soldered them and super glued them stiffer... for awhile.

BTW - I noticed that the 90w version power brick caused some switching
spikes on the TV,
but the 65w power brick didn't -
Must be the difference between switching vs brute force ferrous.
