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. William

(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.

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. |
