I had her read the power adapter the other day and she read off 19.5v @ 3.4?amps. So that would be the 65 watt pa-12 one I guess. And that makes sense since all of the laptops I have worked on with Celeron single core CPU virtually all are 65 watt supplies. And I worked on hers a few months ago and I remember it was a single core Celeron. Dual core or AMD processor laptops are almost always 90 watts or greater. Sure hope you are right about the center is positive. I hate to give her a supply and it is reversed in polarity. As that is likely to make the motherboard worthless. And thanks for all of your help. -- Bill Gateway MX6124 ('06 era) 1 of 3 - Windows XP SP2

From: William R. Walsh on 16 Apr 2010 18:31 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. William
