Question about Logitech Cordless TrackMan Optical Trackball

2 Answers

Logitech Cordless Optical Trackman loses its connection

Computer is an HP Pavillion notebook running 32 bit Vista SP2.

For two years the Logitech Cordless Optical Trackman has had no problems running all the time, staying connected endlessly without hardly ever having to push the "connect" button on either the receiver or on the bottom of the trackball itself. Hardly ever.

Suddenly, today, the darned thing just stops working and I have to push the "connect" button on the bottom of the trackball (not on the receiver) to get it going again. Sometimes it happens a couple of times in an hour...

...this, suddenly, today, after never having such problems.

Its batteries are fine. No physical obstructions. Everything's clean. Physical USB connection is good..

Any ideas?

    (From the fellow who posted the question)

    Actually, it turns out to have been simpler than that. To my astonishment, it was, simply, low batteries...

    ...but I missed that because the Lotitech SetPont ver 4.72.40 software said, right to the bitter end, that the batteries were good. It never even occurred to me 'til I got up this morning and thought about it for a while while waiting for my coffee to finish brewing. I pulled them out and put them onto a battery tester (that's capable of inflicting a genuine load on the batteries for a more accurate test) and, sure enough, they were bad... only about 10% left in them.

    I put them back into the trackball to see if SetPoint would still see them as good, and suddenly it didn't. Having removed them and then put them right back in, SetPoint suddenly correctly saw them as bad.

    I replaced them with brand spankin' new ones, and the problem instantly went away. Everything's been find so far all day. Yesterday, by this time of the early afternoon, I had hit that "connect" button on the bottom of the trackball about ten times or more. Today, not once.

    One thing that's different is that for the first time, I've used Duracell (the "Coppertop") batteries instead of Evereadies. Most people don't realize it, but one of the ways that Duracell manages to make its batteries outlast Evereadies is by choking-down the voltage a little. Evereadies ship from the factory at almost exactly 1.5 volts; Duracells ship at more like 1.25 volts. Most battery-operated devices will tolerate that kind of variance, so it doesn't really matter much. However, I first discovered the difference it when my wife (who co-owns two restaurants) complained that Duracells wouldn't work in the electronic thermometers, but Evereadies would. So I looked closely at the thermometer specs and there was a note about how important it is that Duracells aren't used because of the voltage difference; that the thermometers required 1.45 to 1.55 volts, exactly, and wouldn't toerate even a fraction of a volt more or less.

    So this now leads me to wonder if the SetPoint software is thrown off somehow by this difference. Since I bought the trackball, I've only used Evereadies... not because I particularly like them (I don't), but because I had a whole box of 'em that I wanted to use-up so I could go buy a big box of Duracells and start using those. And I did use them up, and I did buy and start using the Duracells...

    ...and look what happened.

    I'm not saying, for sure, that that's it; but it's interesting that the SetPoint software *ALWAYS* accurately reported low batteries in the trackball (and in the keyboard, too) prior to this. But now, suddenly, when I start using Duracells, the SetPoint software reports, right up 'til the batteries are down to maybe 10% of their life, that they're 100%.

    Something to keep an eye on, no?

    Anyway, thanks for the help! Your suspicion was clearly the most logical; and, in fact, even before I read your response, I was already wondering if the store where I bought it still carried them.

    But today I got lucky. It was simply the batteries.

    I'm going to try this set of Duracells and see if it happens again. Then, if it does, I'll go back to Evereadies and see what that does.

    One good thing that came out of it all was that the trackball and its receiver got a helluva' good cleaning yesterday! Gotta' like that. [grin]

I DID buy a new one actually! They don't last long, about 6 mos-then it starts getting hard to move the ball around. I've even polished the points with a dremel. ANYWAY...The new one does the same thing. New trackball, new batteries. It worked fine before. Now, ever time I'm afk a while it won't respond. The connect stuff does nothing. Only rebooting seems to fix it and who wants to have to go through that **** all the time?!
