    Not sure where the issue lies....
    updating out fleet of squad laptops--windows updates, Java update, and Malwarebytes update.

    Users reporting GPS not working.
    They all seem to be users on the Sierra wireless NMEA GPS--Panasonic internal (so far) seems to be working still

    when we got these laptops new, I have to do that UBX (dos screen) command to get them to output NMEA strings. It would go thru steps 1-5 and finish/start working as needed

    some of these dead ones I try to run the DOS command and it hangs on step 1 fro about 1 min then errors. it will continue, and look like it re-trys step 1-5 and I shows it completes.

    after all that, its showing GPS signal, but seems to look different than what it should, and it doesn't find any satellites

    I am wondering if the internal GPS isn't jacked, and if there was a "factory reset" I could do on it?

    any other help would be great!
    (of course time is critical-- we have many computers that are down because of this)

    thanks!!!!

    internal gps option that came with the laptop, and internal optional sierra wireless GPS/Verizon card

    (as far as I can tell) :)

    they have both

    so far, with testing, it appears Malwarebytes update and java update do not affect the sierra wireless NMEA port--

    So if they all have both, why not just use the real Panasonic gps and forget the Sierra?

    some of the Panasonic GPS's are "messed up"-- caused by me....back before we discovered /dos fix thing.

    that's why I was looking to see if there was a "reset" string we could run on the internal gps to reset it back to factory

    Are they Leadtek or something else?

    The three uninstalled ones that I have here are all Leadtek.

    If they were for instance Ublox, then U-center has tools for factory reset.

    There are warnings that communicating with some GPS units can break them.* So use the right tool for the job would be my advise.

    *Here is a gpsd html with a lot of links.

    pretty sure ublox.
    had to run that gps/ublox/dos thing to get it to output GPRMC (apparently what we need)
    now it wont re-flash and seems to show data coming in to the gps, but never gets a location
