    Hi guys,

    I have T400 with ATT broadband card (F3507G). I posted a thread earlier about my T400 getting freezed when I wake it from sleep. I tracked down problem to ATT card active connection + battery and sleep mode. I observed if I am browsing internet with this card and I close the lid of my notebook, wait 2 mins. and then open it, everything freezes. I mean I can't do Ctrl Alt Del or click anything. Sometimes screen is just black and sometimes its stuck with whatever its showing on screen ( even brightness control levels too)
    I am having this problem on Vista. The problem occurs more frequently if I am running notebook on battery.

    Can anyone test their T400 if you have ATT card + service and Vista?

    Is it possible the card is bad or the drivers are bad?

    thanks

    I have not have this issue. If I suspend while AT&T card in use, it resume fine (just disconnected), and I need to reconnect. (I'm 64 bit Vista)

    Do this ONLY happen when you have a WWAN connection, or does it happen at other times? I ask because I have had Dells and HPs that exhibited that behavior, and it is often something else.
