TOPIC

    The PowerBook Duo 280 and 280c have seen intermittent power up difficulties with Global Village PowerPort Mercury modems installed. Affected units have a difficulty starting up on battery power. Most cases also have a large memory card installed.

DISCUSSION

    Global Village recommends loading their modem software before installing their modem. You may need to start up using AC power the first time after installing the modem, but after that first startup, things should work fine. Here are the recommended steps to correctly install the modem.
      1. Make sure all Express Modem software has been removed (if applicable).
      2. Install Global Village modem software (v 2.08a or 2.5) BEFORE installing the modem.
      3. Shut down the PowerBook Duo and install the Global Village Mercury modem following the installation instructions provided by Global Village.
      4. Start up the PowerBook Duo with AC adapter plugged in or in Duo Dock. You may have to try the reset button two or three times to get the machine to start up. When the PowerBook has completed the startup process, the Global Village extension downloads new power management code to correct the situation.

    If you have a PowerBook with the modem installed already, Step 2 and 4 above can be done with the same end result. The only problem is getting the unit to start up to load the modem software from disk, and then restarting again to download the new power management software. The main reason to load the modem software first, is to avoid the symptoms associated with trying to get the unit to startup with Global Village modem and no Global Village software installed.

    Other possible workarounds include:
    • Reset the power manager by holding these keys down while starting up: Command-Escape-d. This power manager is similar to pressing the power button in the back of the computer for 30 seconds.
    • Reset the power manager by holding these keys down while starting up: Command-Option-front power on key. This power manager reset is similar to disconnecting the internal backup battery of the computer.
    • Install an Apple Express Modem.
    • Replace the large RAM card with an Apple 8 MB RAM card.
