PowerBook 280c: Global Village Power Up Issue

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.
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.

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.
