TOPIC
What are the new changes in the LaserWriter 8.4.2 driver that is installed with Mac OS 7.6?
DISCUSSION
LaserWriter driver version 8.4.2 had one single fix relating only to Adobe's PageMaker v6.0 and v6.01:
- A problem was resolved where one extra blank page was printed at the end of every print job.
The updated version of Desktop PrintMonitor v2.0.2 also shipping with LaserWriter 8.4.2 in System 7.6 has a couple of fixes as well. They are:
- Error type 15 and/or -192 occurring on Mac OS computers with a PowerPC card. These errors only occurred when trying to create, open, or print to a desktop printer.
- Finder getting confused when a folder's directory ID matches that of the PrintMonitor Documents folder. Finder may not display that folder or its contents, and other strange behavior may occur with that specific folder.

Contents -------- * PowerBook Computers: How Cold Temperatures Affect Them * PC Setup Unimplemented Trap, Error Message * PowerBook 3400: Ethernet/Modem Card Questions -------------------------------------------------------------------------- PowerBook Computers: How Cold Temperatures Affect Them -------------------------------------------------------- TECHINFO-0021045 TOPIC ------------------------------------------------------------------- How can a cold environment affect a PowerBook computer's Power Manager? DISCUSSION --------------------------------------------------------------- Issue -------- When a PowerBook computer's Lithium backup battery is exposed to cold temperatures it may cause the PowerBook computer to not keep time or not power on. Description ------------ A PowerBook computer's Power Manager and Parameter RAM (PRAM) are maintained by the backup battery when the PowerBook computer is either Shut Down or in Sleep mode. The backup battery used in PowerBook computers is a Lithium battery which behaves differently compared to other battery types in both low-voltage and cold temperature situations. Lithium batteries when exposed to a cold environment (less than 45 degrees Fahrenheit or 7 degrees Celsius) may either stop sending voltage completely or they may "pulse" full voltage. This inadequacy or inconsistency of voltage sent from the backup battery can corrupt the PRAM and/or Power Manager of a PowerBook computer. Solution --------- A PowerBook computer which has recently been exposed to a cold environment (such as the trunk of a car, in a classroom at a school which may not be heated overnight, and so on) should be placed in a warm environment where it can be warmed to room temperature (more than 50 degrees Fahrenheit or 10 degrees Celsius) before you attempt to power it on. If the PowerBook computer still does not power on after being allowed to warm up, you should reset the ***Power Manager***. Each model of PowerBook computer has different methods for doing this. For more information on resetting the Power Manager for your PowerBook computer model see the Tech Info Library article 0014449, titled "PowerBook: Resetting Power Manager". *** WARNING ***** Power Manager Reset procedures for all of the Macintosh PowerBook computers will permanently remove a RAM disk, if present, and all of its contents. -------------------------------------------------------------------------- PC Setup Unimplemented Trap, Error Message -------------------------------------------- TECHINFO-0021078 TOPIC ----------------------------------------------------------- After installing Mac OS 7.6 and PC Compatibility 1.5 software, everything was working fine. However, after installing Open Transport PPP 1.0 and restarting my computer, I get this error message, "Sorry, a System Error Occurred. PC Setup, Unimplemented Trap." What is wrong? DISCUSSION ------------------------------------------------------ During the installation process, the PC Setup preferences file was corrupted. To resolve this, you need to throw the PC Setup preferences file in the Trash, empty it, and restart your computer. A new PC Setup preferences file will be created with default settings. -------------------------------------------------------------------------- PowerBook 3400: Ethernet/Modem Card Questions ----------------------------------------------- TECHINFO-0021065 TOPIC --------------------------------------------------------- Is the modem that came with my PowerBook 3400 series computer made by Apple or Asante? Who supports it? If I had bought a PowerBook 3400 series computer that did not come with this modem, could I buy it later from Apple? Do I have to use the "dongle" even if I'm not using Ethernet? Tell me about the phone cord supplied with the computer for this pre-installed, internal modem. Do I have to use this one? Can I not use just a regular phone cord like I have at my house? What will happen if I use a four-wire cord? DISCUSSION ---------------------------------------------------- Modem Technical Support ----------------------- The combination Ethernet/modem card included in most PowerBook 3400 series computer configurations in US and Canada (and in all configurations sold in Japan) is actually produced by Asante. However, it is sold as an Apple-labeled (not Asante-labeled) part when it is included in a PowerBook 3400 series configuration. Apple is responsible for all service and support for these configurations. If US or Canadian customers purchase a PowerBook 3400 series computer without the internal Ethernet/modem card included, Apple does not supply this card as a stand-alone item for later purchase. However, the card can be purchased from Asante. When sold by Asante, the card is Asante-labeled (marked as such on the card) and supported by Asante, not by Apple. The Ethernet/Modem Adapter --------------------------- You do not need to use the Ethernet/modem adapter (dongle) which is supplied with your PowerBook 3400 series computer if you are using only one function at a time. Either a modem cord or a 10baseT Ethernet cord can be plugged into the single port on the back panel of the computer. The port will recognize the type of cable that is plugged into it and it will act accordingly. The adapter is only needed if you want both Ethernet and modem at the same time. The Phone Cord --------------- The phone cord supplied with PowerBook 3400 series computers is a two-wire (single-line) phone cord in which only the center two pins are connected. The cord has a label on it instructing you to use only a two-wire (single-line cord) for the PowerBook 3400 series internal modem. If you lose or break the cord it should be replaced with a two-wire cord (available at most electronic stores). If you use a four-wire phone cord, in most cases, it will work just fine. However, it is recommended that you use the two-wire cord because, if the telephone outlet plug to which you connect the cord carries two phone lines, including a second phone line over the outer pins of the RJ-11, the second phone line will be connected to the Ethernet circuit. Although this should cause no permanent damage, the second phone line will be taken "off hook" and may cease to function properly while the phone cord is plugged into the PowerBook 3400 computer. If when you plug in your modem your other phone line stops working, check to make sure you are using a two-wire (single-line) phone cord. A four-wire phone cord should work fine with the Ethernet/modem adapter (dongle). The dongle only has two pins which hook up to the wires on the phone jack. A four-wire phone cord will not take the second line "off hook", but you cannot access the second line from your PowerBook 3400 series computer if you use this type of cord. -------------------------------------------------------------------------- The "Information Alley" is a publication of Apple Computer, Inc., Service and Support Engineering.
