Hot Issues Overview - 1 Overview This chapter is designed to highlight unique or highpriority product issues that you should be aware of before servicing the PowerBook 1400. This chapter alerts you to important issues and provides links to other areas in the manual where more complete information can be found. This chapter is not intended to replace other parts of this manual; it merely provides a pointer to pertinent information in those chapters.
Hot Issues Bottom Case Latch Replacement (2/98) - 2 Bottom Case Latch Replacement (2/98) Issue: The latches on the bottom case battery and media bays may come off. The latches are replaceable. Please replace the latches for customers rather than replacing the entire Bottom Case Assembly. Parts Identification: Order Replacement Part 922-3304: Latch, Bottom Case, PB 1400. The latches come in a package of five.
Hot Issues Logic Board Identification (2/98) - 3 Logic Board Identification (2/98) Issue: There are two logic boards with ROM version 3 that could be used in the PowerBook 1400, 117MHz and the PowerBook 1400, 133 MHz units. Because dealers must return the same part they ordered to receive reimbursement, it is important to properly identify the logic board before ordering a replacement. Part Number 661-1188 has ROM U3 (Low, 341S0203) and ROM U4 (High, 341S0204).
Hot Issues Logic Board Identification (2/98) - 4 stock. Since it will work in all the PowerBook 1400 units, this should not pose a problem to customers or Service Providers. Parts Identification: To check the ROMs on the PowerBook 1400, 117 MHz units, remove the factory-installed Memory Expansion Card (the card closest to the Microprocessor Daughterboard).
Hot Issues Door Replacement for PowerBook 1400 CD-ROM Drives (12/ Door Replacement for PowerBook 1400 CD-ROM Drives (12/97) Issue: The doors of the CD-ROM drives used with the PowerBook 1400 media bay may break at the tabs used to attach it to the drive mechanisms tray. These doors are replaceable. Please replace the door for customers rather than replacing the entire CD-ROM assembly.
Hot Issues 1 GB Hard Drives Formatted Improperly (2/97) - 6 1 GB Hard Drives Formatted Improperly (2/97) Issue: PowerBook 1400 computers that shipped with one gigabyte (1 GB) hard drives were formatted improperly. The improper formatting caused 1 GB hard drives to appear to have only 750 MB of total disk space. Solution: This formatting issue has been noted and corrected at Apple's manufacturing site. This issue should no longer be a factor in any new PowerBook 1400 computers.
Hot Issues 1 GB Hard Drives Formatted Improperly (2/97) - 7 Which models shipped with a 1 GB hard drive? Not all PowerBook 1400 computers shipped with 1 GB hard drives. Only the following models shipped with 1 GB hard drives. • M4856 Macintosh PowerBook 1400c/117 • M5576 Macintosh PowerBook 1400c/133 How can I tell if the 1 GB hard drive is formatted improperly? If you aren't sure whether or not the hard drive has been improperly formatted, do the following: 1 Open the hard drive window.
Hot Issues 1 GB Hard Drives Formatted Improperly (2/97) - 8 the drive will need to be reformatted to obtain the full size of 1 GB. How do I reformat the hard drive? If the PowerBook computer has an improperly formatted hard drive, follow the steps below to reformat the drive. Important: Reformatting the hard drive will cause all the data files on the drive to be permanently erased. Be sure to save important files to other media before reformatting.
Hot Issues 1 GB Hard Drives Formatted Improperly (2/97) - 9 3 Run Drive Setup to reformat/initialize the hard drive. 5 Restart the PowerBook and check the hard drive window. The amount of space "in disk" and "available" should total 1 GB. 4 Restore all the software from the PowerBook 1400 CD.
Hot Issues Missing HD Reference File (2/97) - 10 Missing HD Reference File (2/97) Issue: A reference file needed by the system was not installed on the PowerBook 1400’s hard drive during the manufacturing process. As a result, if customers use a Disk Utility program (such as Apple’s Disk First Aid) that addresses this reference file, they will receive an error message. For example, customers using Disk First Aid to verify their hard drive will see the error message, “This is not an HFS disk.
Hot Issues Missing HD Reference File (2/97) - 11 Solution: The “PowerBook 1400 HD Updater” corrects this problem. A Read Me file included with the updater provides customers with step-by-step instructions for installing the updater and explains why they need it. Customers with access to the internet will find two files— “PB 1400 HD Updater 1.0” (the Read Me file) and “PB 1400 HD Updater 1.0.sea,” using the following path: Apple SW Updates/US/Macintosh/PowerBook/PB 1400/ PB 1400 HD Updater 1.
Hot Issues PowerBook 1400: Video-Out Upgrade Kit Ships with Wrong PowerBook 1400: Video-Out Upgrade Kit Ships with Wrong Screws (2/97) Issue: Some of the initial Macintosh PowerBook 1400 8-bit Video-Out Upgrade Kits (M4509LL/A) shipped with the wrong screws. Instead of two (2) short Phillips-head screws, the product was packaged with one (1) long and one (1) short torx-8 screws. Solution: This packaging error has been corrected, and future shipments of the product will contain the correct screws.

Basics Battery Information - 17 Nickel-Metal-Hydride Batteries The PowerBook 1400 Series computers use nickelmetal-hydride (NiMH) batteries. Each battery provides power for up to four hours of work time, depending on the system configuration and battery conservation features employed.
Basics Battery Information - 18 Battery Handling Guidelines The following are guidelines for properly handling the PowerBook 1400 Series batteries: Warning: NiMH batteries contain hazardous chemicals. Send undamaged, dead batteries to Apple for recycling—do not discard dead batteries with other waste. If battery is damaged, do not return it to Apple. Dispose of damaged batteries according to local ordinances. Review battery handling and disposal instructions in Safety Information in Bulletins/Safety.
Basics Battery Information - 19 • Always put the battery cap on the battery when the battery is out of the PowerBook. The battery contacts should not be exposed when the battery is out of the computer. • Do not leave the battery in hot locations (such as the trunk of a car). • Do not store a battery for longer than six months without recharging it. • Recharge batteries only as described in the user’s manual and only in ventilated areas.
Basics PC Card Handling - 20 PC Card Handling Two PC Card slots (also known as PCMCIA slots) are featured in the PowerBook 1400 Series.

Type I and Type II cards fit in either the upper or lower slot of the PC Card unit.
Basics PC Card Handling - 21 slot. When a Type III card is in the lower slot, the upper slot cannot be used. The following are guidelines for properly handling PC Cards: • Use only cards that are compatible with the PC Card unit. Refer to the compatibility information that came with the card. If you cannot find the compatibility information, call the card vendor. • Use an SRAM card for extra storage only. If this type of PC Card is used to start up the computer, an error message will be received.
Basics PC Card Handling - 22 • Before you eject a card, make sure nothing is blocking the card’s slot. • If you want to use the card again immediately, pull it out about an inch more and then push it back in. If you don’t follow this procedure and try to push the card back in to use it again, the card will not engage properly. • Do not pull on a PC Card before it has been ejected out of the slot. Forcing a PC Card out of the slot may damage the computer or the card.
