What's New

1. Important: The display/analog assembly contains a non-switching power supply preset at a 220V configuration. The voltage selection needs to be manually set by the way of a voltage jumper. If you are operating the computer in a 110V environment, you will have to install the voltage jumper. Refer to "Display/Analog Voltage Setting and LHR Module Instructions" discussed later in this chapter.

Note: The LHR coil (line conditioning module) is used in some international countries. Refer to the Take Apart chapter, LHR topic, for take-apart information.

  1. Important: If you are returning a defective display/analog assembly, it is imperative that proper packaging guidelines be followed. The packing procedure is included with the replacement assembly. Incorrect packaging can result in damaged eMac displays. Please read and follow the directions enclosed in the shipping box of the new display prior to packaging the defective module.Failure to package the defective module according to the instructions may result in liability for the cost of the damaged display.
  2. Important: Do NOT lift, handle, bump, or manipulate the CRT neck/neck board on the Display/Analog assembly. Modules damaged by mishandling are NOT covered by Apple Warranty. Apple Authorized Service Providers can be liable for broken CRT necks due to improper handling. Refer to "CRT Neck/ Display/Analog Assembly Handling Information" topic in this chapter for more information.
  3. The eMac display/analog assembly requires no voltage calibration or geometry adjustment. Should the display appear to require adjustment (focus, color, or brightness) use the "Displays" pane under System Preferences if using Mac OS X. If using Mac OS 9, use the Monitor Control Panel. If you can not make satisfactory corrections with these tools, replace the display/analog assembly.
  4. Important: The microprocessor uses a heatsink/thermal pipe to transfer heat away. Whenever the heatsink is removed, the bottom side of the heatsink and the top of the microprocessor must be cleaned and thermal paste must be applied to the microprocessor. If the mating surfaces are not cleaned and thermal paste is not applied, the CPU may overheat and become damaged. Refer to "Thermal Paste Application" in this chapter.
  5. The hard drive has 3 thermal pads. If the thermal pads become damaged, replace them.
  6. The eMac has an optional stand. Refer to the Upgrades chapter or the CIP procedures for instructions on how to install the stand.
  7. The computer has a Power PC G4 microprocessor, running at a clock speed of 700 MHz.
  8. The computer comes with 128 MB of SDRAM installed. Two DIMM slots support up to 1 GB using 128 MB, 256 MB, or 512 MB DIMMs. The SDRAM modules are PC-100, 168-pin DIMMs.
  9. The computer comes with either tray-loading CD-ROM or DVD-ROM/CD-RW (combo drive).
  1. The 56K fax modem is only available on the DVD-ROM/CD-RW (combo drive) model.
  2. The eMac uses a different A/C power cord; power cords from older iMac models may not fit into the A/ C socket.
