Symptom Charts

How to Use the Symptom Charts

The Symptom Charts included in this chapter will help you diagnose specific symptoms related to the product.

The steps to solve a symptom are listed sequentially. You might not need to perform every step before the symptom is solved. Start with the first step, and then test for the symptom. If the symptom persists, replace any modules you removed, go to the next step, and test again. Continue down the list until the symptom is solved.

AirPort Card

AirPort Card not recognized

The battery won't charge

1 Use Software Update control panel or see the Apple Software

Updates web page to make sure the latest version of AirPort

software is installed. 2 Boot using Mac OS All extensions setting. 3 Reseat AirPort Card. 4 Remove and reinstall the AirPort software. 5 Replace with known-good AirPort Card. 6 Replace logic board.

Battery

1 Remove any connected peripherals. 2 Try known-good power outlet. 3 Try known-good power adapter and power cord. 4 Try known-good battery. 5 Turn off the computer. Reset the power manager by pressing

the reset button (located above and right of the Audio/Video

port). Wait five seconds before continuing. Press the power

button to start the computer.

Note:

Make sure the reset button is not caught under the

button opening.

Warning: Resetting the power manager will permanently remove a RAM disk, if present, and all of its contents. You will also need to reset the date and time (using the Date & Time control panel).

6 Replace logic board.

Troubleshooting Symptom Charts/Error Beeps - 2

Error Beeps

The computer automatically performs a power-on self test when it is turned on after being fully shut down (not a restart). This section describes what to do if beeps are heard during the startup.

Note:

The iBook (Dual USB) and iBook (Late 2001) have one memory expansion slot that accepts a 1.25-inch (or shorter) PC-100 compliant, SO-DIMM memory card. Refer to CustomerInstallable-Parts Memory Replacement instructions for removal and installation.

Computer beeps once at startup

Computer beeps twice at startup

Computer beeps three times at startup

Computer beeps four times at startup

1 One beep means that no RAM is detected. 2 If a RAM card is installed in the expansion slot, remove it and

put in known-good and compatible RAM and restart.

• If symptom does NOT repeat, replace RAM card.

• If symptom repeats, replace logic board.

3 If no RAM card is installed, replace logic board.

1 Two beeps means that EDO memory is installed in the

expansion slot. The iBook does not accept EDO memory.

2 Replace RAM card with known-good and compatible RAM and

restart.

• If symptom repeats, replace logic board.

1 Three beeps means that no RAM banks passed memory testing. 2 If a RAM card is installed in the expansion slot, remove it and

put in known-good and compatible RAM and restart.

• If symptom does NOT repeat, replace RAM card.

• If symptom repeats, replace logic board.

3 If no RAM card is installed, replace logic board.

1 Four beeps indicates a bad checksum for the remainder of the

boot ROM. The ROM (which is located on the logic board) is bad.

2 If a RAM card is installed in the expansion slot, remove it and

put in known-good and compatible RAM and restart.

• If symptom does NOT repeat, replace RAM card.

• If symptom repeats, replace logic board. 3 If no RAM card is installed, replace logic board. Related articles: 58442: Power On Self-Test Beep Definition - Part 2 95136: iBook (Dual USB): Installing or Replacing Memory

LCD anomalies Go to : Pixel anomalies

A certain number of pixel anomalies are inherent in liquid crystal display technology and vary by many factors, including type of technology.

Many anomalies observed by customers are considered normal or are the result of lint or dust particles resting on the front of the display. It is important to understand what type of anomaly a customer sees in order to determine whether further analysis is necessary. In many cases all that may be necessary is a gentle cleaning of the display face using the provided cleaning cloth.

IMPORTANT : Providing a replacement display to satisfy a customer may not be effective because the

replacement display may have more or different types of visible anomalies than the original display, and still be within specifications.

Knowledge Base Article 22194 can be indicated to customers as public explanation from Apple side.

Industry standards used by all manufacturers are specifying a certain number of minor defects, as generally accepted or creating an acceptable situation. This means that the level of quality in the industry includes some level of pixel-defect.

The following sentences can be used with customers’ complains

Copied from SONY documentation (Sony VAIO web Support)

• High precision technology is used to manufacture these LCDs to maintain a high standard of operation. However in all LCD panels there may be a small number of pixels that do not change color. This is a normal occurrence for all LCD displays from all manufacturers and should not be noticeable or objectionable under normal operation.

• Sometimes the pixels are noticeable only during booting or on an all white or all black screen.

• The LCD screen is manufactured using high precision technology. However, there may be some tiny black spots and/or bright spots (red, blue or green in colour) that constantly appear on the LCD screen. These spots occur normally in the manufacturing process and do not effect the recorded picture in any way. Effective number of pixels is 99.99% or more.

Copied from COMPAQ documentation (Compaq FAQ on Compaq’s web Support)

• Note that if you have the smallest number of dead pixels, your replacement display panel may have more, use your judgement before deciding that you have a defective panel.

Copied from DELL documentation (Dell web : http://support.euro.dell.com/fr/fr/kb/document.asp?DN=FA1018431)

• The liquid crystal display (LCD) screens built into portable computers and flat-panel monitors are manufactured using rigid quality control standards. These manufacturing standards ensure that the LCD screen is clear and viewable.

• During the manufacturing process, it is not uncommon for one or more pixels to be fixed in an unchanging state. The visible result is a fixed pixel that appears as an extremely tiny discolored spot, either a dark spot or a bright spot.

Copied from TOSHIBA documentation (Toshiba web Support)

• Due to current manufacturing methods and the high number of transistors in the TFT Color LCD, a few nonconforming pixels may be visible. There are over a million transistors in a typical TFT screen. When any one of those transistors is not lighting as designed, the pixel is called nonconforming. Nonconforming pixels typically appear as tiny colored dots (red, blue, green, etc.) or as black dots in contrast to the projected background color of the LCD module.

• Quality inspections, performed by the LCD module manufacturers, include limits for nonconforming pixels. Nonconforming pixel limits (10 to 18 pixels) are set solely by the LCD module manufacturers and not by specific computer manufacturers. These limits are defined by the manufacturing processes and are specific to screen characteristics which include : * physical size of module. * display type (SVGA, XGA, VGA). * screen resolutions available.

• LCD Module manufacturers continually strive to upgrade processes used in manufacturing as well as the Quality Specifications which include the limits on nonconforming pixels allowed for LCD modules for use in portable computer displays.

(End

Pixel anomalies

When speaking with Apple Technical Support, it may be necessary to use a pocket microscope, jeweler's loupe, or other magnifying device to properly identify and count each subpixel anomaly.

Displaying all white, red, green, and blue screens makes locating and viewing pixel anomalies easier. A subpixel that is always on should be referred to as a bright subpixel anomaly. A subpixel that is always off should be referred

to as a dark subpixel anomaly. When necessary, portable and display products may be dispatched for evaluation by the Apple Repair Center.
