Model Differences

The external housing of the PowerBook G4 (12-inch 1.33 GHz) model looks the same as the PowerBook G4 (12-inch DVI) model. Both have a mini-DVI port (shown below).

The mini-DVI port is used with an adapter cable to connect the computer to a monitor, television, VCR, or other video device. The adapter cables that can be used with this port include a mini-DVI-to-DVI adapter, a mini-DVI-to-VGA adapter, and a mini-DVI-to-S-Video adapter.

To distinguish the PowerBook G4 (12-inch 1.33 GHz) model from previous models, check the processor speed and note the latches in the battery bay.

This computer model includes two latches inside the battery bay. These latches help secure the top case to the computer. Refer to the Top Case procedure for more information.

Procedure

Warning:

The glue used in this procedure can bond instantly to skin. Do not touch the glue. In the event of contact, review the safety instructions at the end of this document. For additional information, refer to the glue manufacturer:

Elmer's Products, Inc.

Columbus, OH. 43215-3799 www.krazyglue.com

1. Place the computer upside down on a clean, lint-free cloth or other nonabrasive surface.

2. Select a foot from the kit that matches the plug on the bottom case. (Refer to the images shown in the table.) Do not use a foot that does not match.

3. Make sure the plug area on the bottom case is clean. If any portion of the soft rubber foot remains, remove it so that only the hard plastic plug is visible (as shown below).

Battery Plug Case Plug

Important:

Notice the inner ring of the plug. When positioning the foot, make sure the textured plane of the rubber foot fits into the compatible ring in the plug. This ensures a balanced and level fitting.

Warning:

GLUE IS AN EYE AND SKIN IRRITANT. BONDS SKIN INSTANTLY. Do not touch the glue at any time. Before opening the glue, review the safety instructions at the end of this document.

Important:

The glue tube included in the kit is sealed until first use. Do not break the seal until you are ready to use the glue. To break the seal, hold the tube upright and away from you. Place the hollow nozzle cap on the tube and tighten it all the way down. The tube is then ready to dispense the glue through the nozzle cap.

5. Apply one drop of glue to the plug on the bottom case. Do not spread the glue.

6. Using tweezers or needlenose pliers, carefully position the new foot so its textured surface fi ts into the inner ring of the plug.

7. Using the end of the tweezers or pliers—not your fi nger—lightly press and hold the foot in place for 30 seconds.

8. Before turning over the computer, allow the glue to set for at least 15 minutes.

9. Discard the tube of glue.

SAFETY INSTRUCTIONS:

GLUE IS AN EYE AND SKIN IRRITANT. BONDS SKIN

INSTANTLY. Contains ethyl cyanoacrylate. Avoid contact with skin and eyes. If eye or mouth contact occurs, hold eyelid or mouth open and rinse thoroughly but gently with water only for 15 minutes and GET MEDICAL ATTENTION. Liquid glue will sting eye temporarily. Solidi fi ed glue may irritate eye like a grain of sand and should be treated by an eye doctor. If skin bonding occurs, soak in acetone-based nail polish remover or warm soapy water and carefully peel or roll skin apart (do not pull). Contact through clothing may cause skin burn. If spilled on clothing, fl ush with cold water. Avoid prolonged breathing of vapors. Use with adequate ventilation. KEEP OUT OF REACH OF CHILDREN.

PowerBook G4 (12-inch 1.33 GHz) Trouble Symptom Charts

When displaying a single color over the screen area, the LCD panel shows one or more pixels that are not properly lit

Active-matrix LCD technology uses rows and columns of addressable locations (pixels) that render text and images on screen. Each pixel location has three separate subpixels

(red, green, and blue) that allow the image to be rendered in full color. Each subpixel has a corresponding transistor responsible for turning the subpixel on or off.

There are typically millions of these subpixels on an LCD display. For example, the LCD panel used in the Apple Cinema HD display is made up of 2.3 million pixels and 6.9 million red, green, and blue subpixels. Occasionally, a transistor does not work perfectly, which may result in the affected subpixel being turned on (bright) or turned off (dark). With the millions of subpixels on a display, it is quite possible to have a low number of faulty transistors on an LCD. Therefore, a certain number of subpixel anomalies is considered acceptable. Rejecting all but perfect LCD panels would signi fi cantly increase the retail price for products using LCD displays. These factors apply to all manufacturers using LCD technology—not just Apple products.

To determine whether or not the display has an acceptable number of pixel anomalies, follow the steps below:

1. Set the display image to one of the following colors: all-white display, all-red display, all-green display, or all-blue display.

2. Using a jeweler’s loupe, pocket microscope, or other magnifying device, identify and count each subpixel anomaly:

• Bright subpixel anomaly = subpixel that is always on

• Dark subpixel anomaly = subpixel that is always off

3.

Important:

Check the number of subpixel anomalies with the following chart:

LCD Size

(inches)

Acceptable Number of Subpixel

Anomalies

Bright

12.1 to 15.2

up to 3

Dark up to 5

Combination up to 7

Replace the LCD Panel

Bright

4 or more

Dark

6 or more

Combination

8 or more

4. If the number of subpixel anomalies exceeds the acceptable number listed in the chart, replace the LCD panel.

5. If the number of subpixel anomalies is acceptable, explain to the customer that the pixel anomalies are within speci fi cations, and no repair is necessary.

Important:

Do not release the specifications to customers. Instead, inform them that a certain number of subpixel anomalies is considered acceptable, and these factors apply to all manufacturers using LCD technology—not just Apple products.
