How to clean your Mighty Mouse


f your Mighty Mouse is covered in fingerprints or its surface has become soiled, it can be gently wiped with a clean lint-free cloth. If necessary, moisten the cloth using only water, making sure not to over saturate it. Be aware that the mouse contains electronic components that may be damaged if water drips from the cloth into the mouse via the seam around the scroll ball or around its underside.

The same procedure can be used to clean the scroll ball on your Mighty Mouse if it has become discolored or dirty. Use a clean lint-free cloth lightly moistened with water. Wipe the ball and the surrounding area, making sure to rotate the ball itself to ensure complete coverage. If the scrolling feels rough or if the scroll ball isn't scrolling up, down, or side-to-side, hold the mouse upside-down and roll the ball vigorously while cleaning it to help dislodge any particles that may have collected on the internal hardware.

MacBook Pro: Distorted video or no video issues


n July 2008, NVIDIA publicly acknowledged a higher than normal failure rate for some of their graphics processors due to a packaging defect. At that same time, NVIDIA assured Apple that Mac computers with these graphics processors were not affected. However, after an Apple-led investigation, Apple has determined that some MacBook Pro computers with the NVIDIA GeForce 8600M GT graphics processor may be affected. If the NVIDIA graphics processor in your MacBook Pro has failed, or fails within two years of the original date of purchase, a repair will be done free of charge, even if your MacBook Pro is out of warranty.

What to look for:

  1. Distorted or scrambled video on the computer screen
  2. No video on the computer screen (or external display) even though the computer is on

Specific products affected:

  1. MacBook Pro 15-inch and 17-inch models with NVIDIA GeForce 8600M GT graphics processors
  2. MacBook Pro (17-Inch, 2.4GHz)
  3. MacBook Pro (15-Inch, 2.4/2.2GHz)
  4. MacBook Pro (Early 2008)
  5. These computers were manufactured between approximately May 2007 and September 2008

If your MacBook Pro is exhibiting any of the symptoms listed above, please take it to an Apple Retail Store or an Apple Authorized Service Provider (AASP) for evaluation, or call your local Apple Contact Center. Before visiting the Genius Bar at the Apple Retail Store, please make a reservation.

Apple is issuing refunds to customers who may have paid for repairs related to this issue. Please contact Apple for details on the refund process.

Note: If your MacBook Pro is not experiencing any of these symptoms, you do not need to contact Apple.

Apple Portables: Tips for maximizing your battery charge

You can take some easy steps to prolong the charge of your Apple portable's battery.

Here are some simple settings and steps you can take to get the most out of your MacBook, MacBook Pro, MacBook Air, iBook or PowerBook battery.

Optimize your battery settings in Energy Saver preferences

  1. From the Apple menu, choose System Preferences.
  2. From the View menu, choose Energy Saver.
  3. Click Show Details.
  4. Choose Battery or Battery Power from the "Settings for" pop-up menu.
  5. Choose Longest or Better Battery Life from the Optimize Energy Settings pop-up menu.

These settings will put the hard disk to sleep whenever possible and reduce the computer's microprocessor performance in order to maximize its battery life. If you are using processor-intensive applications, you may wish to change these settings so the microprocessor performance is no longer reduced.

Set your screen brightness to the lowest comfortable level

Press the F1 (dimmer) and F2 (brighter) keys to dim the screen until the brightness is as low as possible and the screen is still comfortable to look at.

Turn off unused features and technologies.

Just as you would turn off the lights in an unoccupied room, turning off unused features and technologies can help maximize your battery life, too. Here are a few suggestions:

  1. Eject CDs and DVDs you're no longer using. Every so often, the optical drive spins up to read CDs or DVDs. This consumes a small amount of power.
  2. Disconnect peripherals when you're not using them. Connected peripherals, such as printers and digital cameras, can draw power from your battery even when you're not using them.
  3. Shut down any runaway applications.

If you're not in a location where you need to use AirPort or Bluetooth, you can turn them off to save power.

To turn off AirPort:

  1. From the Apple menu, choose System Preferences.
  2. From the View menu, choose Network.
  3. From the Show selection, choose Network Port Configuration.
  4. Uncheck Airport from the list.
  5. Click Apply Now.

To turn off Bluetooth in Mac OS X 10.2 or later:

  1. From the Apple menu, choose System Preferences.
  2. From the View menu, choose Bluetooth.
  3. Click the Settings tab.
  4. Click Turn Bluetooth Off.

Calibrating your computer's battery for best performance

You can calibrate your iBook, PowerBook, MacBook, MacBook Air, or MacBook Pro computer's lithium ion battery for best performance.

The battery has an internal microprocessor that provides an estimate of the amount of energy in the battery as it charges and discharges. The battery needs to be recalibrated from time to time to keep the onscreen battery time and percent display accurate. With all iBooks and PowerBook G4 computers except the aluminum PowerBook G4 (15-inch Double-Layer SD), you should perform this procedure when you first use your computer and then every few months thereafter.


Runaway applications can shorten battery runtime

Battery runtimes can be reduced if an application(s) has run away or taken over system processes. This can cause the processor to work overtime and consume unnecessary battery power.

  1. Open the Activity Monitor (Applications/Utilities).
  2. Select the CPU tab as shown below.

  3. Select All Processes in the pop-up menu:

  4. Select the "% CPU" column:

  5. Look for any application that has taken over the CPU:

  6. If any process is taking more than 70% of the CPU, as shown above, verify if the process is needed. If not, quit the process by selecting the process and clicking the Quit button in the upper left corner of the window to regain CPU process control. This can lead to longer battery runtime.

Exchange files between InCopy and InDesign


hen you work with multiple applications in a single workflow, it is advisable to standardize on a single file format so that you can exchange files between the applications. In a workflow with multiple versions of Adobe InCopy and Adobe InDesign, the Interchange (.incx) format is often the most appropriate format since both InDesign and InCopy can use it. This document explains how to export stories in Interchange (.incx) format from InCopy CS3, InDesign CS3, InDesign CS2, and InCopy CS2 so that content can be exchanged between them.
