Q) Sometimes when I startup my PowerBook, the startup sound plays twice. Why?
A) On PowerBooks that can switch from normal processor speed to 16MHz, CPU switches the processor speed automatically at sleep or restart depending upon whether or not the AC charger is plugged in. On most PowerBooks, you must restart to make the change in clock speed. At boot, CPU checks to see if the charger is connected, sets the PowerBook to boot at the desired clock speed (full speed when the charger is plugged in, 16MHz if not) and restarts the PowerBook if necessary. This is why the PowerBook startup sound is heard twice. Since PowerBook Duos are capable of dynamically switching clock speed, the "stutter-start" never occurs on these computers.
Q) Why doesn't the caps lock key work?
A) CPU allows you to modify the behavior of the caps lock key on the PowerBook's built-in keyboard. You can change caps lock so that it activates only if the shift or control key is held down, or disable caps lock altogether. You can configure this feature in the Extended Keys panel.
Q) Why does only one application show its windows at a time?
A) In order to help you avoid a cluttered desktop, CPU's AppManager can automatically hide an application's windows when it is in the background. If you want to temporarily see all of your applications' windows, select "Show All" from the System 7 Application Menu. You can turn this feature off by unchecking "Hide Background Apps" in QuickConfigure mode or by unchecking "Hide Background Applications" in the AppManager panel in FineTune mode.
