Apple Macintosh PowerBook 180 computers - Manual (Page 280)

A window has disappeared.
n
Another open window on the desktop may have covered the
window you’re looking for. Move, resize, close, or hide
windows you aren’t using until you see the one you want.
n
Windows belonging to open but inactive programs may be
hidden. Choose Show All from the Application menu to show
hidden windows.
An icon is blinking in the menu bar.
n
One of your programs needs your attention. For example, you
may have set the Alarm Clock to go off at a particular time, or
PrintMonitor may be alerting you to a printing problem. Make
the program active and take the necessary action.
Memory
A “not enough memory” message appears when you try to
open a program.
n
Quit any programs you aren’t using, then try again to open
the program you want. If that doesn’t work, restart the
computer. Sometimes restarting makes additional memory
available.
n
If you are using a RAM disk or a disk cache, reduce its size and
then restart the computer.
n
Use extra space on your hard disk as virtual memory to
increase the amount of memory available for opening
programs. (Use virtual memory only when the power adapter
is plugged in.)
n
If you consistently want to open more programs than memory
allows, you can purchase a memory expansion card from your
authorized Apple dealer.
SCSI devices
You can’t turn on the computer after connecting a
SCSI device.
n
SCSI devices connected to your computer must be turned on
before the computer itself. Turn on the SCSI device(s) first,
and then turn on the computer.
