Apple Macintosh PowerBook 190 Series - Manual (Page 95)

When the computer starts up, a message says there is not enough memory.
m There may not be enough memory to load all the system software
extensions you’ve installed. Restart the computer, holding down the Shift
key until you see the message “Extensions off” in the Welcome to
Macintosh box. Then try the following to increase available memory:
m Reduce the size of the disk cache in the Memory control panel.
m If you use a RAM disk, reduce its size or turn it off in the Memory
control panel.
m Remove any system software extensions you don’t need from the
Extensions folder (inside the System Folder).
m Turn on virtual memory in the Memory control panel.
You need to restart the computer for these changes to take effect.
m If these suggestions don’t work, you can increase memory by installing a
RAM expansion card in your computer. See Appendix C for information.
The computer won’t restart.
m If the computer freezes, you can try to “force” the program you’re using to
quit by simultaneously pressing the keys Command (x), Option, and Esc
on your keyboard. Then click Force Quit in the dialog box that appears.
(Note: Unsaved changes in any open documents will be lost.) Immediately
save all open documents, quit all other open programs, and restart the
computer.
m Press the reset button (marked with the icon I) on the back panel.
Note: You will lose any work you have not saved.
m If the problem recurs, reset the parameter RAM (see “The Computer
Makes an Unusual Sound at Startup,” earlier in this section). If the problem
still occurs, see Chapter 8, “Diagnostic Techniques.”
Every time the computer starts up, it rebuilds the desktop.
m There may be a folder on your hard disk that has the same name as a file
the computer uses to keep track of information on your disks. Manually
search for a folder named “Desktop” or “Desktop file.” If you find one,
rename it “Storage.” Then restart the computer. (Do not use the Find File
command to search for the desktop file. It may find it but you may not be
able to access it.)
