Apple Macintosh PowerBook 1400 - Manual (Page 92)

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 some of the system software extensions from the Extensions
folder (inside the System Folder).
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 your current documents will be
lost.) Immediately save all open documents, quit all other open programs,
and restart the computer.
m Press the reset button 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,” in the section “Problems Starting
Up the Computer” earlier in this chapter.) If the problem still occurs, see
Chapter 7.
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
feature to search for the desktop file. It may find it but you may not be able
to access it.)
