Apple PowerBook (2400c) - Manual (Page 92)

I can’t access some of the memory on my computer.
m All computers set aside some memory for system overhead.
m If you want to open more programs than memory allows, you can use the
Memory control panel to decrease the size of the disk cache, or remove or
decrease the size of the RAM disk (if you’re using one). You can also have
a memory expansion card installed in your computer.
Problems with hardware
RAM or cache diagnostic error
I see a message that a problem was detected with RAM or cache memory.
m If you see this type of error message, take your computer to an Apple-
authorized service provider as soon as possible. Ignoring this condition
could lead to random errors and failure that could result in your losing
data. (Although the error message may not reappear, the problem detected
during the computer’s self-check probably has not gone away.)
External floppy disk drive
I can’t eject a floppy disk.
m The disk may be stuck. Restart the computer, holding down the button on
your trackpad. If the disk is not ejected, you can eject it manually.
Carefully insert the end of a straightened paper clip into the small hole
near the disk drive’s opening, and push firmly until the disk is ejected.
Insert the end of a
large, straightened
paper clip into
this hole.
