Apple PowerBook (5300 Series) - Manual (Page 171)

Checking to see the card is properly installed
Once you have completed the process for installing a RAM expansion card,
you can check to make sure the additional RAM is now available on your
computer. Follow these steps:
1 Press the Power key to turn your computer on.
2 Choose About This Macintosh from the Apple ( K ) menu.
3 Look at the number of the total memory in your computer.
Your total memory should be the built-in memory plus the amount of
memory in the RAM expansion card that you just installed.
If the total memory number does not include the amount of RAM you
installed, review the steps in this appendix to make sure you installed the
card correctly. If you need more help, see an Apple-authorized dealer.
If you hear eight tones when the computer starts up, there may be a problem
with the RAM expansion card. If you installed the RAM expansion card in
your computer yourself, review the steps in this appendix to make sure you
installed the card correctly. If you purchased an expansion card from a third-
party manufacturer, contact the manufacturer for help.
