During POST, the computer checks the computer’s memory, and then writes to and
reads from the number of available bytes to ensure proper operation. If the memory
count displayed is less than the amount installed, make a copy of the Diagnostics
Checklist found in Chapter 5 and fill it out as you complete the following procedure:
1. Reboot the computer. Does the random-access memory (RAM) count displayed
correctly match the actual amount of memory installed in the computer?
Yes. The computer needed to update the memory; the memory check phase is
OK now.
No.
Go to step 2.
2. Save all your work, exit any open application programs, and remove any installed
batteries.
3. Turn off the computer and disconnect it from the AC adapter. Then disconnect
the AC adapter from AC power. Turn off any attached peripherals, and disconnect
them from their power sources and then from the computer.
4. Ground yourself by touching one of the metal connectors on the back of the
computer.
5. Turn the computer over and remove the memory module cover as shown in
Figure 3-7.
Slide the memory module cover as far as it will go in the direction of the arrow,
and then lift it away from the computer.
