Memory Module Problems
If you added extra memory to your system by installing SIMMs
and that memory is not operating properly, check the following:
1. If the memory count displayed by the power-on
diagnostics program is incorrect, you or your dealer may
not have installed the SIMMs correctly. The SIMMs may be
installed in the wrong sockets, they may be the wrong type,
or they may not be inserted all the way into their sockets.
If your dealer installed SIMMs for you, contact your dealer;
do not attempt to correct the problem yourself. If you
installed them, see “Adding Memory Modules” in
Chapter 4 and make sure you followed all the instructions.
2. Be sure to run the SETUP program after you install or
remove memory modules to automatically update your
memory configuration. See Chapter 2 of the Setup Guide for
instructions.
3. If you are still having trouble with your SIMMs, write
down any error messages and contact your dealer.
Battery Problems
The battery in your computer is a 3.6 volt, lithium battery. It
should last from three to five years before you need to replace
it. When the battery’s life is exhausted, you may see one of the
following error messages:
CMOS battery state low
CMOS system options not set
Purchase a new battery pack and follow the instructions in
Chapter 4 to install it or have your dealer to install it for you.
