Modem problems
Memory problems Action
The amount of memory
displayed is less than the
amount of memory
installed. The amount of available memory shown might be
somewhat less than expected because of basic
input/output system (BIOS) shadowing and other
resource requirements (such as ACPI and USB).
Verify that:
1. You have installed the correct type of DIMMs for
your computer. See “Working with memory” on
page 66 for instructions on adding DIMMs.
2. The DIMMs are properly installed and securely
connected.
3. If you added or removed memory, you saved the
new configuration before exiting the
Configuration/Setup Utility program.
If the problem persists, run the memory test from the
diagnostic program supplied with your computer. (See
“IBM Diagnostic Programs” on page 123 for further
information.) The system might have detected a bad
DIMM and automatically reallocated memory to enable
your computer to continue to operate.
If you cannot correct the problem, have the computer
serviced.
Modem problems Action
When you try to use the
modem, your computer
or modem is unable to
detect a dial tone. 1. Make sure the telephone line is correctly connected
to your computer. Connections for a standard
modem are shown in Chapter 8, “Installing external
options” on page 87. If you are using other
communication devices in conjunction with the
modem, such as an ADSL adapter or home
networking adapter, refer to the documentation for
those devices to ensure the cords are properly
connected.
2. Make sure no one is using the telephone.
3. Make sure the telephone line is working.
4. Add the modem command x3 to the initialization
string for the communications program you are
using. For help with changing the initialization
string, refer to the documentation that came with
your communications program.
