The mouse or pointing device
does not work. 1. Verify that the mouse or pointing-device cable is securely connected and the
device drivers are installed correctly.
2. Try using another mouse or pointing device.
If the problem remains, call for service.
Memory problems Verify that:
1. The memory modules are seated properly.
2. You have installed the correct type of memory.
3. If you changed the memory, you updated the memory configuration with the
Configuration/Setup Utility program.
4. All banks of memory on the DIMMs are enabled. The server might have
automatically disabled a DIMM bank when it detected a problem, or a DIMM bank
could have been manually disabled.
Look in the POST error log for error message 289:
• If the DIMM was disabled by a system-management interrupt (SMI), replace the
DIMM.
• If the DIMM was disabled by the user or by POST:
1. Start the Configuration/Setup Utility program.
2. Enable the DIMM.
3. Save the configuration and restart the server.
• If you continue to get this error, replace the DIMM.
If the problem persists, call for service.
The amount of system memory
displayed is less than the
amount of physical memory
installed.
Microprocessor problems The startup (boot) microprocessor is not working properly.
Verify that the startup microprocessor is seated properly. If it is, replace the startup
microprocessor.
If the problem remains, call for service.
The server emits a continuous
tone during POST.
Monitor problems Some IBM monitors have their own self-tests. If you suspect a problem with your
monitor, see the information that comes with the monitor for adjusting and testing
instructions.
If you still cannot find the problem, call for service.
Testing the monitor.
The screen is blank. Verify that:
1. The server power cord is plugged into the server and a working electrical outlet.
2. The monitor cables are connected properly.
3. The monitor is turned on and the Brightness and Contrast controls are adjusted
correctly.
Important: In some memory configurations, the 3-3-3 beep code might sound during
POST followed by a blank display screen. If this occurs and the Boot Fail Count
feature in the Start Options of the Configuration/Setup Utility program is set to
Enabled (its default setting), you must restart the server three times to force the
system BIOS to reset the CMOS values to the default configuration (memory
connector or bank of connectors Enabled).
If the items above are correct and the screen remains blank, call for service.
Only the cursor appears. Call for service.
