POST Message 162 Description A change in device configuration occurred. This message is displayed under one or more of the following conditions: A new device has been installed. A device has been moved to a different location or cable connection. A device has been removed or disconnected from a cable. A device is failing and is no longer recognized by the computer as being installed. An external device is not turned on. An invalid checksum is detected in CMOS memory (nonvolatile RAM). Action: 1. Verify that all external devices are turned on. External devices must be turned on before the computer is turned on. 2. Verify that all devices are properly installed and securely connected. 3. If you added, removed, or changed the location of a device, you must save the new configuration in the Configuration/Setup Utility program. Refer to the Important text box on page 34 for further information and instructions on saving the configuration. 4. If you added or changed a microprocessor, you must update system programs. Refer to "System Programs" on page 26 for instructions. 5. If you did not add, remove, or change the location of a device, a device is probably failing. Running the diagnostic programs might isolate the failing device. (See "Diagnostic Programs" on page 95 for information about diagnostic programs provided with your computer.) If the problem cannot be isolated and corrected, have the computer serviced. 68 Using Your Personal Computer
