POST Message Description
20X A failure occurred during testing of the memory. This error can be caused by incorrectly installed memory,
a failing memory-module kit, or a system-board failure.
Action:
1. If you just installed memory, see Installing Options in Your Personal Computer to verify that the new
memory is correct for your system unit, that it is installed correctly, and that the memory-module
configuration matches one of the configurations shown in the system memory table.
2. Run the diagnostic tests to verify the problem.
3. If the system diagnostic tests detect a failure, have the computer serviced.
229 An external cache error occurred.
Action: Have the computer serviced.
301
303 A failure occurred during testing of the keyboard and keyboard controller. These error messages also might
be accompanied by continuous beeping.
Action:
Ensure that:
1. Nothing is resting on the keyboard and pressing a key
2. No key is stuck
3. The keyboard cable is connected correctly to the keyboard and to the correct connector on the computer.
Running the diagnostic tests can isolate the computer component that failed, but you must have your
computer serviced.
Note: If you have just connected a new mouse or other pointing device, turn the computer off and
disconnect that device. Wait at least 5 seconds, and then turn the computer on. If the error message
goes away, replace the device.
If the error message remains, have the keyboard and cable or the computer serviced.
601 A failure occurred during testing of the diskette drive and diskette-drive controller. This error can be
caused by a loose or incorrectly connected cable, a failing drive, or a failing system board.
Action: The computer can be used, but one or more diskette drives might not work. Running the
diagnostic tests can isolate the diskette drive that failed, but you must have your computer serviced.
