IBM 201 Two short beeps, Three short beeps, Repeating short beeps, One long and one short beep

Two short beeps

POST encountered an error. The Configuration/Setup Utility program will display additional information; follow the instructions that appear on the screen. See “POST error messages” on page 92 for descriptions of the text messages that might appear.

Three short beeps

A system memory error has occurred. This combination occurs only if the video Basic Input/Output System (BIOS) cannot display the error message. Replace the failing memory module.

Repeating short beeps

The system board might contain a failing component, your keyboard might be defective, or a key on the keyboard might be stuck. 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 appliance.

Running the diagnostic tests can isolate the appliance component that failed, but you must have your system serviced. If the error message remains, call for service.

Note: If you just connected a new mouse or other pointing device, turn off the appliance and disconnect that device. Wait at least 5 seconds; then, turn on the appliance. If the error message goes away, replace the device.

One long and one short beep

POST encountered an error on a video adapter. If you are using the integrated video controller, call for service. If you are using an optional video adapter, replace the failing video adapter.

One long and two short beeps

A video I/O adapter ROM is not readable, or the video subsystem is defective. If you hear this beep combination twice, both the system board and an optional video adapter have failed the test. This beep combination might also indicate that the system board contains a failing component.

One long and three short beeps

This series of beeps has two meanings. The first means that the POST has completed without detecting errors, when a monitor and keyboard is not attached. However, when a monitor is attached, and you hear this series, it means the system-board video subsystem has not detected a monitor connection to the appliance. Ensure that the monitor is connected properly to the appliance. If the problem persists, replace the monitor.

Two long and two short beeps

POST does not support the optional video adapter. This beep combination occurs when you install a video adapter that is incompatible with your appliance. Replace the optional video adapter with one that the appliance supports or use the integrated video controller.

Table 15 on page 89 describes the codes and specifies the action to take.
