Note: See "System" on page 162 to determine which components should be replaced by a field service technician. Software problem Symptom FRU/action Suspected software problem. 1. To determine if problems are caused by the software, verify that: v The computer has the minimum memory needed to use the software. For memory requirements, see the information that comes with the software. Note: If you have just installed an adapter or memory, you might have a memory address conflict. v The software is designed to operate on the computer. v Other software works on the computer. v The software that you are using works on another system. If you received any error messages when using the software program, see the information that comes with the software for a description of the messages and suggested solutions to the problem. 2. If you have verified these items and the problem remains, contact your place of purchase. Note: See "System" on page 162 to determine which components should be replaced by a field service technician. Universal Serial Bus (USB) port problems Symptom FRU/action A USB device does not work. v Verify that: - You are not trying to use a USB device during POST if you have a standard (non-USB) keyboard attached to the keyboard port. Note: If a standard (non-USB) keyboard is attached to the keyboard port, the USB is disabled and no USB device will work during POST. - The correct USB device driver is installed. - The operating system supports USB devices. Power-supply LED errors Use the information in this section to solve power-supply problems. Note: The minimum configuration required for the dc good light to be lit is: v Power supply v Power cage assembly, if installed. v System board (set switch 7 of SW1 to bypass the power switch; see "System-board switches and jumpers" on page 51.
