5 Troubleshooting Topics: • • • • • Power supply unit Built-in Self Test Enhanced Pre-Boot System Assessment — ePSA diagnostics Diagnostics Diagnostic error messages System error messages Power supply unit Built-in Self Test Precision 3630 supports a new power supply unit Built-in Self Test (BIST). You can test the health of the power system by pressing the test button or by connecting the power cord. When the power cord is connected, the self-test LED is lit for 3-5 seconds indicating PSU functionality.
CAUTION: Ensure that you take adequate safety precautions before accessing the components on your computer. See the removing and replacing instructions in the service manual for procedure to access the power-supply unit and its cables. 2. Disconnect the power supply unit cables from the system board and other components. 3. Press the PSU BIST button. ● If the LED turns on and remains on while the BIST button is pressed, it indicates that the power-supply unit is functional.
NOTE: To determine the device that is failing, see the light patterns . Off – System is in hibernation or turned off. The power status light blinks amber along with beep codes indicating failures. For example, the power status light blinks amber two times followed by a pause, and then blinks white three times followed by a pause. This 2,3 pattern continues until the computer is turned off indicating the Recovery image is not found.
