Troubleshooting your system
Safety first — for you and your system
CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and
simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support
team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety
instructions that are shipped with your product.
NOTE: Solution validation was performed by using the factory shipped hardware configuration.
Troubleshooting system startup failure
If you boot the system to the BIOS boot mode after installing an operating system from the UEFI Boot Manager, the system stops
responding. To avoid this issue, you must boot to the same boot mode in which you installed the operating system.
For all other startup issues, note the system messages that appear on the screen.
Troubleshooting external connections
Before troubleshooting any external devices, ensure that all external cables are securely attached to the external connectors on your
system before troubleshooting any external devices.
Troubleshooting the video subsystem
Prerequisites
NOTE: Ensure the Local Server Video Enabled option is selected in the iDRAC Graphical User Interface (GUI), under
Virtual Console. If this option is not selected, local video is disabled.
Steps
1.
Check the cable connections (power and display) to the monitor.
2.
Check the video interface cabling from the system to the monitor.
3.
Run the appropriate diagnostic test.
If the tests run successfully, the problem is not related to video hardware.
Next steps
If the tests fail, see the Getting help section.
Troubleshooting a USB device
Prerequisites
NOTE: Follow steps 1 to 5 to troubleshoot a USB keyboard or mouse. For other USB devices, go to step 6.
