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.

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.

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.

Check the system and power connections to the monitor.

Check the video interface cabling from the system to the monitor.

Run the appropriate diagnostic test.

If the tests run successfully, the problem is not related to video hardware.

If the tests fail, see the Getting help section.

Prerequisites

NOTE: Follow steps 1 to 6 to troubleshoot a USB keyboard or mouse. For other USB devices, go to step 7.

NOTE: The sled has a single USB port that can be expanded by using a USB hub.

Steps

Disconnect the keyboard and/or mouse cables from the system and reconnect them.

If the problem persists, connect the keyboard and/or mouse to another USB port on the system.

If the problem is resolved, restart the system, enter System Setup, and check if the non-functioning USB ports are enabled.

NOTE: Older operating systems may not support USB 3.0.

Check if USB 3.0 is enabled in System Setup. If enabled, disable it and see if the issue is resolved.
