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 came with the product.

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. 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

Ensure that all external cables are securely attached to the external connectors on your system before troubleshooting any external devices.

Troubleshooting the video subsystem

1.Check the system and power connections to the monitor.

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

3.Run the appropriate diagnostic test.

Troubleshooting a USB device

Use the following steps to troubleshoot a USB keyboard/mouse. For other USB devices, go to step 7.

1.Disconnect the keyboard and mouse cables from the system and reconnect them.

2.If the problem persists, connect the keyboard/mouse to the USB port(s) on the opposite side of the system.

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

Check if USB 3.0 is enabled in System Setup. If enabled, disable it and see if the issue is resolved (older operating systems may not support USB 3.0).
