Use system diagnostics
If you experience an issue with the system, run the system diagnostics before contacting Dell for technical assistance. The
purpose of running system diagnostics is to test the system hardware without using additional equipment or risking data loss.
If you are unable to fix the issue yourself, service and support personnel can use the diagnostics results to help you solve the
issue.
