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