Diagnostics
If you experience a problem with your computer, run the ePSA diagnostics before contacting Dell for technical
assistance. The purpose of running diagnostics is to test your computer's hardware without requiring 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.
NOTE: Before proceeding download and install the latest BIOS version from support.dell.com
