Problems” on page 24 and run the Dell Diagnostics
before you contact Dell for technical assistance.
It is recommended that you print these procedures
before you begin.
See the System Setup section in the “Service
Manual” to review your computer’s configuration
information, and to ensure that the device you want to
test displays in the system setup program and is active.
Start the
