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 your system halts during startup prior to video imaging or LCD messaging,

especially after installing an operating system or reconfiguring your system’s

hardware, check for the following conditions.

• If you boot the system to the BIOS boot mode after installing an operating

system from the UEFI Boot Manager, the system will hang. The reverse is

also true. You must boot to the same boot mode in which you installed the

operating system. See "Using the System Setup Program and UEFI Boot

Manager."

• Invalid memory configurations could cause the system to halt at startup

without any video output. See "System Memory."

For all other startup issues, note the LCD panel messages and any system

messages that appear onscreen. See "LCD Status Messages" and "System

Messages" for more information.

Troubleshooting External Connections

Ensure that all external cables are securely attached to the external

connectors on your system before troubleshooting any external devices. See

Figure 1-1 and Figure 1-4 for the front- and back-panel connectors on your

system.
