Safety instructions
Use the following safety guidelines to protect your computer from potential damage and ensure your personal safety.
NOTE:
Before working inside your computer, read the safety information that shipped with your computer. For more safety
best practices, see the Regulatory Compliance home page at www.dell.com/regulatory_compliance.
NOTE: Disconnect all power sources before opening the computer cover or panels. After you finish working inside the
computer, replace all covers, panels, and screws before connecting to the electrical outlet.
CAUTION: To avoid damaging the computer, ensure that the work surface is flat and clean.
CAUTION: To avoid damaging the components and cards, handle them by their edges, and avoid touching pins
and contacts.
CAUTION: You should only perform troubleshooting and repairs as authorized or directed by the Dell technical
assistance team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. See the
safety instructions that shipped with the product or at www.dell.com/regulatory_compliance.
CAUTION: Before touching anything inside your computer, ground yourself by touching an unpainted metal
surface, such as the metal at the back of the computer. While you work, periodically touch an unpainted metal
surface to dissipate static electricity, which could harm internal components.
CAUTION: When you disconnect a cable, pull on its connector or on its pull tab, not on the cable itself. Some
cables have connectors with locking tabs or thumb-screws that you must disengage before disconnecting the

Diagnostics
Power status light: Indicates the power status.
Solid Amber – The computer is unable to boot to the operating system. This indicates that the power supply or another device
in the computer is failing.
Blinking Amber – The computer is unable to boot to the operating system. This indicates that the power supply is normal but
another device in the computer is failing or not installed properly.
NOTE: See the light patterns to determine the device that is failing.
Off – Computer is in hibernation or turned off.
The power status light blinks amber along with beep codes indicating failures.
For example, the power status light blinks amber two times followed by a pause, and then blinks white three times followed by a
pause. This 2,3 pattern continues until the computer is turned off indicating the Recovery image is not found.
The following table shows different light patterns and what they indicate:
Table 13. System diagnostic lights
Light pattern Problem description
1 System board, BIOS corruption, or ROM error
3 System board, Chipset error, Clock failure, Gate A20 failure, Super I/O
failure, or Keyboard controller failure
4 Memory or RAM failure
5 Coin-cell battery failure
6 GPU failure
7 CPU failure
8 Display failure
3,6 BIOS recovery image not found
3,7 BIOS recovery image found but invalid
The computer may emit a series of beeps during start-up if the errors or problems cannot be displayed. The repetitive beep
codes help the user troubleshoot problems with the computer.
Camera status light: Indicates whether the camera is in use.
● Solid white – Camera is in use.
