1 Working on your computer Safety instructions Prerequisites Use the following safety guidelines to protect your computer from potential damage and to ensure your personal safety. Unless otherwise noted, each procedure included in this document assumes that the following conditions exist: • • You have read the safety information that shipped with your computer. A component can be replaced or, if purchased separately, installed by performing the removal procedure in reverse order.
Steps 1. Ensure that you follow the Safety Instruction. 2. Ensure that your work surface is flat and clean to prevent the computer cover from being scratched. 3. Turn off your computer. 4. Disconnect all network cables from the computer. CAUTION: To disconnect a network cable, first unplug the cable from your computer and then unplug the cable from the network device. 5. Disconnect your computer and all attached devices from their electrical outlets. 6.
Perform the following steps to prevent ESD damage: • • • • Use a wired ESD wrist strap that is properly grounded. The use of wireless anti-static straps is no longer allowed; they do not provide adequate protection. Touching the chassis before handling parts does not ensure adequate ESD protection on parts with increased sensitivity to ESD damage. Handle all static-sensitive components in a static-safe area. If possible, use anti-static floor pads and workbench pads.
Transporting sensitive components When transporting ESD sensitive components such as replacement parts or parts to be returned to Dell, it is critical to place these parts in anti-static bags for safe transport. Lifting equipment Adhere to the following guidelines when lifting heavy weight equipment: CAUTION: Do not lift greater than 50 pounds. Always obtain additional resources or use a mechanical lifting device. 1. 2. 3. 4. 5. Get a firm balanced footing.
2 Technology and components This chapter details the technology and components available in the system. Topics: • • • • USB features USB Type-C HDMI 1.4a Power button LED behavior USB features Universal Serial Bus, or USB, was introduced in 1996. It dramatically simplified the connection between host computers and peripheral devices like mice, keyboards, external drivers, and printers. Table 1. USB evolution Type Data Transfer Rate Category Introduction Year USB 2.
• • USB 2.0 previously had four wires (power, ground, and a pair for differential data); USB 3.0/USB 3.1 Gen 1 adds four more for two pairs of differential signals (receive and transmit) for a combined total of eight connections in the connectors and cabling. USB 3.0/USB 3.1 Gen 1 utilizes the bidirectional data interface, rather than USB 2.0's half-duplex arrangement. This gives a 10-fold increase in theoretical bandwidth.
Alternate Mode USB Type-C is a new connector standard that is very small. It is about a third the size of an old USB Type-A plug. This is a single connector standard that every device should be able to use.
3. DisplayPort 1.4 – compatible with existing DisplayPort monitors, devices and cables 4. USB Power Delivery - Up to 130W on supported computers Key Features of Thunderbolt 3 over USB Type-C 1. 2. 3. 4. 5.
• HDMI supports communication between the video source (such as a DVD player) and the DTV, enabling new functionality. Power button LED behavior On certain Dell Latitude systems, the power button LED is used to provide an indication of the system status, and as a result the power button illuminates when pressed.
Power button with fingerprint reader will have no LED and will leverage the available LED's in the system to provide indication of the system status • Power Adapter LED: • • The LED on Power adapter connector illuminates white when power is supplied from electrical outlet. Battery Indicator LED: • If the computer is connected to an electrical outlet, the battery light operates as follows: • 1. Solid white -the battery is charging. When the charge is complete the LED turns off.

5 Troubleshooting Enhanced Pre-Boot System Assessment (ePSA) diagnostics About this task The ePSA diagnostics (also known as system diagnostics) performs a complete check of your hardware. The ePSA is embedded with the BIOS and is launched by the BIOS internally.
The power and battery-status light blinks amber along with beep codes indicating failures. For example, the power and battery-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 no memory or RAM is detected.
