1 Working on your computer Topics: • Safety instructions Safety instructions 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.
6. After the computer is unplugged, press and hold the power button for 5 seconds to ground the system board. CAUTION: Place the computer on a flat, soft, and clean surface to avoid scratches on the display. 7. Place the computer face down. Safety precautions The safety precautions chapter details the primary steps to be taken before performing any disassembly instructions.
● 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 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 2.0 480 Mbps High Speed 2000 USB 3.0/USB 3.
● 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.
USB Type-C USB Type-C is a new, tiny physical connector. The connector itself can support various exciting new USB standards like USB 3.1 and USB power delivery (USB PD). 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.
Thunderbolt 3 over USB Type-C Thunderbolt 3 brings Thunderbolt to USB Type-C at speeds up to 40 Gbps, creating one compact port that does it all delivering the fastest, most versatile connection to any dock, display or data device like an external hard drive. Thunderbolt 3 uses a USB Type-C connector/port to connect to supported peripherals. 1. 2. 3. 4. Thunderbolt 3 uses USB Type-C connector and cables - It is compact and reversible Thunderbolt 3 supports speed up to 40 Gbps DisplayPort 1.
● Automotive Connection System - New cables and connectors for automotive video systems, designed to meet the unique demands of the motoring environment while delivering true HD quality. Advantages of HDMI ● Quality HDMI transfers uncompressed digital audio and video for the highest, crispest image quality. ● Low-cost HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a simple, cost-effective manner.
