1 Working on your computer Topics: • Safety instructions 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.
NOTE: If you are using a different operating system, see the documentation of your operating system for shut-down instructions. 3. Disconnect your computer and all attached devices from their electrical outlets. 4. Disconnect all attached network devices and peripherals, such as keyboard, mouse, and monitor from your computer. 5. Remove any media card and optical disc from your computer, if applicable. 6.
the damage. The weakened trace may take weeks or months to melt, and in the meantime may cause degradation of memory integrity, intermittent memory errors, etc. The more difficult type of damage to recognize and troubleshoot is the intermittent (also called latent or "walking wounded") failure. 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.
ESD protection summary It is recommended that all field service technicians use the traditional wired ESD grounding wrist strap and protective anti-static mat at all times when servicing Dell products. In addition, it is critical that technicians keep sensitive parts separate from all insulator parts while performing service and that they use anti-static bags for transporting sensitive components.
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.
● An additional physical bus that is added in parallel with the existing USB 2.0 bus (refer to the picture below). ● 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.
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.
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.
