1 Working on your computer Topics: • • • Safety precautions Before working inside your computer After working inside your computer Safety precautions The safety precautions chapter details the primary steps to be taken before performing any disassembly instructions. Observe the following safety precautions before you perform any installation or break/fix procedures involving disassembly or reassembly: ● ● ● ● ● ● Turn off the system and all attached peripherals.
● Intermittent – Intermittent failures represent approximately 80 percent of ESD-related failures. The high rate of intermittent failures means that most of the time when damage occurs, it is not immediately recognizable. The DIMM receives a static shock, but the tracing is merely weakened and does not immediately produce outward symptoms related to 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.
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.

3 Technology and components This chapter details the technology and components available in the system. Topics: • • • • • DDR4 HDMI 1.4 USB features USB Type-C Thunderbolt over USB Type-C DDR4 DDR4 (double data rate fourth generation) memory is a higher-speed successor to the DDR2 and DDR3 technologies and allows up to 512 GB in capacity, compared to the DDR3's maximum of 128 GB per DIMM.
Figure 2. Thickness difference Curved edge DDR4 modules feature a curved edge to help with insertion and alleviate stress on the PCB during memory installation. Figure 3. Curved edge Memory Errors Memory errors on the system display the new ON-FLASH-FLASH or ON-FLASH-ON failure code. If all memory fails, the LCD does not turn on.
● 4K Support - Enables video resolutions far beyond 1080p, supporting next-generation displays that will rival the Digital Cinema systems used in many commercial movie theaters ● HDMI Micro Connector - A new, smaller connector for phones and other portable devices, supporting video resolutions up to 1080p ● 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
Speed USB mode, commonly known as USB 2.0 and 1.1 respectively, the slower modes still operate at 480 Mbps and 12 Mbps respectively and are kept to maintain backward compatibility. USB 3.0/USB 3.1 Gen 1 achieves the much higher performance by the technical changes below: ● 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.
contacts in the exact same location as before. Five new connections to carry receive and transmitted data independently are present on USB 3.0/USB 3.1 Gen 1 cables and only come into contact when connected to a proper SuperSpeed USB connection. USB Type-C USB Type-C is a new, tiny physical connector. The connector itself can support various exciting new USB standard like USB 3.1 and USB power delivery (USB PD). Alternate Mode USB Type-C is a new connector standard that's very small.
1. Thunderbolt 1 and Thunderbolt 2 (using a miniDP connector) 2. Thunderbolt 3 (using a USB Type-C connector) 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.
