1 Working on your computer 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.
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. Disconnect the system and all attached peripherals from AC power. Disconnect all network cables, telephone, and telecommunications lines from the system.
ESD field service kit The unmonitored Field Service kit is the most commonly used service kit. Each Field Service kit includes three main components: antistatic mat, wrist strap, and bonding wire. Components of an ESD field service kit The components of an ESD field service kit are: • • • • • • • Anti-Static Mat – The anti-static mat is dissipative and parts can be placed on it during service procedures.
5. Keep your back upright, whether lifting or setting down the load. Do not add the weight of your body to the load. Avoid twisting your body and back. 6. Follow the same techniques in reverse to set the load down. After working inside your computer After you complete any replacement procedure, ensure that you connect any external devices, cards, and cables before turning on your computer. 1. Connect any telephone or network cables to your computer.
2 Technology and components This chapter details the technology and components available in the system. Topics: • • • • • • DDR4 USB features USB Type-C Advantages of DisplayPort over USB Type-C HDMI 2.0 Intel Optane memory 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.
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. Troubleshoot for possible memory failure by trying known good memory modules in the memory connectors on the bottom of the system or under the keyboard, as in some portable systems.
• • • 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.
• • • 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 HDM
