1 Working on your computer Topics: • • • • Safety precautions Before working inside your computer Turning off 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. Before working inside your computer 1.
After working inside your computer After you complete any replacement procedure, ensure that you connect external devices, cards, and cables before turning on your computer.

3 Technology and components This chapter details the technology and components available in the system. Topics: • • USB features HDMI 1.4 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 2. 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.
Thunderbolt over USB Type-C Thunderbolt is a hardware interface that combines data, video, audio, and power in a single connection. Thunderbolt combines PCI Express (PCIe) and DisplayPort (DP) into one serial signal, and additionally provides DC power, all in one cable. Thunderbolt 1 and Thunderbolt 2 use the same connector [1] as miniDP (DisplayPort) to connect to peripherals, while Thunderbolt 3 uses a USB Type-C connector [2]. Figure 1. Thunderbolt 1 and Thunderbolt 3 1.
● Reversible plug orientation and cable direction ● Backwards compatibility to VGA, DVI with adaptors ● Supports HDMI 2.0a and is backwards compatible with previous versions HDMI 1.4 This topic explains the HDMI 1.4 and its features along with the advantages. HDMI (High-Definition Multimedia Interface) is an industry-supported, uncompressed, all-digital audio/video interface.
4 Software This chapter details the supported operating systems along with instructions on how to install the drivers. Topics: • • Supported operating systems Downloading Windows drivers Supported operating systems Table 4.
Chipset driver The chipset driver helps the system identify the components and install necessary drivers accurately. Verify that the chipset was installed in the system by checking the below controllers. Many of the common devices are visible under Other Devices if no drivers are installed. The unknown devices disappear once you install the chipset driver. Make sure to install the following drivers, some of them may exist by default.
Management Engine Interface drivers Serial IO driver Verify if the drivers for Touchpad, IR camera, and keyboard and are installed. Figure 2.
