1 Working on your computer 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. A component can be replaced or, if purchased separately, installed by performing the removal procedure in reverse order.
6. Press and hold the power button while the computer is unplugged to ground the system board. NOTE: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal surface at the same time as touching a connector on the back of the computer. Safety precautions The safety precautions chapter details the primary steps to be taken before performing any disassembly instructions.
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.
4. Keep the load close. The closer it is to your spine, the less force it exerts on your back. 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 About this task After you complete any replacement procedure, ensure that you connect any external devices, cards, and cables before turning on your computer.
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. Let's take a quick look on the USB evolution referencing to the table below. Table 1.
• • 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.
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.
3. DisplayPort 1.4 – compatible with existing DisplayPort monitors, devices and cables 4. USB Power Delivery - Up to 130W on supported computers Key Features of Thunderbolt 3 over USB Type-C 1. 2. 3. 4. 5.
• • HDMI combines video and multichannel audio into a single cable, eliminating the cost, complexity, and confusion of multiple cables currently used in A/V systems HDMI supports communication between the video source (such as a DVD player) and the DTV, enabling new functionality Power button LED behavior On certain Dell Latitude systems, the power button LED is used to provide an indication of the system status, and as a result the power button illuminates when pressed.
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.
