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 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.
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 After you complete any replacement procedure, ensure that you connect any external devices, cards, and cables before turning on your computer. 1.

3 Technology and components 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 evolution Type Data Transfer Rate Category Introduction Year USB 2.0 480 Mbps High Speed 2000 USB 3.0/USB 3.1 Gen 1 5 Gbps Super Speed 2010 USB 3.
With today's ever increasing demands placed on data transfers with high-definition video content, terabyte storage devices, high megapixel count digital cameras etc., USB 2.0 may not be fast enough. Furthermore, no USB 2.0 connection could ever come close to the 480Mbps theoretical maximum throughput, making data transfer at around 320Mbps (40MB/s) — the actual real-world maximum. Similarly, USB 3.0/USB 3.1 Gen 1 connections will never achieve 4.8Gbps.
DDR4 needs 20 percent less or just 1.2 volts, compared to DDR3 which requires 1.5 volts of electrical power to operate. DDR4 also supports a new, deep power-down mode that allows the host device to go into standby without needing to refresh its memory. Deep power-down mode is expected to reduce standby power consumption by 40 to 50 percent. DDR4 Details There are subtle differences between DDR3 and DDR4 memory modules, as listed below.
Processor NOTE: Processor numbers are not a measure of performance. Processor availability is subject to change and may vary by region/country. Table 2.
