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 NOTE: Instructions provided in this section are applicable on computers shipped with Windows 10 operating system. Windows 10 is factory-installed with this computer. Topics: • • • • DDR4 HDMI 1.4 USB features 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.
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. 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.
• HDMI supports communication between the video source (such as a DVD player) and the DTV, enabling new functionality 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.
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.
• 7th Generation or higher Intel Core i3/i5/i7 processor • Windows 10 64-bit version or higher • Intel Rapid Storage Technology driver version 15.9.1.1018 or higher Table 2.

4 Troubleshooting Enhanced Pre-Boot System Assessment (ePSA) diagnostics About this task CAUTION: Use the ePSA diagnostics to test only your computer. Using this program with other computers may cause invalid results or error messages. The ePSA diagnostics (also known as system diagnostics) performs a complete check of your hardware. The ePSA is embedded with the BIOS and is launched by the BIOS internally.
• • Computer is running on battery and the battery has more than 5 percent charge. Computer is in sleep state, hibernation, or turned off. The power and battery-status light blinks amber along with beep codes indicating failures. For example, the power and battery-status light blinks amber two times followed by a pause, and then blinks white three times followed by a pause.
