1 Working on your computer Topics: • • • • Safety instructions Turning off your computer — Windows 10 Before working inside your computer After working inside 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.
NOTE: Ensure that the computer and all attached devices are turned off. If your computer and attached devices did not automatically turn off when you shut down your operating system, press and hold the power button for about 6 seconds to turn them off. Before working inside your computer 1. Ensure that your work surface is flat and clean to prevent the computer cover from being scratched. 2. Turn off your computer. 3. Disconnect all network cables from the computer (if available).
2 Technology and components This chapter details the technology and components available in the system. Topics: • • • DDR4 USB features HDMI 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 capacity of 128 GB per DIMM.
Feature/Option DDR3 DDR4 DDR 4 Advantages Multi-Purpose Register Four Registers – 1 Defined, 3 RFU Four Registers – 3 Defined, 1 RFU Provides Additional Specialty Readout DIMM Types RDIMM, LRDIMM, UDIMM, SODIMM RDIMM, LRDIMM, UDIMM, SODIMM DIMM Pins 240 (R, LR, U); 204 (SODIMM) 288 (R, LR, U); 260 (SODIMM) RAS ECC CRC, Parity, Addressability, GDM More RAS features; improved data integrity DDR4 Details There are subtle differences between DDR3 and DDR4 memory modules, as listed below.
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 2. 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 3.1 Gen 2 Super Speed 2013 10 Gbps USB 3.0/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.
HDMI This topic explains the HDMI 1.4/ 2.0 and its features along with the advantages. HDMI (High-Definition Multimedia Interface) is an industry-supported, uncompressed, all-digital audio/video interface. HDMI provides an interface between any compatible digital audio/video source, such as a DVD player, or A/V receiver and a compatible digital audio and/or video monitor, such as a digital TV (DTV). The intended applications for HDMI TVs, and DVD players.
