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 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.
CAUTION: If your computer has an RJ45 port, disconnect the network cable by first unplugging the cable from your computer. 5 Disconnect your computer and all attached devices from their electrical outlets. 6 Open the display. 7 Press and hold the power button for few seconds, to ground the system board. CAUTION: To guard against electrical shock unplug your computer from the electrical outlet before performing Step # 8.
2 Technology and components This chapter details the technology and components available in the system. Topics: • HDMI 2.0 • USB features • USB Type-C HDMI 2.0 This topic explains the HDMI 2.0 and its features along with the advantages. HDMI (High-Definition Multimedia Interface) is an industry-supported, uncompressed, all-digital audio/video interface.
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 3.1 Gen 2 10 Gbps Super Speed 2013 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.
Microsoft announced that Windows 7 would have USB 3.1 Gen 1 support, perhaps not on its immediate release, but in a subsequent Service Pack or update. It is not out of the question to think that following a successful release of USB 3.0/USB 3.1 Gen 1 support in Windows 7, SuperSpeed support would trickle down to Vista. Microsoft has confirmed this by stating that most of their partners share the opinion that Vista should also support USB 3.0/USB 3.1 Gen 1.
Figure 1. Thunderbolt 1 and Thunderbolt 3 1 Thunderbolt 1 and Thunderbolt 2 (using a miniDP connector) 2 Thunderbolt 3 (using a USB Type-C connector) Thunderbolt 3 over Type-C Thunderbolt 3 brings Thunderbolt to USB Type-C at speeds up to 40 Gbps, creating one compact port that does it all - delivering the fastest, most versatile connection to any dock, display or data device like an external hard drive. Thunderbolt 3 uses a USB Type-C connector/port to connect to supported peripherals.
