  • Page 6: Before Working Inside Your Computer

    Standby Power Dell products with standby power must be completely unplugged before the case is opened. Systems that incorporate standby power are essentially powered while turned off. The internal power enables the system to be remotely turned on (wake on LAN), suspended into a sleep mode, and have other advanced power management features.
  • Page 7 Due to the increased density of semiconductors used in recent Dell products, the sensitivity to static damage is now higher than in earlier Dell products. For this reason some previously approved methods of handling parts are no longer applicable.
  • Page 8 Figure 3. Chassis "Bare Metal" Grounding (Unacceptable) • Handle all static-sensitive components in a static-safe area. If possible, use anti-static floor pads and workbench pads. • When handling static-sensitive components, grasp them by the sides, not the top. Avoid touching pins and circuit boards. •...
  • Page 9 Figure 5. Anti-Static Mat The wrist strap and bonding wire can be either directly connected between your wrist and bare metal on the hardware if the ESD mat is not required, or connected to the anti-static mat to protect hardware that is temporarily placed on the mat. The physical connection of the wrist strap and bonding wire between your skin, the ESD mat, and the hardware is known as bonding.

  • Page 11 Figure 7. ESD Packaging Transporting Sensitive Components When transporting ESD-sensitive components such as replacement parts or parts to be returned to Dell, it is critical to place these parts in anti-static bags for safe transport. ESD Protection Summary It is strongly suggested that all field service engineers use the traditional wired ESD grounding wrist strap and protective anti-static mat at all times when servicing Dell products.

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 SuperSpeed 2010 Port USB 3.0/USB 3.1 Gen 1 (SuperSpeed USB) For years, the USB 2.0 has been firmly entrenched as the de facto interface standard in the PC world with about 6 billion devices sold, and yet the need for more speed grows by ever faster computing hardware and ever greater bandwidth demands.

  • Page 18: Usb Type-C

    Similarly, USB 3.0/USB 3.1 Gen 1 connections will never achieve 4.8Gbps. We will likely see a real-world maximum rate of 400MB/s with overheads. At this speed, USB 3.0/USB 3.1 Gen 1 is a 10x improvement over USB 2.0. Applications USB 3.0/USB 3.1 Gen 1 opens up the laneways and provides more headroom for devices to deliver a better overall experience. Where USB video was barely tolerable previously (both from a maximum resolution, latency, and video compression perspective), it's easy to imagine that with 5-10 times the bandwidth available, USB video solutions should work that much better.
