Page 6: Working On Your Computer
Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product. -
Page 7: Safety Precautions
Due to the increased density of semiconductors used in recent Dell products, the sensitivity to static damage is now higher than in previous Dell products. For this reason, some previously approved methods of handling parts are no longer applicable. -
Page 8: Esd Field Service Kit
It is recommended that all field service technicians use the traditional wired ESD grounding wrist strap and protective anti-static mat at all times when servicing Dell products. In addition, it is critical that technicians keep sensitive parts separate from all insulator parts while performing service and that they use anti-static bags for transporting sensitive components. -
Page 9: Transporting Sensitive Components
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. Lifting equipment Adhere to the following guidelines when lifting heavy weight equipment: CAUTION: Do not lift greater than 50 pounds. -
Page 10: Technology And Components
Technology and components This chapter details the technology and components available in the system. Topics: • DDR4 • USB features • USB Type-C • Advantages of DisplayPort over USB Type-C • HDMI 2.0 • 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. -
Page 11: Memory Errors
Figure 2. Thickness difference 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. -

finally has the answer to the consumers' demands with a theoretically 10 times faster than its predecessor. In a nutshell, USB 3.1 Gen 1 features are as follows: • Higher transfer rates (up to 5 Gbps) • Increased maximum bus power and increased device current draw to better accommodate power-hungry devices •... -
Page 13: Applications
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. -
Page 14: Usb Power Delivery
USB Power Delivery The USB PD specification is also closely intertwined with USB Type-C. Currently, smartphones, tablets, and other mobile devices often use a USB connection to charge. A USB 2.0 connection provides up to 2.5 watts of power — that'll charge your phone, but that's about it. A laptop might require up to 60 watts, for example. -
Page 15: Advantages Of Hdmi
• HDMI Micro Connector - A new, smaller connector for phones and other portable devices, supporting video resolutions up to 1080p • Automotive Connection System - New cables and connectors for automotive video systems, designed to meet the unique demands of the motoring environment while delivering true HD quality Advantages of HDMI •... - Page 16 NOTE: Disabling Intel Optane memory is required before removing the SATA storage device, accelerated by the Intel Optane memory module, from the computer. On the taskbar, click the search box, and then type "Intel Rapid Storage Technology". Click Intel Rapid Storage Technology. The Intel Rapid Storage Technology window is displayed. On the Intel Optane memory tab, click Disable to disable the Intel Optane memory.
