Technology and components
This chapter details the technology and components available in the system.
Topics:
• Power adapter
• DDR4
• HDMI 1.4- HDMI 2.0
• USB features
• USB Type-C
Power adapter
This laptop is shipped with 7.4 mm barrel plug on power adapter.
WARNING: When you disconnect the power adapter cable from the laptop, grasp the connector, not the cable itself, and then
pull rmly but gently to avoid damaging the cable.
WARNING: The power adapter works with electrical outlets worldwide. However, power connectors and power strips vary
among countries. Using an incompatible cable or improperly connecting the cable to the power strip or electrical outlet may
cause re or equipment damage.
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. DDR4 synchronous dynamic random-access memory is keyed
dierently from both SDRAM and DDR to prevent the user from installing the wrong type of memory into the system.
DDR4 needs 20 percent less or just 1.2 volts, compared to DDR3 which requires 1.5 volts of electrical power to operate. DDR4 also supports
a new, deep power-down mode that allows the host device to go into standby without needing to refresh its memory. Deep power-down
mode is expected to reduce standby power consumption by 40 to 50 percent.
DDR4 Details
There are subtle dierences between DDR3 and DDR4 memory modules, as listed below.
Key notch dierence
The key notch on a DDR4 module is in a dierent location from the key notch on a DDR3 module. Both notches are on the insertion edge
but the notch location on the DDR4 is slightly dierent, to prevent the module from being installed into an incompatible board or platform.

8 Technology and components
Figure 1. Notch dierence
Increased thickness
DDR4 modules are slightly thicker than DDR3, to accommodate more signal layers.
Figure 2. Thickness dierence
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.
NOTE: The DDR4 memory is imbedded in board and not a replaceable DIMM as shown and referred.
HDMI 1.4- HDMI 2.0
This topic explains the HDMI 1.4 and its features along with the advantages.
HDMI (High-Denition 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. The primary advantage is cable
Technology and components 9
reduction and content protection provisions. HDMI supports standard, enhanced, or high-denition video, plus multichannel digital audio on
a single cable.
NOTE: The HDMI 1.4 will provide 5.1 channel audio support.
HDMI 1.4- HDMI 2.0 Features
•HDMI Ethernet Channel - Adds high-speed networking to an HDMI link, allowing users to take full advantage of their IP-enabled
devices without a separate Ethernet cable
•Audio Return Channel - Allows an HDMI-connected TV with a built-in tuner to send audio data "upstream" to a surround audio system,
eliminating the need for a separate audio cable
•3D - Denes input/output protocols for major 3D video formats, paving the way for true 3D gaming and 3D home theater applications
•Content Type - Real-time signaling of content types between display and source devices, enabling a TV to optimize picture settings
based on content type
•Additional Color Spaces - Adds support for additional color models used in digital photography and computer graphics
•4K Support - Enables video resolutions far beyond 1080p, supporting next-generation displays that will rival the Digital Cinema systems
used in many commercial movie theaters
•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
• Quality HDMI transfers uncompressed digital audio and video for the highest, crispest image quality.
• Low -cost HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a
simple, cost-eective manner
• Audio HDMI supports multiple audio formats from standard stereo to multichannel surround sound
• HDMI combines video and multichannel audio into a single cable, eliminating the cost, complexity, and confusion of multiple cables
currently used in A/V 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 simplied 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 3.1 Gen 1 (SuperSpeed USB)
For years, the USB 2.0 has been rmly 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. The USB 3.0/USB 3.1 Gen 1
10 Technology and components
nally 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
• New power management features
• Full-duplex data transfers and support for new transfer types
• Backward USB 2.0 compatibility
• New connectors and cable
The topics below cover some of the most commonly asked questions regarding USB 3.0/USB 3.1 Gen 1.
Speed
Currently, there are 3 speed modes dened by the latest USB 3.0/USB 3.1 Gen 1 specication. They are Super-Speed, Hi-Speed and Full-
Speed. The new SuperSpeed mode has a transfer rate of 4.8Gbps. While the specication retains Hi-Speed, and Full-Speed USB mode,
commonly known as USB 2.0 and 1.1 respectively, the slower modes still operate at 480Mbps and 12Mbps respectively and are kept to
maintain backward compatibility.
USB 3.0/USB 3.1 Gen 1 achieves the much higher performance by the technical changes below:
• An additional physical bus that is added in parallel with the existing USB 2.0 bus (refer to the picture below).
• USB 2.0 previously had four wires (power, ground, and a pair for dierential data); USB 3.0/USB 3.1 Gen 1 adds four more for two pairs
of dierential signals (receive and transmit) for a combined total of eight connections in the connectors and cabling.
• USB 3.0/USB 3.1 Gen 1 utilizes the bidirectional data interface, rather than USB 2.0's half-duplex arrangement. This gives a 10-fold
increase in theoretical bandwidth.
With today's ever increasing demands placed on data transfers with high-denition 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. 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.
Technology and components 11
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. Single-link DVI requires almost 2Gbps
throughput. Where 480Mbps was limiting, 5Gbps is more than promising. With its promised 4.8Gbps speed, the standard will nd its way
into some products that previously weren't USB territory, like external RAID storage systems.
Listed below are some of the available SuperSpeed USB 3.0/USB 3.1 Gen 1 products:
• External Desktop USB 3.0/USB 3.1 Gen 1 Hard Drives
• Portable USB 3.0/USB 3.1 Gen 1 Hard Drives
• USB 3.0/USB 3.1 Gen 1 Drive Docks & Adapters
• USB 3.0/USB 3.1 Gen 1 Flash Drives & Readers
• USB 3.0/USB 3.1 Gen 1 Solid-state Drives
• USB 3.0/USB 3.1 Gen 1 RAIDs
• Optical Media Drives
• Multimedia Devices
• Networking
• USB 3.0/USB 3.1 Gen 1 Adapter Cards & Hubs
Compatibility
The good news is that USB 3.0/USB 3.1 Gen 1 has been carefully planned from the start to peacefully co-exist with USB 2.0. First of all,
while USB 3.0/USB 3.1 Gen 1 species new physical connections and thus new cables to take advantage of the higher speed capability of
the new protocol, the connector itself remains the same rectangular shape with the four USB 2.0 contacts in the exact same location as
before. Five new connections to carry receive and transmitted data independently are present on USB 3.0/USB 3.1 Gen 1 cables and only
come into contact when connected to a proper SuperSpeed USB connection.
Windows 8/10 will be bringing native support for USB 3.1 Gen 1 controllers. This is in contrast to previous versions of Windows, which
continue to require separate drivers for USB 3.0/USB 3.1 Gen 1 controllers.
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 conrmed this by stating that most of their partners share the opinion that
Vista should also support USB 3.0/USB 3.1 Gen 1.
Advantages of Displayport over USB Type-C
• Full DisplayPort audio/video (A/V) performance (up to 4K at 60Hz)
• SuperSpeed USB (USB 3.1) data
• Reversible plug orientation and cable direction
• Backwards compatibility to VGA, DVI with adaptors
• Supports HDMI 2.0a and is backwards compatible with previous versions
USB Type-C
USB Type-C is a new, tiny physical connector. The connector itself can support various exciting new USB standard like USB 3.1 and USB
power delivery (USB PD).
12 Technology and components
Alternate Mode
USB Type-C is a new connector standard that's very small. It's about a third the size of an old USB Type-A plug. This is a single connector
standard that every device should be able to use. USB Type-C ports can support a variety of dierent protocols using “alternate modes,”
which allows you to have adapters that can output HDMI, VGA, DisplayPort, or other types of connections from that single USB port
USB Power Delivery
The USB PD specication 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. The USB Power Delivery specication ups this power delivery to 100 watts. It's bi-
directional, so a device can either send or receive power. And this power can be transferred at the same time the device is transmitting
data across the connection.
This could spell the end of all those proprietary laptop charging cables, with everything charging via a standard USB connection. You could
charge your laptop from one of those portable battery packs you charge your smartphones and other portable devices from today. You
could plug your laptop into an external display connected to a power cable, and that external display would charge your laptop as you used
it as an external display — all via the one little USB Type-C connection. To use this, the device and the cable have to support USB Power
Delivery. Just having a USB Type-C connection doesn't necessarily mean they do.
USB Type-C and USB 3.1
USB 3.1 is a new USB standard. USB 3's theoretical bandwidth is 5 Gbps, while USB 3.1 Gen2 is10Gbps . That's double the bandwidth, as
fast as a rst-generation Thunderbolt connector. USB Type-C isn't the same thing as USB 3.1. USB Type-C is just a connector shape, and
the underlying technology could just be USB 2 or USB 3.0. In fact, Nokia's N1 Android tablet uses a USB Type-C connector, but underneath
it's all USB 2.0 — not even USB 3.0. However, these technologies are closely related.

Enhanced Pre-Boot System Assessment — ePSA
diagnostics
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. The embedded system diagnostics provides a set of options for particular devices or device
groups allowing you to:
• Run tests automatically or in an interactive mode
• Repeat tests
• Display or save test results
• Run thorough tests to introduce additional test options to provide extra information about the failed device(s)
• View status messages that inform you if tests are completed successfully
• View error messages that inform you of problems encountered during testing
CAUTION: Use the system diagnostics to test only your computer. Using this program with other computers may cause invalid
