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 the reverse order.

NOTE: Disconnect all power sources before opening the computer cover or panels. After you finish working inside the

computer, replace all covers, panels, and screws before connecting to the power source.

CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and

simple repairs as authorized in your product documentation, or as directed by the online or telephone service and

support team. 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.

CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching

an unpainted metal surface that is grounded to ground yourself before you touch the computer to perform any

disassembly tasks.

CAUTION: Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by

its edges or by its metal mounting bracket. Hold a component such as a processor by its edges, not by its pins.

CAUTION: When you disconnect a cable, pull on its connector or on its pull-tab, not on the cable itself. Some cables

have connectors with locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before you

disconnect the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also,

before you connect a cable, ensure that both connectors are correctly oriented and aligned.

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 4. 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 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. The USB 3.0/USB 3.1 Gen 1

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

• 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.

Technology and components 49

Speed

Currently, there are 3 speed modes defined by the latest USB 3.0/USB 3.1 Gen 1 specification. They are Super-Speed, Hi-Speed and Full-

Speed. The new SuperSpeed mode has a transfer rate of 4.8Gbps. While the specification 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 differential data); USB 3.0/USB 3.1 Gen 1 adds four more for two

pairs of differential 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-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. 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. 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 find 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

50 Technology and components

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 specifies 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 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.

HDMI 1.4

This topic explains the HDMI 1.4 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. The primary advantage is cable

reduction and content protection provisions. HDMI supports standard, enhanced, or high-definition video, plus multichannel digital audio

on a single cable.

NOTE: The HDMI 1.4 will provide 5.1 channel audio support.

HDMI 1.4 Features

•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-effective 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 Powershare

USB PowerShare is a feature which allows for external USB devices (i.e. cellular phones, portable music players, etc.) to charge using the

portable system's battery.

Technology and components 51

Only the USB connector with a SS+USB+Battery--> icon, can be used.

This functionality is enabled in the system setup under the On Board Devices heading. You can select how much of the battery's charge

can be used as well (pictured below). If you set the USB PowerShare to 25%, the external device is allowed to charge until the battery

reaches 25% of full capacity (e.g. 75% of the portable's battery charge is used up).

Issue Suggested Troubleshooting Steps

Battery Charging The battery should be charged while the system is off for faster charge time. Users may notice longer

charge times when the system is turned on and running graphics-intensive applications.

CAUTION: There is a danger of a new battery exploding if it is incorrectly installed. Replace

the battery only with the same or equivalent type recommended by the manufacturer.

Discard used batteries according to the manufacturer's instructions.

No POST When a user starts the notebook, the first thing that the BIOS does is to perform the Power-On Self-Test

(POST). The POST is a built-in diagnostic program that checks the hardware to make sure that

everything is present and functioning properly, before the BIOS begins the actual boot.

If the system does not perform a Power-On Self-Test, there are various things that you can look for:

1. Check that the system has a power light.

2. If the system has no power light, make sure that it is plugged into AC power.

3. Remove the battery. Make sure that the power is turned off and the system is unplugged.

4. Remove all CRUs from the system and reconnect the AC adapter to the system and try again.

5. Run the ePSA diagnostics.

Video If the LCD on the system does not show any display or has other problems, here are some basic steps

that you can perform:

1. If the LCD is not displaying video or the video is garbled, run the ePSA diagnostics.

2. If the LCD is not displaying any video, connect an external monitor to eliminate a no-POST problem. A

good image on the external monitor eliminates a video card problem or a POST problem.

3. Connect an external monitor, when possible, for all LCD-related problems to help eliminate a possible

software or video card problem.

4. If the LCD has dim video, adjust the brightness or connect an AC adapter to eliminate a power

management conservation setting in the BIOS.

5. If the LCD has lines on the screen, check the system during POST and system setup, to determine if

the lines are present in all modes of operation. Run the ePSA diagnostics.

6. If the LCD has color problems, run the ePSA diagnostics.

7. If the LCD has burned-out pixels, verify that the LCD is still within LCD standard guidelines. For Dell

internal users only, click here.

BIOS If users have problems while using the notebook, the problems may be related to BIOS settings

configured incorrectly in BIOS/System Setup. Check the System Setup pages to verify the settings on

each page. Try resetting BIOS to default settings by pressing Alt+F.

Touchpad and Keyboard To troubleshoot touchpad and keyboard-related problems, you can perform the following steps:

1. Attach an external mouse or keyboard to check for peripheral functionality.

2. Run the ePSA diagnostics.

Integrated NIC If the system is not able to identify any network after connecting the network cable to the network port,

try the following troubleshooting steps:

1. Make sure that the network driver has been installed and is working properly.

2. Check System Setup to make sure that the NIC is enabled.

3. Try reseating the cable.

4. Try a known good cable, if one is available.

5. If a known good system is available, check if that system is connecting to the network.

72 Troubleshooting

Issue Suggested Troubleshooting Steps

6. Run the ePSA diagnostics on the network port.

NOTE: If the integrated network hardware solution is defective or nonfunctional, replace

the system board.

VGA No additional drivers or updates are needed for VGA functionality. When troubleshooting an external

monitor, keep these tips in mind:

• Check both ends of the cable for a snug connection into the laptop and into the external monitor.

• Adjust the contrast and brightness controls on the external monitor.

• Make sure that the notebook is not set to internal display only.

• Swap with a known good cable.

• Try with a known good external monitor. Check the external device's documentation for any additional

steps required for functionality.

NOTE: If the VGA hardware port is defective or nonfunctional, replace the system board.

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:

The ePSA diagnostics can be initiated by the FN+PWR buttons while powering on the computer.

• 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

NOTE: Some tests for specific devices require user interaction. Always ensure that you are present at the computer

terminal when the diagnostic tests are performed.

System diagnostic lights

Power and battery-status light/ hard-drive activity light: Indicates the battery-charge status or the hard-drive activity.

NOTE: Press Fn+H to toggle this light between power and battery-status light and hard-drive activity light.

Hard-drive activity light

Turns on when the computer reads from or writes to the hard drive.

Power and battery-status light

Indicates the power and battery-charge status.

Solid white – Power adapter is connected and the battery has more than 5 percent charge.

Amber – Computer is running on battery and the battery has less than 5 percent charge.

Off

• Power adapter is connected and the battery is fully charged.

• Computer is running on battery and the battery has more than 5 percent charge.

Troubleshooting 73

• Computer is in sleep state, hibernation, or turned off.

The power and battery-status light blinks amber along with beep codes indicating failures.

For example, the power and battery-status light blinks amber two times followed by a pause, and then blinks white three times followed by
