Power adapter
This laptop is shipped with 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.
USB features
The Universal Serial Bus, or well known as USB was introduced to the PC world in 1996 which dramatically simplied the connection
between host computer and peripheral devices such as mice and keyboards, external hard drive or optical devices, Bluetooth and many
more peripheral devices in the market.
Let's take a quick look on the USB evolution referencing to the table below.
Table 2. USB evolution
Type Data Transfer Rate Category Introduction Year
USB 3.0/USB 3.1 Gen 1 5 Gbps Super Speed 2010
USB 2.0 480 Mbps High Speed 2000
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
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
3
46 Technology and components
• 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.
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:
Technology and components 47
• 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.
Super-Speed support for Windows XP is unknown at this point. Given that XP is a seven-year-old operating system, the likelihood of this
happening is remote.

This section details the diagnostic features of the battery LED in a notebook.
Instead of beep codes errors are indicated via the bicolor Battery Charge LED. A specic blink pattern is followed by ashing a pattern of
ashes in amber, followed by white. The pattern then repeats.
NOTE: The diagnostic pattern will consist of a two digit number being represented by a rst group of LED blinks (1 through 9) in
amber, followed by a 1.5 second pause with the LED o, and then a second group of LED blinks (1 through 9) in white. This is
then followed by a three second pause, with the LED o, before repeating over again. Each LED blink takes 0.5 seconds.
The system will not shutdown when displaying the Diagnostic Error Codes. Diagnostic Error Codes will always supersede any other use of
the LED. For instance, on Notebooks, battery codes for Low Battery or Battery Failure situations will not be displayed when Diagnostic
Error Codes are being displayed:

Issue Suggested Troubleshooting Steps
Battery Charging The battery should be charged while the system is o 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 tablet, the rst 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 o 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 tablet, the problems may be related to BIOS settings congured
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:
Troubleshooting 73
Issue Suggested Troubleshooting Steps
1 Make sure that the network driver has been installed and is working properly.
2 Check that the network LEDs are responding.
3 Check System Setup to make sure that the NIC is enabled.
4 Try reseating the cable.
5 Try a known good cable, if one is available.
6 If a known good system is available, check if that system is connecting to the network.
7 Run the ePSA diagnostics on the network port.
NOTE: If the integrated network hardware solution is defective or nonfunctional, replace the
system board.
Display assembly 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 tablet 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 display assembly is defective or nonfunctional, replace the defective components.
