The safety precautions chapter details the primary steps to be taken before performing any disassembly instructions.
Observe the following safety precautions before you perform any installation or break/x procedures involving disassembly or reassembly:
‱ Turn o the system and all attached peripherals.
‱ Disconnect the system and all attached peripherals from AC power.
‱ Disconnect all network cables, telephone, and telecommunications lines from the system.
‱ Use an ESD service kit when working inside any notebook to avoid electrostatic discharge (ESD) damage.eld
‱ After removing any system component, carefully place the removed component on an anti-static mat.
‱ Wear shoes with non-conductive rubber soles to reduce the chance of getting electrocuted.

Dell products with standby power must be unplugged before you open the case. Systems that incorporate standby power are essentially
powered while turned o. The internal power enables the system to be remotely turned on (wake on LAN) and suspended into a sleep
mode and has other advanced power management features.
Unplugging, pressing and holding the power button for 15 seconds should discharge residual power in the system board, notebooks.

Bonding Bonding
Bonding is a method for connecting two or more grounding conductors to the same electrical potential. This is done through the use of a
eld service electrostatic discharge (ESD) kit. When connecting a bonding wire, ensure that it is connected to bare metal and never to a
painted or non-metal surface. The wrist strap should be secure and in full contact with your skin, and ensure that you remove all jewelry
such as watches, bracelets, or rings prior to bonding yourself and the equipment.

ESD is a major concern when you handle electronic components, especially sensitive components such as expansion cards, processors,
memory DIMMs, and system boards. Very slight charges can damage circuits in ways that may not be obvious, such as intermittent
problems or a shortened product life span. As the industry pushes for lower power requirements and increased density, ESD protection is an
increasing concern.
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 For this reason, some previously approved methods of handling parts are no longer applicable.

Two recognized types of ESD damage are catastrophic and intermittent failures.
‱Catastr
Catastr
Catastr
CatastrCatastrophic
ophic

ophicophic – Catastrophic failures represent approximately 20 percent of ESD-related failures. The damage causes an immediate and
complete loss of device functionality. An example of catastrophic failure is a memory DIMM that has received a static shock and
immediately generates a "No POST/No Video" symptom with a beep code emitted for missing or nonfunctional memory.
‱Int
Int

tt – Intermittent failures represent approximately 80 percent of ESD-related failures. The high rate of intermittent failures
means that most of the time when damage occurs, it is not immediately recognizable. The DIMM receives a static shock, but the
tracing is merely weakened and does not immediately produce outward symptoms related to the damage. The weakened trace may
take weeks or months to melt, and in the meantime may cause degradation of memory integrity, intermittent memory errors, etc.
The more type of damage to recognize and troubleshoot is the intermittent (also called latent or "walking wounded") failure.dicult
Perform the following steps to prevent ESD damage:
‱ Use a wired ESD wrist strap that is properly grounded. The use of wireless anti-static straps is no longer allowed; they do not provide
adequate protection. Touching the chassis before handling parts does not ensure adequate ESD protection on parts with increased
sensitivity to ESD damage.
‱ Handle all static-sensitive components in a static-safe area. If possible, use anti-static pads and workbench pads.oor
‱ When unpacking a static-sensitive component from its shipping carton, do not remove the component from the anti-static packing
material until you are ready to install the component. Before unwrapping the anti-static packaging, ensure that you discharge static
electricity from your body.
‱ Before transporting a static-sensitive component, place it in an anti-static container or packaging.

mat, your wrist strap should be snug and the bonding wire should be connected to the mat and to any bare metal on the system being
worked on. Once deployed properly, service parts can be removed from the ESD bag and placed directly on the mat. ESD-sensitive
items are safe in your hand, on the ESD mat, in the system, or inside a bag.

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. Use only Field Service kits with a wrist strap, mat, and bonding wire. Never use wireless wrist straps. Always be aware that the
internal wires of a wrist strap are prone to damage from normal wear and tear, and must be checked regularly with a wrist strap tester
in order to avoid accidental ESD hardware damage. It is recommended to test the wrist strap and bonding wire at least once per week.

esterester – The wires inside of an ESD strap are prone to damage over time. When using an unmonitored kit, it is a best
practice to regularly test the strap prior to each service call, and at a minimum, test once per week. A wrist strap tester is the best
method for doing this test. If you do not have your own wrist strap tester, check with your regional oce nd to out if they have one.
To perform the test, plug the wrist-strap's bonding-wire into the tester while it is strapped to your wrist and push the button to test. A
green LED is lit if the test is successful; a red LED is lit and an alarm sounds if the test fails.

deploying the kit for a server environment is dierent than for a desktop or portable environment. Servers are typically installed in a rack
within a data center; desktops or portables are typically placed on desks or cubicles. Always look for a large open work area oce at
that is free of clutter and large enough to deploy the ESD kit with additional space to accommodate the type of system that is being
repaired. The workspace should also be free of insulators that can cause an ESD event. On the work area, insulators such as Styrofoam
and other plastics should always be moved at least 12 inches or 30 centimeters away from sensitive parts before physically handling any
hardware components
‱ – All ESD-sensitive devices must be shipped and received in static-safe packaging. Metal, static-shielded bags are

preferred. However, you should always return the damaged part using the same ESD bag and packaging that the new part arrived in.
The ESD bag should be folded over and taped shut and all the same foam packing material should be used in the original box that the
new part arrived in. ESD-sensitive devices should be removed from packaging only at an ESD-protected work surface, and parts should

never be placed on top of the ESD bag because only the inside of the bag is shielded. Always place parts in your hand, on the ESD mat,

It is recommended that all service technicians use the traditional wired ESD grounding wrist strap and protective anti-static mat at all eld
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.

2 Tighten stomach muscles. Abdominal muscles support your spine when you lift, osetting the force of the load.
3 Lift with your legs, not your back.
4 Keep the load close. The closer it is to your spine, the less force it exerts on your back.
5 Keep your back upright, whether lifting or setting down the load. Do not add the weight of your body to the load. Avoid twisting your
body and back.
6 Follow the same techniques in reverse to set the load down.

the same icons in a web browser are not grayed out. For
example, if the back button on a web page is grayed, this is
because the browser is not aware of a page to move

This topic covers the information you need to know for the Chrome Shell (CROSH). CROSH and the Google Chrome URL commands
provide some troubleshooting tools, information, and advanced settings.
The Chrome OS does not support ePSA, Dell BIOS, the F12 boot menu, or DellConnect. There are no preboot diagnostics. All
troubleshooting must be done inside the OS. Chrome Shell (CROSH) and the Chrome URL commands provide some troubleshooting tools,
information, and advanced settings. CROSH is a command line interface similar to the Linux BASH or Windows command (cmd.exe)
terminals. Chrome OS is based on Linux, but CROSH does not recognize most Linux commands. The most useful commands for
troubleshooting are memory test, storage_test_1, storage_test_2, ping, and tracepath. Ping works dierently than it does in Windows. By
default, it repeats until you press , and it does not show any statistics. The tracepath command is similar to the Windows
<Ctrl> + <C>
<Ctrl> + <C>
<Ctrl> + <C>
<Ctrl> + <C><Ctrl> + <C>
traceroute command. A detailed explanation of the commands can be viewed below, by typing help, or help_advanced in CROSH.
