Electrostatic discharge—ESD protection
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 For this reason, some previously approved methods of handling parts are no longer applicable.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.
●Catastrophic – 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.
●Intermittent – 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 difficult type of damage to recognize and troubleshoot is the intermittent (also called latent or "walking wounded") failure.
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 floor pads and workbench pads.
●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.
ESD field service kit
The unmonitored Field Service kit is the most commonly used service kit. Each Field Service kit includes three main components:
anti-static mat, wrist strap, and bonding wire.
Components of an ESD field service kit
The components of an ESD field service kit are:
●Anti-Static Mat – The anti-static mat is dissipative and parts can be placed on it during service procedures. When using an
anti-static 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.
●Wrist Strap and Bonding Wire – The wrist strap and bonding wire can be either directly connected between your wrist and
bare metal 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.
●ESD Wrist Strap Tester – 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
6
best method for doing this test. If you do not have your own wrist strap tester, check with your regional office to find 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.
●Insulator Elements – It is critical to keep ESD sensitive devices, such as plastic heat sink casings, away from internal parts that are
insulators and often highly charged.
●Working Environment – Before deploying the ESD Field Service kit, assess the situation at the customer location. For example,
deploying the kit for a server environment is different 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 office desks or cubicles. Always look for a large open
flat work area 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
●ESD Packaging – 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, in the system, or inside an anti-static bag.
●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.
ESD protection summary
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.
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. Always obtain additional resources or use a mechanical lifting device.
1. Get a firm balanced footing. Keep your feet apart for a stable base, and point your toes out.
2. Tighten stomach muscles. Abdominal muscles support your spine when you lift, offsetting 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.

Troubleshooting
Handling swollen Lithium-ion batteries
Like most laptops, Dell laptops use lithium-ion batteries. One type of lithium-ion battery is the lithium-ion polymer battery. Lithium-
ion polymer batteries have increased in popularity in recent years and have become standard in the electronics industry due to
customer preferences for a slim form factor (especially with newer ultra-thin laptops) and long battery life. Inherent to lithium-ion
polymer battery technology is the potential for swelling of the battery cells.
Swollen battery may impact the performance of the laptop. To prevent possible further damage to the device enclosure or internal
components leading to malfunction, discontinue the use of the laptop and discharge it by disconnecting the AC adapter and letting
the battery drain.
Swollen batteries should not be used and should be replaced and disposed of properly. We recommend contacting Dell product
support for options to replace a swollen battery under the terms of the applicable warranty or service contract, including options for
replacement by a Dell authorized service technician.
The guidelines for handling and replacing Lithium-ion batteries are as follows:
●Exercise caution when handling Lithium-ion batteries.
●Discharge the battery before removing it from the system. To discharge the battery, unplug the AC adapter from the system
and operate the system only on battery power. When the system will no longer power on when the power button is pressed, the
battery is fully discharged.
●Do not crush, drop, mutilate, or penetrate the battery with foreign objects.
●Do not expose the battery to high temperatures, or disassemble battery packs and cells.
●Do not apply pressure to the surface of the battery.
●Do not bend the battery.
●Do not use tools of any type to pry on or against the battery.
●If a battery gets stuck in a device as a result of swelling, do not try to free it as puncturing, bending, or crushing a battery can be
dangerous.
●Do not attempt to reassemble a damaged or swollen battery into a laptop.
●Swollen batteries that are covered under warranty should be returned to Dell in an approved shipping container (provided by
Dell)—this is to comply with transportation regulations. Swollen batteries that are not covered under warranty should be disposed
of at an approved recycling center. Contact Dell product support at https://www.dell.com/support for assistance and further
instructions.
●Using a non-Dell or incompatible battery may increase the risk of fire or explosion. Replace the battery only with a compatible
battery purchased from Dell that is designed to work with your Dell computer. Do not use a battery from other computers with
your computer. Always purchase genuine batteries from https://www.dell.com or otherwise directly from Dell.
Lithium-ion batteries can swell for various reasons such as age, number of charge cycles, or exposure to high heat. For more
information on how to improve the performance and lifespan of the laptop battery and to minimize the possibility of occurrence of
the issue, see Dell Laptop Battery - Frequently Asked Questions.
Locate the Service Tag or Express Service Code of your
