Marketing Information
The Latitude™ D620 is positioned as Latitude's mainstream thin and light D-Family product, designed for workers who frequently travel and value mainstream
performance with full-size 14.1" displays and integrated optical drives. It targets large corporate accounts with a strong focus on manageability, cost of ownership,
security, and integrated communications delivered in a notebook with a high level of quality, fit, and finish.
The D620 replaces the D610 as Latitude's mainstream thin and light corporate notebook. It is a 2-spindle design optimized around a wide-aspect 14.1" display. The
D620 delivers mainstream performance with the Intel® Napa architecture, the new Latitude Laminar design language, and integrated wireless communications
(including support for integrated configurable cellular WAN), all at a lower weight than the D610 with an optimized profile height associated with the wide-aspect display.
Cost for the D620 is managed with the goal of cost-point replacement to the D610.
The Latitude brand promise is maintained by offering managed transitions, system manageability, and essential commonality with the Latitude D-Family. The D620 is
compatible with the D-Family docking, AC adapters, and D-Family media modules and peripherals. This system supports key D-Family features such as smart card
technology, TPM, gigabit Ethernet, mini card slots, and dual-pointing devices.
These are some of the goals considered in the Latitude D620's development:
● Delivery of Intel's Napa architecture (features/performance)
● D-Family commonality
● Size and weight
● Battery life
● Cost
● RoHS compliance

Chassis Overview
Three different batteries are available for the Latitude™ D620 system. The chassis appearance changes when the 9-cell battery is installed. The 9-cell battery includes a palm
rest of sorts that protrudes from the front of the system. The top of the battery palm rest is level with the system palm rest. It does not detach from the battery since it is part of the
battery.
The chassis section is broken down into two groups of pictures: One group contains photos of the system with the 6-cell or 4-cell battery installed, and the second contains
pictures of the system with the 9-cell battery installed. Click all photos in both sections to view larger images in a new browser window.

Safety Precautions
Observe the following safety precautions before performing any installation or break/fix procedures involving disassembly or re-assembly:
● Turn off the system and any attached peripherals.
● Disconnect the system and any attached peripherals from AC power, and then remove the battery.
● Disconnect any telephone or telecommunications lines from the system.
● Use a wrist grounding strap and mat when working inside any computer system to avoid electrostatic discharge (ESD) damage.
● After removing any system component, carefully place the removed component on an anti-static mat.
● Wear shoes with non-conductive rubber soles to help reduce the chance of being shocked or seriously injured in an electrical accident.
Standby Power
Dell products with standby power must be completely unplugged before opening the case. Systems that incorporate standby power are essentially powered while turned off. The internal power allows the system to be remotely turned
on (wake on LAN), suspended into a sleep mode, and have other advanced power management features. After unplugging the system, allow the charge to drain from the circuits by waiting approximately 30 to 45 seconds before
removing components.
ESD
ESD is a major concern when handling components, especially expansion cards and system boards. Very slight charges can damage circuits in ways that may not be obvious, such as intermittent problems or a shortened product
lifespan.
WARNING:
Do not use an ESD grounding strap when working on the internal parts of a monitor, like the CRT, because the stored voltage is extremely harmful.
To prevent static damage, do the following:
● Use an ESD wrist strap that is properly grounded.
● If a strap is not available, discharge static electricity from your body before you touch any of your computer's electronic components, by touching an unpainted metal surface on the computer chassis. Periodically touch an
unpainted metal surface to remove any static charge your body may have accumulated.
● Handle all static-sensitive components in a static-safe area. If possible, use anti-static floor pads and workbench pads.
● When handling static-sensitive components, grab them by the sides, not the top. Avoid touching pins and circuit boards.
● 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, be sure to discharge static electricity from your body.
● Before transporting a static-sensitive component, place it in an anti-static container or packaging.
Lifting Equipment
CAUTION:
Do not lift greater than 50 pounds independently. Always obtain assistance from a second person or utilize a mechanical lifting device.
Adhere to the following guidelines when lifting equipment:
1. Get a firm balanced footing. Keep your feet apart for a stable base, and point your toes out.
2. Bend your knees. Do not bend at the waist.
3. Tighten stomach muscles. Abdominal muscles support your spine when you lift, offsetting the force of the load.
4. Lift with your legs, not your back.
5. Keep the load close. The closer it is to your spine, the less force it exerts on your back.
6. 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.
7. Follow the same techniques in reverse to set the load down.

Service Issues
You need to address the following issues when replacing parts on the Latitude™ D620.
Palm Rest Removal
The palm rest on this system needs to be removed in a certain manner. Follow these steps:
1. Remove all parts necessary to access the palm rest.
2. Remove the nine securing screws from the bottom section of the system.
3. Remove the three palm rest screws from the upper section of the system.
4. Disconnect the cable connector attached to the system board located on the left side of the system.
5. Starting with the back of the palm rest (located near the LCD mounts), separate the palm rest from the base of the system, and work it loose along the sides towards the front.
WARNING:
You must start removing the palm rest from the back. Failure to do so will damage the connector hooks located along the front edge of the base plastics.
6. Once the back and sides of the palm rest are free, slide it forward to release it from the securing hooks located along the front edge of the base plastics.
7. Remove the palm rest from the system.
System Board Replacement
The system board removal is straightforward. However, replacing it correctly involves lining up the wireless sniffer switch correctly, or the board does
not seat properly in the system.
When you reseat the system board, the wireless switch must line up with the plastics as shown to the right. If it is not lined up correctly, the board does
not seat down fully and hangs over the right edge of the bottom plastics. At no point should you force the board into place; this will damage the plastics,
the switch, or worse.
The easiest method of aligning the switch with the plastics is to have both the interior switch on the system board as well as the exterior switch on the
outer plastics in the "off" position, all the way towards the back of the unit (closest to the LCD).
