Before Working Inside Your Tablet
Prerequisites
Use the following safety guidelines to help protect your tablet from potential damage and to help to ensure your personal safety.
Unless otherwise noted, each procedure included in this document assumes that the following condition exists:
● You have read the safety information that shipped with your tablet.
About this task
NOTE:
Before working inside your tablet, read the safety information that shipped with your tablet. For additional safety
best practices information, see the Regulatory Compliance Homepage at www.dell.com/regulatory_compliance
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, such as a connector on the back of the tablet.
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.
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.
NOTE: The color of your tablet and certain components may appear differently than shown in this document.
To avoid damaging your tablet, perform the following steps before you begin working inside the tablet.
Steps
1. Ensure that your work surface is flat and clean to prevent the tablet cover from being scratched.
2. Turn off your tablet.
3. If the tablet is connected to a docking device (docked) such as the optional docking station or keyboard dock, un-dock it.
4. Disconnect the power adapter from the tablet.
