WARNING: Before working inside your Tablet-PC, read the safety information that shipped with your Tablet-PC. For additional safety best

practices information, see the Regulatory Compliance Homepage at www.dell.com/regulatory_compliance.

CAUTION: Only a certified service technician should perform repairs on your Tablet-PC. Damage due to servicing that is not authorized by Dell is

not covered by your warranty.

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 computer.

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. Hold a component such as a processor by its edges, not by its pins.

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-PC and certain components may appear differently than shown in this document.

CAUTION: To disconnect a network cable, first unplug the cable from your Tablet-PC and then unplug the cable from the network device.

CAUTION: To avoid damaging the system board, you must remove the main battery before you service the Tablet-PC.

CAUTION: To guard against electrical shock, always unplug your Tablet-PC from the electrical outlet before opening the display.

CAUTION: Before touching anything inside your Tablet-PC, ground yourself by touching an unpainted metal surface, such as the metal at the back

of the Tablet-PC. While you work, periodically touch an unpainted metal surface to dissipate static electricity, which could harm internal

components.

CAUTION: To avoid losing data, save and close all open files and exit all open programs before you turn off your Tablet-PC.
