Before Working Inside Your Tablet-PC

Use the following safety guidelines to help protect your Tablet-PC from potential damage and to help to ensure your own personal safety.

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.

NOTICE: 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.

NOTICE: 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.

NOTICE: 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.

NOTICE: To avoid damaging the Tablet-PC, perform the following steps before you begin working inside the Tablet-PC.

1Ensure that the work surface is flat and clean to prevent the Tablet-PC cover from being scratched.

2Turn off your Tablet-PC (see "Turning Off Your Tablet-PC" on page 155).
