Using your tablet

This section covers how to power on and turn o your tablet including how to install the micro SD and uSIM cards.

Topics:

• Deploying the kickstand

• Before Working Inside Your Tablet

• After working inside your tablet

• Installing a microSD and/or micro-SIM card

Deploying the kickstand

1 Hold the tablet vertically on a plane surface.

2 Press the tablet to allow the kickstand to open.

2

Using your tablet 11

NOTE: The pegs at the bottom of the tablet allow the kickstand to open.

Before Working Inside Your Tablet

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.

WARNING: 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 certied 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 dierently than shown in this document.

To avoid damaging your tablet, perform the following steps before you begin working inside the tablet.

5 Press and hold the power button for a few seconds to remove the ea power from the system board.

CAUTION

CAUTION: Before touching anything inside your tablet, ground yourself by touching an unpainted metal surface, such as

the metal at the back of the tablet. While you work, periodically touch an unpainted metal surface to dissipate static
electricity, which could harm internal components.

6 Remove the storage SD card from the tablet.

Troubleshooting

Enhanced Pre-boot System Assessment (ePSA)

The ePSA is a diagnostic utility available on the tablet. This utility includes a series of tests for a tablet's hardware. Customers can run these
tests even if the computer lacks any media (hard drive, CD drive, etc.). If an ePSA-tested component fails, the system displays an error
code and generates a beep code.

Features:

• Graphical User Interface.

• Automatic Default Operation- runs test on all devices, allowing a user to interrupt and select any device.

• Checks the Master Boot Record for readiness to boot into a full OS environment.

• Tablet panel test.

• Video card.

• Battery test.

• Charger test.

• Primary battery.

• Multiprocessor cache test.

Running the ePSA Diagnostic Utility

: The following steps can be used to run the ePSA diagnostic utility in DOS mode without using an external keyboard.

NOTE

1 Power on the system.

2 Before the Dell Logo is displayed, immediately press the Volume Up button to get the Boot Menu

3 Scroll down the Diagnostics and then press the Volume Down button to select

4 The tablet will begin running the ePSA utility.

Tablet LED

This section details the diagnostic features of the battery LED in a tablet.

Diagnostic LED

Tablets rely on the Battery LED light blinking amber/white pattern to determine failures listed in the following table:

34 Troubleshooting

NOTE:

• The blinking patterns will consist of 2 sets of numbers being represented by (First Group: Amber blinks, Second Group: White
blinks)

• First Group : The LED blinks 1 to 9 times followed by a brief pause with LED o at the interval of 1.5 seconds. (This is in Amber
color)

• Second Group : The LED blinks 1 to 9 times, that would be then followed by a longer pause before the next cycle starts again at the
interval of 1.5 seconds. (This is in White color)

• Example: No Memory detected (2,3), Battery LED blinks two times of amber color followed by a pause, and then blinks three times
of white color. The Battery LED will pause for 3 seconds before the next cycle repeat itself again

The following table depicts the amber and white blinking patterns with possible troubleshooting resolution:
