Battery Charge and Health 

To check the battery charge, press and release the status button on the battery charge gauge to illuminate the charge-level lights. Each light represents 

approximately 20 percent of the total battery charge. For example, if four lights are on, the battery has 80 percent of its charge remaining. If no lights appear, 

the battery has no charge. 

To check the battery health using the charge gauge, press and hold the status button on the battery charge gauge for at least 3 seconds. If no lights appear, 

the battery is in good condition and more than 80 percent of its original charge capacity remains. Each light represents incremental degradation. If five lights 

appear, less than 60 percent of the charge capacity remains, and you should consider replacing the battery.

The 

Digitizer Options

 tab is used for the following: 

l

Input mode selection 

l

Touch tuning 

l

Launching diagnostics 

l

Restoring default settings 

Input Mode 

The N-trig applet has 4 operating modes: 

l

Pen Only

—

 In this mode, the stylus is the only device that can be used as the input device with the N-trig digitizer. Changing from Pen Only mode to 

any other mode is done by clicking with an active input device on the N-trig Applet icon in the system tray. When the applet is open, select desired mode 

and press OK. 

l

Touch Only

—

 In Touch Only mode, a single finger is the only input device that can be used with the N-trig digitizer. Using the stylus is not possible. It is 

important to note that only a single hand contact is allowed with the digitizer for proper execution. Changing Touch Only mode into any other mode is 

done by tapping the N-trig Applet icon in System Tray using a finger or other active input device and choosing the desired mode. Press OK to confirm. 

l

Auto Mode

—

 The N-Trig digitizer is capable of detecting a stylus as well as finger touch. The purpose of Auto Mode is to allow the user intuitive toggling 

between the Pen Only or Touch Only modes. The default input device for Auto Mode is the stylus as long as it is in range of the tablet screen (hovering 

in proximity or in contact). A basic principle in Auto Mode is that stylus detection in the digitizer proximity would turn the digitizer into Pen Only mode as 

an overriding priority. A double-tap finger gesture on the screen (similar in style to a mouse double-click) will switch the digitizer from Pen Only mode to 

Touch Only mode. The system will remain in Touch Only mode as long as the stylus is out of range. Once the stylus is detected in range the system will 

automatically switch to Pen Only mode. 

l

Dual Mode (Vista Only)

—

 Dual Mode is a unique operational mode that is functional only while using the Microsoft Vista operating system. In this 

mode, the OS switches automatically between the available pointing device according to its internal priority and attributes. 

Touch Tuning 

If you believe that the Tablet-PC's finger detection function is not working properly, a recalibration of the touch feature may be in order. To accomplish this click 

the 

Reset

 button and then follow the on-screen prompts. 

A message indicating success or failure appears once the reset routine completes. If the result is failure, try running the diagnostics.  

Diagnostics 

Running the diagnostics will help determine the functionality of the digitizer. Start by clicking the 

Troubleshoot

 button. Pressing the 

Self Test

 button on the 

subsequent pop-up window starts the diagnostics. 

After the test is complete, the results are displayed as illustrated below. 

CAUTION: 

Do NOT touch the screen while touch reset is in progress. 

Use this table to define the result codes.

Multi-Touch Gestures Feature 

Dell™ Latitude™ XT2 Service Manual 

Gestures 

Gestures are expressions made while touching the screen of your Tablet PC with two fingers. They are interpreted as user commands to the operating system 

or active application software. When the operating system recognizes a gesture, an icon confirming the gesture appears on the screen. This multi-touch 

update includes three gestures: a scroll gesture, a zoom gesture, and a two-finger double-tap gesture. Gesture features and descriptive icons shown herein 

are sourced by N-trig. 

Scroll Gesture 

Placing two fingers on the screen and moving them horizontally or vertically generates scrolling in the direction of movement: right, left, up, or down. 

Zoom Gesture 

Touching the screen with two fingers and moving them together or apart generates a zoom-in or zoom-out command to the screen. 

Two-Fingers Double-Tap Gesture 

Tapping the screen twice with two fingers sends an operating system command that you can configure. It can be used to perform actions, such as turning the 

display off and disabling touch gestures (default), or run an executable program, such as one that opens Internet Explorer. 

Sensitivity Setup 

To adjust the sensitivity for the two-finger gestures, double-click the N-trig icon ( 

 ) in the system tray, and tap the Multi-Touch Gestures tab. Set the sliders 

for each gesture as desired. 

About Tab 

Dell™ Latitude™ XT2 Service Manual 

The 

About

 tab is used to find information such as the driver version and firmware revision numbers. The firmware revision number can also be obtained by 

hovering your pointer over the N-trig Tablet Settings icon in the system tray.

Calibrating the Pen

Troubleshooting

Your Tablet-PC uses a specifically designed electrostatic pen or 

stylus

 for use in tablet PC mode. Instead of relying on battery power, the energy source for the 

stylus is magnetic energy produced by the excitation coil built into the digitizer itself. The signal from the coil is picked up by the stylus and triggers the stylus 

to transmit an electric field. 

The transmitted electric field is sensed by a matrix of conductive lines, accurate stylus position determined using the low amplitude signals received on the 

vertical and horizontal conductors, and an appropriate signal is transferred to the digitizer's on-board processor.  

Tips come in two colors/types, blue and black. The blue tips are designed for a "softer" writing feel. The black tips present a "harder" writing feel. The system 

ships with a total of 5 (3 blue and two black) tips. These tips are easily replaced by using the pen-tip removal tool which looks similar to an oversized pair of 

tweezers. This tool also ships with the Tablet-PC. 

Calibrating the Pen 

The pen can function at the default calibration or at a calibration set by you or by another user. It is recommended that you use the pen only while it is 

calibrated to your personal calibration settings. Calibration optimizes pen performance for each user. 

To calibrate the pen: 

1.

Open 

QuickSet

. 

2.

Click 

System

®

Tablet Settings

. 

3.

On the 

Dell Tablet Settings

 window, click 

Pen & Input

 then click 

Calibrate

. 

4.

Follow the instructions on the screen. The calibration markers are displayed on the screen as plus signs (+). Tap the pen in the exact center of each of 

the calibration markers. 

Troubleshooting 

The pen is the first component to be investigated in the event of a suspected problem with the digitizer. Verify the tip is in good shape (free of chips, excessive 

wear, etc.) by closely examining it. If there is any doubt, you should change out the tip with a new one or one that is known to be in good condition. 

You should also verify that the touch capabilities are not affected. Switch to touch mode and see if the problem still exists. If there are no symptoms present 

while in touch mode, the pen tip is the most likely suspect. If the problem does persist in touch mode you should run diagnostics and take the necessary steps 

depending on the results. 

NOTE:

 In the event of a suspected digitizer failure, the pen tip should be examined. If the tip is damaged it needs to be replaced. This will oftentimes 

remedy to problem with the digitizer. 

NOTE:

 Be sure to calibrate the pen for use in both portrait and landscape display orientations.
