Use the following keystrokes to navigate the BIOS screens.

<F12> Menu

Press<F12>whentheDell™logoappearstoinitiateaone-time boot menu with a list of the valid boot devices for the system. Diagnostics and Enter Setup

options are also included in this menu. The devices listed on the boot menu depend on the bootable devices in the system. This menu is useful when you are

attempting to boot to a particular device or to bring up the diagnostics for the system. Using the boot menu does not make any changes to the boot order

stored in the BIOS.

Boot Menu

Your Tablet-PC features an enhanced one-time boot menu. The enhanced menu features the following improvements:

l Easier access — Access the menu by pressing <F12> during system boot.

l User prompting — The missing keystroke is now displayed on the BIOS splash screen.

l Added diagnostics options — The boot menu now includes two new options: BIOS Setup and Diagnostics.

Entering System Setup

Press <F2> to enter System Setup and change the user-definable settings. If you have trouble entering System Setup using this key, press <F2> when the

keyboard LEDs first flash.

Follow the on-screen instructions to view and/or change any settings. On each screen, the system setup options are listed at the left. To the right of each

option is the setting or value for that option. You can change settings that appear as white type on the screen. Options or values that you cannot change

(because they are determined by your Tablet-PC) appear less bright.

The upper-right corner of the screen displays help information for the currently highlighted option. The lower-right corner displays information about the

computer. System setup key functions are listed across the bottom of the screen.

The system setup screens display the current setup information and settings for your computer, such as:

l System configuration

l Boot order

l Boot (start-up) configuration

l Basic device configuration settings

LED Error Codes

Device Status LEDs

Device status LEDs are a good source for diagnosing common problems that may occur on your Tablet-PC.

Battery Status

If the computer is connected to an electrical outlet, the battery light operates as follows:

l Alternately blinking amber light and blue light — An unauthenticated or unsupported, non-Dell AC adapter is attached to your Tablet-PC.

l Alternately blinking amber light with steady blue light — Temporary battery failure with AC adapter present.

l Constantly blinking amber light — Fatal battery failure with AC adapter present.

l Light off — Battery in full charge mode with AC adapter present.

l Blue light on — Battery in charge mode with AC adapter present.

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.
