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:

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

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

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

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

lBlue 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.

Keyboard Status LEDs

The light located above the function key F4 turns on when the numeric keypad is enabled.

The light located above the function key F5 turns on when the Scroll Lock function is enabled.

The light located on the caps lock key turns on when the Caps Lock function is enabled.

LED Error Codes

Turns on when you turn on the Tablet-PC and blinks when the Tablet-PC is in a power management mode.

Turns on when the Tablet-PC reads or writes data.

Turns on steadily or blinks to indicate battery charge status.

Turns on when wireless networking is enabled.

Turns on when a card with Bluetooth®wireless technology is enabled. To turn off only the Bluetooth

wireless technology function, right-click the icon in the system tray and select Disable Bluetooth Radio.
