LED Error Codes
Device Status LEDs
Device status LEDs are a good source for diagnosing common problems that may occur on your computer.
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 computer.
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 three 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 green lights located above the keyboard indicate the following:
LED Error Codes
