When you experience a situation in which the computer does not start at all, or if it does turn on (lights turn on and fans are spinning) but the computer does not show any image, look at the Battery Charge/Status LED (located on the front of the computer, Figure 1 ) for a blinking amber/white pattern to determine failures listed in Table 1 . Figure 1: Battery Charge and Status LED Location Note: The blinking patterns consist of 2 sets of numbers being represented by a group of Amber blinks and then a group of White blinks. First Group: The LED blinks with an Amber color 1 to 9 times, followed by a brief pause with the LED off for 1.5 seconds. Second Group: The LED blinks with a White color 1 to 9 times, followed by a longer pause before the next cycle starts again with the LED off for 3 seconds. For example: For a No Memory Detected Error (2,3). The battery LED blinks 2 times with an Amber color, followed by a pause and then blinks 3 times with a White color. The battery LED will pause for 3 seconds before the next cycle repeats itself again. Each LED blink takes 0.5 seconds. The computer will not shut down when displaying the Diagnostic Error Codes. Diagnostic Error Codes will always supersede any other use of the LED. For instance, on Notebooks, battery codes for Low Battery or Battery Failure situations will not be displayed when the Diagnostic Error Codes are being displayed.
