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 LED (located on the left side of the computer, Figure 1) for a blinking amber or white pattern to determine failures listed in Table 1.
NOTE:
The blinking patterns consist of two sets of numbers represented by a group of Amber blinks, and then a group of White blinks.
First Group: The LED blinks with an Amber color one to nine times, followed by a brief pause with the LED off for one and a half seconds.
Second Group: The LED blinks with a White color one to nine times, followed by a longer pause before the next cycle starts again with the LED off for three seconds.
For example: For a No Memory Detected Error (2,3). The battery LED blinks two times with an Amber color, followed by a pause and then blinks three 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 shutdown when displaying the Diagnostic Error Codes.
Diagnostic Error Codes always supersede any other use of the LED. For instance, on Notebooks, battery codes for Low Battery or Battery Failure situations are not displayed when the Diagnostic Error Codes are being displayed.
