LEDs near Caps Lock and Number Lock keys blink when starting notebook

The LED lights near the Caps Lock and Num Lock keys will blink if an error is detected during the start up process. The LEDs will blink a number of times in a sequence and then stop. The number of blinks in the sequence indicates what component caused an error when it was being tested during start up.

If the LEDs stop blinking and the computer does not start, you can press the power button again to repeat the tests. Count the number of blinks, and use the chart to identify the error condition.

Knowing the number of blinks is helpful when you contact an HP support agent for technical help.

Caps Lock/Num Lock LED	Component Tested	Error Condition
LEDs blink 1 time	CPU	CPU not functional
LEDs blink 2 times	BIOS	BIOS corruption failure
LEDs blink 3 times	Memory	Module error not functional
