This document pertains to HP Notebook PCs with the HP Unified Extensible Firmware Interface (UEFI) beginning in late-2008.
On startup, you may see a blank screen. If the diagnostic utilities detect a specific problem with hardware components, the fan turns on, but the screen remains blank. To help identify the cause of the problem, various LED lights on the keyboard blink a series of codes.
The diagnostic utilities use the LEDs near the Num Lock or Caps Lock keys to blink a series of error codes. At the end of the series the blinking stops. The pattern of blinks will occur any time you attempt to start the computer until the error is resolved.
Battery power LED blinks
The Battery power LED indicates the condition of the power supply. When starting the computer, or when the computer is in operation, use the chart to identify the power condition.
Battery Power LED
Component Tested
Error Condition
Battery power LED off, and Caps Lock/Num Lock off
Battery or AC Adapter
AC adapter not connected or failure
Battery low charge or failure
Battery power LED blinking
Battery
Insufficient charge on the battery
When new computer is used for first time, the white LED light for the AC power connector blinks.
Battery is still in "Shipping Mode", the light continues to blink even when AC power is connected.
To resolve, turn off notebook, connect AC power and allow battery to charge for at least 30 minutes, then start computer.
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.
