    After the sequence of blinks or beeps, there is a pause for a few seconds, and the sequence is repeated (usually 3 or 4 times).

    Meaning of Sample Blink Codes for some EFI Notebooks <caption></caption> <tbody valign='top'>
    Number of Blinks or Beeps Location of Blinking LEDs Component Being Checked Error Condition
    Continuous glow Battery power LED Battery The AC adapter is attached and the battery is charging, but does not yet have sufficient charge to power the notebook.
    1 Caps Lock/Num Lock CPU CPU not functional
    2 Caps Lock/Num Lock BIOS BIOS corruption failure
    3 Caps Lock/Num Lock Memory Module error not functional
    4 Caps Lock/Num Lock Graphics Graphics controller not functional
    5 Caps Lock/Num Lock System board General system board failure
    6 Caps Lock/Num Lock BIOS BIOS authentication failure
    Continuous blink AC power adapter LED Power adapter Insufficient power
    Sorry if this is too late to help you but it may help others. This information can be found on HP's site by searching for 'blink codes'.
