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.

Hi,

First you need to determine how many blinks you are getting when you try to power on the laptop.
Check the blinking codes below and reason behind that for HP Compaq laptops

Blinking battery power LED Battery Insufficient charge on the battery
Blink: 1 - Caps Lock/Num Lock - CPU CPU not functional
Blink: 2 - Caps Lock/Num Lock - BIOS BIOS corruption failure
Blink: 3 - Caps Lock/Num Lock - Memory Module error not functional
Blink: 4 - Caps Lock/Num Lock - Graphics Graphics controller not functional
Blink: 5 - Caps Lock/Num Lock - System board General system board failure
Blink: 6 - Caps Lock/Num Lock - BIOS BIOS authentication failure

Plz get back so I can suggest you the steps to resolve the issue.

First you need to determine how many blinks you are getting when you try to power on the laptop. Check the blinking codes below and reason behind that for HP Compaq laptops Blinking battery power LED Battery Insufficient charge on the battery Blink: 1 - Caps Lock/Num Lock - CPU CPU not functional Blink: 2 - Caps Lock/Num Lock - BIOS BIOS corruption failure Blink: 3 - Caps Lock/Num Lock - Memory Module error not functional Blink: 4 - Caps Lock/Num Lock - Graphics Graphics controller not functional Blink: 5 - Caps Lock/Num Lock - System board General system board failure Blink: 6 - Caps Lock/Num Lock - BIOS BIOS authentication failure Well Check for the below link it will provide you the steps which you need to perform to isolate the cause so that we can determine which hardware of the laptop is causing this issue. http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01443366&cc=us&lc=en&dlc=en You need to first Remove the memory module (RAM)- Try to power on the laptop ? then again reset it and try to power on. Check whether it is coming on or not. try the same procedure with Hard drive. If laptop is getting power on after removing one of the device then we can be sure that that particular device is faulty and we can change that then? Let me know if you find any difficulties doing this.. I hope this will help you to get it work. Plz vote for me..Dreamkam

besides the beeps which indicate a motherboard timing issue. There should be LED blinking codes given on the front LEDs. I will include the blink codes below, but lets try to at least get the system up and running. First, I would like you to remove the RAM sticks from the laptop and just reseat one stick back in the machine. Try to boot with that one stick, if it does not, try the other alone. There have been issues when reseating the ram or re-installing it have temp. fixed the issue. If it does reboot, go to the HP support site, put in your model number of your laptop and download and install an updated BIOS. Below are the blink codes that may narrow down the problem.....
