MY LIGHTS FOR CAPS LOCK AND NUM LOCK DO NOT SWITCH ON WHATS THE PROBLEM I HAVE A DV6625EM HP PAVILLION LAP TOP.

"The following table illustrates the meaning of blink codes used on some notebooks with EFI environment.
The blink or beep codes on your computer may have different meanings. When you contact HP for
support, the agent needs to know the model of your computer and may ask you about blinking LEDs
or beeping tones to help troubleshoot a startup problem.Meaning of Sample Blink Codes for some EFI Notebooks Number of Blinks or BeepsLocation of Blinking LEDsComponent Being CheckedError Condition

the number of times the num lock (1) and caps lock (A) blink will indicate where the failure is, but I would try removing and re-seating the RAM as a first fix!

Hello good day,sir
My compaq presario cq40..is powering on but blank on the screen and caps lock and num lock blingking only.I try ready so many time but everything are not meaning for me that's why i need your help,sir.please,give me some advice for power back.
Thank sir.

Try another AC Adapter with the battery taken out of the laptop. If the light still blinks then that means the motherboard is bad and would need to be replaced.

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 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

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.

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.....

Go to the following link, enter your model number (ie dv9074cl) then go to driver downloads and download the driver for quick launch buttons.
