Hello

Lets start by removing the battery from the bottom of the laptop and then the power adapter / charger. Let the laptop be for 5 minutes, then hold down the power button for 15 seconds, then plug the laptop back to power, keep the battery out for now.

If the laptop power on and works, problem solved, you may reconnect the battery, if the problem comes back later in the future just repeat the above.

if this does not solve the problem then lets see...

When you turn on the laptop, do you get anything to flash on the screen? text for a short moment? Or is it completely silent? How about have you tried connecting a desktop computers display/monitor to the port on the side or on the back of the laptop - do you get picture on the desktop monitor? Is anything flashing on the screen? a Cursor?

Also Please take note of how many times the keys flash, it may indicate a error condition, please tell me the count, it will help in solving this issue.

    how many times do they blink? how many blinks until a pause?






    This document pertains to HP Notebook PCs with the HP Startup Support Environment.
    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. There is a pause and the pattern repeats continuously at the end of the series of blinks until the error is resolved.

    Okay, looking at the HP code list, that would be Code 1




    CPU not functionalThe computer processor (Blink code 1) has stopped functioning properly. Contact HP for assistance.

    Unfortunately, the cpu is inside the laptop, it can be removed and replaced, but I would not recommend you to do this yourself, as the CPU is NOT cheap, if the issues remain after replacement, you would have wasted and considerable amount of money on the replacement part.

    It would be best to take the laptop to a repairer or a shop, IF it is outside of warranty, the repairer can test another CPU on the laptop so you won't spend money on parts unless needed.

    It seems that theres a fairly good chance of getting this fixed under 200 us $, I would take it in to a shop.

    if you are in warranty contact hp, they won't charge you for the repair.



    Again outside of warranty, best thing for you is to take it in to a repairer.



    Let me know if you have any questions or if you need anything else.

On My Dv5-1125nr both the caps lock and num lock keeps blinking when i turn it on. It's wont boot at all. What kind of hardware problem is this?


First remove the battery and power cord for about a minute. Then plug back in and see if that helps. Otherwise please read the following:

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 LEDs blink 4 times Graphics Graphics controller not functional LEDs blink 5 times System board General system board failure LEDs blink 6 times BIOS BIOS authentication failure

My laptop when I power on, shows a blank black screen and the caps and num lock lights are blinking and the fan is running.


Your hard drive has probably gone bad and it does not have a bootable device to use on start-up.

HP DV6110us: 4 beeps, no boot


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.....
