G72-B61NR Laptop screen black;Num & Caps locks blinks; Hard Drive works fine

Hello everyone! I would like to get a solution to a problem I've been having with my laptop; if no solution, then a reason for my problem would be great. My laptop has recently stopped booting up correctly. Basically the screen is black and will not turn on. The NUM LOCK and CAPS LOCK LED lights flash a number of times before the computer shuts down. When I turn on the computer I can hear the fan and the hard drive running but no screen. I have been able to take out the hard drive from the laptop in hopes of salvaging important documents and I was able to do so by connecting it to a desktop. Is there anyway to fix my screen and save my laptop? Thank you in advance for any help.

Hello soTERRAble, welcome to the HP Forums.
I see that you have a blank display with your notebook. I will try to help you with this.
From what you describe this could be indicating that something in the notebook is not working correctly, right now I wouldn't be able to tell you what but can provide you two documents that might be able to identify what.
Computer Does Not Start and the LEDs Blink or the Computer Beeps - this document may be able to assist you with the flashing LEDs your getting when trying to start the notebook. Watch to see if you can identify an error pattern. If you can compare it to the table in that document. This will provide an idea to what may be failing.
Troubleshooting Black Screen Displays with No Error Messages During Startup or Boot - if the above document could not direct you to something failing, then follow this one.
Let me know where the above documents lead you.
Thank you for posting on the HP forums.

  • Num/Cap lock blinking and computer screen not starting

    ok. i have a HP pavilion entertainment pc dv7 notebook.
    1)    For the last 3 weeks my screen would turn off randomly. maybe once every other day or so on.  The computer would stay on and my ligths on the keyboard,( VOL bar, Multimedia buttons, Wifi button, Mute button, Caps lock and Num lock) .Only thing that would turn off is my Monitor. Sometimes when it turns off my speakers would make a status sound across the sound bar. But i can be on my computer for hours, or even leave my computer on for days with the screen open and it wont do anything.
    2)   then for that last few days i notice when i turn on my computer everything would turn on EXCEPT THE MONITOR. then i hold down the power button and turn it back on and it starts up fine.
    3)  Then yesterday when i tried turning it on. Same thing monitor wouldnt turn on but my NUM/Caps lock would blink. So again i would turn the laptop off , turn it back on and now its up and running
    I really rely on my computer so i was considering taking it to a local tech but i wanna know the issue so he doesnt give me some kinda Jive turkey story. I would just start rening a computer from Aarons rent but  dont think there computers are any good for my gaming. Starcraft 2, league of legends ecct.

    Hi,
    Please try a hard reset and see if it works.
    1. Power off your laptop
    2. Remove the a/c adapter, battery and everything that is attached to your laptop.
    3. Hold the 'POWER 'button down on your laptop for about 10 seconds.
    4. Plug in the a/c power supply (without battery) and power on.
     Please check the following link for more information:

  • Pavilion DV6, Black Screen and 3 Caps Lock Blink

    HI,
    I have an Hp Pavilion DV6 and I am getting the 3 blinks on the caps lock. When I turn on the PC it starts up, the caps lock blinks 3 times and the screen is just black. I have already tested the memory sticks, drain the battery, and hooking it up to an external monitor.  Nothing shows on the other monitor and it just remains black. Please help!

    Hi @shmurray,
    Welcome to the HP Support Forums!
    I understand you are getting a blink pattern on the Caps lock LED, when you turn on the notebook. I am happy to help you with this.
    I am including the page on the error codes for your reference: Blank Screen LED Error Codes
    From that document the pattern you are getting indicates a memory problem. You said that you have tested the memory. What exactly did you try?
    The document suggests reseating the RAM or trying a new set of RAM and then restarting the notebook. If you are still getting a memory problem after trying both of those things, ie a 3 blink code again, then it would likely suggest that there is a problem with the motherboard itself, either with the memory slot or one of the controllers related to memory.
    In that case I would suggest contacting the technical phone support number at 800-474-6836. If you live outside the US/Canada Region, please click the link below to get the support number for your region.
    http://www8.hp.com/us/en/contact-hp/ww-phone-assist.html
    If however reseating the memory or replacing it leads to a different error code or message please let me know, Although in that case the following may be helpful if you still have a blank screen.

    Here are some other sources I found that may be helpful to you.

  • Blanc screen at startup / Caps lock blinking 3 times HP Pavilion dv7

    Hello,
    Hope someone can help me out.
    First we received SMART warnings but we were still able to start up Windows in safe mode (took about 15 minutes and the laptop was getting warm). We took the HDD out and connected it via USB to an other PC. We could not read the content and needed to format the disk... did NOT do that. We kept the HDD "origional".
    We bought an Samsung EVO 850 250 Gb SSD for the laptop... as replacement for the corrupted one and to upgrade the system. The main battery was removed, adaptor was not plugged in for a couple of days. Today we received the new SSD and installed it... but... the laptop is not starting up anymore! The screen stays completely blank. The F12 is lighting orange and the CAPS LOCK is blinking 3 times. 
    We've read several articles on forums and tried various suggestions:
    - Changed the BIOS battery;
    - Several "hard resets":
      . removing adaptor and main battery and pushed the power button for 15 seconds;
      . Windows, B and power button at startup;
      . pressing F8 while booting;
    - build the original HDD back in;
    - removed the memory and tried all banks in all slots;
    - connected external monitor;
    - startup via bootable USB stick;
    - cleaned the cooler fans (with compressed air spray);
    - tried an other AC adaptor;
    - tried without the main battery;
    - tried to startup with no memory, no BIOS battery and no HDD installed.
    Doesn't matter what we tried... after trying every suggestion the screen stays blank and the CAPS LOCK is still blinking 3 times repeatedly.
    Anyone any idea what ik can try further? In my perception the BIOS is not loading at all?!?!
    Looking forward to read your suggestions! Thanks in advance
    Best regards,

    Hi there @BerDie13 
    Welcome to the HP Support Forums! It is a great place to find the help you need, both from other users, HP experts and other support personnel.
    I understand that you are getting a repeating pattern of three flashes from the LEDs. I am happy to help with this.
    Check out this page under the section for flashing LEDs. In that you will find that three LED flashes indicates a memory problem.
    Computer does not start and the LEDs blink or the computer beeps
    Use the instructions on how to deal with that. I am a bit concerned that you have both a hard drive failure and a memory issue, but it is possible that the memory could have been disturbed when you were working with the hard drive. If the reseating of the memory does not help, I would try the memory in different slots and if you have more than one memory module try them one at a time in both slots to isolate which is the problem child. The worst case would be multiple bad memory modules and a defective set of sockets on the board.
    Let me know what you find.

  • Hp pavilion g4 1104dx display white screen and caps lock blink twice

    Hi i recently used my hp laptop screen to test another laptop acer aspire 5517. After the test i reconnected back the cable only to power it on a white screen appeared with caps lock blink twice. I thought the problem might be screen shot so i decided to connect to external monitor but still no signal on external monitor even after pressing fn+f4. What might be the problem thanks.

    Hi there , Thank you for visiting the HP Support Forums and Welcome! This is a great site to get answers and ask questions. I understand you are having an issue with your Notebook. You had stated that you receive a White Screen and the Caps Lock are blinking twice. Please be very careful when it comes to blink patterns as sometimes there can be a pause between the blinking.   Before you start troubleshooting, please note remove any and all USB devices. Disconnect all non-essential devices, as these could cause some issues. Here is the first document I found called Performing a Hard Reset or Forced Reset. If that does not work, please follow Computer Does Not Start (Windows 8). The last document I have for you that may help is called Computer does not start and the LEDs blink or the computer beeps. Please follow these provided troubleshooting steps, re-post and let me know how everything went. Thank you! Have a great day!

  • Caps lock blink. laptop gets black screen

    Hi! I'm getting a blank screen with the Caps Lock light blinking. I tried the troubleshooting forums where it tells you to put the ram stick in the outer slot. However mine is already in the outer slot and the same problem persists. Please help.

    Will I lose my HDD data? Got a lot of imp stuff there.You will have to take out the HDD and use a external USB HDD adapter and access the HDD and copy your data off. That is the only way you can get the data back. Or send it to HP fix without the HDD and when they fix the board you can reattach the HDD and bootup and see if it can still recover the HDD and get yourself data back.

  • Black screen with caps lock blinking

    I was using my laptop and it was turned on and after some other work I wanted to use my laptop, the screen was black and caps lock was blinkingI turned it off manualy and it was again doing this. Caps Lock blinks 2 times after a pause of 4 seconds continously.
    I tried reset and other things but its not showing anything. 

    Hi Nayj424,
    Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your Compaq Presario CQ62-102TX Notebook and getting a blank or black screen on startup. Try performing a hard reset. When performing a hard reset please note remove any and all USB devices, and remove memory cards from the card reader slot. Disconnect all non-essential devices. If that does not help try to turn on the computer you start to press F11 repeatedly till the menu opens. You can do a system restore.
    Hope this is helpful.

  • Dv6 Notebook "Black Screen" following "Windows Blue Screen" error message. Caps Lock blinking!

    I have a HP DV6 notebook. I left my computer on overnight and the next morning I woke up to find a Windows Blue Screen error message. It said to restart my computer. I was in a rush so I just closed the lid. When I returned I opened the lid and the screen was black. I pressed the power button to restart it and I haven't been able to restart it since. I now have a power light, a black screen and the CAPS LOCK light is blinking twice then a pause! Please help!

    Hi btgclark,
    I understand that you are having an issue with turning on your notebook and the CAPS LOCK light blinks twice and then pauses. The following document 'Computer Does Not Start and the LEDs Blink or the Computer Beeps' will walk you through the steps that you need to follow. For your error code, it means that the BIOS has a corruption failure. This document will walk you through the necessary steps to get this resolved.
    If for some reason this document does not resolve the issue please provide me with the model number to your notebook. I have included a document 'How Do I Find My Model Number or Product Number?'
    Please let me know how this works out for you, thank you.

  • Caps lock blink 5 times on Compaq 615 laptop, but screen doesn't come on.

    My Compaq 615 laptop screen doesn't come on, instead it blinks capslock 5 times. What shlould I do?
    It has an AMD Athlon X2 processor, with Radeon 3200 graphics.
    I didn't install any new software or hardware recently. All I did was work with the system at night, shut it down, and when I turned it on the following morning, the screen refused to come up, but the caps lock blinks 5 times.

    Sorry to hear that. Please refer to the Blank Screen LED Error Codes document from HP Support. It sounds like a "General system board failure." The explanation says to contact HP for assistance. The motherboard might need to be replaced, and you will probably require the assistance of a technician to fix the problem.

    Hello SuperMario1,
    Thanks for your response.
    The last thing i did, remove CMOS battery and after a few minutes i plugged it.
    Then connect AC power adapter and press power button.
    Laptop starts but gives a error message
    "The CMOS checksum is invalid, The BIOS will be reset to the default configuration and will be rebooted."
    Finally laptop start normally. It works fine ...
    But same problem when i restart
    "blank screen caps lock blink 2 times every 3/4 sec"
    So finally
    1. remove CMOS battery and after a few minutes i plugged it again
    2. connect AC power adapter and press power button
    3. laptops starts normally (with a error msg same as previous)
    4. Upgrade bios to F.29(previously i had F.24)
    5. Everythings works fine (restart/shutdown have no effect)

  • Num + caps lock on MBP 17"

    I reinitialized a MBP from the recovery DVD.
    At the very beginning of the process num + caps lock lighted up and remained so through the complete installation. I did not touch them before and during the installation
    After the installation war finishet, I found out the both functions would work in reverse mode, meaning:
    num is on = the keyboard works normally
    num is off = I can enter the numbers only
    caps lock is on = keyboard works the normal way
    caps loc is of = only uppercase characters show when typing
    Maybe this is an old question.
    The mbp had been initialized after purchase by its first owner (from which I purchased it) and it worked normally when I checked it before purchasing it.
    Any idea?

    Have you tried resetting your PRAM (KB) or the PMU (KB)?
