LED near scroll and num locks keep blinking. Does not start often. Computer guy says moth board gone

HP pavilion DV4
Purchased from Singapore

Hi,
Try a Hard Reset as follows.
Shut down the notebook, unplug the AC Adapter and then remove the battery.  Hold  down the Power button for a full minute.  Re-insert the battery, plug in the AC Adapter and see if the notebook will start.
If this has not helped the issue, can you match the sequence of 'blinks' to those shown in the table below?
Regards,

  • HP Pavilion DV7-1428ca _ CAPS + NUM LOCK Continually Blinks + Will not Start up Black Screen

    Would appreciate any suggestions on the issue I am encountering.
    I have an HP Pavilion DV7-1428ca that was left powered on, so it went into Safe mode (screen goes blank). Once I came back to my Laptop hitting any key would take out of of the Safe mode however this time it did not. It remained with black screen irregardless of buttons pressed.
    Had booted and can hear the fan and hdd go for the 2secs then it stops to a Black Screen with the "CAPS + NUM LOCK" Continually Blinking. Tried to Hard Boot several times but the same thing re-occurs.
    It does not seem to be blinking in a series a code, just a steady blink (every sec) for both the CAPS + NUM Lock for as long as I leave it on. HP Site provides a chart from 1-6 series of blink codes which does not seem to apply to me.
    Being out of Warranty I am hesitant in bringing it to a local repair shop without trying any alternate trouble shooting first.
    Thanks

    Hi,
    First of all, shutdown the notebook, unplug the AC Adapter unplugged, remove the battery, and then hold down the Power button for a full minute.  Plug in the AC Adapter ( leave the battery out ) and see if the notebook will start.

  • HP Pavilion tx2500 - Caps Lock and Num Lock lights blink once

    I turn on my HP Pavilion tx2500 and I hear the fan spinning but nothing else happens.  The lights next to the Caps Lock and above the Num Lock keys blink (a repeating single blink).  According to some HP technical support documents I found online, the repeating single blink indicates a CPU problem.  My laptop is out of warranty and the $400 to send it to HP to have it fixed is practically the same price I paid for the laptop 2 years ago. 
    Do the blinking lights mean the CPU is fried?  And is there anything I can do to fix the laptop?
    Thanks,
    -Jeff
    This question was solved.
    View Solution.

    I have the same problem. I called HP they said the same thing. But, I am BIOS engineer myself and has worked with lot of motherboards, So I felt there is no point in sending a 399$ to find what happend and on top of that fixing charges.
    I noticed the problem started when I installed Win 7 Ultimate edition to the board and let tbe board Idle for a long time and it went into sleep mode and when I hit the button for resume it would not resume, the blinking started.
    I have seen the same thing happend to my friend laptop, luckily for him it recovered and he removed the Sleep Option. SO his laptop is shutdown or running in full power.
    I thought this is not coincidence, there is defenitely a bug in HW or SW that is causing it. remove battery. I replaced the memory and removed the cmos battery and left for a long time (short the battery terminals to discharge quickly). Then I rebooted the machine, Luckuly for me it went to windows, I tht of replacing the BIOS firmware, bcos they ahve some latest on by that time I had a visitor and I was talking to him the system went into sleep mode and will never recover. The system started blinking. I dont see this as a CPU problem.
    I still evaluating this. I will try to post my findings. I have aclip to read the BIOS chip but everytime i get different read. SO I am planning to remove the BIOS chip and put a socket so that I can play with the BIOS.

  • Caps, Scroll and Num Lock Notification - How to disable

    Hi,
    When i hit either my caps, scroll or num lock on my keyboard have this small notification popup and have problem disabling the function.
    How will i go about to disable this?

    C:\Program Files (x86)\Hewlett-Packard\Shared
    Find hpCaslNotification.exe and rename it.
    Then open task manager and kill this process.
    You have to rename the file, simplly killing won't work because hphotkeymonitor service runs it every time you press caps lock, scroll lock or num lock.

  • Pavilion DV5 1111ea CAPS lock and NUM lock continuously blinking

    I recently upgraded my dv5 pavilion 1111ea to windows 8.1
    Due to an issue with the OS, it doesn't resume from Hibernation, as described here.
    I held down the power button until the laptop swithched off.
    Once I tried to put it on again, it couldn't get to the BIOS screen, the CAPS lock AND NUM/SCROLL lock LEDs were blinking continuously, once every 3 seconds.
    No disk activity at all.
    I checked HP Notebook PCs - Blank Screen LED Error Codes but non corresponded to continuous blinking.
    I have a spare CPU which I removed from a discarded dv5, the CPU is exactly the same model with mine (AMD Turion x2 RM-72).
    I've troubleshooted by removing both RAMs and testing each individually in different ports, yet no solution.
    I'm suspecting the CPU because about a year after purchasing the PC, it began to overheat and hibernate automatically to prevent the CPU from burning. I had to underclock the CPU so, for over three and half year now, I've been running at 50% CPU speed. In total the laptop is 4.5 years old already.
    Please I need suggestions as to what to do. I don't have the required tools to replace the cpu myself.
    Thanks.

    I took my PC to a repairer and he claimed to have replaced the CPU with an AMD Sempron from his collection of scrap laptop CPUs.
    After about 3 months, the same problem has recurred.
    I opened it up, only to find my former CPU model inside!
    Whether the repairer had a spare Turion, or he only performed a trick to make my original CPU to work (and billed me for a replacement), I can't say for sure.
    Now I've purchased another CPU from eBay.
    Fixed it and...... got dissapointed again.
    Still blinking the CPU error code.
    From other posts I've come across here, I think HP/AMD combo is to blame for all these.

  • I uninstalled Firefox and now a setup wizard does not start when I re-download. 64 bit Windows 7

    My java stopped working, I reinstalled..Firefox still didn't recognize my java....I decided to reinstall Firefox and now when I download, Firefox will not open it's set up wizard it just extracts data and stops....grrrrrrrrr I run Windows 7 64bit Operating system

    Sorry you are having problems.
    Could it possibly be any security related software that is preventing this ?

    Make sure that you have an official copy of Firefox. Do a clean install BUT make sure you do not use any offer to remove personal data or you will destroy bookmarks and settings. If you have problems try to give the exact error messages so paste them into your reply of attach screen shots.
    Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
    '''Note:''' You might want to print these steps or view them in another browser.
    #Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
    #After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
    #Delete the Firefox installation folder, which is located in one of these locations, by default:
    #'''Windows:'''
    #*C:\Program Files\Mozilla Firefox
    #*C:\Program Files (x86)\Mozilla Firefox
    #Now, go ahead and reinstall Firefox:
    ##Double-click the downloaded installation file and go through the steps of the installation wizard.
    ##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
    <b>WARNING:</b> Do not run Firefox's uninstaller or use a third party remover as part of this process, because that could permanently delete your Firefox data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. <u>These are difficult to recover unless they have been backed up to an external device!</u>
    Lets get Firefox installed then deal with any Java problem.

    I use Ubuntu and just downloaded the newest Firefox browser. Then, I hit Extract, and it shows me a Firefox folder but nothing inside the folder can be clicked to to open the program.

    Also check that you meet the requirements for current Firefox versions.

  • Caps and Num lock blinking indefinitely

    Hey everyone.
    My brother just encountered the infamous startup error on his dv7-2045eo with blinking Caps and Num lock, but they are not blinking 1, 2, 3, 4, 5 or 6 times. They just continue to blink. What exactly does that mean? Other than that, it's just the regular startup error thing with black screen. We've tested the power supply, and it's just fine, so it shouldn't be a power issue.
     The hard drives are also okay.
    Any ideas?

    Follow the troubleshooting on this HP web document.

  • Blinking Caps Lock and Num Lock Keys Lit after spilling water Macbook Pro.

    What does it mean when the caps lock and Num lock key blink, after spilling liquid on a Macbook Pro? Does this mean that liquid is still present? Also, the white light by the latch was blinking. What does this all mean?

    Possible liquid damage.
    Immediately disconnect all peripherals, power cord & remove the battery. Turn the computer over with the lid partly open and the hinge facing upward to let the liquid drain. Do not flop it over and lay it flat - you want to separate it from the moisture. Place paper or cloth towels under the machine to sop up the mess.
    After the computer disgorges whatever you spilled on it, don't turn it on for 72 hours or longer. You want to computer to dry out completely before turning it on again.
    Some users here swear by hairdryers. Blow drying the innards may bake whatever was in the liquid onto delicate computer components. Better to let the computer air dry.
    Use plain tepid water to clean out the computer. If you spilled iced beverage more than likely this ice fried the hot motherboard.
    Sugary, acidic or milky drinks will almost always cause problems later on as the residue starts slowly corroding the computer innards.
    Swab down any sticky parts with distilled water or denatured alcohol.
    If none of the above works, you will need to take the computer to a repair shop. Apple Care does not cover liquid or food damage. Believe me, they can tell. So the old "my computer stopped working" line is not going to work.

  • DV4 flashing caps lock and num lock lights

    My laptop, an HP Pavilion DV4-2040US, has stopped booting up recently. The day before this problem come about I was using the laptop perfectly fine. I then went one day without using. When I turn on the laptop it booted up but nothing showed up on the screen. Then the CAPS LOCK and NUM LOCK lights started to blink on and off.
    I did some researching about the blinking lights and what they mean but I don't think mine is listed on there. It says the pattern will repeat a couple of times then shut off, but mine doesn't. The pattern is the CAPS LOCK and NUM LOCK both blink once every 3 seconds (about) and keeps blinking every 3 seconds forever. The only time they stop blinking is when I shut I down by holding the power button on the laptop.
    I've tried disconnecting everything and holding for 15 seconds and even tried holding it for 30 seconds and that still didn't fix the problem. I called HP support and the guy who I talked to told me it sounded like a motherboard issue, but he wasn't sure exactly and told me to ask here for help.
    If it matters, I can hear the fan turn on for about 2 seconds then stop. Also all the touch sensitive buttons light up too$

    Please, someone, anyone help me. I am having this exact same problem as we speak It happened after i put the laptop to sleep overnight. The LEDs for capslock and numlock blink consistently but slowly-approximatelt 2-3 seconds. When started up, i hear the fan come on for maybe a second or two and then comes off.I've tried all the mentioned solutions - i removed the battery for a while and put it back in-i tried the four arrows-i tried started up with AC adapted but without battery - and still no fix. What i am worried about is the documents and files on the laptop. Are they recoverable? Please help me on this someone. Please. Thank You.

  • Satellite C55-A and Ubuntu - Caps Lock and Num Lock key leds always off

    I use Ubuntu Desktop 14.04 and Mate Desktop and LightDM. My Toshiba Laptop is Satellite C55-A-1JH (PSCG6E) model.
    Cap Lock and Num Lock is working , but their leds always is off.
    I don't find any Linux driver in Toshiba support web site.How I solve this problem?

    Hi. Are you sure this is a Linux-issue? Please try this: reboot the unit and press F12 several times when the Toshiba logo is shown. When the boot menu is shown try Caps and Num lock again.
    Same issue or not?
