Num Lock and Caps Lock flashes twice

Hi, I have a problem with a laptop HP DV4-2045dx who is now 5 days out of warranty.

He has decided to no longer start, and never shows anything on the screen.  When turned on, the power light, fan and light volume bar upwards and after about 10 seconds, the plugs and caps lock Num lock light flashing 2 x and make a break before repeating many times.

I tried to remove the HDD, memory, reinstalling NIC. I have made the power off the power, remove the battery and holding the button works / stop 20 seconds without change. I also removed the CMOS battery for 30 minutes.  I left the laptop on it during the night with no luck he restore the bios, I also left unplugged without battery for several hours.

HPs site tells me that the BIOS is damaged, based on the lights flash.

So how you fix a corrupted bios when the laptop does not start? Should it be sent repair, and whether someone has an estimate for this repair?  Any help would be greatly appreciated.

* EDIT * I know that the HARD drive is bad, the laptop stopped booting (it would be only goto repair windows and my HARD drive diagnostic tool there not this day.  After a few other boot attempts from this start white screen)

It finally sets the strangest way... removed from the memory and jumped into a 512MB stick older... booted up.  Shut donw and put the 2x2gb sticks in and functioning again.

Running memtest now to see if it was bad or not.  If not... its waiting just for a recovery by post media.

  • Envy 15 t-J100: generates no video, Caps Lock flashes twice

    Good afternoon! I connect to a Wi - Fi using the router QSS button which is used to allow access without entering the network password, but when I pressed the button that my laptop has a blue screen (this error screen windows 8.1 with a sad guy), he held the button for a few seconds until stop you it , it had already happened other times I tried to connect using the QSS routers function, but this time round it has no video, the Caps Lock LED will blink twice at an interval of 5 seconds, then blinks twice and so on several occasions.
    I did some research and saw two flashes mean problem with BIOS.
    I bought the laptop to do Paraguay 11 months, the store gave me the one year warranty, but as I live in the Brazil I would really solve without making the warranty.
    I'm so computer technician if you have a procedure that can be like to explain to me if I can solve

    The model of laptop is an Envy 15 t-J100, processor Intel core i7, 8 GB of memory, 1 t + HD 24 GB SSD. It was never opened and never been formatted, all partitions that comes standard, the only thing I did was to reduce the system partitions to create another partition to store data.
    Some already appreciate your help...

    Good afternoon!
    I checked the warranty book and it was over.
    Then, I managed to solve the problem as follows... I opened the computer laptop, unplugged the HD, the network card and the SSD, cleaned the contacts of memories using an eraser, clean contact and unsightly brush, I called him just for ram connected (not HD, SSD card and network) and the laptop has video obviously did not start because he was without the HD, then hung up and went to connect devices in the following order and first test the SSD then the network card and the HD. And ready! The laptop started normally.
    I realized shortly after starting it was installing updates from Windows update. My theory for this is that at the time when I pressed the button the laptop QSS was to install a major update of Windows and restart unexpectedly at the Blue error screen.
    Thank God could solve, thank you for your help!

  • continual caps and num lock flashing & wireless on.

    HP g7-1150us

    Problem started after the replacement of the touch mouse/Cushion cover. He did initially not power on. I have it plugged in AC, in case the battery is dead and I tried again.

    Then he started the continuous flashing. I tried the hard reset, hit ESC to put under tension, but had no luck.

    The hard drive turns, but not looking not.

    I removed the new Panel and put the old one back in and there was no change.

    I believe I got all cables & connectors properly.

    I thought I can have killed one of the sticks of memory, so I tried to install just one.

    I get not one of the 6 sequences different blink, it flashes slowly about 1/sec continuously.

    My wife is going back home tomorrow and I'm in trouble!

    Help appreciated,

    Hello bobarry,

    I saw your post about problems with the phone on/off do not. If there is no model to the flashing light then there is nothing to indicate which causes the error. This is Service and Maintenance Guide for your model and starting on page 66, there are instructions for removal and replacement of the TouchPad. It might help to determine if there is a connection problem. If control connections does not help then you will have some take a look at the laptop. You can reach HP Total Care at 1-800-474-6836 in North America or Start here if you live outside of North America.

    Thank you

  • Pavilion dv6t 7000: failure of the BIOS (Caps lock flashes twice a secone)

    My laptop model number is Pavilion dv6t 7000. In recent days, he had a problem. When I turned off my laptop and put it off, the next day I find that is not starting. A black screen, caps lock shift is blicking twice and f12 key is red (WIFI). Nothigs happen. Then, I searched and came to know that it is the failure of the bios. Then I tried some way and nothings worked. ATLAST when I remove the cmos battery it set again after 2 or 1 minute its starts fine. Then againg I turn off the computer and its power day following again the same problem. I was to solve this problem by removing cmos battery and put it again for 4 or 5 days. But today this tip does not work. I tried so many method like (Windows key + B), (byholding down the power button for 1 minute), (Flash UEFI) etc. to solve the problem of failure of the bios, nothing worked at all. What is the problem?  Is this really a failure of the bios? How can solve this problem? What is a dangerous problem? There the chances that my laptop is completely exhausted?

  • My Satellite M70 no longer works, and caps button flashes

    My problem was explained in the title. I just want to know if there is a problem or not. I work on Linux and windows XP, but the problem can happen in the BIOS.
    Thank you, Vivien.
    If you need more information, please ask me :)
    PS: it's the Satellite M70, and I changed the RAM

    Hello

    I'm afraid that you have to be a little more specific than one that's a little wave... but now that you mention that you have changed the RAM maybe this is related to the question of Mr. is your RAM speed appropriate for your laptop? (Example to 400 or 533 MHz, regardless of the speed is indicated for your product). Because if your RAM is at the wrong speed, or at a higher speed (for example, 667 MHz, which happened with me) the computer can crash/blue screen/go crazy.

    In fact, now I remember that my flash CAPS LOCK button too, because of the bad RAM or Aries do not correctly inserted. I recommend to check the speed of your RAM and make sure that you have inserted the right type, RAM speed and you have inserted it correctly

    I hope this helps.

  • White screen on Boot and CAPS lock and NUM lock LED blinking on HP Pavilion dv - 6 portable 1210sa

    Hello

    I'm on HP Pavilion dv6 - 1210sa laptop with Windows vista Home Premium (service Pack2). It's the operating system, which is that the laptop came with when I bought in 2010 and later service pack 2 was installed using windows update. I can confirm that my laptop is up-to-date with updates of windows and hp installed periodically. My problem is the following:

    Everytime I turn on my laptop, I can hear the noise from the cooling fan and the led power and feather touch volume buttons and a wi - fi light up. However, the screen remains blank and the CAPS lock and NUM lock Dungeon LED flashing with three second gap between two flashes. They Flash together and blink only once in a single cycle. It keeps flashing even after leaving it for 10 minutes. I have to perform the hard reset several times before I can get it started. This problem started a few months ago with the frequency of the problem more and more. It has now reached a point where I encounter this problem on every start and even after the awakening of the laptop computer from standby or hibernation.

    I know that the flashing of the LEDs is typical diagnoses, but I was unable to understand the real problem. I know the screen works because I tested using an external monitor to work. It should not be the battery (even if it's crap to maintain charge) I tried to restart the laptop with just AC adapter connected (and battery removed) after having done a hard reset and still, the situation did not improve.

    Could someone please tell me what is the problem and what are my options? Think you that formatting my c: / and re - install the OS will solve the problem?

    Thank you.

    Please come back to me

    As long as you keep your files backed up on the outside, it is to you how you want to proceed. First question, however, is you are in warranty or not? If you are in warranty, Yes, call telephone support and will take care to have it sent repair.

    If you are no longer in warranty, however, that the repair can be expensive. You could certainly call for an exact quote, but according to the availability of the room, it might be around $200 and for an out of warranty repair. Money would probably be much more effective if they are presented to a new computer.

    HP Total Care 1-800-474-6836

    BUT, if you're still able to get the it to power (after trying it several times) and you're OK with the disadvantage, it would be nice to hold off on buying a new computer until it failed completely. I hate this word like that but I want to be realistic with you. I'm sorry that you are having this problem. As I said though, your files are the priority. Keep all your documents and photos and other precious files saved on an external hard drive or flash drive. Let me know if you have any other questions

  • Satellite C660 - keyboard does not work but the Num and caps lock shift are on

    I have a Satellite C660 which was working fine this morning. When I came home from work and he turned, the keyboard does not work and therefore can not enter my login information.
    The Num and caps lock shift are turned on.

    Any ideas on how to solve this problem?

    Hello

    You are able to disable the CapsLock and NumLock?
    You can access the BIOS by pressing F2 by turning on the device?

    If this does not work, I would recommend checking an external USB keyboard.
    If the USB keyboard would be functions, then this means that the internal keyboard is defective and must be replaced.

  • HP envy 15 t-j100: screen went white and caps lock flashing after update bios!

    Update my bios to the latest version via app HP support and after it restarted the screen are empty and the caps lock flashing! What can I do about it?

    Thank you for visiting @omidmiri.

    Here on the Forums of HP's Support, you have access to many members of the community with solutions and suggestions to help. I understand that you have a problem with a black screen and the Caps Lock LED flashes after a BIOS update.

    The led near the caps lock shift keys and numlock blinks if a fault is detected during the boot process. The LEDs flash multiple times in a sequence and then stops.

    Please try to manually perform a BIOS recovery, as follows:

    1. Turn off the computer.

    2. Plug the laptop using the power adapter.

    3. When the computer is always off:

      1. Press on and hold the Windows key and the B key at the same time and then press in and hold the power button on the laptop for a second.

      2. Release the power button and the keys.

    By following these steps, the BIOS will reach the EFI partition in order to recover the BIOS to the latest known version of the BIOS from the hard drive.

    If this does not work, please use the above original document to calculate the number of flashes and troubleshoot accordingly.

  • Caps lock and num lock keys lights don't light up

    Hello

    My caps lock and num lock keys lights don't light up when I turn the plugs or NumLock on, I recently contacted Microsoft Tech support, they told me to contact my HP manufacturing and it's a laptop, they did ' t really gives me a lot of support, so I'm here without you people asking how to solve this problem.

    Thank you
    Marco

    Hello Marco818,

    Thank you for your message.  Microsoft was right to put you in touch with the manufacturer of your.  The keyboard will fall under the material, so only they can fix or diagnose what the problem.  It could be something as simple as a bad supply or burnt cable bulb.  Anyway, that falls under HP support.

    See you soon

  • G6 caps lock flashes continuously, nothing on the screen

    Hi, I have a HP g6-1325sa had a problem which had to replace the fan.

    However since then nothing appears on the screen F12 has an orange light and the caps lock continuously flashes every 2-3 seconds. This isn't a blinking code it does this constantly.
    So far, I have tried blocking the vents and leaving the laptop that works for more than an hour, as I've heard can be caused by dry solder joints. I have also tried to replace the motherboard and twice managed to get a cursor blinking on the screen but niether of those moments a normal startup is possible that the HARD drive has been disconnected on both of these occasions, the first time that it happened, I had just disconnected power and battery and power and hold for 30 seconds I'm guessing it's a cmos reset.

    the only cause I can think is that the processor is cooked when the fan has been replaced, but who had already paid for another motherboard I would like someone to confirm what it means when the caps lock flashes constantly and if there is another way to fix it.

    Thank you very much in advance for any help

    Solved this problem where everyone sees the same behavior.

    CPU replaced and he started to ask right now, it seems that my predecessor Cook the processor when they changed it is fan.

  • sleekbook envy 6: laptop won't start, caps lock flashing 3 times

    I want to 6 sleekbook and all of a sudden that it does not start and the caps lock flashes three times I already saw the code flashing and tried to rest the memory but it still doesn't work, I ran in problems with the laptop before the blue screen, but it was fixed its own I think

    Dear customer,

    Welcome and thanks for posting your question on the Forum of Support HP

    It seems that your laptop has a blank screen and a blinking/flashing CAPSLOCK all the time

    If the Capslock LED flashes 3 times this means "Non-functional memory error", in order to solve the problem, replace the card memory

    Note: If you are comfortable open Notepad, you can check how much you have memory module. If you have 2 sticks of memory, you can test one at a time on the two slots individually to check if the fault is with the module module slot or memory memory your laptop [repeat the same steps to test another memory module]

    If you find the above steps difficult and that it is a hardware problem and I recommend you contact HP Support by phone for further assistance immediately to get your diagnostic Notebook and repaired by an authorized HP Certified Engineer

    You can also check your warranty here to check the status of the guarantee

  • Compaq Presario CQ62-412NR does not start. Caps lock flashes.

    The LED caps lock flashes repidadly with long breaks between each blink, the wireless light and constant and the adapter LED is steady. I read blink codes and determined, he was the processor, but the problem persists after him substituting a known good. I finished the resets power to clear the bios before and after the change of the CPU. I also tried to replace the RAM. Anyone here have a clue whats going on?

    This looks like a problem with the motherboard if you already replaced the CPU and RAM.

    It would be probably cheaper to replace the unit at this time only so, fix it or replace the motherboard.
