  Hello

  First of all, regarding the manual of maintenance on the link below--remove and reposition your bars of memory.

  If the above makes no difference try the following.

  Again, regards to the manual on the link below, delete one of your modules from memory and then see if the computer will start.  If it doesn't, try the same module, but in another location.  If it is still won't start, try the other memory module in both slots, to see if any combination will allow the laptop to boot up normally.

  The procedure for withdrawal of these modules is detailed from Page 63 of your & Maintenance Guide.

  Kind regards

• HP Pavilion G6: Black screen, Cap lock blinks and turned on wifi in orange

  Bought this non-functional computer for $40.  The screen is black, the caps lock flashes and the wifi light is lit in orange.  At the time, we could hear all the computer starts, the fan would go, the drive initialize... so I watched a few videos on the problems of black screen on youtube, he got up and running.

  However, it is a tease, she worked for less than a month.  I does not solve the problem which has been heat.  I buy quadfans for going below but they turned off during the night and should not have.  I have the computer to check the updates at 03:00, so the computer would then come and fans wouldn't.

  Well, the black screen problem is backkkk.  The fan don't dΘmarre, try the hard drive.  This time nothing is set.  Ive pulled the motherboard to replace the fan.  I replaced and updated the hard drive and memory... still nothing.   It also has a new battery and power cord.  Any suggestions as to what may be the problem?

• 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?

• 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.

• 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.

• Caps lock flashing, will not start

  Hello!!

  I have a hp pavilion dv6. last night it worked great, sa I closed my laptop, it went to sleep mode with the adapter plugged but without battery. today when I tried to boot up my laptop, I opened and it started only now I get a black screen with caps lock flashing light, I read on the site on an error that the plugs lock this blink, how many times it flashes before, but, my flashes more than 50 times, according to me, strange worm. What can I do about it?

  Thank you!!

  Hi Steve,

  Unfortunately, there are many possible causes for this problem, I mentioned the video chip as possible example given the symptoms you describe - you need get the machine examined to ensure.  Failure of a component is often extremely fast, insofar as it works one minute then is not the other.

  Kind regards

  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

• 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.

• Pavilion G6 Caps lock flashes constantly but the laptop work.

  Hello!

  I've owned my HP Pavilion g6-2292sa Notebook PC (running Windows 8) for about 4 months now and tonight, so I was watching just the net that I noticed that my Caps Lock led flashing continuously, a flash every second. My laptop works fine, and I rebooted to try to stop the flashing, but with no luck. I checked Flash and positions that average hot flashes but mine does not fit in all of this. It is starting, it is not beep just the caps lock flashes constantly. I checked my other lights and see no other spazzing out like that. I'm rather worried because I had to have a new motherboard and HARD drive in a month of purchase. I googled not materialized. Can someone help me please?

  Definitley weird!

  Can you check the UEFI environment in F2? Let's see if it happens there inside and outside to win 8.

  If it happens again, we can try a hard reset - remove the battery and AC and hold the market for 30 seconds, then plug back in. We can also try a BIOS flash - checks whether there is a newer version or re flash.

  If the problem does not occur in BIOS - then you can try a Virus scan / update or restore possible system

• Black screen on startup, caps lock flashing - Compaq Presario CQ57 311SO

  I got this computer from a friend who owns a son.

  We do not know how or when it appeared first, but it's in this State for a few months now.

  It is a Compaq Presario CQ57-311SO and its a little more than 1 year, so store warranty has expired.

  What happens is that when you press the button power has nothing to display on the screen and you do not hear the sounds of typical start-up, the beep and the hard disk rotates upward.

  Instead of this, the Caps Lock key led flashes in the following model, 2 flashes pause 2 flashes.

  The computer is totally immune to any key, usb and cd entries.

  I tried the hard reset and memory sharing in different locations.

  But it seems that the bios itself is corrupt and failed.

  So my question is, can I Flash the bios somehow and make it work again?

  I tried a tutorial on how to do memory flash in FAT - 16 but no noticeable effect.

  Although the guide could be wrong or I could have done something wrong so I would really like to try again if I could get help with instructions from you nice people

  Thanks in advance.

  I solved the problem in dismembering the computer laptop everything and put back the battery CMOS.

  Thank you.
