HP Pavilion DV6 blank screen caps lock flashing continuously

My laptop was working fine last night, this morning the screen stays blank, caps lock flashes once every 3 seconds or so continuously, the wireless light is solid amber, no other lights are on. I've tried a hard reset to no avail.
When I power it on it sounds like the fan spins up and it tries to boot, then 2 seconds later it is quiet and nothing happens, if I close the lid without powering off the outside light on the top of the case stays on so it is not shutting down or in sleep mode when the case is closed.
I've looked at a bunch of troubleshooting and none of the info seems to match this, any help would be appreciated.
Thanks

a single CAPS flash is a CPU failure, you can try following the below steps but it will most likely need to go in for repair
power drain;-
-remove battery and power cable
-hold power button for 20 seconds
BIOS recovery;-
-hold windows+B
-turn computer on keeping those keys held down
if the light is still flashing at this point you'll need to contact HP, if it is in warranty then the repair should be free, if not there will be a cost

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)

****PLEASE HELP ME SOMEONE**** PLEASE - Re: ON SCREEN CAPS LOCK INDICATOR

can someone please help me before i pull all of my hair out.
i have windows vista - 64 bit - the HP IQ500 touchsmart with a wireless keyboard.
in the systray the num caps and scroll lock appears as little blue boxes (when on).
everynow and again they simply disapper.
i researced how to activate them again but cant remember how to do it.
there is a way without having to mess with the registry and without downloading any program
i just cant remember how. i know wherever it is...you ultimately get 3 boxes that you can check in order to turn the options back on.
i am not talking about toggling, or sound, or mscofig and then boot.
does anyone know the steps to turn the caps scroll and num lock indicator in teh sys tray back on
oh, and right clicking on the toolbar and going to the notificiation area is not what i am referring to either.
I checked in the control panel programs and the hp on screen caps lock indicator etc program is there.
I reinstalled it nonetheless and confirmed it is installed properly
When I right click on the notification area I do to properties/notification area/customize
There are two lists there
1. Current Items and
2. Past Items
For some reason I see caps lock - scroll lock and num lock under the past items
There you are also able to change the status of the items to either Hide wne active, hide or show
All three (caps/num/scroll) are SHOW
I click apply OK then apply
I restart the computer and nothing. The on screen caps lock indicator is still not in the notification area/systray area
I repeat teh steps to ensure that the three have the SHOW option chosen and they are.
So....
Program is installed
Items are check for SHOW
Restart was done
Ohhh and also...I went to MSCONFIG and made sure that the HP Keyboard Program was selected/check mark as one of the start up programs.
There in a run command to activiate the 3rd party program (hp onscreen indicator program)
When you enter the run command that I cant remember...you then get this option where there are three check boxes...one next to num lock - one next to caps lock and one for scroll lock.
Once you check/select the boxes/options you want...presto they appear in the sys tray/notification area.
I just cant remember the run command it to save my life.
Please....put my mind to ease...cause I am losing it!
I just cant seem to "walk away"...must be my OCD :-(
Thanks

I am having trouble with my MacBook Pro. I get a blank screen with a flashing document file with a question mark in it, yes I have tried to install Mac OS X with the original disk but I get no choices of where I wish to install Mac OS X. Please help ;(

I am having some trouble with my computer, what happened was: I was playing on a game, I played with a magnet, it started to go slower and slower, I pressed F9 then it went slower and then it went to a blank screen with a flashing document with a question mark on it. I tried the original OS X installation disk but when it came to choosing the area of which I save it, it showed no areas.

Startup your Mac while holding down the Option key. That should prompt the Startup Manager window where you can select the startup disk then click Restart.
If the startup disk is not available from that window, you may be able to repair the disk.

CQ57 caps lock flashes

CQ57 366SA It started with a failed bios update. Caps lock flashes twice. Tried and failed to recover following steps found on this site. Now caps lock only falshes once. Still no boot. Help needed please

Hi,
If you have an option to roll back to previous BIOS version, then you can try it. After that if the issue still persists with 1 flash on the caps locks, then its an issue with CPU which you have to get it checked.

Sir,
Today morning I turned on laptop but laptop won't boot and wireless button glowing continuously and also caps lock blinking continuously as 1 blink per 4 sec.

HP ProBook 6540b won't boot and caps lock "blinking" continuously.

Hi,
I'm trying to help a friend with his laptop a Probook 6540b.
It won't boot and caps lock "blinking" continuously.
When I got it caps lock and num lock was "blinking" tre times... indicated memory problems, reseated the memory modules
and the the "tre time blinking" disappeared, but caps lock now blinking continuously and the only way to shot down the computer
is to disconnect the power.
Anyone with some ideas???

A neighbor had the same problem and asked for my assistance. I created a rescue disk using my HP desktop running Windows 7 64-bit. Even though her HP laptop was running Windows 7 32-bit, the disk allowed me to boot into windows on her computer. I then went to the HP web site and downloaded the latest BIOS and then flashed it to the BIOS chip following the instructions that came with the download. Everything is working fine now. Hope this helps.

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.

The laptop is a HP Pavilion dv6-7010us resently installed windows 8.1 pro, 8gb ddr3 (4gbx2), 320gb hdd (not the original hdd)
i was giving a normal maintenance to the laptop to remove the dust, nothing of the other world, the machine where functioning pretty well 'till this moment, i turn on the laptop and i see the caps lock blinking at 1sec intervals and the wifi light in orange not blinking just led on when i turn on (NOT NUM LOCK LIGHT ON), and this is it, nothing more, i dont know what to do, i use the WINDOWS KEY + B to reset the BIOS and nothing, i leave the power botton hold for a minute without the battery nor the power source, and plug the cable and turn on again without the battery and nothing, also where testing changing the memory from slots i have 2 memories of 4gb and nothing, anybody can tell me any combination of keys to resolve this that i don't use yet?

DV6-7010US Caps lock flash, no POST

System was not used for several months. When we tried to use it, the system was extremely unstable and crashed several times with Windows blue screen errors, randomly didn't detect the hard drive, etc. Then it just stopped booting at all, and instead has the orange WiFi light with the caps lock LED flashing once every second (or so) indefinitely. LED error codes list says this is "CPU not functional." Since then, both the motherboard and CPU have been replaced, but the system still gives the same LED error code.
Motherboard was ordered straight from HP Parts surfer, CPU from a 3rd party company with guarantee that item is tested as fully functional. Reports from this forum and others on this system and motherboard replacements are not overly positive. I'm tired of dumping money into this laptop and it not working. Any suggestions would be greatly appreciated.

Hi,
Remove the hard drive and boot up. If you can get to the BIOS, the hard drive is faulty. It's highly unlikely that the new board and the cpu will cause exactly the same error. It means that some other component from the system must be faulty.

HP Pavilion DV6; Black Screen & Atikmpag.sys BSOD with external Monitor

Hello Guys.
I have HP Pavilion DV6 Core i7 with ATI Mobility Radeon HD 5650 Graphics Card. Two weeks ago, I started getting continous Atikmpag,sys BSODs. The operating system also started giving me warnings about the hardrive. After a few days, the BSODs got more frequent. Then one day, I was doing normal stuff on my PC and the Display Driver crashed. Instead of recovering, the PC froze. I forced restart my PC but it got worse. The display of my laptop went black. I connected the laptop to external monitor which detected the display. When I tried to load the windows, it started giving me the Atikmpag.sys BSOD on the start up. Now the operating system works fine in the Safe Mode but with nothing on the laptop's screen. The soultions I have tried so far are.
-Reinstalled the windows thrice
-Removed the drivers and installed the updated ones a bunch of times.
-Rolled back the bios to an earlier version
-Removed the hardrive and tried to load it from an operating system installed on external flash drive
-Tried loading the PC with linux on external flash drive
-Opened the laptop and cleaned it thoroughly
-Removed all the components and plugged them one by one.
-Removed the old Atikmpag.sys in system32 folder and expanded it with the latest ones.
-Installed every thing fresh from HP website
None of these tricks have given me any luck yet. The only way, I could use the operating system in normal mode, is to delete the atikmpag.sys file in safe mode and then log on back in normal mode. I also analysed the minidump file through window debugger and it says that atikmpag.sys is causing this crash with the TDR message. I did all these with an external monitor as the display of the laptop is black since that day.
Below are the detailed specs of my laptop.
OS Name: Microsoft Windows 7 (64 bit) Home Premium
Version: 6.1.7601
System Model: HP Pavilion Dv6 Notebook PC
Processor: Intel Core i7 Q 721 @ 1.60 GHz
Bios Version/Date: Hewlett- Packard F.29, 11/7/2011
Installed Physical Memory (RAM): 6GB
Graphics Card: ATI Mobility Radeon HD 5650 1 GB
I have tried almost every solution available on these forums but still have not gotten any where. I am wondering how could the display, graphics card and hard drive stop working at the same time .
I would really appreciate if someone colud help me through this problem.
Thank you
P.S. Kindly ignore my English mistakes as it is not my first language.
