Pavilion dv6-7010us black screen, caps lock blinking indefinitely and orange wifi light

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?

What did the normal maintenance include-any disassembly? I assume the laptop is still under warranty?

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)

Hp g62 Black screen caps lock on and wifi button on

Hello,
My friend is having a problem with his laptop hp g62 which is 1 1/2 years old. This happened out of no where and have no idea why. Here is what happens: We power it up, fans turns on, caps lock stays on and Screen stays blank. Again we have no clue why this is happening. Any help will be apreciated.

Hi,
It's always worth trying a Hard Reset as follows.
Shut down the notebook, unplug the AC Adapter and then remove the battery. Hold down the Power button for 30 seconds. Re-insert the battery, plug in the AC Adapter and see if the notebook will start.

Pavilion dv6-3040sa, black screen, flashing caps lock

Hey all, In need of some help for a friend, her laptop has had this issue for a while now and only just come to me for help. Her HP Pavilion DV6-3040SA has an odd issue with it, if you power it up the display doesn't come on and the caps lock just flashes, it will continue to flash until the laptop is turned off. On the help section a flashing caps lock does not refer to any particular error. I've reseated RAM, tried hard resetting, reseated the CPU and it managed to power up, then after it was turned off, it wouldn't power up again and had the same issue, after playing with it some more it powered up and worked for 2 days, when it promptly stopped working again. Any reason for this issue?

Processor failures can be have inconsistently. I have seen processor failures start with 1-2 second hangs in the OS to working one day and not at all the next.

The options for a blink code of 1 is to reseat the CPU as you have already done or to replace the processor. Since the issue returns after reseating the CPU, it looks like the CPU needs to be replaced. Sorry.

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.

Hp G62-a70SV Black Screen, Caps lock not blinking

Hello,
My hp G62-a70SV gives me a black screen when I push the power button.
Caps lock isn't blinking at all, wifi led is on.
Nothing is ever displayed on screen. I hear eventually the windows starting, but nothing more.
I connect external monitor, but there is no signal.
Is it problem of the display adapter on the system board?

Hi,
It's always worth trying a Hard Reset as follows.
Shut down the notebook, unplug the AC Adapter and then remove the battery. Hold down the Power button for 30 seconds. Re-insert the battery, plug in the AC Adapter and see if the notebook will start.

Black screen caps lock key blinks

Laptop screen is blank and the caps lock key blinks 3 times over and over..Tried doing what was suggested, taking out and reinstalling the memory card..also blew out the dust and didn't fix the problem ..I think it's Windows 7 installed.

Hi there @Philvasquez
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 am sorry to here that you are getting this particular error code and that your initial troubleshooting has not helped.
I assume that you were looking through this page, and followed it.
Computer does not start and the LEDs blink or the computer beeps
LEDs blink 3 times
Memory
Module error not functional
If you have followed the process within that page, related to a memory problem, and it is still doing the same thing, then you are looking at two possibilities. One or more of the memory modules in your notebook is defective, or the main board has a faulty connection.
You can try testing the memory individually or by swapping them (if there are two) into the different memory sockets. Doing this you can isolate if one memory chip or the other is defective, or if it is a socket problem.
Once you know which problem it is , you will likely need to get replacement memory, or a replacement board, or in a worst case both.
See the following, for more details on the compatible parts and type of memory that are supported.

Hp pavilion dv6 laptop black screen

Hi all please is any one help me I have my hp pavilion dv6 laptop.
The laptop is working,have the necessary sounds after i
turn it on,but the problem is that the screen stays always black
..I connect the laptop to external monitor and it shows that everything is working properly. But It not working on laptop screen what should I do heplllllll

Hi
I'll try helping you with this,
You'll have to give it for repair - display assembly replacement. The display panel might be at fault here as your system works good when connected to external monitor.
But before that,
Do a hard reset first --
Turn off the computer by pressing SHIFT KEY while you click SHUT DOWN.
Remove the computer from any port replicator or docking station.
Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers.
Unplug the AC adapter from the computer, shut down system.
Remove the battery from the battery compartment.
Press and hold down the Power button for about 15 seconds to drain any residual electrical charge from the capacitors that protect the memory.
Insert the battery and plug the AC adapter back into the notebook computer, but do not connect any of the peripheral devices.
Press the Power button to turn on the computer.
Next:
To confirm, connect it to other monitor & do a full extensive hard drive & memory test from BIOS, tap quickly F2 or F10 soon after powering on the system.
If all tests are passed, contact HP service center.

Pavilion dv6-1230us Black Screen after installing Windows 7...Please Help

Hi,
I recently installed Windows 7 and everything was working fine until my computer went into hibernation. Before this, I installed all the drivers and software from the HP website for my computer for Windows 32 bit setup. After my computer went into hibernation, my computer will not start up in normal mode; rather, it starts in safe mode only. When its starts in normal mode, the screen just turns black and nothing happens. The login screen comes up perfectly fine but after I login at startup, the screen just turns black. Please help, I don't know what else to do whether it is a driver or software issue from the software from the HP site.
Thanks,
Daniel

Envy Dv6-7210us Windows 8 caps lock blinking continuously

Hi,
I noticed that there was a password set on my BIOS and I read in the forums that I could reset that by taking out the CMOS battery. Well I did such and while I was doing that I decided to clean my keyboard and fan unit, so I undid the screws for the keyboard and took the keyboard off. Now, after putting everything back together, my laptop will not turn on to the BIOS and thr caps lock light is flashing continuously and thr wi-fi amber light is on. I know the continuously single flash usually means there is a problem with the CPU, but I am wondering how this could have happened. I have done everything from the forums such as reseating the memory modules, trying to restore the BIOS, letting it sit overnight while running, power resetting, and taking out the CMOS battery again. Is there any other steps that I could be missing?

Hi,
This is the Maintenance and Service Guide for your Notebook: http://h10032.www1.hp.com/ctg/Manual/c03591281.pdf
Can you please go through the replacement procedures of the components that you already replaced and confirm whether you had done everything accordingly? We will have to make sure that we are not missing on anything that is not letting the Notebook boot properly now. Please take utmost attention when you check the procedure for the procesor. If we miss on a small thing, it could be a problem.

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.
