No display while caps lock LED blinks

Hi
Please could someone help me.
For about 2 weeks now my laptop has refused to display anything. When I turn it on, nothing displays on the screen but the caps lock LED blinks once every 2 seconds. Also the wireless button displays orange light but nothing on the screen.
It managed to display once in this 2 weeks and the error message I was able to see before it came on read something like:
HP Battery Alert
The system has detected the storage capacity of .....(did not see all the message on this line)
very low. For optimal performance, this battery .... (did not see all the message on this line also)
Primary(internal) Battery (601)
ENTER - Continue Startup

Caps-lock and scoll-lock LEDs blinking

Ok so a friend gave me 2 dv7-1245dx laptops. When I turn them on both screens do nothing,and the caps and scroll lock LEDs blink every 3 sec apart. On one of them the dvd drive also acts like it is trying to read a disc. External monitor didn't owkr,nor did changing ram to a set that know works,and swapped CMOS batterys between the 2 didn't help either. Also did a hard reset which also didn't help. Any suggestions?

It sounds like they may be experiencing a processor failure if it blinks only once with a 3-4 second pause between each blink.
Review this document as it has the decoding table for the blink codes.
One blink indicates that the processor has failed. While it is is unlikely to happen on two notebooks simultaneously, it's not impossible.
The steps listed in the document is to reseat the processor or to have the unit serviced.
Normally, HP has a guide for most of the notebooks on how to reseat/replace the processor. However, this particular system does not list the maintenance and service guide here.

Bricked my touchsmart -tx2 1025dx. Cap/Num lock LEDs blinking once.

Bricked my touchsmart-tx2 1025dx. Cap/Num Lock LEDs blinking once, so I replaced the processor but the LEDs are still giving me a single blink (processor issue). Any advice?

Hey NikosK,
The one-blink code is indicating an issue related to CPU and/or system board (bent pins, etc.). It's possible that the system board needs to be replaced.
Here's a table of all of the LED codes:

Do you know what caused this issue in the first place, before replacing the processor?

Pavilion DV4-1070ee got stuck on a blank screen and numlock and caps lock LED are blinking..

My pavilion dv4-1070 got stuck on a blank screen and numlock and caps lock LED are blinking... it happens when i update the BIOS.. please help... thanks

Hello,
I see that you're having an issue with the notebook giving you a black screen. I also noticed you said only the NumLock and Caps lock is blinking.
Now, the BIOS update could have because this but we won't know until you let me know how many times the LED blinks.
Here is a chart which will tell us what's causing the issue.
Please let me know the outcome.

Occasionally my caps lock key blinks some time later my keyboard locks up what is causing the blinking and is it related to my keyboard locking.
This blinking occurs when no keyboarding is going on.
Back-up is not running.
I am on-line.

Anthony:
The normal practice is to use the Shift key when typing a single Capital letter, as in a name or the beginning of a sentence, and the Caps Lock key to type all caps. The easiest thing would be for you to retrain your little finger to use the Shift instead of Caps Lock. I know of no way to display an icon at the bottom of the monitor to display that the caps lock key is engaged.

Laptop freezes at HP logon screen, edit to post Caps lock key blinks 5 times

Hi,
This is an edit to my original post,
I have also noticed the caps lock key blinks 5 times in fairly
quick succession then there is about a second delay then
it keeps repeating the same pattern,also the number
lock key is also on
Don`t no if this has any importance?
Thanks again
I hope I`m posting in the right place, please forgive me if I`m not
I have a HP Probook 4535s (now out of warranty)
When I turn it on it freezes at the Hp start up screen
It does`nt matter which "F" key I press after a few
seconds it starts to beep (not in the identifying a
problem way) This includes the "Esc" key
Whatever key I have pressed it goes from just
text to having a white box around the text
but does nothing
I have reseated the RAM and them replaced
it I have also replaced the HDD, although it
is maller than the original all with the
same results, so am at a loss.
Any help and guidence would be most appreciated
Oh sorry I have also removed the battery and held
down the power button to purge it
Thank you in advance for reading my post
Best regards
Neil
ps I have not got the recovery disks (lost when we moved)

Sorry to hear that. Please refer to the Blank Screen LED Error Codes document from HP Support. It sounds like a "General system board failure." The explanation says to contact HP for assistance. The motherboard might need to be replaced, and you will probably require the assistance of a technician to fix the problem.

Caps lock LED not working consistantly --SOLVED

Not so much a question as an answer. I searched earlier for an answer to why my caps lock LED would not light up. Still no clue, but I found a quick fix. Press and hold power button for wireless keyboard until it disconnects from the computer. Wait 20 seconds and turn back on. This should solve it completely.

Hey,
Sorry to hear about the keyboard problem.
In a post a while back had this to say. He makes a suggestion that the keyboard might need to be replaced, then the person with the question tried something else. You might take a look and see if there's something there that will help.
Thanks for coming to the forum.
Hope I helped,

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.

Caps Lock LED incorrect when changing modifier keys

Hello,
I remapped Caps Lock and Ctrl keys via keyboard settings (they're now flipped). Unfortunately the Caps Lock LED is still being activated by the "old" Caps Lock key (which is now the Ctrl key). This means that whenever I hit Ctrl (using the Caps Lock key) the Caps Lock LED changes its status.
This is rather annoying as it ends up being in random state and tells me nothing about the actual Caps Lock status. Is there a way to fix this?
Thanks!

Hello:
I suggest you call Applecare with a warranty issue. The KB has a one year Apple warranty. I would not waste any more time trying additional things. You have already tried everything I would suggest.

There is no known malware capable of infecting an iPhone that hasn't been jailbroken (ie, hacked to allow apps from outside the App Store).
If you have jailbroken the phone, and jailbroke the last phone as well, that is certainly the cause of the problem. Restore the phone to factory condition, without restoring any backups, to remove the jailbreak, and any potential malware you might have become infected with.
If you have not jailbroken the phone, it's not malware, it's probably a hardware issue. If you have had the same problem on two different phones that were not jailbroken, you need to evaluate what environmental factors might be at play causing damage to your phones. It could be anything from a bad USB port/charger that you're connecting it to, an overly-humid environment, a tendency to drop phones or any number of other things.

Caps Lock LED don't turn off

Well, I got my notebook from repair today, and looks fine, but... The Caps Lock LED won't turn off, no matter what I do. I'm still downloading ALL the drivers, so, if I need a special driver for turning on and off the leds os Caps Lock, tell me. And the LED of the Wireless key is working perfectly, white when turned on and red when turned off.
And I getting some issues with the TouchPad, because it don't turn off too! I'm hoping when I finish downloading all the drivers some problems will go away, but, if you can, may you help me with that issues ?
My noteboo is a Pavilion DV7 6143-CL with Windows 7 Ultimate.

Hp dv4-2112tu no boot no display , ram and hard disk are ok and checked, shows caps num led blinking

Hello Sir/Madam,
I have HP DV4-2112TU
My laptop doesn’t boot completely and shows blank black display. CPU fan running normally and hard disk rotating normally.
Battery charging is ok and charging-power led glows normally. Caps lock and Num lock led flashes 3 times and then wait for one second and then flash again and so on. Laptop is stucked in booting process.
I have checked both of my RAMs and Hard Disk in Another Laptop. All are working fine and shows no issues.
I have also checked my laptop installing new RAM in both ports (simultaneously) and a new Hard Disk but Laptop shows same problem - no display no boot.
I showed my laptop at an authorised HP Service Centre... they told me that the problem is related to my Hard Disk....But this is wrong Because a faulty hard disk is never cause no display and no boot and even no BIOS POST message. They told me wrong cause of fault because I have checked Hard Disk and it is OK.
Can anyone tell me what are the issues related to my Laptop..... …..
Thanks in advance.
This question was solved.

Hi,
The 3 blink pattern does correspond to issues with the memory modules, see the document below:
Computer Does Not Start and Emits an LED or Beep Code
Since it sounds like you've done everything possible to eliminate the memory modules themselves as the source of the problem. Based on your description, I'd agree that the problem is probably not the Hard Drive. Which unfortunately leaves us with a problem with the Motherboard as the only component that might be implicated and that hasn't been changed out yet. It could be as simple as a bad connector, or something less easy to detect in the logic on the board, but either way, it seems like it would need to go back to a service center for repair.

Caps Lock/Num Lock LED blinks 5 times on bootup - HP ProBook 6450b

Hi all members/pros, I was tasked to resolve a bootup issue on a HP ProBook 6450b and did managed to get it up and running again without much effort. The notebook Caps Lock/Num Lock LED flashes/blinks 5 times and then pauses and blinks again 5 times. Seeked assistance on online HP support(link below) and it stated that it was a System board failure. http://support.hp.com/us-en/document/c01732674 So then I opted to swap the hard disk tand LCD monitor hardware with with another HP ProBook 6450b which is functional but display damaged as the user was a senior manager at where I worked - Boroko Motors, Papua New Guinea - and prolong downtime was not an option. Just as I was about to get under the hood, the buggered notebook deciided to spring back to live loading onto the Windows login screen. I noiced also that I was in our server room(with much cooler temperature) that may have aided the componenets on the main borad to function so I presumed the cooling system was at fault. I then got under the hood and confirmed that the fan/vents were clogged up with dust/debris which might have collected over time. Did the cleaning and after that it hasnt failed so far... Thanks all! Get the HP ProBook 6450b service manual here: http://h10032.www1.hp.com/ctg/Manual/c02760808.pdf

I, recently, bought a 6735b hp laptop for $100. It does the same thing as your describe. I think the motherboard overheated. So, I ordered a new motherboard from getcomputerparts.com out of China to see if it will solve the no boot problem. I'm hoping this will solve the problem. I noticed that when I first got the laptop, second hand, that the fan wasn't blowing out, and later found a lot of dust that simply blowing it out solved the air circulation problem. I think that the heat destroyed some connections to the video or hard disk drive controller chip which made my hdd light blink on and off every second or so, and also made my Optical Drive seem to blink its LED on and off, and a slight scratching sound every second, as well.
I also, saw on Youtube.com, a video about the nvidia video chip getting connection heat damage at the solder joints, and there was a way of putting a penny with heat sink paste after 'burning' it for a couple of hours with a hot spotlight lamp with aluminum foil around the rest of the board to protect the rest of the board other than the video chip. But, this was on another hp product that failed after 1 year, no screen no POST.
I am hoping a 'new' system board will do the trick though, and I am spending about $153 for the part delivered, and $75 to put it in at a local computer shop.

HP Pavilion DV3 ( Scroll & Caps Lock LED's blinking four times + Blank Screen )

Hi,
I have an HP Pavilion DV3-2157cl
When I press the power button, the screen remains blank. Also, the scroll & the Caps Lock buttons keep blinking four times.
Sometimes, the laptop works like nothing's wrong but Most of the time, it remains blank with the blinking lights!
Can anyone help me?

i had a problem with my dv3 (blank screen keeps flashing) and used this method to reflow the graphics card/chip (see link below). only try this method if you are at your wits end... and you are skilled with taking apart/putting together electronics. it will take you a minimum of 1 hour (but most likely, about 2). you will need a heat gun (about $10 - $20).
http://www.youtube.com/watch?v=SziIr34Md0g
to prevent it from continually over heating, you can try the penny mod (google it). that's what i did. you basically take a penny and sand off both sides until it is the right thickness and solder it onto the heatsink. you'll need to remove the sticky blue foam that HP used instead.
i also noticed that a laptop cooler placed under your laptop works well for keeping it cool. it can be fixed again and again using the method above but it is time consuming. to prevent getting a cold connection which leads to this problem, don't move the laptop. yes, it sucks that you can't move it but that's the only option you have.

Hi, I have a problem with my Pavillion dv4-1222nr. It was fine last night and this morning when I turned it on the Scroll/Num Lock and Caps Lock lights started blinking.

I can hear the fan from the processor and the dvdr engaging oh, that light is blinking too. I pulled out the battery to see if it would reset but it didn't work. Can anyone please help

Hi, I have a HP Pavillon Dv4 1225 dx. Since a week when I turn it on I hear a noise that seems that it is going to start but it doesn´t. The scroll, num block and caps looks bottom are blinking all time and the screen remains as if it were off, even if I wait for an a half an hour. I tried changing the memories, connecting another monitor, checking the battery but it doesn´t work. I would be great if you could give me an advice about what can I do to solve the problem. Kind regards
