Continously flashing caps and num lock dv7

I've got a vista dv7-2120sa that I recently bought off ebay as spares repairs to use the keyboard, fan and battery on my long term laptop which is a windows 7 dv7-2230sa. I'm assuming the parts are all compatible but the ebay laptop is in very nice condition so would like to try and get it working. Thing is it only gets as far as a blank screen, the fan works, the disc drive works ie I can hear it moving, lights are on but the caps lock and num lock blink continuously at intervals of approx 3-4 seconds - any ideas?

I should think you might find the Product key on the lable on the bottom) on a notebook of this vintage.
The product key is a 25 character-number code and can be used to install the original Operating System. If you cannot find, use, or decipher the product key, you can buy a copy of Windows 7 for the computer and then install the HP software from the system's webpage.

Depending on when the notebook was manufactured (mid 2009 and more recent), you might be able to update the diagnostics to use the UEFI set. The main advantage of using this method is that of the GUI (graphics interface). You can live without it. Assuming you can use it, you can install the UEFI onto a USB stick and use that to run the modules.

Caps and Num lock blinking indefinitely

Hey everyone.
My brother just encountered the infamous startup error on his dv7-2045eo with blinking Caps and Num lock, but they are not blinking 1, 2, 3, 4, 5 or 6 times. They just continue to blink. What exactly does that mean? Other than that, it's just the regular startup error thing with black screen. We've tested the power supply, and it's just fine, so it shouldn't be a power issue.
The hard drives are also okay.
Any ideas?

Blinking caps and num lock lights

Opened up the lid on sleeping laptop and had nothing but a blank screen and blinking caps and num lock lights. I finally got vista restarted after turning it off and on a couple of times. Everything seems to be working, however the caps and num lock lights are still blinking every 2 seconds. Any thoughts on what is causing this?

Hello,
The blinking caps and numlock are a diagnostic feature of the Dv7 Notebook ( and others ). Depending on the combination it can be a number of different symptoms. They can be as minor as the battery having an insuficient charge or as serious as a CPU failure. I would recommend updating the ROM BIOS on your unit to ensure you have the latest fixes.- Make sure you have the latest one for your model - Here is a link to a document on the Blink Codes.

My hp pavilion dv4 screen wont turn on but the cap, and num lock blink

My Hp pavilion dv4- 2145dx and my laptop screens stays black but the key board stays on like the caps lock and the number lock, the mouse, volume, and the wifi light they all turn on and so do the fans but the caps and num lock blink every second at this point i dotn know what to do can anyone help

Hi,
First, try a Hard Reset as follows.
Shut down the notebook, unplug the AC Adapter and then remove the battery. Hold down the Power button for a full minute. Re-insert the battery, plug in the AC Adapter and see if the notebook will start.
If it still doesn't start, is there a sequence to the 'blinks' that you can match to the table below?

CAPS and num lock?

hi all,
when i need to use caps and num lock(both on at same time) to write an essay, sometimes the computer freeses. Why does it do this?

A freezing computer isn't a good thing - is it always happening with a specific application? And if so which one? You can try launching Disc Utility and repairing permissions if you haven't done so - also, the app. called Onyx is great for running your regular maintenance scripts, and it's free as well.
Sometimes a restart may clear things up too. Try some of these and see if there is a difference.

HP Laptop. Blank screen and caps and num lock lights flashing.

Hi,
I hope you can help me.
My laptop is the HP Pavilion DV6-1216sa, bought new in September 2009. When I turn it on, I get a blank screen, the fan is working and the wifi, volume and mute lights light up. The caps lock and num lock lights flash together, once everyone 3 or 4 seconds. Normally when this happens (it has happened throughout the life of the laptop), I turn it off and turn it back on, and it works again. However this time, the problem persists. I've tried most combinations to get the bios screen up and I've tried getting it to another screen via hdmi and VGA, but no signal received. I have tried everything recommended by the HP support website. I have checked the battery, ram, and hard drive.
Best regards,
Jay

The best cheapest fix is if you can remove the motherboard your self and send it to a refabricator who will check all the chips on the motherboard and reball the bad ones. Cost is about $60-120, closer to the bottom if you can ship them just the board but if necessary they will take the whole laptop and remove the board for you.

CPU not functional - 1 blink of caps and num lock

I have HP Pavilion dv4 Notebook
It started giving me blank screen with caps lock and num lock blinking, and I went to the HP support and found out that it has something to do with "CPU not functional" thing. I have to say this diagnosis is bogus and on HP site it says I have to contact HP support for this, and when I go to contact HP support they said my warranty has ended so I cannot even send them an email about it except come to this forum again post my grievance. It seems this error is happening to many customers, and if I remember correctly CPU is not something that will go wrong suddenly, maybe the motherboard or battery, but all hardware parts not the CPU. It seems there is a known issue with DV series of notebooks where this blinking is happening. To your surprise I'm now using the same laptop to post this while the lights are still blinking. The best place HP support directed me was either to pay for service or to contact recycling, REALLY? Is this really the award-winning support HP has. I am dismayed with the intricacy the site has in getting your problems heard by HP and get a resolution. So here I am asking for the community forum if they have fixed their laptops after getting the famous "CPU not functional" error.
And now before I submit this, the cpu fan has started to make very scary noises, just like a small motor bike, somebody please help me.

My HP Pavillion dv4 has a black screen and blinking Caps and Num lock

BEFORE anyone says to take out everything and press the start button for however many seconds, i've tried that. I've also tryed counting blinks, but there seems to be no pause in blinks, thus continuous blinking.
SO, recently i have updated my laptop, i let it shut off but i did not choose for it to restart. Today when i tried to turn it on, the screen was black, did not turn on and the caps lock and the num lock have been blinking continuosly, without pattern. The touch screen volume and such is also on and after a few seconds the fan turns on. There is no loud beep, just the regular startup soft beep. So, i would like to know, if anyone knows what i can do, before i have to go and pay to fix this thing.

i have took it to the apple store, i am out of warranty and they said it is a hardware problem, god knows whats causing the black screen it is fine when on as i got it fixed at a local phone shop but when the phone dies then there is no bringing it back to life.

Caps and Num locks on - typing lowercase

After today's auto-update of my MBP 2.2 (macbook mackbook pro software update 1.1) the capslock and numlock lights are on by default but typing is in lowercase... quite annoying as to use the numberic pad the num lock light has to be off. Another flaw in the MBP.. I bought mine 2 months ago, I am experiencing 5 dark (dust like) spots 'behind' the screen, always there on a light background, the problem with the baklight switching off after 30 seconds no matter what settings (a known problem) and now the caps/numlock problem..
As a long time Apple user (starting with a Lisa) and having developed several mac based applications, I am currently believing that Apple has serious problems.. the lack of QA in both hard- and software makes Apple stand on the same level as nameless clone makers from Taiwan (only with a significant but unjustified higher pricelevel)
The support here in Belgium is terrible, to fix my display errors I would have to miss my mbp > 4 weeks which is unacceptable.
Dissappointed..
Jan Ronken

I am currently having the same problem. I did a Software Update today and when my computer started up, it had the "Num Lock" and "Caps Lock" lit up by default.
If I _shut OFF_ the "Num Lock," it types only numbers.
If I _shut OFF_ the "Caps Lock," it types in CAPS.
If I _turn on_ the "Num Lock," it will type like a normal keyboard with the correct key assignments.
If I _turn on_ the "Caps Lock," it will type in lowercase letters.
It as if everything is in reverse when they are turned on and lit up on the keyboard. Anyone have a solutions for a fix?

Post Leopard install, caps and num lock have opposite effect

Not sure what I did as I was running Leopard just fine on my MB Pro rebooted and found my Num Lock light was on. Turning it off resulted in the keyboard behaving as if it was on. Also when caps lock is on I get lower case, i.e., normal behaviour when Caps lock is off. When caps lock is off I get ALL UPPER CASE AND CANT GET LOWER CASE.
What did I do? I've checked keyboard settings, but can't seem to find anything that I might have inadvertently done.
Mark

Actually this is a new feature of Leopard.
The developers have been wanting to rewrite some of the conventions that we use when operating computers, such as the much boasted about (and fraudulently claimed that they invented) multi-touch. and so they patented the reversal of these keys for us all to think, wow this is amazing and new! Apple are so cool and hip, nothing like those copycat MS people!!!
But seriously. Try fixing disk permissions (in disk utility) and also reset the System Management Controller by removing all power and cables into the computer for at least 15 seconds.
http://docs.info.apple.com/article.html?artnum=303446
Good luck, and if all else fails try doing a clean install. I assume that you only did an upgrade so that u wouldn't have to reload all the data from the computer!?!

DV6 Flashing 2 times Num Lock and Cap Lock Keys on Startup

Hi all.
My computer (HP Pavillion DV6-2062eo) flashes 2 times on CAPS and NUM LOCK when turned on.
The tables on former post-messages says it's BIOS Corruption.
How to solve this ??
Regards,
Frank

Hi Chris,
See if you can match the pattern of the 'blinks' to those shown on the table below - this may atleast give you a better idea of what the problem is.

Hard reboot with binking caps lock and num lock lights DELL XPS M1530

After returning from work I saw my DELL XPS M1530 had hung and there was blinking CAPS and NUM lock indicators, I had to hard reboot.
This has happened with me some times.
How can I investigate? Is there some log which i can see after hard reboot?
I am on kdemod 4.1.3 with nvidia stable driver
Last edited by venky80 (2008-11-18 00:44:15)

I used to have that problem on my laptop also. It seems to plague a good number of XPS 1530 owners. From what I can tell the problem seems to be either graphics card drivers or wireless card drivers. Do you happen to have the intel 4965agn card? If not, what hardware do you use for wireless and graphics?

Satellite C55-A and Ubuntu - Caps Lock and Num Lock key leds always off

I use Ubuntu Desktop 14.04 and Mate Desktop and LightDM. My Toshiba Laptop is Satellite C55-A-1JH (PSCG6E) model.
Cap Lock and Num Lock is working , but their leds always is off.
I don't find any Linux driver in Toshiba support web site.How I solve this problem?

Hi. Are you sure this is a Linux-issue? Please try this: reboot the unit and press F12 several times when the Toshiba logo is shown. When the boot menu is shown try Caps and Num lock again.
Same issue or not?
