Slow blinking caps lock, blank screen

Only had this laptop for a week now, powered it up this morning, hard drive appears to run, fan is on but LCD screen stays dark and the caps lock is slow blinking (no apparent pattern).
The model is: 2000-104CA
Product: LV987UA#ABC
Rev. : 3577-100
Also, I tried removing the keyboard (after the fact) and the video instructions, located here: http://h20574.www2.hp.com/results.htm?SID=5059088&MEID=FAA31BDC-56B6-472D-BA7B-4295B0216628 seem incorrect.
The instructions state to remove 1 5mm P1 screw, then press down with a probe tool in the hole indicated. All I ended up doing with pushing out the "insert" key. I can slightly lift that top side of the keyboard but there is definitely something locking down the keyboard around speaker mute/speaker + function keys.
Can anyone enlighten me about these two problems?

You will need to search Google or YouTube. Even then, you probably wont find the exact model you have. Most keyboard are lastly connected with a very fragile ribbon connector. Its usually 'locked' in with a sliding plastic piece right where the ribbon meets the motherboard.
Again, search YouTube for a comparable video. It might help. Not sure what your inital issue is with the capslock-only blinking, but they do have a code search somewhere on this site. Search for 'laptop diagnostic codes' and you should find something that might explain what its doing.

Compaq CQ58 blinking caps lock

Hi all,
I have a compaq CQ58 which has just been restored to factory settings and everything seems to be working fine.
However, my caps lock keeps blinking 3 every second and then a break of about 2 maybe 4 seconds.
I can't find reference any details regarding this. All I could find is blinking caps lock and booting issues. This does not apply to me as laptops works as normal.
Not too sure but this might be related. I have removed the screen due to being smashed and laptop carrently runs on external screen while I'm waiting for a new screen.
Could someone advice please.
Thanks a lot.

Hi lokyt,
I see that your Compaq has a blinking Caps Lock light. Unfortunately, this blink code is an indication of a hardware issue. According to this HP document Computer Does Not Turn On and the LEDs Blink three blinks mean that it is a memory failure.
You can try removing and then reseating the memory. Here is the Maintenance and Service Guide for your model on page 36 you will find instructions on how to remove the memory. You will also find replacement part numbers if you need to replace the memory.

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.

Pavilion Dv5-1009el - Black screen and blink caps lock and block scorr

Hi,
I just replaced the motherboard of my pavilion that reported an error as object. The purchased motherboard is new and hp original.
After having changed, I turn on the pc and work fine, i see the hp logo and enter to bios, after I turned off the pc without starting windows.
I inserted the battery and powered on the pc and returns to the old error, the LED of caps lock and block Lock blinks...
So I tried to update the bios from USB using winkey + B. The computer emits two beeps but does not read from any USB port and the LEDs go out for a while and then blink again.
What can I do?
Greetings,
Enzo.

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.

G62 fans run, black screen, blinking CAps Lock

I went to turn on my G62 today and i heard the fan running and it tried to boot up but stopped. The screen was completely black and the caps lock key blinks steady one blink every like 5 seconds.
It was running perfectly fine yesterday!
Someone told me it sounds like a bios problem but when i searched the forum for a fix it said to start it up while holding the windows and B keys and turning it on. This didnt do anything and now i need a fix?
Anyone that can help it would be appreciated greatly!

Hard reset fixes issue.
But still do it again as follows:
1) Turn off laptop.
2) Remove battery and AC plug.
3) Press and hold Power button for 1 minute, do it thrice.
4) Now put battery and plug AC.
5) Now press power button.
6) Go to BIOS settings and reset all.
Above worked for me.

HP Dv6z-7200 Notebook blinking caps lock key, red wifi button

I re-did the thermal paste on my computer (Dv6z-7200, AMD A10-4600m, Radeon 7670m, 6Gb RAM ) and i put it back together, and the screen does not come on, the power button lights up, the wifi key is red and then the caps lock key blinks indefinetly, and the fan comes on. Lucky for me my buddy has the same laptop so I took out the motherboard on mine and put it in his' with his' hard drive, RAM, wlan, etc. and it still didn't work. So it must be the motherboard, right? Could it be something with the BIOS? If it is the motherboard that is fried, could someone direct me to where i can get a new one? I tried the hp part surfer website, but could not find it. Thank you -Zach

Hi Nayj424,
Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your Compaq Presario CQ62-102TX Notebook and getting a blank or black screen on startup. Try performing a hard reset. When performing a hard reset please note remove any and all USB devices, and remove memory cards from the card reader slot. Disconnect all non-essential devices. If that does not help try to turn on the computer you start to press F11 repeatedly till the menu opens. You can do a system restore.
Hope this is helpful.
Thanks.

HP G42-475DX Blinking Caps Lock

Good Day
I currently have an HP G42-475dx which was purchased about a year and a half ago. This laptop has known to run fairly hot (around 80 degrees celcius).
I was using the laptop to play music, while the screen went blank. I took off the laptop.
1st - Upon putting on the laptop, the caps lock LED blinked twice (Indicates corrupted bios). I then went to power off, and leave it off for 10 minutes.
2nd - Upon leaving off for a while, the caps lock is now blinking 5 times upon powering on (General system board failure). I then proceeded to open up the laptop and remove the CMOS battery.
Upon removing the battery, and leaving the laptop off overnight.. The caps lock is now blinking once, (which indicates CPU not functional.)
I am unsure whether the motherboard has gone bad, or if its just the CPU itself. I need to get this laptop back and running for when i start school..
Any help would be appreciated.. Thanks!

It's most likely the motherboard or a corrupt BIOS. CPUs rarely fail.

G42-415dx single blink caps lock - options

My beloved G42 has bit the dust. I get nothing on the screen. The light on the caps lock key is doing the single blink. HP docs says this is the code for bad CPU.
I tried blowing out dust.
I tried unplugging, removing battery, holding power button 15 seconds, plug in and leave battery out and then turn on.
I tried removing the RAM
I've done every troubleshooting step I could find and it still gives me the single blink and doesn't boot.
1) is there anything else I should try?
2) Can I fix this myself by replacing the CPU?
Thank you

HPG72-250US Power Light Blinks, Caps Lock Light Stays On

So I have been having some problems with my computer, an HP G72-250US, that I bought a few years ago. Namely, the screen would get black and white lines on it and freeze: Here's a pic. What the screen looks like.
A friend of mine told me that it could be a problem with the fan, so I decided I would try to take it apart. After some success, I noticed the fan wasn't clogged or anything, so I put it back together. When I did, the power button only turns on for a half a second, then shuts off. It repeats this over and over again. I noticed that the Caps Lock light stays on. Doesn't blink, doesn't do anything.
I looked around online (using my wifes computer) and all I could find was the HP LED error codes, which mention the Caps Lock or Number Lock light blinking, but nothing about the Power Button Light. Could it be the same issue, a CPU failure?
Thanks for any help!
UPDATE:
So after watching my computer for a bit, the Caps Lock Light DOES do something. I hope I can say this correctly so everyone can understand it:
The Caps Lock Light is on, the Power Button Light is off. For the split second or two that the Power Button Light comes on, the Caps Lock Light goes out. The LAN connector also lights up when the Power Button Light is on. Everything is pointing to it blinking once, so I'm still thinking its a CPU problem. Any thoughts?

When a turn the computer off, the caps lock light on my keyboard turns on, only to turn off after I strat my computer.
You might consider zapping your PRAM.

Hi Suzieg,
I understand you’re getting a blank display when you turn on your laptop.
You mentioned the caps lock light blinking when you turn the computer on. Here is a link that will allow you to check and see if the blinking of those lights on the notebook, match what you see in this link . A lot of the time the lights can blink in a certain pattern, I would like you to take a look at the listing of blink codes and let me know if the laptop lights are blinking in that nature.
When you open the link go down to the section titled “ LED's near Caps Lock and Number Lock keys blink when starting notebook”.
Please respond back with your results.
Thanks

T440s: No on screen display of caps lock, volume, screen brightness, etc.

Hello all-
I updated the BIOS to 2.26 a while ago and ever since then there's no on-screen indication of caps lock on/off, screen brightness or volume when I change it. Since it seemed to be affected by BIOS, I updated again to 2.27 just now, but the problem persists. Any ideas? Thanks in advance for the help.
EDIT: Just fixed my own problem. I needed to update the Hotkeys Feature Integration by downloading the utility thingy from this page. Probably wasn't a BIOS thing after all.
Solved!

Hi Brightnsalty,
Welcome to Lenovo Community!
As per your query we understood that you were facing issue with On Screen Display earlier on ThinkPad T440s.
And we glad to hear that the issue has been resolved after installing Hot key feature application.
I also suggest you to update Lenovo power management application, if the OS is Windows 7, please update Lenovo Power Manager application.
Cheers!

Msi p67a-gd65 mouse and keyboard freeze - blinking caps lock.

As the title says, my mouse and keyboard suddenly froze while I was chatting on Skype and I noticed that my system was still running. In fact, my razer mouse light was also blinking. The caps lock had a sort of sequential blink, although I'm not sure.
Anyway, I had to use the power button to shut down the system and everything seems normal again. Does anyone know what would cause this? Is it a software issue or due to my board?
I'm running 64-bit Windows 7 Ultimate.

p67a-gd65 motherboard
Intel i7 2600K
2x MSI 6970 graphic cards
Seasonic SS-850HT 850W PSU
G.SKILL Ripjaws X Series 8GB (2 x 4GB)
ADATA S599 system hard drive
ADESSO keyboard and Razer Deathadder mouse
This was the first time this sort of thing has happened. I did have to replace (RMA) my PSU once before due to a random shut down issue but that was resolved. I'm really curious as to why this would happen and I'm hoping it's a software issue and not something related to the USB ports on the board.

[SOLVED]Blinking Caps lock LED

Hello,
I'm a linux noobie and I've only been using Archlinux for less than a week, I'm quite liking it.
The other day I was able to compile a xenomai patched and an unpatched 2.6.25 kernel that boots up.
I restarted from scratch again,(to get familiar with the process) reinstalled Archlinux, and then tried to compile my own kernel again, but this time I only get a flashing capslock LED and a blank screen. I tried numerous reconfiguration and recomplie but I still get the same. What does the blinking LED indicates?
I also get this with mkinitcpio:
tho I think it's not needed since I configure the drivers to be in the kernel.
:: Begin build
ERROR: module 'pata[-_]sis' not found
ERROR: module 'ata[-_]generic' not found
ERROR: module 'scsi[-_]mod' not found
ERROR: module 'ide[-_]disk' not found
I added the ide_disk, the last time I was able to compile It couldn't see the disk.

EDIT:
compilation is on P4 asus mobo.

I did make use of mkinitcpio, I eliminated a couple of errors, but still got these:

I generated the image anyway, and edited grub to add initrd.
Is there a way to extrac the original Kconfig file from the CD, I think I may have corrupted the original, I mean it's not original anymore

btw, my disks are IDE's (pata?)
