Dv7-4173 no boot, blinking caps lock

I have an HP DV7-4173us, running Windows 7 pro 64 bit.
Up to date, hardware is stock, very few problems in the year I've had it.
It was running well up until yesterday, when I pushed the power button to wake it up from hibernate mode.
Fans came on, caps light flashed once, then everything went queit. The caps lock light blinks once per second, and the f12 light is Amber. No other signs of life.
I did the power reset (remove battery, discharge by holding power button, wait, ac power only) and nothing changed. I removed, checked, and reseated the ram, wifi, and all drive connections. No change.
I suspect the cpu needs to be reseated; before I do surgery, does anyone here have any ideas?

I've been having the same problem with my laptop not coming out of hibernation. I used to periodically get it to work by trying various hard re-boots/re-sets, but it's been weeks of trying now with no luck. I even purchased a new battery since my original one held no charge on it's own. The new battery didn't help at all. Hoping someone has something to help!

OK, I installed a new CPU and fan, cleaned it all up, used artic silver, and also cleared the CMOS. Installed the latest bios. I got windows to boot, and run well. However the keyboard and touch pad didn't work regardless of what was tried (installed new drivers, windows driver, uninstalled, dos command prompts yada yada....I did it all still nothing) The ext mouse/keyboard work fine. It's probably a hardware issue, as the laptop keyboard/mouse doesn't even work in F2 diagnoistics mode. Everything has been disassembled and reassembled multiple times, new keyboard installed, contacts cleaned and positioned properly, etc.
The laptop keyboard does work in the BIOS settings scren, so perhaps it's not a hardware issue?
Anyways, I decided to run system recovery restoring it to out of the box state with no saving of any prevous files of any kind. At about 30% the system shuts down once the fan starts spinning fast (I suspect the CPU is getting too hot even though the laptop is raised and nothing blocking the fan exhaust holes) I tried to do a recovery twice, and still it failed.
Could I install a new heat sink, new mobo, and mess around with this until it all works? Sure. Could I repartition the hard drive so that only windows is installed an all the HP junk removed for easier faster use? Sure!
But why should I when I can just sell it as is and be done with HP. I bought this used for $300 and it worked for a good year without issues. I'll recoupe my losses selling it for $200 and be done with HP.

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.

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.

Laptop Won't Boot. Caps Lock Button Light Blinking

I just bought a HP Pavilion DM4-2015dx laptop a few days ago. Turning it on this morning, it won't boot and the Caps Lock light is blinking. I have searched the HP site and Google for a solution to the problem and have found nothing to tell me what the blinking light means or why it won't boot up. Does anyone have an idea of what the blinking light on the Caps Button means?

My laptop HP pavilion Dv6 - 7132TX had a problem of blank screen and caps lock key blinking. I bought the laptop on 28th Apr 2012 and just before completing a year, I was facing a problem of computer inadvertently not booting. It used to show black screen with wifi LED red, power button LED glowing, and caps lock key LED blinking. http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&docname=c01443366 On going to the above link, I tried to notice the number of blinks of caps lock key LED.Found that the blink count was an endless loop of 2 LED blinks. On checking in the above link, found that 2 blinks meant the problem was BIOS corruption failure. LEDs blink 2 times BIOSBIOS corruption failure(as found in the table in the above link) So I went on and found another link to find the BIOS upgrade on the same page , where it read, Step 3: Find and download BIOS updates Then followed to the link: http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?swlinkmsg=100&cc=us&dlc=en&docname=c00042629&lc=en&product=4057208 to download the driver. Downloaded the BIOS latest driver and installed it. It gave the same problem while restarting the laptop which was required to complete the bios installation. Link for the BIOS installation: http://ftp.hp.com/pub/softpaq/sp54501-55000/sp54629.exe However after several force shutdowns and reboots (since in my laptop the blank screen during bootup was inadvertent and random..) the installation could proceed and complete. After that voila.. Problem gone Hopefully it stays that way. Now next task on my mind is to fix the sleeping problem of my PC and the noise problem of the speakers. 1.Laptop does not sleep and goes into freeze mode with LEDS glowing and screen black.2.While the laptop speakers are on, they constantly make some background noise as if the speakers have a loose connection. However I got a clue that the problem is not with the connections but with the frequencies mismatch. Inherent problem of laptop architecture I suppose. However still wish to hear sounds clearly on my laptop. Had a good experience with HP with my earlier laptop from HP. However now things are changing I guess. Feel good that I could at least troubleshoot and save money. [Even gas is Rs. 84 per litre.] and more importantly time since I was working when I saw this problem and did not want to keep laptop powered on All the time just to avoid restart .

I am working on this laptop that was working fine last week. Now it will not display, no post beep and the caps lock button blinks constantly every 3 seconds. What can I check?
Thanks

Hi
Try a hard reset,
Disconnect all external devices first.
Remove power cord and battery
Press power button for 30 seconds
Reinstall only power cord for first startup.
Power on
If no response
Try to Enter BIOS setup by tapping/holding the F10 key immediately after powering on the laptop.
Use Diagnostics to test your hdd - extensive.
If you cannot get the system to power on,
Manual: http://h10032.www1.hp.com/ctg/Manual/c02642701.pdf
Try reseating the hard drive by disconnecting & reconnecting SATA cable gently & firmly
Try reseating memory module
Power on & check

Hp pavilion dv7-4171us not booting. blinking lights

Hi, I'm unsure as to whether I'm posting this in the correct section. My problem is the following: My computer doesn't turn on. (It was working fine last night.) I can hear the cooler, but nothing else. The caps lock blinks once, and F12 is on all the time. I read that that particular way of blinking means "CPU not functional", but I have no clue as to what to do with that information. I checked on the forum, and though I found the same problem, it was a different PC and the problem was not solved. I would like some help, and instructions on what to do. Thanks.Sol

Maybe... it depends on exactly why the drive has failed and how far gone it is.
You may be able to find an adapter that plugs into the sata hard drive and into a USB port on your laptop. Maybe TigerDirect.com or Ebay? Once you have the new hard drive installed and the operating system back in place, you can plug it in and try to access the drive through Windows Explorer.
If this doesn't work, and depending on how badly you need the files, you can download something like Hiren's Boot CD which has a number of tools in it that may allow you to access the data, but that may require a significant amount time and effort to understand and use the tools properly.

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
Aaron

hi abennear

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.
Troubleshooting Black Screen Displays with No Error Messages During Startup or Boot
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.

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.

Blinking caps lock key

Anybody know why my caps lock key has started blinking. It isn't blinking fast and I thought I was seeing things at first but it is flashing now and then.

If you were talking about an Atari ST I would say 100% keyboard fault, the keyboard on the ST is 'intelligent' and this is the way it tells you it gone faulty - maybe similar thing going on with yours ?

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?

It is not a real problem in the sense that is does not hinder me in my computer use, but it is something strange.
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.
