Won't boot, Caps Lock light blinking, black screen, tried everything I could.

Hello!This is a problem that even made me scratch my head. It started two days ago: blinking light, black screen etc. (It was double-blinking, which mean't BIOS corruption). I looked around the HP forums for help and tried what I could find (keyboard combination, making a recovery disc out of a memory stick, which failed), but nothing worked. This sorta thing has happened before, but somehow it managed to revive itself, so naturally I ignored it, because I didn't expect what was to happen next, which is right now. Incase I can't get any help from here, I'm gonna buy an new motherboard, but what I am really expecting for is that the fix will not hurt my wallet and not buying a new motherboard. Hoping to get a response as soon as possible and not this to be overlooked. Perhaps this post will help other people in the future (Who knows?). Anyway, thank you for your attention.

Hi , Thank you all for visiting the HP Support Forums and Welcome. It is a great site for information and questions. I have looked into your issue about your HP Pavilion dv6-7000sy Notebook and startup issues. Here is a link to computer will not start. I would start at the top and work my way down. Mine was fixed with reseating the HDD. Others have had it fixed with just reseating the Memory. Here is a video that shows you how to remove and reseat the HDD and memory. Please note remove any and all USB devices. Disconnect all non-essential devices, as these could cause some issues. You could reset the BIOS with this document selecting the reloading the BIOS default settings. Which has helped others as it restores the default settings. If you should get the system started again, I would run the HP PC Hardware Diagnostics, It will tell you if something is failing. I hope something here helps any one of you fix the Notebook. Thanks.

Envy M6 Won't Boot, Caps Lock Blinks Twice

     My wife's laptop automatically installed some HP updates Thursday. After they installed, the laptop rebooted but only completed the shutdown portion. During the bootup portion, it never POSTs. It just sits there, blank screen, fan whirring, wireless radio light on (orange) and the caps lock light blinking twice every 4 or 5 seconds. I've also noticed that when I have a thumb drive in one of the USB ports, it powers up even when the laptop is off. And when I turn the laptop on, I see access flashes on thumb drive.
     I've tried disconnected the batteries, laptop and CMOS, with no luck. I've tried the hard reset procedure (WIN + B and then hold power for a second), with no luck. When I removed both sticks of RAM, it beeped properly.
     What options are available to me?

Hi @J1mM ,
Thank you for visiting the HP Support Forums and Welcome. I have read about your HP ENVY TouchSmart m6-k022dx Sleekbook and getting a blank or black screen on startup after updating. Try performing a hard reset.
When performing a hard reset please note remove any and all USB devices. Disconnect all non-essential devices.
You can do a system restore. System restore will help if something automatically updated and did not go well on the Notebook.
Here is a link to computer won't start for Windows 8.
If that does not help at the end of the document it shows you to do a hardware test.

Caps Lock Light Blinking Twice

hi everyone,
I have a hp Pavilion dm4-3011Tx with beats which is about 7 months old. Yesterday I woke it up from sleep and the keyboard lit up and the caps lock light would blink twice every few seconds. I held the power button down and rebooted it and when it started up the fans were running and the light was still blinking. I tried a hard reset and everything and several hours later it started again randomly...A short while later it happened again and this time I was unable to fix the problem. I have already read that it a Bios corruption but I don't know what that means. Can anyone help? Thanks. I have already tried doing a hard reset, taking the battery and the plug out, pressing the windows key and b while turning it on. Any help would be appreciated.
Thanks.

This is for anyone who reads this forum in the future. A corrupt bios fix can be simple or a pain in the butt so stay calm and patient. I've read forum after forum and had any luck with any of the suggestions people have come up with. One way(the easy way) is to power down if you havent already. Remove the battery, and charger if plugged in. Then hold the power button for 30sec, this drain the laptop of any excess life in the computer. Once done, place the battery back in its designated place, and connect charger again if needed. I've heard this has fixed some peoples issues. If you're having my luck, it will be a little harder to fix. Nothing I read helped at all, so i had to rely on my own smarts. Now I'm saying this will work for anyone, but it did for me, so you can try, but im not responsible for any problems you may cause or come across because of it. This should only be done by someone with some computer know-how. What i did was remove the bottom cover of the laptop so i could get to the motherboard and other components. (Make sure power source is removed) This will take time, so be patient and be careful. You dont want stress any cables or circuitry inside the computer. Once you remove the cover, look for a small circular li-ion battery, this is called the CMOS Battery. This is the battery that powers your motherboard while the laptop itself is powered down. So while one would think that having your laptop off for long periods of time is fine, youre actually using up energy stored inside that small battery. Once you locate the CMOS Battery, remove it from the motherboard, remember to be careful though. Now wait about 30sec, thats what i did at least. Once time has passed, put the battery back in its place. After that re-place the the cover and anything else you may have removed. Once done, re-place the battery and/or charger and power on. This is what worked for me, it may or may not work for you, but let me know if it helped or if you have any other questions. Good luck everyone!

42RV535U won't boot. Yellow light blinks 3 times.

The title mostly says it all. After a power outage ( AC disconnected ), my 42RV535U won't boot. The yellow light keeps blinking 3 times.
I have tried disconnecting, waiting, then reconnecting the power and have tried different outlets.
Any ideas of what I can do to get it to boot, or to further debug/diagnose the problem?

If you can't solve your issue and no one in the community can help, contact support to speak with a tech support agent at (800) 631-3811.

Won't boot up - sleep light blinking 3 times

Hi - I have a macbookpro - it suddenly shut down and now won't boot up. When I press the power button I hear the hardrive make a noise " tzz tzz' then nothing - except the sleep light is blinking 3 times a second every few seconds. - I've tried taking out the battery and holding down the power button - taken out the RAM - nothing.
and of course my 90 day warranty ran out last week -
Help gratefully appreciated....

Hi - Thanks for your reply, I had a look round the net and found that diagnosis - I don't think it's applicable to me as the machine was up and running to start with. My girlfriend was ill in bed and watching a dvd - could this have overheated the machine and are the 3 flashes to do with this? I've since found this
http://static.scribd.com/docs/1ek00bgxjmm4u.swf?INITIAL_VIEW=width
which says it could be down to overheating - if so is there a way to reboot or is it a trip to the mac store ??

Won't boot at all, just a black screen

I have a HP G72-227WM Notebook PC. Windows 7 64-bit. It recently crapped out on me. I have no idea what went wrong on it. All it does it go to a black screen as soon as I turn it on. No logos, no cursor, just straight to a black screen. The fan spins, and it sounds like it's going to boot up, but nothing happens. I did not install or uninstall anything prior to this. I was burning CDs in Windows Media Player, it was cancelling the CDs about halfway through. So I put it up to look at it later. When I took it back out, all I got was a black screen. I just ordered the System Recovery CDs through HP, but nothing happens when I put them in either. They spin and sound like it's loading, but I still just get the black screen. No function keys work either, not F8, F9, or F11. I really don't think it's a problem with the screen, just wondering what I should try next. Thanks

This time try to reinstall the OS with help Of CDs
Use the recovery disc to restore the PC by following the steps below.
Insert the recovery disc in the optical disc drive and start the computer.
If the computer is running, insert the recovery disc and immediately click Start and select Restart to force the computer to start from the recovery disc.
When prompted, Press any key to boot from CD or DVD, press any key on the keyboard.
Allow the recovery disc to start and load the required files while the Microsoft loading screen is displayed. It may take several minutes to load the required files.
When the HP Recovery Manager window displays, click System recovery .
Follow the on-screen instructions and perform the required actions.
NOTE:Do not interrupt the recovery process even though the computer may restart, or the Windows desktop may display, or the process may appear to pause for several minutes at various times.
When prompted, follow the on-screen instructions to back up the user files.
After performing the backup, when prompted, re-insert the recovery disc, and then click Next to continue the recovery process.
A status box is displayed to indicate the status of the recovery and the estimated time remaining.
If you used multiple discs when you created the personalized recovery discs, follow the prompts to remove the first disc and insert any requested discs.
When prompted to Insert the Supplemental driver disc , take one of the following actions:
If you purchased a replacement recovery disc from HP, and it included a Supplemental driver disc, insert the disc and click OK or Next . The recovery program checks the supplemental disc and installs the specific needed files.
After the Supplemental files are installed, a prompt is displayed to remove the Supplemental disc and insert the original recovery disc.
If you purchased a replacement recovery disc from HP, and it did not include a Supplemental driver disc, click Skip or Cancel . The recovery program will ignore the request and install the next file on the recovery disc.
If you created a personal recovery disc, press Next to continue.
Continue following the on-screen instructions to complete the recovery process.

[SOLVED] Arch won't boot after install - "GRUB" on black screen

I've installed arch on my 1000H from usb stick using zeneee kernel as described in wiki. Right after install everything was fine - wireless and ethernet were working normally, so i've done reboot.
Now it shows me black screen with "GRUB" text (sic! not "grub>", no error messages) on it. keyboard is not working.
I've tried reinstalling completely again - with full repartitioning of HDD and this time without installing eee kernel - just stock kernel26. Everithing went ok, i've checked grub settings and partitions - ok, but after reboot - again "GRUB" and non-working keyboard.
I'm completely out of ideas.
EDIT: turns out i misplaced GRUB or something. reinstalled placing GRUB on /dev/sda. works fine now.

Have you moved everything from /var to /new_var (i named it for learning purpose)? You shoud copy content from /var but not on the fly but booting from arch iso cd, and than you shoud mount your / into arch-chroot environement, mount all of your mount points and than copy content from default /var to new /var. The copying should be done with this
cp -rax
and you can add -v switch to verbose output. I have my own /var moved the same way.
The simples way is:
-boot the arch iso cd
-mount all of your mount point (i created here in this step /new_var to move /var to a new place, and this /new_var i put in /etc/fstab as /var later)
-copy /var to /new_var with -rax or -vrax (recursive, archive, this filesystem or verbose, recursive, archive, this filesystem switches)
-umount all of it
-reboot.

Won't boot. Gong sound and Black screen alternate over and over and over.

So yesterday, on a Mac Pro (newer, came with slim keyboarboard) I tried to launch iPhoto. The Icon bounced as though it was opening like 4 different times then suddenly the screen dropped to a really low resolution (i could tell by the size of the cursor) and all blue. Nothing would save it, so I forced it to shut down. Now, when trying to boot it cycles between the gong and a black screen. Over, and over. Even when booting from a disk. If I hold down option it will take me to the screen to select a drive/disk/partition to boot from, but as soon as one is selected: black, gong, black, gong, etc.
I think it's important to note that this bad boy is equipped with Faronics Deep Freeze. It's had problems 3 times within the past month or so, where a clean re-image is necessary. Any ideas on the problem would be great!

Hi Riley Florence;
I hope you have a back up because it sounds like your hard drive has given up. I suggest that it time for it to go back to Apple.
After reading some of the reviews on Faronica Deep Freeze and its security vulnerabilities, I am not going to install it on any of my Macs.

FM2-A55M-E33 won't boot if LAN cable fitted, black screen with 99 in rh corner

Just bought a new Zoostorm 7872-1212/A computer, which has the MSI FM2-A55M-E33 motherboard.
I installed and registered Windows 7, and download all updates etc without any problems last night.
Started it up this morning, and it didn't post.
All I had was a black screen, with 99 in the bottom right corner.
Switched off, then tried again, still no joy.
Removed all cables, re-fitted just mouse, keyboard and monitor, and it started.
Powered of and refitted LAN cable.
Powered on - black screen and 99.
Powered off, bought new LAN cable, fitted it into another port on my router, powered up, black screen and 99.
Thinking it's a BIOS setting, opened BIOS
Set Sata drive as 1st drive, DVD as 2nd and disabled all other drives
Set wake up events to BIOS, RTC disabled, all other events on
Saved and powered of
Started up, and still back screen and 99
Anybody got thoughts?

Black Screen - Tried Everything. Broken?

I put my intel iMac to sleep last night. This morning, I go to wake it up, and it makes all the right sounds, but nothing displays on the screen. It is pitch black.
I've tried rebooting, clearing the PRAM, booting into the restore DVD and completely powering the iMac off and then back on. Nothing has worked, the screen is still pitch black.
Is it safe to say that it is broken and I need to get my iMac serviced?
Thanks.

hi,
i experienced the black screen today on my 24" imac
i tried everything and while searching i found this thread.
well, i put the imac into target disk mode and connected my ibook... unfortunately, i don't have the capacity to backup my data but was nice to see my files/folders.
i disconnected the imac and left it powered on.
a few minutes later the firewire screen saver was being displayed on my imac's screen!!!
i turned it off and powered it up again with no problems.
we had to leave so i powered off the imac and when i returned, over a hour later, and powered it up - no joy.
so, back to target disk mode and waited for the firewire screen saver to kick in.
once the screen saver kicked in i turned off and powered up again.
i'm writing this while i'm backing up my files/folders to an external drive!!!
i hope this helps someone.
i plan to reinstall the OS from scratch and go from there... i had been downloading installing software the last few days so i'm hoping for some kind of software conflict.
if it continues i'll bring it in for repair.
applecare anyone - lol????

Black Screen - Tried Everything

I have a black screen, you've encountered these before, I know that. I have tried to reset firmware, reset PRAM, unplug everything and hold power button for 5 seconds, then replug everything in. I've tried everything, and I'm proficent in Macs, but not really in Darwin or Terminal. If it helps, I fsck -f the disc to delete a stubborn help file in a Photoshop trial, which was the last time I restarted. I held off on the SMF update, because I didn't show any examples of it happening, until today. So, nothing has worked, and I need all this data. Thanks for all the help.
If there is anything else I can try, by all means, do tell.
Also, if I need to ship it off or bring it somewhere, will I have to do it after the holidays?
Thanks again.
Oh, I don't here a chime, and I need to use a credit card to eject the firmware disc.

Only other thing I could suggest is re-seating the ram - may not help but it's worth a try. As for the holidays I'd give them a call before just to see what the wait may be like ...I'm sure it varies from place to place.
Does holding the trackpad down eject the disc?

Balnk scrren, blinking caps lock light

This question was solved.

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.

Hi wasasa45 ,
I am sorry to hear about this issue.
At first, please 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 30 seconds. Re-insert the battery, plug in the AC Adapter and start the notebook.
If the above step does not help please refer to the follwing document:
Computer does not start (Windows 7, Vista, XP): http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01443371&cc=ad&dlc=en&lc=en&jumpid=reg_r1002_us...
Please follow the steps in the section that says "Symptom: LEDs glow, fan noise is heard, but display is black or blank".
If the above step does not make any difference, we will go ahead and reseat the Memory (RAM) and the Hard Drive (HDD) on the Notebook and see whether that makes a difference.
Reseating RAM:
First we will have to try reseating the RAM. Your Notebook should have 2 RAM slots. If you have got a single RAM Module, you can try removing that from the existing slot and place it on the other one and see whether the Notebook turns ON after that. If you have got two Modules, you can try swapping them. If that too does not work, try turning ON the Notebook with only 1 Module inserted and also by changing the slot. You will have to work the permutations and see whether the Notebook turns ON. This is to understand whether the issue is with any of the RAM slots or the RAM module itself.
Please find details on how to reseat and insert back the RAM from the following document:
General document on Steps for Removing and Replacing Memory Modules:http://h10025.www1.hp.com/ewfrf/wc/document?cc=uk&lc=en&dlc=en&docname=c00262554
Reseating HDD
We will reseat the Hard Drive cables and will put it back to its actual position.
General document on Steps for Removing and Replacing the Hard Disk Drive: http://h10025.www1.hp.com/ewfrf/wc/document?cc=uk&lc=en&dlc=en&docname=c00649950
You just have to reseat the Hard Drive cable and then insert it back to its actual position. This is to ensure there is no loose connection or static electricity accumulation. Check whether the Notebook works properly after doing this.
I am waiting to hear back from you.
