Failure to Boot Up, HP dv4-1225dx BLACK SCREEN Blinking Caps/Num Lock

HP,
Since yesterday, my laptop has been unable to start up, at all. When I turn on the power button, the fans start to run, but there is no backlight on the monitor at all, just the audio system on the keyboard with continous blinking lights on both Caps Lock and Num Lock. These lights continue to blink forever until I am forced to shut the computer off.
The HP model is Dv4-1225dx, was running Vista.
Could I get some help to resolve this problem?
Thanks!

Hi,
 Although I hope you already resolved this issue I do have a temporary; possibly perminate solution. I read an article that sounds ridiculous, but it worked for me. Cover your pc with towels to block all air flow. Just leave the screen open so you can see it. MONITER THIS CLOSELY!! After 20 minutes or so it should turn on. Log in and back up what you can just in case. You also want to let the pc run a while to cool down. Shut down and let cool for at least an hour. Try to boot up. If you cant now repeat the above. It may take more than 1 try.
Hope this helps someone. Please also remember, this isnt a perminate fix but its better than junking your pc!

  • 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.

  • Apples update didn't work for me: Boot Camp: iMac displays a black screen during installation of Windows 7

    Boot Camp: iMac displays a black screen during installation of Windows 7 - Apple Support
    I have followed each of the steps listed in the link above with no success.
    Prior to adding the extra drivers I was able to start the Windows install process up to reformatting the "Windows" Bootcamp drive. After that the computer would go through some instal processes and eventually restart. After the restart the screen would go black. The black screen lead me to the  Apple Support link above dated March 5 2015. After going through steps listed in the link above, I get an error message stating that the D:\Sources\instal.win. file cannot be located. I am forced to restart the computer at that point and theWindows install process attempts to start again but always ends up at the same point.
    Note: I am installing windows 7 Pro from a DVD. I scanned the AutoUnattend.xml file and noticed that it refers to "Windows 7 ULTIMATE" but not "Pro" or any others that I could see. (see below). Could that be part of the issue?
    Any feedback would be greatly appreciated.

    The W7-Home Basic .clg file will have 5 entries, with 'Y','Y','N','N','N'.
    This allows a single .wim Image file on the DVD media to be used to install any of the 5 flavors of Windows. When you enter your product key, the Installer knows what specific W7 variant you have the key for and will tell the WIM to extract the specific files the installer needs to be extracted.
    The following line
    <cpi:offlineImage cpi:source="wim:d:/sources/install.wim#Windows 7 ULTIMATE" xmlns:cpi="urn:schemas-microsoft-com:cpi" />
    is telling that a retail product key will be entered, which should go look for this specific .clg file (from the five you already have on disk).  You can test if it will work for you by changing this line to the following
    <cpi:offlineImage cpi:source="wim:d:/sources/install.wim#Windows 7 PROFESSIONAL" xmlns:cpi="urn:schemas-microsoft-com:cpi" />
    If it does not work, the other issue can be related to device discovery. Typically A: and B: device names are reserved for Floppy Drives. C: is your internal HDD.
    D: can either point to the Optical drive, or the USB. The normal convention is that the removable media is named from Z: backwards. Y: and Z: are usually used for Network drives, so X: should be your USB. First try with the change to "Professional". If it does not work,

  • HP Pavilion DV7-1428ca _ CAPS + NUM LOCK Continually Blinks + Will not Start up Black Screen

    Would appreciate any suggestions on the issue I am encountering.
    I have an HP Pavilion DV7-1428ca that was left powered on, so it went into Safe mode (screen goes blank). Once I came back to my Laptop hitting any key would take out of of the Safe mode however this time it did not. It remained with black screen irregardless of buttons pressed.
    Had booted and can hear the fan and hdd go for the 2secs then it stops to a Black Screen with the "CAPS + NUM LOCK" Continually Blinking. Tried to Hard Boot several times but the same thing re-occurs.
    It does not seem to be blinking in a series a code, just a steady blink (every sec) for both the CAPS + NUM Lock for as long as I leave it on. HP Site provides a chart from 1-6 series of blink codes which does not seem to apply to me.
    Being out of Warranty I am hesitant in bringing it to a local repair shop without trying any alternate trouble shooting first.
    Thanks

    Hi,
    First of all, shutdown the notebook, unplug the AC Adapter unplugged, remove the battery, and then hold down the Power button for a full minute.  Plug in the AC Adapter ( leave the battery out ) and see if the notebook will start.

  • MSI GT683R Black screen, blinking cursor

    Hello, I was poking around for a similar topic but couldn't find one, so here I am.
    Mine is an MSI GT683 laptop; it’s about four months old and second hand. When I boot it up, I see the MSI screen, and then I see a black screen with a blinking underscore cursor.
    I’m pretty sure this is my fault, because when it arrived I decided I wasn’t satisfied with how it was setup (plus it had lots of stuff left over from the previous owner) and I reformatted and reinstalled Windows 7 on it. It booted up great the last time I used it; I installed all the updates, installed all the drivers, restarted it a couple times, and it was working like a charm. I even put a couple games on it. Then I put it into hibernation and left it alone for a day, and now I have the blinking black screen cursor of evil.
    This is what I’ve tried so far:
    1) I can’t get into the BIOS. When I restart, it doesn’t say “Press such and such to get into the BIOS!”, and nothing I press works (I thought MSI used Del, but in a fit of maadfobdogbd I also tried lots of other keys.) For that matter, I also can’t get into safe mode.
    2) As far as I know there’s nothing wrong with the keyboard. I can actually adjust screen brightness with it. There’s nothing connected to the computer.
    3) The Windows OS CD doesn’t work. It seems to think about using it, and whirrs around with it for a bit, but I never get anywhere other than black screen, blinking cursor. I’ve tried both Windows 7 and Windows XP, but nope.
    4) I think my Windows 7 version may be x86. However, since it was running smoothly enough, I don't really think it was an issue.
    Sorry for the trouble; hope you can help!

    Boot disks don't work, either. Actually, this thread here shows my exact problem, and the answer sounds pretty plausible, given how I put the laptop into hibernation. Unfortunately, that guy never got it fixed. :<
    https://forum-en.msi.com/index.php?topic=149961.0
    I haven't gone so far as to take it apart yet. (I'm kinda leery of taking laptops apart. The last time I did it, I had to get stuff into this really awkward little space where I had no finger strength, and in the end I had to call a boy to snap the thing in for me. It was embarrassing.) I'm going to try swapping in another hard drive with Windows on it. I'll let you know how it goes.
    EDIT: Alright! So it worked! Well, kinda. I got into the BIOS but it looks like my installation might be dead. I don't care a lot about the installation anyway, so while I'm going to try to fix it I may just reinstall everything... again.
    I couldn’t get into the BIOS because it was apparently switched off for hibernation. What I did was that I dug up my giant box of computer parts and found an old hard drive that had Windows installed on it. I'm told that I should have swapped hard drives out (and I probably would have eventually), but just using a USB port worked for me. My laptop wouldn’t boot from a USB boot disk or from a CD, but it did find and boot from another hard drive, so I finally managed to shut it down properly.
    I’m still getting black screen of blinking cursor evil, but this is progress. Still looking out for help.

  • N770 TF 2GD5/OC Gaming black screen blinking problem

    Hello there,
    i upgraded my PC 4 days ago with a MSI N770 TF 2GD5/OC Gaming graphic card. I installed the newest graphic drivers. Clean install and without nVidia Experience. My problem is black screen blinking when i am playing or watching. Screen turns to black for 1-5 seconds like monitor lost its signal. It happening when i click to fullscreen button. No matter if its in youtube or windows. It happening every time. It does the same when i am playing. Big lag and then black screen blinking for 10 sec. Sometimes more sometimes less than 10 sec. I used Google and i am not the only one, who have this problem. Some people says, that GPU BIOS flash helped but in MSI website is only one BIOS and i dont know if its newer than mine or not. S/N of my card is 602-V282-380B1404100829 (if it helps) and my current bios is here h t t p ://leteckaposta.cz/186979270 (just click on the GK104.rom in the middle).  I think i tried almost everything. Registry clean, anti malware and spyware, drivers re-install, turn W Aero Off, UAC off and other worthless tips how to fix this issue. I monitored my PC with many temperature software and i am 100% sure, that overheating isnt the problem. So could you please check if the MSI Bios is newer than mine or tell me what to do to fix this irritating problem?
    Thank you very much
    PS: I am not a native speaker and english is my 3rd language tbh, so please excuse any grammar mistakes

    you are using latest vbios version, test the card in another PC

  • Nvidia drivers black screen blink

    I use nouveau drivers because at first install, nvidia ones didn't allow X to start at all. They work fine, compiz included.
    Now, I thought on giving nvidia ones a new oportunity, and they seemed to work fine, except for a weird black screen "blink" from time to time: when I log in, I see desktop background, then screen turns black for a second, then desktop and compiz load. When I load some web sites with flash in it, black screen for a second. It even happened once at nautilus open o_0
    I am pretty sure I correctly configured xorg.conf, 10-monitor.conf and 20-nvidia.conf, is this a common issue or did I missed something?
    BTW, video card is a Geforce 8400GS.

    Maybe this is related.

  • HP DV4-1155SE Black Screen and Wont Boot. Please Help!

    Hello all I am working on an Hp DV4-1155SE. I have tested the memory modules, the hard drive and everything else that I can take out of the computer easily. Everything works but!, The laptop will not boot into the bios or anything else. Black screen, wont boot and i have the bios file that HP supplies on the support page of the site. I have looked at the instructions that a few people have posted about re flashing the bios and that does not seem to help me at all with this AMD processor. If anyone can please offer any help at all this would be greatly appreciated.
    Thank you!

    I will search on int 19h....thanks.
    My problem started before the bios-screen.
    This is what I tried this evening:
    - Disconnected all non-essential devices...no effect.
    - Cleared the CMOS...system booted to OS!    Screens still garbled! 
    - Put in an older graphics-card...No artifacts! 
    - Put my MSI NX6600GT (AGP) back in...screen grabled while booting. Once in OS everything
      looks fine at first. Later I noticed some odd random pixels. Playing movies is working fine.
      Playing 3D games results in all kinds of strange looking artifacts.
    - Installed the latest NVidia- drivers...no effect.
    Is my problem still MOBO related or Graphics Adapter?
    Any further advice?
    Thanks!

  • Can't boot to windows, stuck at black screen (with cursor)

    Hi! I'll get straight to my problem: I can't boot to Windows (Windows 10 Technical Preview) anymore after installing VirtualBox (or rather, an Android emulator that installed VirtualBox) on my system. I get stuck, after the loading animation with the blue HP logo, on a black screen (I can move my cursor around) but the login screen never shows up.
    The problem.
    I'm currently dual-booting linux and windows for several purposes. My laptop came with a Windows 8.1 OS by default. Some time after the Windows 10 Tech Preview came out to public, I upgraded my system to Windows 10 (so my 8.1 is gone now). Everything's going well until I installed this Android emulator (which installed VirtualBox) on Windows 10. Everything seemed fine at first but after rebooting, Windows isn't working anymore. I can still boot to linux, but Windows just won't boot properly.
    What I've tried.
    I've tried A LOT of things. The problem actually happened twice already (at first I was able to fix it with System Restore but not this time around). I have a Windows 8 USB Recovery Drive at hand, just so I can access a Windows command line. It's not from my system, though. It came with a new windows 8 laptop of a friend so I just borrowed it.
    1: System Restore. This worked the first time. But now the restore won't finish and throws an error, telling me that it can't restore my system.
    2: Refresh PC. "There was a problem refreshing your PC. No changes were made." or something like that.
    3: chkdsk on C:\. It says it changed some files, but it doesn't really fix the problem.
    4: sfc /scannow. Again, something happened, but it didn't get fixed.
    5: bootrec.exe to fix BCD and MBR. Doesn't work. (as far as I know my sytem is using GPT)
    6: Hard reset (remove all power sources then hold power button). Still not working.
    7: System Restore again. All the restore points aren't working. It reaches a "Finished" state, but then an error comes up after. It says can't extract a specific file, and the restore point is damaged or might have been deleted during restore.
    8: checking and fixing bad sectors (nope, no bad sectors on my hard drive)
    9: built-in component tests. It passed all of them, except the battery test (my battery really isn't surviving for any duration longer than 30 minutes, but that shouldn't affect my OS). I didn't try the really long tests since I thought it wouldn't matter as my problem is most probably completely software (since linux is still working).
    10: cry. oh please. Windows isn't working. What should I do? (
    Things I haven't tried.
    1: RAM and CMOS battery reset.
    2: Reset PC.
    3: Format hard drive.
    4: Test hard drive on another laptop's system.
    If possible I'd like to avoid getting my hard drive wiped, since I have a lot of stuff to backup (more than 300 GB of files + dozens of linux apps and ppas), and I only have a 32GB USB drive to backup all the files I need).
    Thanks for reading.

    Sorry for the delay. Wasn't expecting the "road work" signs when attempting to check back with you in the AM here.
    As others have already mentioned, the prompt for file systems occurs during text mode setup. Quick or Full? FAT or NTFS? How do you know what to do?
    We'll start with file systems, short and sweet. Most any OS can read and write FAT volumes without fail which makes FAT ultra-portable, and the only choice if you want to let Mac OS write documents on your Windows volume. It's also more efficient on drives of 16 GB or less. However, FAT has no folder-level access control, so any file in the system can be manipulated by any user or by any system process. By contrast, NTFS is far more restrictive. It can only be manipulated under Windows, though other systems may be able to read it. Not only do you get the access control that FAT lacks, but you also get superior efficiency on large volumes, plus the power to compress or encrypt folders and files at will (in "business" flavors of Windows only--and yes, Vista Ultimate counts as "business" even though it will be supported much like a "consumer" version).
    On format speeds: A quick format is very handy if you have a large partition or a single drive completely dedicated to Windows. Because it completes in 30 seconds or less, it will go a long way toward completing your Windows install. However, in some cases, volumes formatted with a quick format may have reliability issues. They must have fixed this in Vista, because Vista can only format at the "quick" speed.
    A full format tests all blocks of a given volume (as opposed to testing an entire disk unless the volume itself is the entire disk) as the file system structure is laid down. Bad blocks are marked as "used" when they are found. This type of format takes much longer as a result of all the testing, but the result is a more stable volume from the start.
    Get past the formatting stage, and you'll be right as rain.

  • Windows boots but won't load (Black screen with cursor)

    [Sorry for the long post, but I feel the need to fully explain my situation]
    I have the following problem:
    I turn on my PC, and Windows shows it's normal loading screen, after which it goes into a completely black screen, with just the mouse in the middle. By the cursor size I can tell that it's in a low resolution, probably 800x600 (compared to my usual 1920x1080). I am able to move the mouse around, but with no particular use without something to click on. No other keyboard input seems to work, except for Shift key 5 times, which brings up the Sticky Keys dialog box (with just "Yes" or "No" options, no other link); and Windows key+U which brings up the Ease of Access center. Ctr+Alt+Del does NOT work.
    So far this is what I have tried (in chronological order):
    Boot into Safe Mode, Safe Mode with Networking, Safe Mode with Command Prompt, Booting in low resolution video, Last known good configuration: all yield the same result as booting normally.
    Repair your computer:
    Startup Repair: Found Registry Errors (I realized and fixed this later on)
    System Restore: Did not find any previous restore points (I know for sure that there are, I made a habit of making restore points regularly).
    Windows Memory Diagnostics: Did not find errors.
    Command prompt:
    Ran chkdsk /f /r command, did not report errors.
    Ran sfc /scannow : I don't remember the exact report, but it asked for a restart to finish repairing problems. I restarted, and ran the command again for the same result.
    Forced the scan with: sfc /scannow /offbootdir=c:\ /offwindir=c:\windows , it found and repaired some errors, still could not load windows.
    Ran Dell Startup Diagnostics, found no errors.
    Ran Startup Repair again, found the registry errors again. I found the solution to this in a Microsoft Help forum ( answers.microsoft.com/.../f77d5355-b8be-41d6-af24-cae994e1768f ), and fixed the issue. I rebooted, but the problem persists.
    Startup Repair now finds no errors. I tried System Restore again, it found 2 restore points dated AFTER my problem started. I decided to restore anyways, but neither of them worked.
    I ran Windows Defender Offline:
    Quick Scan: and found 2 threats and removed them.
    Full System Scan: found 4 more threats, removed 2 of them, the other two couldn't be removed because they were within an ISO file.
    I tried Steps 1, 2 and 3 again with no luck.
    With each step I am aware that I'm closer to having to reinstall Windows, so I decided to see if I could still access my HHDD to save my personal files. I made a Linux live CD (with Ubuntu), but I am having trouble mounting the drives, because they are in a RAID0 configuration. "sudo dmraid -s" gives the following error: "ERROR: isw: wrong number of devices in RAID set "isw_dbdffjficc_ARRAY0" [1/2] on /dev/sdb".
    Important Details:
    I changed my graphics card about 4 months ago (an Nvidia GTX 750ti for an ATI Radeon HD 6450), and I was told that I may be running short with the Power Supply. The new card asks for a minimum of 450W and I think my PSU is 460W. This may or may not have something to do with this issue, I have no idea.
    The RAID0 configuration of my 2 500GB Hard Drives brought me a lot of problems from day 1. One of the HDD would randomly fail (I am able to hear a different clicking sound when this happens), and the computer would crash. Upon startup, it would ask for a boot device. The Dell startup utility would then only recognize 1 of the drives, but would finish without errors. After a restart or two, all would be fine and windows would boot normally (aside from the usual error recovery screen) without any sign of corrupted data or anything. Like I said, this has been happening form the day my PC arrived, but restarting a couple of times always fixed it. As of now, both HHDD seem to be working fine, the Dell utility recognizes both of them, and does not find errors in any of them, and I can access any directory from the command prompt.
    Is there anything else I should try before reinstalling Windows?
    Before the install, I would really like to be able to recover my files (I have important documents from college), is there any way to do this?
    Sorry again for the extremely long post (and for any language errors, English is not my native language), and thanks in advance.

    Since you still haven't got your data from the drive(s). I would advise performing a Windows installation without formatting the drive... I don't like this solution but at this stage you have probably tried everything else.
    Use a Windows 7 Reinstallation DVD when installing ensure you select...
    Select Custom: Install Windows only (advanced)
    If you do not select any of the drive options and simply highlight the largest partition and select next:
    Windows will dump all the old installation files in the Windows.old folder

  • Windows 7 partition won't boot, hangs on black screen / blinking cursor

    Hi all,
    I just installed windows 7 home premium x64 on a new 100gb partition I made first with bootcamp assistant and then simply with disk utility the second time. I can't get windows to load however, it just sits forever at the black screen with blinking cursor at top left.
    I have tried the Bootrec.exe /Fixmbr
    bootrec.exe /Fix boot
    Bootrec.exe /rebuildbcd
    fix that is floating around to no avail. The rebuildbcd command yields 0 copies of windows installed but still ends successfully.
    i have spent the majority of my day trying to get this to work and have no leads left anymore. Please help!

    I HAVE SOLVED MY PROBLEM! Windows is running excellently on my Bootcamp partition.
    Taking a few steps back: I used Bootcamp to remove the disk utility partition, then remade it also using boot camp assistant. Ran the windows install, and this time instead of hanging endlessly on black or going back to step 1 after restarting, the install went all the way. I had to restart once when the computer hung on "starting windows" but it got back on track right after this.
    I think I must've fudged something with Disk utility before.
    Thank you so much for your help!

  • Boot camp installation attempt yields black screen, also phantom monitor

    Hey all,
    So... I went to install XP on my early 2008 MacBook Black. I've done it before, so I figured there wouldn't be any problems (I had previously removed it). Only, when I attempted to boot from the CD... it appeared to boot, and I heard the CD drive working, but all I got was a black screen. Not even a blinking cursor. I know the CD is fine as it works in virtual machines. I attempted to use my Vista disc on my MacBook just after this and got the same result: drive access sounds, but a black screen.
    Then I discovered another problem... my Mac has a phantom external display. I almost think that perhaps when I boot off a Windows CD, that perhaps it is trying to use a display which doesn't exist? I won't really be able to test it until I get home (I'm out at college) and can plug in my external display...
    I had an external display hooked up in a previous installation of OS X... I pulled over the settings from that previous installation via time machine after reinstalling. That would certainly explain the phantom display. What is not explained is why I can't get rid of it. I've been trashing the plists that other threads recommend, resetting the PRAM... nothing really works. Detect displays doesn't help either. I'm wondering just what I have to do to get my Mac to realize there is no external monitor. I've read numerous threads on this, all culminating in no avail. Any advice, anyone?

    I tried resetting SMC too... still nothing. I almost think I should try booting from OS X's install CD, and see if the phantom monitor exists there... if it does, then I know there's a hardware problem of some kind. If it's not there, then I should reinstall OS X, and pull stuff over from Time Machine manually instead of automatically this time. I'm guessing that if I pull over user accounts automatically that it will recreate the problem. My only problem with doing stuff manually is that I'll have to jump through a few hoops to get my iTunes library back.

  • Windows doesn't boot after removing Ubuntu: grub black screen

    I need help, thanks.

    Hi,
    as far as I know, Windows needs the bootableflag on it's systempartition - and sets this flag, in case it is not set - to boot up.
    Actually, I don't know any way to prevent Windows from "touching" the MBR except a MBR-Lock (sometimes called "Boot-Virus-Protection") in BIOS - seems to be not possible on your configuration (Macbook -> EFI/GUID-MBR-Hybrid and not BIOS/MBR).
    One way, to evade the drama of manually editing the MBR, would be letting the Windowsbootmanager load Grub.
    1.) copy the grub-bootsector of your /boot partition to a file in your window-systempartition.
    dd if=/dev/sdX of=arch.lin bs=512 count=1
    mount the windows system-partition and copy arch.lin to the root of the partition (C:\ ?)
    2.) adding a boot-entry to your windows-bootloader
    boot windows, and add the line C:\arch.lin="arch" to the %SYSTEMROOT%\boot.ini
    (this could probably also be done from linux while doing step 1)
    3.) modify the windows-bootloader to fit your needs:
    a) change timeout=0 to timeout=15 (or something like this)
    b) let timeout=0 untouched and change the default to grub (so the boot-way should be: mbr -> windows-loader -> grub -> linux/win)
    I am not 100% sure, if this works as intended. There are plenty of howtos on the internet dealing with the winbootloader -> grub stuff. maybe you should read one or two just to verify this.
    Regards

  • 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
