Black screen, slow input

Firefox upgraded to v33.0. At that point, input from the keyboard became extraordinarily slow and the browser pane would go black (as others have reported) as well as dropdown menus.
I deactivated hardware acceleration, rebooted, and upgraded the Intel HD 3000 graphics drivers without improvement. I cannot reset as I use Session Manager and don't want to lose the library of saved sessions.
At this point, I cannot use Firefox. Is there a way to revert to an earlier version to get back up to speed?
I am using: WIndows 7 Pro SP1 64-bit, Dell Latitude E6420, i7-2769QM, NVIDIA NVS 4200M.

Mozilla has released an updated Firefox version (33.0.1) that fixes the black screen problem.
If you are in Firefox and can see your menus, you can [[update Firefox to the latest version|update Firefox from the Help menu]]. Otherwise, you should go to https://www.mozilla.org/firefox/all/ using Internet Explorer or another browser and download the setup file for '''Firefox 33.0.1''' in your language.
See [[Firefox shows a black screen or blank screen after updating to 33]] for more information.
<sub> '''Note to CoryMH:''' I tried https://www.mozilla.org/firefox/new/ in SeaMonkey just now and it offered me the old version, Firefox Setup Stub 33.0.exe ! </sub>

  • 8120 Pearl Black Screen, Slow Red Blinking LED. Data Recovery?

    Hi,
    I've been tearing my hair out for the last four or five hours (a drop in the ocean compared to some people with the similar problem I've read about), but I haven't given up hope of recovered my data - I'll happily condemn the phone if I could get just 5 minutes to copy the memo pad files and voice notes! 
    ANYWAY, here's the story:
    My 8120 has been working fine.  I checked it, put it back in my pocket.  2 minutes later, I took it out and got the slow flashing red light.  I hadn't dont anything to it...no spilling, no knocking, no random button presses.  Nothing.  
    So I tried to plug it into the charger - that did nothing.  Same slow red LED flash and black screen.  After 5 minutes I plugged it into my computer, first with the battery, then without.  Exactly the same.  My computer recognises it as plugged in when the light is on, and unplugged when the light is off - I've read this is common.  
    I download Blackberry Desktop Software.  It kept giving me the message telling me to either hit retry or update every time the light came on.  Retry did nothing, so UPDATE it was.   This is where the interesting thing happens - it scans for software updates - this stops the phone flashing altogether and suggests I proceed with the update.  I would do this, except when it suggests I back-up/encrypt the backup, these options are grayed out.  My data is more important to me than the phone (I know, I'm an **bleep** for not backing up before, but what's not done is not done)  
    So, it appears if I do the update my phone will be wiped.  Can anyone confirm this? Then I installed the BlackBerry Desktop Manager, and clicked on the add/remove apps.   It did the same thing - seemd to recognise the phone and the LED went out.  It told me how much space I had left on the internal memory - 22.2mb. I saw the internal memory is 32mb, so so long as the operating system isn't 10.2mb, it would mean my data is still on there? 
    SO for now I've decided to plug it into the wall and leave it for a few hours to see what happens.  Can anyone think of anything else I can try? Is there any software or any other way I could rescue my Memopad and Voice Notes files? Sorry if this has been gone over again and again, but I don't know what else to do! 
    Many thanks,
    Andy.

    Hello andoak and welcome to the BlackBerry Support Community Forums.
    Usually, the black screen with the red LED blinking indicates there is a problem with the core software and it needs to be reloaded for functionality to resume.
    If you are reloading the software and the options are grayed out to back up that usually indicates the data is not able to be backed up.
    On a brighter side, if you saved your voice notes to your media card, they should still be there. As for the Memos, if you never backed up or synchronized with a desktop application, they are lost.
    If you have email accounts set up, after the software reload completes, resend your service books as shown in KB15402 to resume email. 
    Hope this helps.

  • My iMac 8.1 was slowing down and had permissions problems. I backed everything up, and then re-installed. Now all I get is a black screen. Power+D gives me a hardware error message: HDD-1336. Help!

    My iMac 8.1 (10.6.8 ) was slowing down and had recurrent permissions problems, mostly with Java. I backed everything up, and then re-installed from time machine. Now all I get is a black screen which says I need to reboot. Power+D gives me a hardware error message: 4 MOT/1/40000003: HDD-1336 or HDD-1327. When I reboot from the OSX CD and start disc utilities everything checks out OK. When I reload 10.5.2 from the OSX CD everything seems to work OK and no more permissions problems. But then I loose all my email and safari stuff. Anyone have any ideas short of going back to my old PC?

    No unfortunatley it's too old, you are referring to Target Display Mode which became avialble in 2009, your 2008 needs to have the HD replaced. I'd still do that if everything else is OK or you can simply buy a new MM and display or even a new iMac  or an Apple refurbished iMac to save money.

  • Black screen after login and slow NAL

    Hi,
    We have a problem which we think is ZFD related. Immediately after the
    login there is a black screen presented and the pc appears to be doing
    nothing. After 30 seconds or up to 3 minutes the desktop appears. At
    that moment the NAL starts and again we have to wait for 1 to 5 minutes
    for the NAL to appear.
    Here are some figures:
    3300 users
    700 applications
    7 cluster servers
    NetWare 6.5 sp5 + nw65sp5upd1 + iscsi65sp5a
    GroupWise 7.0 sp1
    ZenWorks for Desktops 7.0 sp1
    (and iPrint, BorderManager 3.8, NetMail 3.5.2, Identity Manager 3.01)
    Windows XP sp2 fully patched
    Office 2003
    Novell Client 4.91 sp2 + pkc
    We are using DLU. The difference in the delay times is because of
    hardware. On older hardware you'll have to wait longer. That makes sense
    but keep in mind the oldest hardware is still a P4 1,6 with 256Mb RAM.
    But 1 and a half minute extra startup time for a brand new pc is still
    quite a lot.
    We have had an expert at our site. The obvious like SLP, DNS was not our
    problem. He took some traces and again no problems found. There are some
    posts with ZFD 6.5 which mentions this black screen but no solution is
    provided.
    Most of our applications are associated with the users' container.
    Anyone please?
    Joost Sannen

    Hi Craig,
    We'll follow up your advice and let you know. Currently I'm at home with
    the flew so you have to wait for it.
    Thanks,

  • Torch 9810 slow red flashing light then black screen

    Hi,
    My phone is over 1 year old, so its not covered by Wind provider warranty. its 15 months now. One day, I plugged into the computer, it was doing an OS update, then froze at 30%. ever since, it is flashing red a few times then nothing... complete black screen. I tried it on different computers and even went to retail store and they tried it, nothing. They said its a blackberry OS issue and need to restore to factory OS and let it do update again. how do i do this? I know its not battery issue because we tried other good batteries. help!!

    Hi and Welcome to the Community!
    Please refer to this official download portal as you proceed. It is sorted first by carrier -- so if all you want are the OS levels your carrier supports, your search will be quick. However, some carriers are much slower than others to release updates. To truly seek out the most up-to-date OS package for your BB, you must dig through and find all carriers that support your specific model BB, and then compare the OS levels that they support.
    http://us.blackberry.com/support/downloads/download_sites.jsp
    From a PC, you can install any compatible (e.g., for your exact BB Model Number) OS package to a BB via this procedure:
    http://supportforums.blackberry.com/t5/BlackBerry-Device-Software/How-To-Reload-Your-Operating-Syste...
    Note that while written for "reload" and the Storm, it can be used to upgrade, downgrade, or reload any BB device model -- it all depends on the OS package you download and install to your PC. After installing the OS package to your PC, please remeber to delete, on your PC, all copies of VENDOR.XML...there will be at least one, and perhaps 2, and they will be located in or similarly to (it changes based on your Windows version) these folders:
    C:\Program Files (x86)\Common Files\Research In Motion\AppLoader
    C:\Users\(your Windows UserName)\AppData\Roaming\Research In Motion\BlackBerry\Loader XML
    Be sure that you remove, from your PC, any other BB device OS packages as having more than one installed to the PC can cause conflicts with this procedure.
    You may also want to investigate the use of BBSAK (bbsak.org) to perform the wipe it is capable of.
    You may also want to try the "Bare Bones OS Reload Procedure" to attempt to narrow down the precise causal item:
    Load your OS "bare bones"...if anything is optional, do not install it.
    If the behavior presents immediately, then try a different OS with step 1
    If the behavior does not immediately present, then run for as long as it takes for you to be sure that the behavior will not present.
    Add one thing -- no matter how tempting, just one.
    If the behavior does not present immediately, then again run for long enough to be sure it will not have the same problem
    Repeat steps 4 and 5 until all things are loaded or the behavior presents
    When the behavior presents, you know the culprit...the last thing you loaded.
    If the behavior does not re-present, then you know that either step 1 or 2 cured it.
    If the behavior presents no matter what, then you likely have a hardware level issue for which no amount of OS or software can cure.

  • When shutting down shows black screen and grey spinning weel and is slow

    i just bought my macbook air a week ago and at first it shut down real quick but now it takes about 20-30 seconds and shows a black screen with a white/grey spinning weel/circle before it turns off.
    also my safari is running slow and i use barely nothing only safari, spotify, word and agenda.
    thanks for the help
    macbook air 13 inch 1.4ghz i think and 128 GB 2014 i think

    The warranty entitles you to complimentary phone support for the first 90 days of ownership.
    If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

  • MacBook slow wakeup, black screen, Mavericks, took to Genius bar, worked OK for about a week and now the same.

    MacBook slow wakeup, black screen, Mavericks, took to Genius bar, worked OK for about a week and now the same.
    Screen actually seems a very dark navy blue almost black. sometimes can see cursor in white
    Only happens sometimes

    If you can somehow document any processes you've put the MacBook
    through, which can cause it to repeat the symptoms you've seen, be
    sure to write down the sequence of events if your action and resulting
    issues can be make re-occur. Then you'd have a fair chance at some
    one looking deeper to find the real cause of this problem. {If you have
    a digital camera handy, you can take a picture of the screen if it should
    display some curious content other than a black screen, such as that
    seen in a kernel panic or other message. Otherwise, a working Mac
    can take its own screenshot.}
    The computer should be returned to the Apple Store genius bar for
    further evaluation & more in-depth diagnostic tests of long duration.
    Sometimes a test may not run any of the additional software, together
    or separately, that you may be accustomed to using. Perhaps the basic
    OS X and a few applications work just fine.
    If the issue is due to a conflict in software and not a hardware failure,
    the cause may be harder to discover. If you have a complete backup
    of the system and your files on an external drive, that may help if you
    need to reinstall it. However if there is a problem in that software set
    a new installation without conflicting software may be required in order
    to troubleshoot the machine.
    How old is the computer, how much RAM installed, how large a hard
    disk drive and what is the remaining unused capacity of that drive?
    (The HDD capacity will show 'other' so that may be unsubstantiated.)
    Are there any indications in Activity Monitor, or in the system log files
    from Console, to show crash logs or other effects from the Time/Date
    of these slow wakeup and black-screen intervals? There may be.
    Some of the system report may be helpful to those who know how to
    read the resulting mass of files. Perhaps one of the more advanced
    users who occasionally reply here will see your thread and offer a
    method of accessing the OS X via Terminal or single user mode,
    for troubleshooting purposes. Mine is an older OS X with less fuss.
    Good luck & happy computing!

  • Slow loading app on android - black screen

    Ive developed a game with flash builder 4.5 as an actionscript mobile project (not a flex mobile project). The game runs fine on various devices (samsung galaxy/ htc desire etc) but is very slow to load initially. Loading takes up to 18 seconds during which time a black screen is displayed. Obviously this isnt ideal because it looks like the app has crashed.
    So my questions are -
    Is this a normal loading time for a pure action script app?
    Can this be disguised by a loading or splash screen?
    How can i speed up loading or disguise it?
    Ive tried embedding the game swf in an as3 container, the container shows a loading screen but only when all assets are loaded so not much use.
    Thanks in advance

    ive since made a few observations....
    1) Install app onto mobile using adb install myapp.apk . Launching initially on android the app takes 18 seconds ish to load. App plays fine. Now kill/ close the app. Relaunch the app. The app now launches in 2 seconds...
    2) Relaunch the app several times and it loads in 2 seconds each time.
    3) Turn off the mobile device for a few minutes. Switch back on. Launch app, app loads in 2 seconds.
    4) Delete/ remove app from mobile device. Reinstall using adb install myapp.apk. Launching takes 18 seconds. Kill the app. Relaunching takes 2 seconds...
    Like i say, no answers here but just a few observations...all i can assume from this is that as3 apps are very slow to run on initially, typically 18 seconds, but run fine ever after....??
    Why is the app so slow to launch initially? If anyone has any thoughts on any of the above id be very interested to hear them.
    Thanks in advance

  • OK. I have connected Apple TV and chosen HDM1 input. Now what do I do? I am only getting a black screen with HDM1 and "player 1 (BD System) at the top of the TV screen. Help!

    I have given my hiusband Apple TV for Christmas. We have just connected it and are just seeing a black screen with HDM1 &  Player1(BD SYSTEM) at the top of the screen. Next step is to go onto Settings but I can't seem to get this to work. The screen won't respond to the Apple TV remote. I did pair it to the TV by pressing menu and Right for 6 seconds but nothing happening.

  • TS1702 The default Camera application is not responding, it comes with black screen. Functions on the screen are unresponsive, very slow.

    Dear community,
    The default camera application became un-usable in my iPhone5. Cannot operate camera at all. It comes with a blank/black screen, camera controls are unresponsive, front-back camera toggle switch takes couple of minutes to response but with a blank/black screen both front and back.
    I searched solutions and applied but none seems to work. I reset my phone, started as blank, with no user account, still camera is acting same (or rather not acting). Other apps that use camera give error when try to access the camera such as whatsap and skype. Facetime comes with a very blurred view. Couple of screen shots are attached.
    I think need to erase and reload the camera program but I could not find how to do it. Is it possible? or is there any other suggestions?

    Hello hakanid,
    The following article provides some useful troubleshooting steps that can help get your iPhone's camera working.
    Camera isn't functioning or has undesired image quality
    If the screen shows a closed lens or black image, force quit the Camera app.
    If you do not see the Camera app on the Home screen, try searching for it in Spotlight. If the camera does not show up in the search, check to make sure that Restrictions are not turned on by tappingSettings > General > Restrictions.
    Ensure the camera lens is clean and free from any obstructions. Use a microfiber polishing cloth to clean the lens.
    Cases can interfere with the camera and the flash. Try gently cleaning the lens with a clean dry cloth or removing the case if you see image or color-quality issues with photos.
    Try turning iPhone off and then back on.
    Tap to focus the camera on the subject. The image may pulse or briefly go in and out of focus as it adjusts.
    Try to remain steady while focusing:
    Still images: Remain steady while taking the picture. If you move too far in any direction, the camera automatically refocuses to the center.
    Note: If you take a picture with iPhone turned sideways, it is automatically saved in landscape orientation.
    Video: Adjust focus before you begin recording. You can also tap to readjust focus while recording. Exiting the Camera application while recording will stop recording and will save the video to the Camera Roll.
    Note: Video-recording features are not available on original iPhone or iPhone 3G.
    If your iPhone has a front and rear camera, try switching between them to verify if the issue persists on both.
    My issue is still not resolved. What do I do next?
    Contact Apple Support.

  • OS 10.4.5 failure to startup-login window/ black screen/ blue screen-frozen

    Hi there,
    To anybody that can help me, I thank you very much indeed in advance.
    G4 Powerbook, 1.5gHz, 2gb Ram (1gb kingston ram added since purchase date), OS 10.4.5, security update 2006-002 (v1.1 (?) recently installed).
    My current problem is that i cannot log into OS X. It boots as far as the login window, which is unresponsive, and then it then flicks to a black screen with 2 or 3 lines of white text and then flicks to a totally 'mac-blue' screen with the black arrow pointer still active.
    A history of my problem;
    1) Yes, unfortunately I tried to get front row to work on my machine (the hack with the front row enabler etc), and subsequently removed all traces of it after it screwed up a few things (menu bar missing, failure to restart). This tidy-up involved doing something with system library, bezel services...etc.
    2) I recently installed the first version of security update 2006-002. i am not saying this is the cause, but sometime after I did this, things started going wrong again. another thing i did recently which i hadnt in the past was to have itunes appear at startup and a few days later i emptied my hard drive of all my music and had this linked to a lacie 250gb via firewire 800. The problem at this was that login/startup was incredibly slow and sometimes the finder would keep relaunching itself on its own once the operating system was up and running. Also, when i tried safe boot, the login window would appear and then it would flick to a black screen. it would let me type in a username, but it would not let me input anything for the password.(I did use disk utility to repair permissions when i did manage to logon).
    This whole problem seemed to go away for a day or two, but the login was still slower than usual the past few days.
    I then turned on my powerbook this morning and login was extremely long and never completed fully- lots of pinwheel spins, menu bar not loading, itunes not appearing.
    After a few forced shutdowns I left the computer for maybe 5-10 mins and it seemed to sort itself out after a few finder relaunches etc, and so i tried a few things;
    3) I tried installing the newer version of the security update 2006-002 version 1.1 i think? At the same time i took itunes off the startup launches and also switched off auto login for my account (a silly idea it seems).
    Since restarting from the security update, the operating system gets to the login window, which is unresponsive, and then it then flicks to a black screen with 2 or 3 lines of white text and then flicks to a totally 'mac-blue' screen with the black arrow pointer still active.(this is with the power adaptor connected only, no other cables etc)
    I have tried Resetting PRAM, and using fsck, although I am slightly unsure as to whether or not this is useful to me anyway. I cannot reinstall the operating system until next week as my mum has my copy of tiger at home a few hundred miles away!
    Any help at all would be so greatly appreciated, especially on the eve of my two year anniversary with my powerbook!
    Kind regards,
    Henry Harker

    Hi Henry
    I've just encountered this problem with one of our computers at work. Hopefully this will help.
    It's a Login Window Prefs problem. It's probably corrupted so you need to remove the prefs file.
    1. Startup in safe mode (hold down shift). You should get a login window for the master admin account.
    2. Delete the file: userName>Library>Preferences>com.apple.loginwindow.plist
    3. Restart.
    Let me know how you go.
    Cheers

  • Black screen on startup - Radeon graphics driver or EDID issue?

    Having installed Arch, I am only able to boot into Linux (console mode) when I pass the option "nomodeset" in GRUB to disable KMS. If I try to boot with KMS enabled then the screen goes black almost immediately upon boot. There appears to be no further activity from the system: I can't even reboot using CTRL-ALT-DEL. Nor is there any log activity that I can find. The system appears to just hang.
    My graphics card is a Radeon 9200. From a general websearch, other people have reported a similar issue with this card on other distros, but the "solution" they get is usually "it now works with the updated version of $(DISTRO)". My next move should probably be to try the Catalyst driver, but there's one other thing that suggests to me that the problem is more to do with the monitor (specifically, with the EDID provision) than the driver....
    Running "vbeinfo" at the GRUB command line shows the default resolution as 1280x1024x32. When I run "vbetest" at the GRUB command line, I initially get the graphics test pattern displayed correctly. However, when I press enter to end that test pattern I don't return to the GRUB command line. Instead I get a black screen with a blinking white cursor. No input from the keyboard is displayed if I type, but pressing CTRL-ALT-DEL to reboot does work from here.
    I've looked at the section on the Wiki about Forcing Modes and EDID, but this area's still very much a mystery to me, and the Wiki itself says that this secition is still "a WIP". I guess I'm just wondering if, from the behaviour above, if the problem with using KMS is due to an issue with the graphics card itself or if I should be trying to generate my own custom EDID file, which sounds painful . Passing the built-in resolution 1280x1024 via the drm_kms_helper.edid_firmware option, as suggested on the Wiki, made no difference in behaviour at all. Trying to pass 1024x768 in the same way did make snowy artefacts appear on the monitor, but didn't get me to a point where the system appeared any closer to actually booting up.
    Any advice would be appreciated. I've currently got the X running fine using the VESA driver (no custom Xorg.conf file needed), but it's more than a little slow. I'd like to have 2D acceleration available at the very least.

    Unfortunately it's a desktop with a flat-screen monitor; VGA cable connection. The only information on model that I have is from the monitors' configuration menu:  "Dell E248WFP".

    So I need some help regarding my Mac and it's driving me mad! Its a bit tempermental and it isnt always the same occurance each time, but basically symptons are (somtimes it occurs, sometimes not with each one!):
    Turning on It will freeze on white screen (no logo)
    upon waking up from sleep it will display black screen with mouse and notifications. no login UI or wallpaper. Can SOMETIMES login if i just type password (as if login screen is still there). mouse dissapears once typing begins
    Sometimes when the previous event occurs (^) and i put computer to sleep it will then do the opposite and display just the wallpaper with no input from mouse, keyboard
    I have tried removing all devices (webcam, USB mouse etc) and turning on computer but as its tempermental
    I have also reinstalled a new OS X over the top from internet recovery
    Also reformated HDD and restored OS X.
    Also reset SMC and NVRAM.

    Also run the AHT extended test, no issues detected.
    Also set "sudo pmset autopoweroff 0" and "sudo pmset standby 0" in Kernal.
    Also repaired disk permissions, it only repaired the printer stuff.
    After i gave this in kernal, i then reset SMC again to check.
    Checked console and noticed a 40 second gap before this error:   "05/02/2014 07:03:00.266 configd[55]: inet_set_autoaddr(en1, 1) failed, Resource busy"
    turned off my WiFi and issues still persisted.
    This had previously been on forums last week in Mac Mini section with the help of 'BDAqua' however im out of options and need some more help. If anyone could be helpful enough to give some suggestions on why my screen is black upon waking up (exc. notifications. they appear) and most time i need to hard reboot (sometimes i can type in password and it unlocks).
    I can not afford to start fresh, i have a 110GB iTunes Library with 210 iOS apps and photos too important to me to be forgotten.
    PLEASE HELP ME

    Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.
    Isolating an issue by using another user account
    If the problem is still there, try booting into the Safe Mode using your normal account.  Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don't do them all at once.

  • Black screen on wake up - subsequent unwanted reboot

    I have troubles to wake up my MacBook Pro. If it has been asleep and asked to wake up (by hitting a button or moving the mouse) it gives me a completely black screen (in 20% on the times). I am not an expert in power saving techniques so maybe 'sleeping' is the wrong expression. What I mean is the-state-where-the-screen-goes-black-after-a-few-minutes.
    In this 'black' mode the mouse pointer can be seen and I can move it around. After that, nothing happens. If everything was in order, I would get (in the other 80% of times) the login window for my password.
    By pressing <return> (the only key that triggers anything at all) the computer reboots without any further questions. I am then welcomed by the initial log in window - all work and unsaved documents gone ...
    The problem seem to occure more often when the machine is working hard in the background. The programs I run are not exhausting the memory by far and I have run the hardware checking tool (boot with 'D') and the disk utility (boot with 'C').
    Could this be a Intel specific problem ? On my PowerBook running the same OS version I have never seen this. By the way, my (subjectiv) impression is that the responses of Mac OS to 'user input' like wake-up is much slower on the new Intel machine than on my old G4 ...
    I am using the machine to do long running calculations and this problem renders the Mac almost useless for my work, since I can not sit there and press a button every two or three minutes to avoid 'sleeping' (and setting the machine to never sleep is not really an option, is it ?). I would like to use the new machine (Dual Core Intel) exactly as my old G4 one ...
    Any suggestion would be helpful. Thanks, and appologies if this question has already been answered.

    Hi! I was hoping you would get some good answers to this because my system does the same thing. I do have one answer for you. I downloaded a program called Caffeine which allows you to stop the sleep mode. when you open the program it puts 3 zz's on your top panel and you can click it to keep you PC from sleeping. Good luck! I will be watching for responses. Arias
