[Solution] Blank screen at bootup after installing updates

For those experiencing this issue, this is down to an Intel graphics update that Windows Update installed. There is a fix to it in the form of a software update which I have explained about in this thread: http://forums.lenovo.com/t5/Lenovo-3000-and-Valuel​ine/LENOVO-C-SERIES-ALL-IN-ONE-DESKTOP-PC/m-p/3864​...
It is slightly lengthy but if you follow the instructions line for line it'll be done properly and in no time. I'm not a staff member at Lenovo, I'm actually a customer but I thought I'd create a thread if anyone else comes here having the same issue.
It would be great if a moderator of the Lenovo forum would sticky this thread for reference to customers that come across this problem when they apply updates to their new computer. You may find after only a few days of owning your Lenovo C series computer that you experience this issue.

I ckecked all the cables and they are secured. I also popped out the videocard and put it back in but i still have a blank screen on startup.  I talked with a guy at my local PC Club store and he said that judging by my story it could be a power supply, motherboard or cpu problem.  I swapped out the power supply with a new one and it still has a blank screen when powered on.  I forgot to tell you that im running windows xp pro and a 2.8ghz prescot with HT.  Anyone have any ideas?

    macbook pro won't boot after installing update 10.9.3

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode.
    Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?
    After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

  • A problem is after install update december 10, 2014

    A problem is after install update december 10, 2014  UAC settings says unknown publisher , troubleshooting not working, when I want to change any setting it says unknown publisher , windows defender not starting etc

    Hi
    vijay ,
    Have you tried the solution provided by
    Winword Exonar ? Does it work? Any feedback would be appreciate?
    If this is not the cause, then I would suggest you return to a previous point with system restore. or simply uninstall the updates december 10, 2014 , then check if issue persists, we should first find out whether one update included in is the culprit.

  • Updated my iPhone 5 to ios7, in the App store after installing updates I now have a never ending list of the Apps I've updated.  How do I get rid of the list after they've been updated?  In the previous version I did not have an annoying permanent list.

    Updated my iPhone 5 to ios7, in the App store after installing updates I now have a never ending list of the Apps I've updated.  How do I get rid of the list after they've been updated?  In the previous version I did not have an annoying permanent list.

    iOS 7 allows you to have your apps update automatically. Therefore, the list of what has been updated stays so that you can see what was updated, when and what the release notes say. It has been suggested that they list has a limit, much like Recents. Currently, there is no way for the user to delete the entries manually. Just try not to look at them.

    After having shut down after installing updates, when I restarted and tried to open a word doc, it started opening ALL the word docs and the only way I could stop it was by"force quit"  . This is REALLY annoying!!

    May be it is the Resume feature.
    System Preference > General > Number of recent items
    Uncheck the box next to      "Restore windows when quitting and re-opening apps".
    Best.

  • After installing update IOS I've lost my Quicken data, help?

    What Mac do you have?  What version of Quicken do you have?
    Are you updating Quicken or OS X?  What are the details of that update (prior version number and updated version number).
    Also, since this is your first post to this forum, be sure to understand that the first reply is not necessarily the last word on the subject (nor even the first word, as in this case)!

  • ITunes crashes on iPhone after installing update 3.01

    After installing update 3.01, iTunes won't work properly. iTunes starts up, plays a number but crashes after a while. My guess is, that this happens while the iPhone performs other tasks simultaneously (like retrieving e-mail and such). Are there other people with the same experience?

    Update: looks to be a memory-problem (?). When I start iTunes and choose to play the firts album/number directly (without using coverflow), it works fine. For a while at least, until my mail is checked again: iTunes crashes again.

  • Automatic double reboot after installing update

    Hello everyone,
    After installing update 10.5.6, my computer automatically restarted twice (the double "bong" sound). I was wondering if this is an unusual occurrence or part of the normal system update sequence.
    Have not had this occur previously and was wondering if anyone else had this effect when installing 10.5.6
    Thanks.
    joe

    My iMac and my wife's MacBook both did the double reboot. It scared me the first time my iMac did the double reboot on 10.5.5 but this time I expected it. On my wife's MacBook it also had a firmware update and for the first time since we bought her computer I heard the fan going at a really high speed for a couple seconds and then stop. The fan has never since come on that fast so I guess it was the computer was just testing the fan.

  • Blank discs not recognized after installing security update

    Just installed the latest security update and now the computer will not recognize either blank CDs or DVDs. The first time I popped one into my external burner, I got the notice that I'd inserted a blank DVD and was asked if I'd like to open it in the finder (even though I had already set this as the default option). Then when I said yes, I got an error message that the disk could not be read. Ever since, I no longer get the notice, just the error message. Moreover, "drutil eject tray" will not eject the disk.
    Same thing happens with the internal drive. Again, drutil did not work and I had to restart to eject the disk.
    Disk Utility shows the disk but will not allow me to format it.
    These disks were working fine until I installed the security update.
    Anybody have any ideas?
    Thanks.

    Could be many things, we should start with this...
    "Try Disk Utility
    1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
    *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
    3. Click the First Aid tab.
    4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
    5. Select your Mac OS X volume.
    6. Click Repair. Disk Utility checks and repairs the disk."
    http://docs.info.apple.com/article.html?artnum=106214
    Then Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
    The usual reason why updates fail or mess things up, is if Permissions are not fixed before & after every update, with a reboot... you may get a partial update when the installer finds it doesn't have Permissions to change one obscure little part of the OS, leaving you with a mix of OS versions.
    Some people get away without Repairing Permissions for years, some for only days.
    If Permissions are wrong before applying an update, you could get mixed OS versions, if Directory is the slightest messed up, who knows!
    If many Permission are repaired, or any Directory errors are found, you may need to re-apply some the latest/biggest updates.
    May even need to do an Archive and Install if you have room on the HD...

    I only use Software Update to see what is needed, then get them for real via...

  • Blank screen & no booting after running BIOS update on Satellite A200-1AE

    Here is my problem with my A200-1AE (PSAECE) Notebook:
    I downloaded the latest BIOS update from the Toshiba download drivers library to install Win XP since finally the drivers are realized. (Note the update clearly stated to run ONLY if you want to install XP on you NB).
    So I unzipped the file and after hitting the .exe file it started updating the BIOS on its own without me giving the liberty to do so. Half way the N/B froze for about 20 minutes and as I didnt know what else to do so I reset it.
    Result? The NB does NOT boot. I press the power button, the Hard Drive icon flashes 2-3 times as well as the DVD drive, I get a blank screen and the power cord & power button icons constantly on. I removed the battery and the power cord for 48 hours hoping it will reset the BIOS on its own to no avail.
    The BIOS battery is under the touchpad which means I have to disassemble the whole laptop and I am not ready to do so. I dont know if on the motherboard there are BIOS reset jumpers and I need someones help as to what I should do. I am starting to think that things where MUCH easier back to when I just had a desktop PC.
    THERE must be something I can do other that taking it to the service center and pay half the value of the laptop in repairs.... PLS HELP Im desperate....

    Hi there,
    first of all: a notebook is not a desktop and such mobile computer does not have jumpers like a deskop computer. They surely have something to delete the BIOS but I am not so sure IF resetting the BIOS could help you.
    I guess you will have to send your machine to a service center for repair because in such cases you will have no other option. Do you have still warranty on this machine?
