A80 - 154 does not start - only black screen with strange resolution

Hello!

I have a big problem with the laptop. When I start it the power led and battery LED or power plug LED is blue (depending on what energy source is used, the problem appears both!). It's normal. But you don't see anything on the LCD screen. And nothing happens. Are lit, display is not black, no sound of the HARD drive or the fan. When I connected my external 17 '' TFT, he says that there is a signal, but the screen remained black.

The signal has a resolution of 720 x 400 70 Hz, which is a very exotic resolution and a strange frequency! Anyone has any idea what it could be? I connected no matter what USB or other device. Only the laptop with or without the battery.

Hello

Well, it's not easy to say what may be the problem. I think it s a hardware malfunction, but I don t know which part might have a failure. Maybe it's something wrong with a CPU or memory modules s.
In this case, I recommend to contact the service partner. He can do some tests.

Good bye

  • Re: Satellite A100-011 does not start, a black screen at the beginning

    I have a Toshiba Satellite A100-011, which is almost 5-6 years. It suddenly started to behave abnormal.

    First of all, I started to get a 1-2 sec black screen when he was running. The screen was on and off occasionally.

    After a few days, I could not started upward from my windows xp sp3 operating system. I tried to start in safe mode with networking to see if I had a few spy, virus or something. I ran avast, hijact, ad-aware and some more, but not found anything.

    Later, I tried to format my laptop with a xp professional, but this time I can't see any reflection that passes more fun running and a black screen. I just got a black screen at the beginning and it does not start.

    I plugged on a television screen, and here I have started. I have re-installed all the drivers and formatted, but all I get is a black screen on my laptop at the beginning.

    What should I do now? Do you think I have a problem with my screen of HW or a driver problem with nvidia geforce go 7600? Maybe I'm missing something?

    Thanks in advance for all replies.

    If you can see the picture on the TV there are a few s laptop display problem. Y at - it some problem connection or display itself.

    You want to fix it yourself? You can disassemble the laptop?
    I mean if you have any experience with this kind of things that you should seek professional help.

  • Vista does not load a black screen with arrow

    Windows Vista will load only a black screen with the white mouse arrow.  I can move the arrow but by pressing the keys (including ctrl-alt-del and ctrl-shift-esc) does nothing.  The only way to turn off here is to press and hold the power button.  Same thing in safe mode.

    I tried the "Repair your computer" option (F8, or from the Windows DVD).  The Startup Repair option says that he finds no problem.  There is no restore point on the computer if it is not an option (it isn't my computer, the person who owns it is said that there should be a restore point, but if there is, the computer can't find it).

    The Dell (F12--> Diagnostics) system diagnostics found no problem (I'm sure this isn't a hardware problem).

    I tried to do a "repair installation" as in Windows XP, but this isn't an option in Vista.  The closest thing is an upgrade installation (boot from the Windows DVD, select install, upgrade).  But this option is grayed out, and he said to level I have to start the installation of Windows.  But of course Windows won't load.  Very smart Microsoft...

    The only option left is to do a clean install.  All programs and files are saved if we have all the data.  It will be just to save a lot of time and hassle if I can avoid it, and I'm surprised that such a feature/option useful XP has disappeared from Vista.

    Any ideas how I can fix this without having to do a clean install?  Thank you!

    Hello biznatch.

    Thanks for posting on the Microsoft answers Community Forum.

    Unfortunately, after trying a startup repair and hovaing, restore points is no longer to go to resettlement is all that remains to be done.  Excuse me, but this is what must be done.  It is excellent that you have already backed up your important information.

    Thank you

  • Dv6 6155TX: laptop does not start. Black screen. LED, work of fan key, function

    Hi, my laptop is not starting, not even the BIOS or the manufacturer logo. I checked the RAM, tried to reset the CMOS battery, removed the HARD drive. At first, it worked for 2 - 3 times, but after 5-6 hours when I turned it on, it does not. I don't think that this is a display problem because windows key + B produces no beep. CPU fan works fine. Help, please.

    Hi, the problem was the corruption of the BIOS because of power failure. I have reset the BIOS of the USB.

    Thanks for you answers.

  • Vista will not start! Black screen, no mouse, no cursor pointer. Startup Repair cannot repair. Details say 'wrong pass '. What is the correct syntax for pkgmgr to uninstall?

    Vista will not start!  Black screen, no mouse, no cursor pointer.  Startup Repair cannot repair.  Details say 'wrong pass '.  It looks like all the files are well intact on the disk.

    What is the correct for pkgmgr syntax when you try to uninstall an update by using a command prompt when starting Vista OS disk?  I entered the following in the "x:\Sources >" prompt:

    start /w pkgmgr/o: "C:\; /Up:Package_1_for_KB2840149~31bf3856ad364e35~x86~~6.0.1.0 C:\Windows.

    When I run this command it ends quickly and when I run 'echo %errorlevel%' I get '5', which seems to mean 'access denied'.  How am I supposed to have access to remove the patch?  Am I missing something?  Perhaps a switch in the syntax to access?  Help, please.  Thank you.

    I tried both options that you recommended.  As initially stated, no boot option would produce something other than the black screen.  I tried to boot from a drive and restoring the system running, but she didn't, and when I tried to do it again the recovery console could not find restore points. ?.

    An update, the computer is now fixed.  Oddly enough, I ran recovery of starting a drive at least 8 times and each time I checked the details and he said: he ran chkdsk without error and return to the same cause "a patch is preventing windows to start.  I even ran chkdsk c: /f from a prompt command from the recovery disk and it found no errors.  That's when I posted the question above after trying to remove the patch in the manner described above.  After some time and frustration, I decided to run chkdsk /r c:.  It took awhile, but it found 1 bad sector, moved the data, the bad sector tag and finished.  Once I restarted from that, everything came and went very well.

    So, the original question remains, what was missing in the command to run pkgmgr/high: successfully.  And the new question exists as to why start Recovery claims run chkdsk if it does not, or he turns the version/f not the version/r the same as I did manually?  It would be good to know for the future.  Thank you!

  • Satellite Pro L300-21F does not start and the screen remains blank

    L300-21F is aged 18 months, so out of warranty. When you press the power button, you can hear the fan and a "click" but the hard drive does not start and the screen remains blank. The power and the battery on the headlight LEDs, but the switch light does not work. I checked the power supply and it is 19.3V and substituted a good known. Removed the battery, tried with just the power cord and still nothing. Pressing ESC or F2 when you press the button power does not bring to the top of the screen of the bios or any other message. I have concluded there is no power the jury. A friend he had its technology take a look and he concluded Council is probably a friend.

    So my questions are:
    1. He's probably right?
    2. is it a common problem with an easy solution?
    3. what else can do before shelling out for a new Board of Directors?
    4. is there a link where I can find how to disassemble the case?

    Any help appreciated

    Hello

    > 1. He's probably right?

    Yes, it looks like motherboard failure

    > 2. Is this a common problem with an easy solution?

    If it's a motherboard problem, the whole motherboard is replaced. Quite expensive part...

    > 3. What else can do before shelling out for a new Board of Directors?

    I don't think you can do anything with fried mobo

    > 4. Is there a link where I can find how to disassemble the case?

    I would like to point out something that you may not realize: Windows 8
    has two interfaces; the modern/Metro Interface (which may be all the)
    you have looked at) and the traditional desktop Interface. You can use
    one or both. This traditional desktop Interface is almost
    identical to the interface of Windows 7. the biggest difference is that
    There is no Orb start clicking to bring up the start menu.

    But note that you can get the ORB start by using one of the many
    third-party programs, are free or very cheap (the classic interface
    http://classicshell.sourceforge.NET/ and debut8 to
    http://www.stardock.com/products/start8/; my personal preference is
    Debut8, but they are both very good).  And goes from an interface to
    the other is very easy; There are several ways, but simply by pressing
    the Windows key is perhaps the easiest.

    Just install one of these two and using the traditional desktop computer
    interface may be a better choice for you than going to Windows 7.
    I use Windows 8, almost exclusively with traditional workstations
    the interface and with 8 Start installed. If you were to look at and use
    my computer, you may have a hard time realizing that it is not
    Windows 7.
    I also recommend to read "how to make Windows 8 or 8.1 watch and.
    Want Windows 7 "to http://www.howtogeek.com/elk/298/45121/4206
    I can't address the issue with your games, except to say that
    whenever you move to a new version of the operating system, some of
    which is used to run on the former does not work on the new. And it's
    much more likely with utilities and games with companies

    Hello!

    It sounds like a hardware malfunction...
    If you have installed two RAM sticks try it with a single. Check it!

Next time, it took 20 attempts to initialize and now it does not start, it will be maybe if I try like 100 times he can do... The problem is when the Compaq screen comes up it comes only for like a second so I know that it does not start, if the Compaq screen stays for a few seconds as 3 + I know it will load windows and start.

  • Satellite 2450 does not start - only in safe mode

    Hello

    I'm having a problem with my Satellite 2450 where it is not initialize properly - is stuck in the screen of Windows XP (just continues to scroll through and hangs there).
    I can boot into safe mode.
    Have not had any other problems with it - no errors, do not have installed/uninstalled anything recently.

    Any ideas what could cause this problem?
    Do you think I should use the recovery disk to reinstall the OS? Anything less drastic I can try?

    any advice appreciated,
    Thanks in advance.

    Hello

    Usually, if the laptop does not start correctly in normal mode, but only in SafeMode because some drivers or / and software applications are false or defective.
    In this case, the recovery procedure should solve this problem.
    If you n t have the Toshiba Recovery CD, you can install from the original CD of Microsoft's operating system, and then you can try to install stuff together from Toshiba (driver, tools)
    These software, you will find on the page of the Toshiba driver.

  • Computer does not start after the screen of the bios, Compaq Presario SR1023WM

    Ok. Trying to fix a friend's computer and seem to have met a strange barrier.

    Problem: The computer does not start after the bios screen.

    Details: When you turn on the computer, the compaq logo with intel inside is and has the < F1 Setup > and < F10 System Recovery > options listed as well.  And that's it as far as the computer becomes.  After that the computer just locked up, no work of buttons on the keyboard lights keyboard ect ect.  I tried the puree on the F1 key, as soon as I turn on the computer and I can handle so he can say * entering setup * but it freezes again after this point.  I already tried to eliminate the possible sources of the problem, removed all expansion cards, HDD and Dvd Rom module only disconnected, only memory (256 MB ddr 2700), power, vga and keyboard connected.  Ive also used the jumper on the motherboard to clear the cmos, hoping that would solve the problem without success.  I tried using a different memory stick and different memory as well...  Tried to use both a ps2 and a usb keyboard... Ive even tried pulling the rider for the protection of the bios password (even if she did not have a password on it, just try everything I can think of).

    The installed bios version is 3.1, and that's all that I know on the computer at this point, except that the website tells me to him.

    http://h10025.www1.HP.com/ewfrf/wc/product?product=411354 & LC = on & CC = US & DLC = in & Submit.y = 5 & Submit.x = 3 & lang = to & CC = US <-link to the Web page for the model #.

    I'm basically at a loss on this one, so if someone feels scroll line-by-line of their brains on this one, I'd be very happy.

    I have a pretty strong understanding of computer repair, so feel free to give me something to try.

    If you need more information out of me, let me know as well.

    Try to clear the CMOS again but this time remove CMOS battery and hold the power button on a few seconds. Replace the battery, then try to start back to the top.

    At the back of the pc is the condition of the PSU led green or flashing?

  • Re: Satellite A300D-13 has: problems starting - starts not or only black screen

    Hello, I have a Satellite A300D-13 has and the problem is, when I try to start the laptop for most, he tries to boot from the hard drive or the DVD drive but then he just stops and starts again immediately to do the same. In this case 4 or 5 times. Once it seems that it starts well, but the only thing I see is a black screen. And the keyboard does not work either.

    If I try several time with closing by pressing the power button (you know who I mean), I managed it starts normally (but such a situation is always annoying). Moreover, it seems that this happens only when I did use the laptop for a while. So maybe it has something to do with the temperature. But more or less 20 ° C in my room.

    In the Bios I have change the boot order of the sources (I can't change it much more)

    I am grateful for any kind of help.

    Hello

    The issue could be related to software, but also for the hardware problem.
    But first, we have to check if it s a software problem.

    You are using the original operating system preinstalled by Toshiba. Is this good?
    AFAIK the most recent series of laptop is equipped with HARD drive recovery option.
    In this case, the Toshiba Recovery DVD has not been delivered with the laptop but there is an option to create a.
    HARD drive recovery option can be used to reinstall and update the operating system.
    I would recommend to repair the operating system and reinstall it again by pressing the F8 key. The Advanced Startup menu should appear and then you must choose to repair your computer.

    This option will start the recovery procedure and the BONES to relocate again.
    Please check if a new facility will improve the situation with Notepad.
    In addition, it would be desirable to update the BIOS, if a newer version of the BIOS is available on the European driver Toshibas page.

    If this suggestion won't help you then whole notebooks material must be check by a local ASP.
