I use the Satellite A200-1TJ
Model without 3rd ETA - 03W00HGR
Windows 7, 64-bit

my screen scrolls quickly itself out of control down.
It's very annoying.
Please, can anyone help?

* I already formatted the disk hard & correctly installed a new windows 7, 64 - bit.
* I updated the touchpad driver

I n know not what else to do.
Please, I need help.
Thank you

What screen do you mean exactly? Do you mean a Web browser window? Window of Internet Explorer?

Have you checked if the screen scroll down if the USB mouse is connected or disconnected?
Also check if this problem appears if the touchpad is disabled using Fn + F9 key

Last but not lease these symptoms can be caused by a malfunction of the keyboard.
In this case the keyboard should be checked before replacing.

  • Satellite A200 - screen is very dark

    Hi all:
    I use the Satellite A200-1DY

    My screen is broken
    the screen can see... but very very very dark.

    When I start the toshiba splash screen appears, but this one (in 1 sec) disappears and the screen is dark.

    I tried with another screen and it works.

    What can I do?

    Thank you


    It looks like FL inverter problem.
    The FL Inverter control the backlight of the screen and if this tiny part does not work, the display looks like Misty.
    It seems that the Toshiba technician would need to replace this part.

  • Satellite A200 screen backlight is disabled

    I'm having a problem with my Satellite A200.

    When the screen is opened, the backlight is disabled. You can vaguely see the screen keep it turned on, but it is too small to read.
    When you close it, you can see the screen backlight turns on, it stays on for just less than one second when you re - open the lid, and then turns off again.

    I guess that it has something to switch the lid being faulty.
    Can someone suggest solutions.

    Thank you very much

    This part of the message is very interesting:
    > You can vaguely see the screen keep it turned on, but it is too small to read.

    According to your description, you can see the screen and eventually the office too, but the entire screen is very low as behind a thick fog.
    Could this be just?

    Well, I think that this problem could be linked to the failure of inverter FL.
    The FL inverter is a tiny part hidden behind the frame of the screen and it controls the backlight of the screen s.

    In my opinion, this part should be checked by a technician for laptop.

  • Satellite A200 - screen turns off without reason

    I have a Satellite A200-E530D on Windows Vista Home Premium. For a month, I had something strange happening on my computer, shortly after the start, the screen turns off. without good reason! the only option I have is hard to system boot and everythings... Although a few times after the restart he still went.

    I tried to upgrade to the last poster of drivers (I have an Nvidia Geforce Graphics card 7300 Go with 128 MB of VRAM)

    Another weird thing, Vista SP1 does not install on my machine. tried to uninstall my Anti virus, but that did not help either one.

    Can anyone shed light on my dark screen?


    You have the same problem on an external monitor?
    I m not sure if it s a display problem, mother or software card

    Do you have what display driver installed? You have downloaded the driver from the Web from Toshiba site? decision-making supported Downloads & => Download drivers

    Good bye

  • Satellite A200 - Touchpad scroll function stop working after BIOS update


    After that I updated the BIOS (drawn from the Toshiba site), the scroll function stop working. I can still click, move the mouse pointer, but can no longer navigate the touchpad. Relocation of Synaptics driver is not the problem. The strange thing is that the computer detects only my touchpad as standard pointing device (port: PS/2) device. "Graph of pressure" and "Moodpad" function also stop working and complain "this program requires a Synaptics TouchPad, and the Synaptics Pointing device driver.
    My computer is Satellite A200 PSAE0C-TR605C.

    Anyone know the reason?
    Thank you



    What operating system is installled and which is more interesting: what version of BIOS you have installed? Why I ask? Because there are 2 different BIOS versions, one for Vista (1.80) and one for XP (5.20) which means that when you Flash a BIOS XP on a computer with Vista installed then some functions do not work properly as the FN keys or the touchpad.

    If please check this out and make sure you have the appropriate BIOS installed.

  • Satellite A200 screen remains black when you try to start

    Hi all

    My Toshiba Satellite A200 laptop computer no longer works, then everything started when I was playing a game, all of a sudden the screen turned blue with a tiny text written on it. I had to hold the power button for a few seconds to close, because nothing not happening on the computer. Then, I pressed the power button to open it. Everything was fine, until the Welcome screen. In this part, he wrote 'Welcome' but Vista left loading circle of it was not turning.

    After a few seconds, I decided to shut down the computer once again, so I hold the power button for the computer firm. Here's the problem: I tried to re-open it, but the screen remained black. Nothing was happening. The power light is blue, but not all computer activity. So I left it like that a few minutes then it closed and tried again, but it's the same thing. I tried to take it apart and noticed the card two memory was not entirely in its niche. I fixed it, but it does not solve the problem.

    I also tried to plug another screen on it, but this one was also black. So I handed the screen on his computer and tried to boot my laptop and it worked. He was the starter, but the first problem came, the Welcome screen was frooze it. So yes I close it up and then it's the same thing, the screen remained black.

    I don't think the problem is the screen, because as I said some time it goes to the Welcome screen. Also, I hear no welcome sound when the screen remains black as if the computer would simply not starts. And as I said earlier, I see no activity of the computer on the little light in front of the computer. And to the left of it, I see clearly that the computer is ON, because the power light is blue.

    That is my problem, the next time that the computer is able to start I'll try to boot mode SAFE, but until then, I don't know what to do. Please, help me.

    Thanks in advance,

    After the computer is turned off for about 30 minutes, I started and booted in safe mode. At this stage, I have locked my computer with the close button instead on the power button. Then I opened my computer and he started and the problem was solved. Now my laptop is open and working.

    So, if this happens to you:
    1. turn off your computer.
    2. wait about 30 minutes.
    3. start in safe mode
    4. close using istead of now off button power button closure.

    It should work.

    Finally, it does not work. I don't know why, but my computer did start after 30 minutes, but now it no longer works. Only, it will not start as I said later, with a black screen.

    The computer worked for about half an hour. I mean, I managed to start but after running a program, it just froze and I had to hold the power button to restart. I made about 3 or 4 times, and then he was simply the black screen again. I think the problem is my processor, maybe that it is damaged or something, would it possible?

    Because I see that the processor does not work when I try start it.

    So let's say that this is the case, would it be the symptoms of my computer?
    And if it's the processor, the only way to resolve this is to send it to a repairman or something, because I don't feel like it, I'd rather do it myself.

    But now, my computer is simply not starting, as I said in my previous post.

    Thanks in advance,


    Note: The Edit button was not there so I had to double post :/

  • After the waiting on my Satellite A200 screen is black

    I would like to ask for help.

    I have problem when I close the lid of my Satellite A200 1 - HV (PSAECE). Computer is going to hold and after I opened the hood, laptop seems to work but display is always black. Only way to make it useful is once again turn the unit off (by the power button) and turn it on.

    Sometimes, the same problem occurs when the computer starts. After loading Windows (XP) the screen goes black and I can't do anything. Sometimes at startup of Windows but the resolution is 640 x 480 and color depth is 16 or even 4 bits!

    I don't know if it's a hardware or driver problem. My graphics card is a GeForce GO 7300. I tried to find one driver other than that on the official website of Toshiba but I can't. This problem is quite annoying. Sometimes I have to try 3 or 4 times until my departure from the computer correctly.

    All attempts to help will be really appreciated.


    Have you updated the BIOS to the version of Windows XP Home edition (5.20)?

    I found a few with similar threads describing the same question. It seems that Windows XP Home edition does not work perfect on laptops designed Vista. Now I'm really curious about it. I install WXP SP2 on my Satellite A200-1CR and test it with Eve profiles different power.

  • Half of the Satellite A200 screen has red pixels


    I plug in a toshiba Satellite A200 1 years.
    Today, I had a problem with pixels.
    Half of my screen has red pixels.
    A lot of black color becomes red.

    I have no idea on this problem and why it's happening.
    What should I do now?

    I would like to get in touch with my dealer? or is there a solution to this issue?

    Thank you


    In my opinion, you should contact the Toshiba ASP.
    Usually after registration for laptop, the guarantee must be valid for 2 years and all part replacements must be covered there warranty.

    My recommendation is; make a call to the ASP and ask for assistance and handling of the Fryer

    Good luck

  • Satellite A200-1J0 becomes very hot

    When I work on my laptop (4-5 hours) long hourks, he is so hot I can't even put my hand on the buttons, and sometimes it's just turns off = ((())
    I don't know what the problem is?

    Some people have the same problem?
    This bad trend started because I installed Windows XP instead of Vista standart.

    Laptot: Toshiba Satellite A200-1J0


    Oh. You have installed Win XP? Well buddy. In this case you must update the BIOS too!
    There is a BIOS designed especially for Win XP, and you should update if you changed your Win XP OS.

    In addition, you should install the Toshiba Power Saver and need to change the settings in the configuration of basic Toshiba Power Saver.
    You will find the option called cooling method. Set it to the Max Performance.

    In addition, you can set the speed of the CPU at a lower level processing and the method of control of the CPU to Auto.

    On the other hand, your laptop can overheat because of the clogged vents and cooling modules. I know this because my laptop temperature was high until I removed the dust from the cooling fans.
    I used a jet of compressed air. You can buy different computer dealers or online shops.

  • Satellite L300 - screen is very dark

    My Satellite L300 screen is so dark, that I can barely see the desktop. So far I have fitted a new screen, a new inverter, you press the power button for ten seconds without the battery and finally re-installed Windows Vista from the toshiba disk without success.

    Can someone tell me where I go from here?

    Have you had this problem too when installing recovery or just after the installation of recovery?

    If you already have Exchange display and the inverter FL, it would be interesting to know if you have the same problem on an external display.

    In General, you can change the brightness of the screen by pressing the FN + F6/F7 key combination.

  • Portege A200 screen goes very dark then works correctly

    Hi, a customer has appealed to a Toshiba A200 protégé (PP415-006002) with lighting LCD problems.

    It happened a few times, first time we thought it was a setting, so we gave him back...
    Second time we disassembled the laptop and found nothing wrong with it, then put it back together, then it worked
    THIRD TIME! : back, ran 3DMARK to stress out the graphics card could not darken.

    Now no matter what I try to do, I can't do the lcd screen to darken, but whenever we give back the laptop to the customer, he always comes back with the same problem
    Can anyone help me that the customer starts to become a little resless.

    If go you into Hibernation mode or suspend, then go back to Windows, the backlight turns back?

    Maybe the inverter needs a cleaning or replacement.

  • Satellite A200 - screen crashes after loading Windows 7

    Intro - programmer by trade, material not my thing.

    Has been running Windows Vista ok.

    I've upgraded to Windows 7 Professional the screen would freeze or have multi color lines on it. Only way out was to turn it off. Tried to do the window updates and update driver without success, it does not solve the problem. I decided to reformat the disk (partition Toshiba always leaving here) and install XP. Had problems to find the drivers and then had problems trying to load them.

    Tried the option "press the button / stop and press 0 (zero)" to try to restore factory default, but it did not work. It shows the Toshiba screen and then something flashes in the lower left corner of the screen and then boots into windows
    So, after careful consideration (and a few beers) I decided it was better to go forward as backward and reinstalled Windows 7. Still have the same problem, but I noticed if I boot in safe mode or safe mode command, the laptop is fine.

    I went to the Toshiba page support download and the have not not all drivers for Windows 7. So I downloaded the vista drivers, but I get an error when I try to install, operationg wrong version for this configuration.

    I can try fix my problem? (Besides that throw the laptop at the door and see how many times it will bounce) :)


    Hey Buddy,

    > Was Windows Vista ok.
    Sounds like this one are a pilot or if preinstalled software problem Vista runs correctly.

    In addition, I think that your laptop isn't Windows 7 supported if you can t get drivers here. You can try the Vista drivers, but if they don't work, to look for the drivers yourself. Maybe another model uses the same material but with Windows 7 supports.

    In my opinion the best choice using Vista if everything is working properly there.

    Maybe this s display malfunction.
    In this case only a part of replacement could help you.

    You can also connect an external monitor to the laptop and could check if it would be noticeable on the 2nd monitor also.
    If the external monitor would be affected, the problem is related to the graphics chip.
