Satellite Pro M40 sometimes starts with white screen


I'm pulling out my hair with this problem.

For no definable reason that according to me, my laptop will start with a blank screen.
Not all the time, but, seemlingly, whenever it feels like I need extra help stress on my plate.
For the most part, with perseverance (starting with or without battery, with or without the adapter, with or without pci with or without mouse usb network card and any combination of these elements), it ends by lights correctly, but sometimes Nothing that I won't get it to start and show me a screen.

My M40 is 4 months old.
Since it's purchase sent to Toshiba for repair twice for this problem, when I have exhausted myself trying to coax it into life. Whenever he was sent by saying either the problem has been fixed, or that he had no problem found/all systems ok / "it works very well for us, after testing all week."

This week [edit: it was Wednesday], I sent it to me, and Yes, I checked the trunk upwards and gave a sigh of relief that there is an image on the screen.
I wrote a letter to this topic a day or two later (that day he first gave me a screen white, but on closing down and restart, it was fine).
Today, however, not a week later, I have a white screen again.

I am reluctant to send for repair again, due to the stress involved and the time it takes and the technicians speaking it works for them.

If anyone can help, or was faced with a similar problem, please respond.

Oh, and the solution does not lie with the keys FN + F5, because I tried several times... unless there is a way to 'special' to build on them, I'm not in the running for!

[Edit]: several hours later, as a demonstration of her bored this problem is, my screen is once more working.

I went on once again, at the time and no joy. Then, after switching OFF, count to ten and the restart, eureka.

I'll update with news as it happens. If there are all the necessary specific details about "switching on the environment", just let me know.

It's a very strange question, and it would be very helpful if you can put yourself more observational.

  • Satellite Pro C70-A-159 boots white screen (or almost)

    A non-technical friend asked me to look at his Satellite Toshiba Pro C70-A-159.

    It was a Christmas gift and worked perfectly for eight months two days ago (according to him), he won t boot. Actually, it does, in a screen with no connection options to stop / restart / activate on screen keyboard etc. (reading these forums, is not an uncommon problem).

    I suspect it has improved to 8.1 from the Microsoft site, no Toshiba. Before making a full backup of the data, regress of Windows 8 and follow the (fairly complex) instructions for upgrading to 8.1 properly, is there anything else I can try?

    Hi Adrian

    I also think that you should test the functionality with the factory settings. Talk with your friend and ask if there is some important data saved on his computer. Make a backup and install original recovery image.

    Here's the brief description -
    What you can do too before start you is to create recovery media, just to be sure you if something goes wrong. You can create this preinstalled use Toshiba recovery media creator support.

    Reinstall the original recovery image and check a bit how it works. You can improve it later to Win8.1.
    Here is page s Toshiba on the steps how to do this -

    I think that your friend will be happy when you do all that and bring him back 100% of work and Win8.1 machine.

    Good luck

  • Satellite Pro A200SE-1F9 starts showing blue screen


    I recently bought a Satellite Pro A200SE 1F9 (2.00 Ghz, 2 GB RAM, professional running Vista), after 4 months he began to launch Blue error screen. I tried not to upgrade or fix a new material. I had a Linux Fedora 7 (dual boot), as I was getting this error quite often I got Vista Business (using Toshiba recovery disc). Now, I have only Vista in my laptop (lost Linux completely).
    Some time the Notepad starts and goes inside Vista, after 10/20 mts, it starts again after showing blue screen, in other cases it keeps restart after a quick blue screen start.

    I'm really frustrated by this behavior and don't know what to do. Can someone help me please in the present.

    Thank you

    Have you installed a few applications which can be responsible for that?

    I can't imagine that the BSOD occurs after a clean install of Vista OS.

  • start with white screen and a page named do not work

    Firefox always start with most recent screen.

    You can check if you have a user.js file in the Firefox profile folder that affects the pref browser.sessionstore.resume_session_once true value.

    You can use this button to go to the Firefox profile folder currently in use:

    The user.js file will be present if you or a other software created this file and normally will not present.

    You can check its contents with a text editor (right click: 'Open with'; do not double-click).
    The user.js file is read whenever Firefox is started and initializes the preferences to the specified value in this file, so the preferences set via user.js can be changed temporarily for the current session.

    You can remove the user.js file if you do not create this file yourself.

    Do not change the line browser.sessionstore.resume_session_once and change its value to false, but either delete this line or remove the user.js file (recommended if you have not created this file).
    The normal use of this pref is to reload the tabs when you need to restart Firefox (update or install an extension).

  • Satellite Pro A200 - cannot start with new RAM

    I have two of these laptops, both purchased at the same time.
    I upgraded to 320 GB hard drive and tried to move the RAM to 4 GB as the spec States can be made.

    I used the recommended type of RAM, but the computer does not start with two RAM modules inserted. If I remove one of them, the laptop boots! I thought that I update the BIOS but found the only version available on the download web site is the same as I.

    Does anyone have an idea what could be wrong?

    What RAM you bought? I think that the modules are not compatible or your chipset does not support the 4 GB.
    Check it with CPU - Z!

    You could test the RAM with Memtest86 ([]).

    I doubt that a BIOS update will solve the problem. A more recent BIOS does not change the decision-making ability and/or supported RAM.

When I tried to start the computer, it could not start. the machine was normally closed the last time. with no beep, the screen remains white and black, without any modification. After 2 seconds after you press the powerkey, he was arrested with a short beep. Here is what I tried:

    2, remove the AC and battery system. Press and hold the power button several times (3 - 5 times) for a 5 secondsReconnect AC account and press the power button - if the system boots normally, stop and insert the battery. does not work.

    Moreover, the machine was purchased in Hong Kong and is still under warranty. However, I am currently in Germany and will stay for another 3 months.

    You can try to repair the system.
    Switch on and press F8,
    Now, you will see the advanced boot options:
    Here you can choose the option: last known good configuration

    If this option does not help, restart the device and press F8 again.
    Choose the first option: fix my computer
    Here, you can choose between different options.
    You can enable Win 7 to find the problems and fix automatically or you will use the Toshiba HDD recovery option to restore the entire system.

  • Qosmio F50-125 starts with black screen after a BIOS update


    After instalation if new bios (v 2.0), computer sometimes starts with black screen.
    Even the first page that show press F2 to enter the bios is not displayed.

    You have someone older version of bios?
    So, I might try if it's the fault of it.


    I think that the old BIOS will not help you because the laptop would have known that you try to update the BIOS to the older version, and it would break to the top of the procedure.
    In addition, the older BIOS is not available on the European driver Toshiba page.
    I think just only a Toshiba ASP had an older version of BIOS.

    Anyway, you said that sometimes happens.
    This means that this issue doesn't still persist
    Hmm. in this case, I recommend the default BIOS settings and update the driver display.

  • Satellite Pro M40: screen remains dark until Windows has fully loaded

    Hello to all here.
    I have a problem with my laptop. My laptop is a Satellite Pro M40.

    When I turn on my laptop, I found the backlight won't come... the screen will stay dark until it has fully loaded into Windows. I've checked all my food, and there all fine options. Even if I can get the Bios screen its impossible to read the txt because without backlight. I tried to hold the Fn & F7... joy of Noy.

    Someone at - it ideas?


    Hello Richard

    I didn't see anything like that before and I'm a bit confused why you can't see the BIOS settings, but running the OS. Use of the FN + F7 key combination won't help because this option only works on Windows and not on the level of the BACK.

    If possible try to plug the external monitor and test again. In any case I put t think you can fix it yourself. Try please contact Toshiba authorized partner in your country. Explain the situation and see what they say.

    If you discover that something please let us know. It will be really interesting to know why this happen.

  • Satellite Pro M40: Files on DVD/CD not visible

    If data are burned to DVD or CD (+ R or + RW completed another manufacturer) then inserted in my Satellite Pro M40 PC he can see folder names but he cannot see all the files in the folder. When you click on the files, he says they are empty!

    When the same disks are inserted on other devices (on DVD players connected to a TV), records show the files and files open without problem.

    Sometimes the same disc when inserted in the pc, can be detected as drive is invalid

    Audio and video disks are no problem and open immediately.

    I am at a loss because even if I backed up all my data I can't re - insert the data if I lose it.


    There are different reasons why you CD/DVD drive doesn t manage burned CDs.
    First all CD or DVD is compatible.
    I had a lot of problems with my mediums sometimes burned the disc was able to read, sometimes, it was not possible.

    I changed the burn at a lower speed, and which has slightly improved the situation. I also changed burning software.
    Now I use the Nero burning Rom software. It s really good program.

    But the main reason for these problems is the anomaly of lens laser discs. After a long period of work of the lens cannot calibrate properly and therefore can't handle the media inserted in this case only a replacement drive helps.

  • Satellite Pro M10 cannot start properly - AC LED flashing orange


    I have a weird problem that I can't solve.

    (1) when my Satellite Pro M10 the plugged AC adapter and the battery, the AC led is green and battery led is orange.
    (2) when I try to turn it on, several times it not light and the dissepear of leds for 1 or 2 seconds and my AC led flashes orange. Sometimes it lights up as it should be.
    When this problem occurs, it will take a lot of time before it turns normally. I searched the internet for a solution, but I couldn't find one.

    I already removed the battery and try to turn it on, but it does not solve the problem. Or when I remove the AC adapter and try to start it on the battery itself.

    I also removed the two of them and you press the button power on for 60 seconds. After that, it will sometimes start with mains or battery adapter.

    My bios is updated to the latest version. (I've done this when he started only five minutes ago, but the problem is not resolved). I also believe that when the m10 is enabled and when I close it, it crashes also.

    Do anyone know how to solve the poblem? Thanks in advance.


    These problems are very rare and shouldn't t happen if hardware or software is ok.
    Power LED blinking orange means there could be a hardware malfunction.
    It is a code flashing microphone and a technician can be read.
    This code must be translated into the hexadecimal digit.

    But for ordinary users it s not able to know what it means. In my opinion a power electronic malfunctions and must be verified by an ASP.
