Satellite M40 - monitor doesn't show anything

Hi all

I need help. My laptop is Toshiba Satellite M - 40 model psm40c-jm800e. I don't know what the problem is, but when I turn it on the screen does not display anything. I have the monitor external, but still had the same problem. The new motherboard, I bought on Ebay and it has the same problem. Nothing appears on the screen. Everything seems to work as the LCD is on, fan is running, when I press the function key to switch between an external and internal screen LCD on the keyboard was responding but nothing appears on internal or external monitor. Please let me know what could go wrong with it possible.

Thank you
Alan

Hello

It is s a serious hardware malfunction and that could be another part, as well as the modules of RAM, motherboard, etc.. Should not be the motherboard or LCD internal.

You must contact an authorized professional assistance services provider. They can make an accurate diagnosis of what is wrong and sort this out for you. :)

    System Restore is not supposed to affect personnel

  • Satellite M40 - 114 bluetooth systemboard question

    Hi all

    I have question regardin my bluetooth and the motherboard.

    Center of Service Toshiba has replaced the motherboard in my laptop.
    I can't turn on my bluetooth for the replacement of the motherboard. FN + F8 doesn't work and bluetooth stack reports ' bluetooth device is not ready ". reinstalled XP via orginal Toshiba CD-ROM. But does not help.

    I discovered something strange, is that in the software sis sandra 2005, my laptop is reconignezed by satellite A40 PSA40U. They replace the motherboard with an old model? This could be the reason why the bleutooth no longer works?

    Your help/advice is necessary. Thanks in advance

    Hi phyl

    As much as I know Satellite M40-114 doesn't have Bluetooth and I can't understand this before the replacement of the Board of Directors the Bluetooth system was on board. I know that the M40-193 has a Bluetooth.
    Please check this topic http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=5071. There is an interesting discussion on the M40 and Bluetooth.

  • Presentation of the card: 2nd card doesn't show text in the TextField

    I have a java swing application that implements the map layout and observer template. Basically, in the first map, I key in numbers in the button TextField and click on 'get number', it will run the Calculate class, which returns the number, which then informed his observer who is the Snd class. In the 2nd card (NDS class), it is supposed to set the number passed through the Observable (class Calculate) on the TextField. But my problem is that the textfield on the 2nd map does not appear any text. I already tried the getText method using the print method, and it returns the correct value for the observer last updated. It's just that TextField doesn't show anything. This is executable code.

  • Satellite M40 - shows only 1 GB of RAM instead of 1, 5 GB

    Hello

    I have a Satellite M40-296 with 512 MB of RAM. I bought a 1024 MB of RAM (from Kingston) and put it in the computer. He could show about 1500 MB, but I only have 1024. It s like the work of a few Don t of 512 MB.
    I took out the 512 MB and I 1024Mo, but if I put the 512 MB 1024MB still.

    I updated the BIOS to 1.20

    Can someone help, please?

    Thank you

    Hey Buddy,

    Normally, you can move the laptop to 2 GB RAM max.
    Did you test each module in each slot?

    I put t know that's wrong exactly, but I think that the modules are not compatible together if only the 1 GB module will be recognized.
    Normally for optimal compatibility two modules with the same characteristics and size must be installed.

    I recommend buying a second module of Kingston.

  • Satellite A200 suddenly stops showing anything on display

    Hello
    I have been using Satellite A200 for 2 years and it works very well. Recently, I have problems.
    When I use it all of a sudden it stops to show anything on the display but the power to the front lights are still on.

    This problem occurs often. If the motherboard is fried or there is overheating. I gave my laptop for repairs and they said that they had repaired the system board and cleaned the fan.
    But the problem still occurred. If anyone can help me I will be very grateful.

    If the service cannot help I don't know what kind of help you wait here.
    That's the big difference to discuss on a topic if you have laptops in front of you, or on this way where we can only imagine what the problem may be.

    It's really not easy to say why this happens, but there may be a problem with the display cable.
    This happens to you while you work or after display goes OFF mode (set in the power settings)?

    Hello

    There may be something wrong with the screen of laptop computers.
    I guess that the graphics card is ok because the external screen works properly.

    But it s very interesting to know if you are using the graphics driver from Toshiba. If this isn't the case, please check if this problem also appears after installation of the graphics driver from the Toshiba driver page.

    Hi, I have a laptop Toshiba Equium A300D - 16 c.

    It was fine until now...

    When I press the power button, my laptop turns on but the screen remains black / off.
    The indicator disk HARD is not Flash or anything... (in case that helps)
    I also tried to remove the battery, hold the power button for 30 seconds and then reconnect the power cord... Same laptop turns on but the screen is black.

    I tried to connect my laptop to my PC using a HDMI cable screen, but without success... Laptop turned on but monitor my pc showed nothing.

    I have not changed anything inside my computer laptop or unscrewed it.

    PS:
    Quite often, I kept my laptop on the bed/pillow it may have something to do with overheating or something.

    How did I get to this point:

    Yesterday, my laptop was fine, there was nothing wrong with her... I turned off during the night, but when I tried to turn it on this morning it is where I have faced this problem.

    Any help would be appreciated.

    Thank you very much
    Rejanu.

    Long ago, I had similar problem on my old Satellite. CPU was faulty. After replacing the CPU, everything was OK again.
    I put t really know what to say.
    Maybe you should contact Toshiba and let check your laptop. They have diagnostic tools and may know what is the problem.

    What do you think?

  • Satellite M40-256 - error starting by CD

    Hello

    a well known friend has Satellite M40-256, which Windows problem (error during the update and the manipulation of her children).

    It does not have an external Toshiba FDD or ODD. This laptop is also no built-in floppy drive. Buying one for that matter? NO.
    The boot priority has been changed: CD-network-HDD.

    I tried another Toshiba no ODD (in BIOS not mentioned/found) of brand
    The STRANGE original works/boots in another pc (via an adapter) very large.
    I tried several CD/DVD to boot from (error is displayed): moment-Linux such as knoppix, suse and other windows CD, recovery CD,... without success

    Each time the same result: the laptop has a black screen, the STRANGE is accelerating and after about 3 to 5 seconds, windows starts with the black progress bar.

    I also tried to press C to force startup from the CD.
    Some time previously, I had only access to windows in safe mode. But after uninstalling some updates, it ends with a license problem. This problem can be solved only by starting windows cd via cd.

    It has a bios Toshiba 1.00 (interesting, seems old enough).
    I'm trying at the moment to start the network. The Toshiba shows some messages regarding success/failure at startup via the network or a CD?

    Defined execution bit one influence on behavior?
    Does anyone know a solution to windows startup?

    Thanks in advance

    Check the instructions posted by Akuma.

    If it doesn t work I think that the CD/DVD drive is faulty and must be replaced. Contact the nearest ASP that you can find on the Toshiba site and ask for a replacement.
    It of important that you buy a disc that is compatible with the laptop but the ASP that will.

    Good luck!

  • Satellite M40 startup / shutdown problems!

    For almost 3 months now, my Satellite M40 * don't power up * unless it is completely and absolutely * cold *. It freezes at the beginning.

    Every time I have shut down or restart my laptop, I have to wait about 25 minutes, so I can start it up again. What is happening is stops at the "* Toshiba" logo * screen, from the beginning and he * gel *. I have to press the power button until it turns the power off.

    It's a fact: the laptop is * NOT * extremely hot. Its temperatures are * regular *, I've been monitoring for some time now. If overheating is not the problem here.

    -It also won't stop; it freezes again in the * ' Windows is shutting down * ' display messages... and it freezes.

    -I know that another user of this forum who has had the same problem, but access to its wire has alleged that closed just because some have said of him/her to format and install the OS again. This is * NOT * a software problem! I have tried myself, for all its worth.

    -Today I have updated the * BIOS * also, it has not solved anything.

    So, knowing that I'm not the only one to have this kind of trouble with M40, what to do? Just buy a new one after 2 years?

    Hello Ricardo

    Let's be realistic. It is really possible that software is not the problem but tell me please what you can do in such situation. Not much. In another thread, the guy wrote quite reasonable notice. All you can do is make clean OS install and hope it helps.

    I agree with you that problem described is certainly hardware related issue but you can not do much and portable must be verified by the service. Using specific diagnostic tools, they can say with certainty what can be the problem.

    I don't really understand your last sentence. To be honest on this forum I have seen similar topics but unrelated to the M40 and it's really pointless to understand as untimely M40.

  • Satellite M40-300: is it possible to make a CD or a DVD for all facilities?

    Hello

    I bought a Satellite M40-300, it's a very good laptop
    I just have two questions:
    is it possible to make a CD or DVD for all facilities
    because I have two partitions. One for the window
    and the other for a linux?

    For Linux I want to install Red Hat Fedora Core 4 all devices are compatible or not? and where I can get driver for this?

    Thank you very much

    PS: Sorry for my English I'm French.

    Hello

    First of all there is no drivers for Linux because Toshiba doesn t supports the Linux operating system. All Toshiba units are shipped with the Microsoft Windows operating system.
    I also work with Linux, but I use a different distribution. I use Knoppix because I n t need to install anything whatsoever on the HARD drive and I can use this Linux as other Linux distributions.

    On a CD/DVD creation: do you know that Symantec Ghost?
    This tool allows to create an image file or a CD/DVD image you OS. I don't know if it works with Linux, but as I suggested, you can use a Knoppix ;) m

    Hoppe these tips will help you make a decision.

  • Satellite M40-276 - memory not detected in the Bios upgrade

    Hi people!

    New kid on the block!

    I have a client with a toshiba Satellite m40-276. I've updated his memory to give it a little more to play with...

    Went into the bios to see if everything was OK but no projected additional memory. I removed the new and old memory and put in the new 1 GB module and restart the computer.
    The bios has not yet changed the size of the old memory?

    Went to windows and of course that the memory has been detected it normally?
    I added the other memory module and went into the bios again, but no change it?

    Windows, however, recognized that the two modules?

    His computer is the same bios to factory and has never been updated.

    My questions are... why the bios doesn't recognize the upgrade memory? It will help in upgrading the bios?

    Enjoy all the suggestions I can get on this issue.

    Thank you

    Generally, if you upgrade RAM using tested compatible modules, that should be recognized correctly.
    We do not know what modules you use, and I guess that there is a compatibility issue.

    RAM on Satellite M40 276 can scale up to 2 GB of RAM and compatible modules are:
    DDR2 400/533 256 MB (PA3389U - 1 M 25)
    512 MB DDR2-400/533 (PA3412U - 1 M 51)
    1 GB OF DDR2 400/533 (PA3411U-1M1G)
