Portege M400 sees no more than 3 ~.

I know it is a common problem, but apparently not solveable on my Toshiba M400.

I have upgraded to 4 GB of RAM (2x2gb) and I am running a 64 bit OS, but the OS cannot see that the 4 GB installed ~3.3GB. The BIOS shows 4G. I understand that some machines have a BIOS option to activate the operating system to use all 4 GB. Have I missed something, this feature doesn't seem to be available in the BOXWOOD M400.

What 64 bit OS? If its Vista, try Service Pack 1.

Also update the BIOS with the latest version.

  • Portege M800 - at startup "Please wait" message remains more than a minute.

    Hello

    I'm French and I bought a laptop Toshiba Portege M800-10v!

    Currently, this pc is great! However, I noticed something disturbing.

    In fact: when you start Windows Vista, I get the message "Please wait", which remains for more than a minute! I found that I was not alone! But I can't find any information on it.

    You know more?

    Thank you.
    PS: Excuse me for my English.

    Hello

    If you have any new laptop and if it is connected to the internet for laptop will automatically download new updates and each of them will be installed after restart. If you should not be worried about it.

    Yesterday I installed some stuff on Satellite P300 friends and I waited about 3 minutes after the first and the second restart. It bothers me, but there is nothing to do. To avoid this problem, I changed the update settings and used the check for updates but let me choose whether to download and install them.

  • Portege M400 - cannot use full 4 GB of RAM

    I installed two modules of KTT667D2 / 2G on my laptop (Portege M400-103, part No. PPM40E - 012018 G 3) - total do 4 GB. However, the two original Windows XP Tablet and Ubuntu 9.04 are unable to see all 4 GB - they see 3.2 GB only.
    The BIOS displays the amount properly - 4096 Mb.
    I also tried to solve the problem of updating the BIOS to the latest version (3.80, 30/05/08), but two operating systems (Windows and Ubuntu) see still 3.2 GB only.
    Any ideas? Thank you.

    > However, as well original Windows XP Tablet and Ubuntu 9.04 are unable to see all 4 GB - they see 3.2 GB only.
    That s nothing unusual!
    That s a limitation of 32-bit. All operating systems 32-bit (no matter if it is Vista, XP or Linux) can manage 3.2 GB max.
    Only a 64-bit OS might be able to use and recognize more than 3.2 GB of RAM

    You should read a few articles about 32 bit OS and 4 GB RAM problem.

    See you soon

  • Portege M400: Matter of time life battery

    Hello
    I am looking to buy a tablet PC - was having a look at Portege M400 and model Tecra T7. Although the battery life would be tolerable, I suppose it depends on how you have configured the computer and how to use it - and I'd certainly a margin of safety for more than 5 hours (3 on the tecra). These models have the ability to swap a new battery in and out easily, or install a second battery to increase life expectancy?

    Thank you

  • Portege M400-146 slow startup performance

    My 400 is significantly slow starts, compared to a lower specification laptop that this device was intended to replace. In addition to the understanding of the product, I see that there are more than 90 processes that run on this laptop more almost two times more than my previous unit and a lot more than my Small Business server that runs Win2k3/Exchange/ISA. My question is are there problems by removing the plethora of background tools that are of little use to me, specifically RAID/configfree

    In addition there of the best-known problems associated slow performance/hang up with IE? There is an article that should resolve the issues of States with both software and an upgrade, but he didn't, even the last published this month made no difference.

    In general, this unit is much slower than my previous spec'd base, grateful suggestions

    Hello

    I agree with you. Many processes of background can slow performance of the laptop.
    But it is a simple fact. Each application or function on the laptop needs a clean process.
    Portoge M400 is a portable high-tech and you can not compare with a low price laptops or office that support only a common features.

    The Portege M400 supports the RAID Utility, HDD Protection, Tablet PC button, utility zooming, Rotation, ConfigFree, controls, utility of fingerprints and so on and the rest.

    Of course, you can just disable or remove other feature requests, but then I wonder why you use the Portege M400 with the features and tools together?

    But you can try to upgrade the memory. To my knowledge the Portege M400 supports 4 GB memory max. The upgrade improves performance.

  • Portege M400 - how to remove the condensation of water?

    I received a second hand toshiba portege m400 mail and saw there probably a condensation of water trapped between the external display and touch screen behind her. because the screen in the upper left corner looks whitish. and the sender of the laptop said he wasn't there when he sent it. I have a picture of trapped moisture, for those who want to see it.

    so, I opened the screen by unscrewing. and I saw that most of the moisture is stuck between the external screen glas and one other layer behind him, which I guess, is the part of the touch screen. who looks inaccessible. These 2? the layers form the upperpart of the screen.

    the lcdscreen with all the electronics in this layer, form the lower part of the screen or if you want, cover. This part is now oke. He also had a condensation of water on it and I was able to gently wipe the little moisture of the lcdscreen without problem. This helped a bit with this problem.

    but moisture remains trapped between the part of the touchscreen layer and this layer of glass in the upperpart of the screen/cover.

    hoping to evaporate the moisture, I left the enlightened a bit more open for a day, I broke even the upperpart and the lowerpart of the screen. I applied a little of an infrared lamp, a remote backup heat. anything that did not help.

    * so, how can I remove the condensation of water? *

    * is there a way to remove a layer in the upperpart of the screen to reach the humidity? *

    Hello olekike

    Please don t get me wrong, but I'm afraid, you need professional with this Mr. help as I see that your question is not answered for days now, and I think that nobody here has a lot of experience with this stuff.
    View replacement OK but how to remove the condensation of water on the touchscreen is perhaps too heavy for us.

    I recommend strongly to contact the nearest Toshiba service provider and ask for help. talking with the guys what we can do about it.

  • Portege M400 and Vista - load PSD ends with crash

    I am an owner of a Portege M400 (PPM40E) and recently upgraded my Vista operating system. All new drivers work very well except for the * TPM *. Here's what's happening.

    There's nothing wrong with the installation of security platform. I can create a disc to ensure personal (PSD), load and unload until the first time I got disabling my computer.
    After each attempt to load the PSD is answered by an accident. Two seconds after the sending of password, I get a blue screen that informs me the source of the problem: * PFN_LIST_CORRUPT *, a memory dump file is created and the system restarts.

    Anyone facing this problem? Does anyone know how to restore data from a backup manually the PSD created? The Restore dialog box does not accept the * .fsb file.

    It would be great if someone could help me with this as I have not 'clear' backup files that I had stored on the DSP.

    Thanks in advance,

    Rob

    Hello

    I googled a little and found details of error PFN_LIST_CORRUPT.
    NFP: Page frame number and describes the sharing of individual images of main memory where the driver running or orders of this application.
    If an application or driver is beyond this scope, then a BSOD will appear.

    Here are a few tips and proposals to solve this problem I found on an external Web page:
    -updated the BIOS and set the default settings
    -reinstall and update the display driver, audio driver, LAN driver, etc.
    -Reinstall the security help,
    -update the Windows operating system

    In the worst cases, this problem could be caused by a malfunction of the RAM, and in this case, the RAM modules should be replaced.

    Sorry, but I didn't find more info on this issue.

  • Portege M400 - CPU cooling problem

    Last year, when I had used my Portege M400 for 2 years, he started the deadlock occasionally. Sometimes [I couldn't even start it | http://www.youtube.com/watch?v=RjNa8-c2Aro]. With cut and try the method I found the problem. The Spring wire which clasps the CPU radiator, it was with not enough force:

    The problem was solvable by Berry to the claws spring begins to apply more force hugging the radiator of CPU:

    Apply a new layer of thermal grease has been useful as well:

    However, the solution works for only a few weeks. And then (especially if it's hot outside) the story begins again.

    Any suggestions how to solve the problem once and for all? Thank you.

    Hi Greendrake,

    It s really great that you are interested in your Portege M400 and you can remove it. It of really not easy and so this cannot be the people with a lot of experience.

    Anyway, as you know here our forum user s only. This means that you can speak with normal people like you and me. I would recommend therefore to contact a service provider authorized in your country. Maybe the guys know this problem or something else or you need a thermal grease special because not all compatible thermal greases all cooling.

    By the way: on the Toshiba site you can find a list of all service providers.

    I hope it helps. :)

  • Portege M400: Black screen from time to time

    Hello!

    I have a little problem with my Portege M400 Tablet PC. The laptop runs great most of the time. Unfortunately, from time to time, the screen goes all black - or to be more precise, the screen shows up again. In most cases, the display has been disabled by my energy saving profile, and when I try to put the screen back on (for example by moving the slider or press any key, just like usual), the screen remains black. I see that the computer works and I can for example hibernate the computer, but even after waking up, the screen is always black. Also, it does not help to change the power profile or output or anything - the screen remains like that until I restart the computer.

    I have the new bios 1.80 (because of the better fan control) and I updated the Intel chipset drivers already (I've had the problem before, so it is not the update of drivers). Any idea that he might be, perhaps the bios (it was the first thing I installed after the purchase of the laptop I knew before the fan will be strong otherwise).

    Concerning

    Alex

    Hello Alex

    I found interesting article from Microsoft about this problem. Please check under http://support.microsoft.com/kb/917332/en-us

    Of course, you must install Windows XP KB917332 on your device. This should help.

  • Portege M400: Where to find Windows Vista 64-bit

    Hello!

    I've owned a Portege M400 for a period of 3-4 months now, and I wonder if there is even one person out there who managed to get this laptop computer working under vista 64-bit.

    I finally got bluetooth drivers to work, after the arrival of drivers available. But the following list does not work or I have not found drivers that work.

    -The buttons below the LCD
    -Accelometer (and all the utilities like screen rotation or to do something about tilting machine)
    HARD disk utility - protection (I installed Vista drivers, but they totally destroyed the machine and I had to restore system did not start after the installation of windows)
    -Fingerprint reader

    And I could live if I couldn't get buttons and accelometer to work, but still it would be great that the computer laptop everything would work.

    I'm starting to lose hope and I am already planning to install pirate Vista 32 bit in this laptop... Because it seems that it was a mistake to buy 64-bit ultimate. Some drivers Toshibas indicates they are pilots 'vista', but they do not yet work with the 64-bit version, which has little frustrating...

    In any case if someone could help me I would appreciate it a lot! Because I'm getting slowly frustrated with this problem with vista 64-bit.

    Thanks in advance

    I really understand you, but there is nothing to see! Toshiba Vista 64-bit drivers are not available on the Toshiba page. Nothing!

    Of course, you can use a Vista 64 bit on laptops, but you will get not all 64-bit drivers. Maybe more later but not at this time!

    So either you will switch back to Vista 32 bit or you need to use this notebook without 64-bit drivers. But this is not recommended
