The Toshiba power saver control modes and go into a low power mode, when the laptop is running on battery only.
You can change the brightness in the energy saver.
Simply configure the brightness of the screen to a higher level in the basic menu and you will get a clear view

  • Flickering screen or pumping on G560 during execution of a stack

    Hello

    I have a G560 with Windows 7 64 bit. When the laptop running on battery power the screen quite often wavers (especially in the half lower) or it looks like a light pumping. The laptop has an Intel HD graph installed. I installed the latest drivers from Microsoft Update, but it did not help.

    Any ideas? Maybe install the Intel HD (older) drivers from the Lenove homepage?

    There is a difficulty in the graphics driver's control panel. Under "Properties", go to the power. Then, under power settings, change "Power Source: for"on battery", uncheck" Display power saving technology'. " Click on apply.

    For any problem, reinstall Vista, contact the manufacturer of your laptop.

    Here is the General info on reinstallation of Vista:

    Vista recovery media obtain and/or use the Partition Recovery Vista on your computer to the factory settings .

    There is no Vista free download legal available.

    Contact your computer manufacturer and ask them to send a recovery disk/s Vista set.

    Normally, they do this for a cost of $ small.

    In addition, ask them if you have a recovery Partition on your computer/laptop to restore it to factory settings.

    See if a manual provided with the computer or go to the manufacturer's website, email or you can call for information on how to make a recovery.

    Normally, you have to press F10 or F11 at startup to start the recovery process...

    Another way I've seen on some models is press F8 and go to a list of startup options, and launch a recovery of standards of plant with it, by selecting the repair option.

    Also ask them if it is possible to do the recovery disk/s for the recovery Partition in case of a system Crash or hard drive failure.

    They will tell you how to do this.

    Every computer manufacturer has their own way of making recovery disk/s.

    Or borrow a good Microsoft Vista DVD (not Dell, HP, Acer, recovery disk/s etc).
    A good Vista DVD contains all versions of Vista.
    The product key determines which version of Vista is installed.

    There are 2 disks of Vista: one for 32-bit operating system, and one for 64-bit operating system.

    If install a cleaning is required with a good DVD of Vista (not HP, Dell recovery disks):

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu

  • Touch screen does not work on the old Portege M400

  • 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.

    Hello

    Eventually the partitions that appear on the HARD disk is corrupted.
    I couldn't install the OS on my laptop because the partitions have been confues up, I don t know why, but I couldn't format the HARD drive using the recovery disk.

    Finally, I took the Windows XP disc and formatted the whole HARD drive and deleted all partitions on the HARD drive. Then I installed Windows XP by using the Microsoft disk.
    After that, I made the recovery disc and installed the operating system using the Toshiba disc.
    Then, it was possible to reinstall the OS.

    Notes; The M400 seems supported RAID and therefore, you need to install the RAID driver first!

  • Set the rotation of the screen to external monitor on Portege M400

    I would like to be able to use the screen of the mobile phone in the form of tablets, while the display to an external monitor. The problem is that when you use the laptop in its Tablet configuration (fixed and swivel screen on top) the external monitor displays the image upside down. If I rotate the screen image output, so I use the Tablet upside which is impossible when it is docked. Is it all the same independently set the rotation of the screen of the Tablet and the external screen?
    If someone could help me with this I would be grateful as at this moment whether or not I have to remove the Tablet and use backwards the external monitor.

  • Portege M400: Resolution 1680 x 1050 on external screen is not available?

    Hi people,

    I just installed a Portege M400 with an external monitor from other manufacturers. This optimal resolution of the monitor is 1680 x 1050. I installed the latest Intel drivers available on the web site of toshiba with manufacturing monitor drivers. I can't get this combination in its optimal resolution. Can anyone of you help me with this problem please?

    One thing you need to know: the monitor works perfectly on another laptop... so it has nothing to do with the monitor itself...

    Thanks in advance...

    Hi Steve

    I think that you are not able to use this resolution because it s is not available in the properties of the graphics card.
    To my knowledge, doesn t graphics card driver supports different resolutions. Some of the resolutions are disabled or are not in the graphics card driver.

    Some users have solved this problem by using a different graphics driver, but this is only possible on models with the nVidia or ATI graphics cards.
    Unfortunately, I think that there is nothing to do.

  • Portege M400 - cannot install OS or restore an old image

    I have a portege M400 and im hardly set any operating system of windows on them. When it gets to the stage where he asks what hard drive to put in place the windows files to, it does not detect the drives.

    I also have an image on a hard drive that I use a universal driver restore program to restore to any laptop regardless of the make and model and which also blue screens after the logo of windows xp when it starts up. The toshiba is the first laptop that I fell on this issue.

    The BIOS is currently 1.8 I think, I can't even put the hard drive in compatibility mode or AHCI.

    im a little confused about restrictions of this laptop.

    Can someone guide me on what I need to do to install windows on this machine please?

    Timox is right: the RAID driver must be added during the installation of Windows XP.
    During installation, you will be asked to add 3rd third-party drivers. As I m not wrong not you must press F6 to add the RAID driver.

    Very important note: do not format the HARD drive once the RAID driver has been added because this would remove the RAID driver from the HARD drive and installing Windows XP will fail again.

  • Portege M400 - Windows XP cannot find the hard drive

    Hello

    Ive got a Portege M400 who im looking to get a new one, I never had the Tablet XP CD so im trying to install using an XP Pro disk, but whenever I get no hard drive can be detected and I tried another disc of publishing house also.

    Ive looked for SCSI / SATA drivers but can only find RAID drivers which are not good for me.

    I hope someone can help me

    Thank you

    Hi wacksonjackson,

    Why these RAID drivers are not good for you? Windows XP requires RAID drivers if your laptop is RAID controller and there is no other choice to install XP from a normal Windows XP disc. Then download the RAID drivers on the official website of Toshiba. Either you create a new installation with the RAID drivers disc using nLite freeware tool or you copy the drivers on an external USB FDD and load them during the installation of XP.

    Also check similar topics here in the forum. You will find hundreds of similar topics on SATA and RAID drivers.

  • 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.

    Hello

    I have a Portege M400 built from a unnatended installation, which accepts all Bluetooth, Screen Rotation, etc. Disk utility HARD drivers but it won't accept and install THE modem drivers. I tried the drivers from the Toshiba tools disk and two drivers XP modem on the Toshiba site.

    The modem is installed and works fine when using the product recovery image, but the drivers will not work after the installed unnatended be applied.
    The unnatended disc has also included modem drivers, but of course, they do not pick up any.

    Is it possible that I can get my Active Modem?
    Thank you very much

  • 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.
