Satellite Pro P100 - multiple display after Exchange screen problem

My laptop: Toshiba Satellite Pro PSPA6A-028017 with Nvidia GeForce Go 7900GS

OK, here's the story. I turned on my laptop about a week ago and the screen is blank. I plugged in a monitor external via AVI and tried Fn + F5, but nothing. When the computer reboots, the external screen worked. When I tried to turn on/off displays the external monitor is turned off and I found myself with an empty screen - I was obviously spent on screen of the laptop but working blind, I couldn't work out how to get the external monitor to start again. FN + F5 did nothing.

At that point, I called Toshiba for the support of the warranty (on-site, next business day). They had a technician with new monitor/display on site the next day (after a few calls me to follow up). It has replaced the screen but struggled to lift the screen up and running. He finally managed to logon Windows safe mode and get running but only display on 800 x 600. It has updated the Bios and drivers. He could then up to the 1024 x 768 resolution. Highest and the screen would be left empty.

At that time we plugged in an external monitor via VGA. It worked, but the technician couldn't get the each display to run on each resolution. He left him speechless and he acknowledged that things still are not good. Later, after that the technician had left, I managed to get views working so each to their own resolution. However, I could not always connect the external monitor via DVI (VGA only). I was at least temporarily to work!

The next morning that I turned the laptop on to find that I was back was started. No display on the laptop and on the external monitor only low resolution. It seems that the external monitor is simply cloning which should show the computer screen.

Under the display properties > settings the display shows:
1. (multiple screens) on NVIDIA GeForce Go 7900 GS
2 Dell G2410 (Analog) on NVIDIA GeForce Go 7900 GS

I know that when everything is working properly, he said not many monitors. The only screen I see is the Dell external monitor. And when I identify the Dell screen is no 1, even if it's not listed number 2.

I don't know anything about the cards video etc, but a theory I have is that adapter is defective and is only show the analog signal. That is why I think that the screen of the laptop and external monitor (connected via DVI) works not done the external monitor connected via VGA (but it seems to be imitating the screen of the computer, allowing only the laptop screens range of resolution). Is that possible?

Someone at - it ideas? The problem is likely to be the video card? I'm puzzled. I'll have to get the technician on the spot back (which will probably still 2 days and several calls, follow-up) and I don't want to lose any time. I have a business to run and I have now lost a weeks work already. If I can offer some strong theories before the technician comes on the spot, sometimes we can get parts ordered in advance.

My warranty expires in a few weeks, so obviously I want this fixed correctly in the shortest time. I don't want to wait 2 days for a technician to come and have to wait another day or two for parts.

Help, please!

Thank you


It is not easy to offer the correct answer and explanation why this happens here on the forum. In laptop cases should be tested with diagnostic tools to ensure that what is the problem.
OK, exchange of display was a step in the right direction but, of course, this question is more complicated and doesn t happen due to the defective screen only.

I agree with Akuma and also thinking that there must be a hardware problem on the motherboard. Before the expiration of the warranty, you should contact the service again and let check portable equipment.
The fact is, if there is that no book of hardware malfunction should work fine preinstalled with delivered recovery image (Toshiba CD/DVD recovery facilities).

Please, don't wait too long and contact ASAP. They check your laptop. the warranty is still valid and your laptop needs to be repaired.

Good luck!

  • Satellite Pro P100 can not get the screen to work again

    If someone could point me in the right direction, I would be very grateful!

    I bought a monitor to use when I am in the office (it's a LG Flatron L225WT), installed the software that came with it and plugged. Nothing seemed to happen, then in Toshiba HWSetup, I changed my power on the screen 'LCD + Analog RGB'.

    To cut a long story short, the external screen works perfectly now, but I cannot access the internal screen, even after changing the power supply on the display to 'Automatic Selection '. The Fn + F5 key does not appear to have any effect at all.

    I must have inadvertently done something to mess up the computer. Can anyone suggest how I could reset it back?

    TIA to all who can help you!


    I put t know what laptop you have and don t know what OS you are using, but it seems that you have managed to set the external monitor as the main screen.
    You should change in display properties (right click on desktop-> properties)

    Somewhere in the settings, you should try to score the internal display (1) and should mark use this device as the primary monitor

    You won't find any similar settings or this will not help then set the operating system to the point of time at the beginning. In this case all settings will be reset!

    I have a P100 SatPro attached to a monitor external 19 "via a Dynadock.

    By default, whenever I start the laptop the screen resolution 800 x 600.
    I have to manually reset to my desired resolution (1280 x 1024, 32-bit colors).
    If I reboot at any time the resolution then default back to 800 x 600.

    It's driving me crazy! Why won't save the settings? I tried to reinstall the software with no joy.
    Operating system is Windows XP SP2 and I'm a full administrator.

    Any help or ideas appreciated.

    see you soon


    I m not 100% sure if this might help you, but I noticed a similar problem on the Tecra M4 anchored to the multiple dock Tablet.
    The update of the BIOS helped solve this problem.

    In addition, an update of the graphics card driver would be desirable.

  • Satellite Pro L300 - new partition after Exchange of HARD drive sizes

    Under 'Vista' with a 120 GB hard drive and needs space.

    Bought a 500 GB SATA drive. I'm afraid that the recovery software will set the new drive with a 50-50 Partition. This is the case or it will allocate 50 GB to E: / and the rest to C: /?

    As the manual States that if I change the size of the partition the recovery software will not re - install in the future?


    As I know the Toshiba Recovery disk always allocates 50% disk space for each partition. This means that the 500 GB drive you have two partitions with ~ 250 GB of disk space on each partition.
    If not or you want to change something, you can use the Windows disk management tool:

    I think the manual means that you can use t more the procedure for recovery of HARD disk if you change the size of the partition.
    But with the Toshiba disk recovery you are on the safe side and so you can always restore the factory settings every time. :)

  • Satellite Pro A300 Wireless resumed after sleep mode problem

    OK, so I have this little 'itch' which becomes little boring sometimes. When I take my computer in sleep mode, it takes a good 30-40 seconds my Wi - Fi is reactivated. I mean, that's when my computer wakes from sleep mode and I'm in my browser, I get an internet connection for a good 30-40 seconds. I was wondering if there is some setting I've accidentally changed which makes my laptop to do this? Because I remember my laptop no this when I got it.


    I agree with the user above. You should try the update the WLAN driver. Perhaps the current driver isn't working properly so an update should help you get rid of it. More recent and pre-tested WLAN driver that you can download on the official Portal of Toshiba WLAN:

    What operating system you are using?
    On Vista and Windows 7, you can disable in the settings of the WLAN energy saving feature Windows power management.

  • Satellite Pro P100 - screen and sound problems after upgrade to Windows 7

    Hi all

    I got my Satellite Pro P100 (model number is PSPAEE-00C006EN and the second digit of the serial number is '7') upgraded from Vista to Windows 7, and since then, some bugs seem to have had place - can someone help me on the following:

    -L' screen DIMS increments, irrespective of the fact that I have saved my power settings to stay on FULL (battery or sector)

    -No sound. Once or twice, the sound card worked and settings to say this works correctly (and you can see the movement of the graphic equalizer).
    In terms of PC knowledge, I would be 5/10 (so not a dummy, but certainly not a pro! and we tried a lot of the more obvious things)

    Thank you all


    1.) if the screen dim option doesn't properly work, I recommend you to reinstall Toshiba Value added Package. This package controls these functions, the keys FN and others. Visit the Toshiba page for an update!

    2.) did you check if the sound is muted if the equalizer work? In addition you can also try to update the audio driver might it work ;)

  • Behavior strange screen/video Satellite Pro P100-109

    I have a strange problem with my Satellite Pro (P100-109 model pspa3e 00n009du). I edge video card printing is letting me down, so if anyone has a solution so please help!

    Yesterday, while working properly since I bought the machine, I had a strange video behavior. Black icon arround windows not updated correctly etc.
    After a restart of the system, these problems seemed resolved, but it lasted just a view minutes.
    After awhile, I got a blue screen (BCCode: ea BCP1...) BCP4:00000001 SP: 2.0) learned Internet research that his had to do with the video driver.

    Symptoms of the display:
    -Vertical dotted lines shown on the screen of the bios toshiba (variety of colors)
    -Loading of Windows show a few vertical lines as well
    -After loading the clickable elements appear black (not titles of window - no buttons shown/rendering)
    -L' screen goes black every 4 seconds
    -System responds very slowly, but sometimes it seems that it works normally
    -mouse disappears
    -After awhile that I get a black screen, system does not answer more.
    -In windows safe mode (so do not using the nvidia drivers), the display seems to work normally

    DID the next trying to solve my problem in vain:

    -J' I uninstalled/removed the nvidia drivers and installed the last on the toshiba site.
    -Deletion of original and installed drivers drivers Guru3D site (also used the Driverutility from the same site).
    -J' I uninstalled/removed the nvidia drivers and installed the original
    -Upgrade to SP3

    Uninstalling the driver (in safe mode) and so to use a generic driver only seem to work.

    Anyone know how this can be resolved or are these signs that the nVidia GeForce Go 7900 has been roasted.


    Long story. short answer...

    It is really possible that your GPU chip malfunctions.

    I came to this conclusion because the laptop don t symptoms occur if the graphics driver is not installed.
    If the graphics card driver is installed the graphics card would go with the best performance and possibly graph questions would appear once again.

    I think that you can't do anything to what might solve this problem outside to contact the ASP in your country and ask for help.

    Good luck

  • Satellite Pro P100-327 no visual don't screen the bios startup

    Hi guys,.

    I have a problem that I think has been there since I upgraded my Satellite Pro P100-327 XP to vista Business.
    At the start, I have more no Visual on the screen until I see the windows logo. Computer works fine otherwise.

    Now a year and a half later I want to load Windows 7 and I can't see the bios screen. F12, F2 or esc. do not help me even if the computer does not stall but I do not see on the screen. I have the latest version of the bios and the nvidia drivers as far as I know.

    The only thing that I did not understand everything is the 'value added package' I think it's the small "HW" program, I downloaded the latest version and clicked on load HW in the control panel. Windows has asked if I wanted to go forward and I saw nothing else after that.

    thaks a lot if anyone can help



    For me, this looks like a problem of monitor settings but I don't know m.
    You are using an external monitor or have you changed the monitoring (from simple to double mode) mode?

    In your case, I could connect an external monitor and see what happens. Have you noticed the same problem on external monitor?

    In the worst case, there is something wrong with the internal display, but this should be verified by a technician of the laptop.

  • Broke the screen on Satellite Pro P100 - 1 1/2 "vertical white line

    I have a Satellite Pro P100 which is only 21 months old and have recently acquired a white strip to the bottom of my screen which is located near Center. I looked into the possible solutions for this and followed the instructions carefully to see if it was a software problem which he seems not to be. The only possible solution seems to be to get the screen replaced. I would like to know if there are many of you who have had this same problem because I'm disgusted that I need to get this replaced so early in his life.

    I don't even use my phone as a laptop (IE it transport etc.) it is simply sitting on my desk at home. I just checked my warranty and apparently it was submitted only for 12 months! Just my luck!

    If anyone has any suggestions on how to best to argue my case with Toshiba in get this replaced for free then the answers are welcome.

    See you soon,.

    > Only possible solution seems to be to get the screen replaced

    Either it's a display or the fault of the graphics card!
    You can try to connect the external monitor to test if the same would appear on the second monitor.
    If the question seems not on the external monitor then it s not a graphics card issue but possible display of the laptop problem.
    In this case, the authorized service provider should be able to provide more details and how to fix it.

    Good luck

  • Satellite Pro P100 - display 1440 x 900 upgraded to 1680 x 1050


    I have a defective Panel in my Satellite Pro P100. Model No.: PSPAHE - 001001GR.
    Currently, it is a sign of Lp171wx2 with a resolution of 1440 x 900.

    I can change it for this Panel: LP171W02 with a resolution of 1680 x 1050?
    Will it recognize kind of Plug-and-Play? Better resolution and running as before. Or does not recommend or not even possible?

    Thank you very much in advance,


    I think he can.
    I know that the different models of Satellite P100 were equipped with two type of poster:
    17.1 inch, WXGA + (1, 440 x 900), color TFT display high brightness of amorphous silicon.
    17.1 inch WSXGA + (1 680 x 1 050), color TFT display high brightness of amorphous silicon.

    I m not very good if you could use the LP171W02, but the laptop would certainly deal a 17.1 inches, TFT WSXGA + (1, 680 x 1 050).
    You can also order a compatible part of a Toshiba ASP in your country.

  • Satellite Pro P100-188: screen keeps blinking on and off at random intervals tension

    If anyone can help me with my computer so please PLEASE publish it because I have no idea of what is happening to her.

    I just bought a new laptop, a Toshiba Satellite Pro P100 - 188 Dual Core and I'm having a problem with it. Sometimes (not all the time) if the computer is plugged in or not, the screen flashes and repeatedly and then will slow down and its suspicious home.

    I have no idea what's wrong with it, I sent it to the store where I bought to be fixed and they just he sent to me, but the problem persisted. They say they have done tests on the machine and can't find anything wrong with it, but if that were the case, then it only would not have messed up again.

    What is just a software problem? The screen seems to flicker on and off at intervals irregular or not I'm in the middle of using it or not. All the drivers are the latest drivers and I admit now that I'm at my wits end.
    Any thoughts, anyone?


    This seems very odd. However, you posted that this problem happens sometimes and not all the time.
    In my opinion I n t think that the software could be responsible for this issue.
    Perhaps one loses the connection cable? But believe me; It's not easy to say what's wrong without diagnostic tests.
    You have suggested that you have sent the unit to the store.

    I recommend you contact Toshiba service partner in your country. Technicians must check the laptop.

  • Satellite Pro P100 (PSPA4A-005002) - no sound after installing Win7

    I've updated my laptop Satellite Pro P100 from Windows XP to Windows 7. I ran the custom installation of Windows 7 while I did not any problem of Windows XP system and I used a separate hard drive. This way I can reinstall the hard drive with XP and go back and use XP if I am not satisfied with Windows 7. Among the problems I encounter is that I can't ge the noise at work.

    The speaker in the lower right corner icon has a red x on it. In Device Manager, the high definition Audio Device a "this device cannot start. (Code 10) "in the State of the device. The driver installation of guard is the version "Microsoft 6.1.7600.16385 version dated from 13/07/2009" driver. I tried to install the driver (Vista) recommended in the page Web of Toshiba "Upgrade your Toshiba PC to Windows 7". This driver has not worked. Windows also displays the error message "Driver Installation rating: could not find the media for this driver device.»

    I searched the web high and low and all the recommendation I found does not work.

    If someone has encountered this problem and have you found a solution?


    Maybe you used the wrong audio driver. The 10 error always appears if an incorrect or incompatible driver was used.
    I recommend the audio driver again.

    As far as I know the laptop supports a Conexant audio chip.
    There are some models of different laptops that support the same sound chip.

    See the European driver of Toshiba page and choose for example the Satellite P300
    This assumption of the model driver audio Conexant and I recommend that you install this driver!

    I have a Satellite Pro P100-PSPAEE running Vista Ultimate. Recently, the screen started going black and white during the day. It does not seem to be asleep like nothing refreshes the screen. All I can do is hold the power button and restart the laptop. Have tried rash, the compressed air fan and have re - configure the minimum processor power management to 100%. Am still getting the problem everyone else encountered this problem and have you found a solution, I would prefer not to have to open the laptop and play with the heat sink.

    Don't you think that this problem could be related to problems of overheating?

    One question; have you noticed the same issue using the preinstalled operating system from Toshiba?

    I'm a newbie here & laptop but my companion got a satellite Pro P100 (Toshiba Satellite Pro P100-124 PSPA4E-001001EN) & it is my asked for help. Here's the problem:

    Laptop starts to go through the procedure of starting with lights coming and cd player starts to work the rotation of fans, but nothing shows up on the screen

    I said it could be the graphics card but could do with a starting point, I'm PC savvy but on the desktop, it's my first attempt at a portable computer so please be nice...


    Have you tried this thing?

    ->, remove the battery and unplug the AC adapter from the portable computer
    -> waiting for ~ 30 min 1 h
    -> connect the two parts again and try to turn on the device

    If this will not help, then it would mean that a hardware problem serious causes this problem and you will need to contact a Toshiba ASP technician to know exactly what s wrogn.

  • Satellite Pro P100: How to recover BONES after replacing HARD drive


    I bought a satellite Pro P100, and I want to change my hard drive
    I have the CD restored, but I think that this will not work with a new hard drive!
    What can I do to recover my windows?

    Sorry for my englich!

    Thank you

    Hey Phillipe,

    Your recovery CD works on what hard drive install you in your laptop. Are the only factors affecting the hard disk of your choice: -.

    1. compatibility of the BIOS (should not be a problem with the P100 model)
    This model mainly old laptop impact where the BIOS could not recognize larger drives.

    2 form factor
    You should make sure that the disc you choose has the same physical dimensions as your
    existing drive.

    3 speed
    Disks hard more quickly improve access times so check out 5400 and 7200 RPM. (there may be a problem
    with the generation of heat so 5400 RPM is probably better than 7200)

    The are no problem with Windows licenses as the license applies to the operating system itself and not on the hard disk on which it is installed.

    Kind regards
