• Satellite A200 - screen turns off without reason

  I have a Satellite A200-E530D on Windows Vista Home Premium. For a month, I had something strange happening on my computer, shortly after the start, the screen turns off. without good reason! the only option I have is hard to system boot and everythings... Although a few times after the restart he still went.

  I tried to upgrade to the last poster of drivers (I have an Nvidia Geforce Graphics card 7300 Go with 128 MB of VRAM)

  Another weird thing, Vista SP1 does not install on my machine. tried to uninstall my Anti virus, but that did not help either one.

  Can anyone shed light on my dark screen?

• Satellite M200 screen turns off after that start & battery does not charge

  Hello, I am from Jakarta, Indonesia
  I have a problem with my Toshiba Satellite M200 Notebook (running Windows 7 Home Premium)

  After I press the power button to the top of my laptop, it works fine display BIOS and Windows startup screen.
  but after that my monitor off all of a sudden when Windows is supposed to show the login screen.

  Sometimes, the monitor doesn't turn off, but shows a lower resolution (I don't know exactly what resolution, 1024 x 768 or 800 x 600, i use maybe 1280 x 800)
  so the only thing I can do is, press the power button to stop bad then press power again turns on, my monitor works normally
  try to stop and then turn on again in a few hours later, problems still comes once.

  from the moment where I install Windows 7, I use 8.15.10.1930 version of the driver (downloaded from Download Center of Intel, which included Assistant TV Intel)
  2 days ago, my friend told me that I should install the driver from the Toshiba site support, so I went to csd.toshiba.com and download the 8.15.10.1825 version of this site (which is not included Assistant TV Intel)

  my monitor works normally after I installed the driver I of csd.toshiba.com, so I think that the problem because the Intel TV Wizard somehow messed with my laptop. But this morning this problem once again, my turns just monitor suddenly...

  In addition, this problem seems to be my battery was unable to recharge, my completely reloaded Windows shows, but when I plugged my AC adapter,
  There are 15-20 minutes before my laptop turns off automatically

  Three months ago, I just brought my laptop to the local Service Center of Toshiba and bought the new motherboard to replace my old mobo (which have a VGA problem too!)
  Is there something I can do (related to Windows or driver/software) or I can bring my notebook at the center of service again?
  are they somehow an incorrect wiring when replacing my motherboard?
  and am I need to replace my battery too?

  I use this laptop for about a year and a half and there is nothing wrong with my battery before replacing the motherboard

  any help would be appreciated :D

  Hello

  Talk about your screen, the a graphics driver causes this malfunction with resolution and turn off. Go to the page of the toshiba driver and download the correct Vga driver for your model. I see, you are running Windows 7, if there is no driver for win7, try the vista driver.
  On your power supply, you have used for the year and a half and he is released in 20 minutes, there is nothing strange. It's standard for power supply operating period, need to be replaced. Just to be sure, you can check with a new battery. You will see that the trick works as expected.

• Re: Satellite L300 - screen turn off when it will be moved

  I have a problem with my screen stopping when I move my laptop or move the screen slightly. The computer does not turn off just the screen becomes black. I have to then hold the power button to turn off the computer.

  Does anyone has any ideas or had this problem?

  Hi Geg,

  You may notice this behavior on external monitor too?

  For me, this looks like a hardware malfunction caused by internal display or just the cable. You should ask a technician for laptop help.

  If only the cable must be replaced cheap s and takes a few minutes a technician for laptop.

• Re: satellite A300 screen turns off after the toshiba logo, will not boot from the CD/DVD

  Hello, I have this problem with Toshiba satellite A300.

  I deleted several files and folders of my drives C and E. To restart the computer, it only shows the Toshiba logo then a slightly gray white screen on a thorough inspection. Whenever I press CRL + ALT + DELETE, the computer restarts and behaves in the same way.

  I tried to use an external monitor, but there is no difference. The tent to start using a CD/DVD, same behaviour occurs, it does not start and screen remains blank after the Toshiba logo, I tried even to change g the order of boot, but in vain.

  What could happen?
  Thanks in advance.

  Hello

  It seems that you deleted system files and Windows no longer starts. Have you tried to restore the disk image factory settings or hard drive recovery? Or do copy the Windows installation... It is easier to reinstall rather fix the problem.

• Satellite A100: Screen turns off after a while of no action and cannot be reactivated

  Hi all
  I'm after a bit of advice/help. I have a satellite A100 & after its been on during an extended period with no keyboard (like DVD burning), the screen is empty. It does not matter the keys on which I support on I can't get it back. The only way to get out of what I've found is to reboot the machine.
  Any help would be greatly appreciated
  Thank you

  Hello Gary

  Try please install the latest display driver, you can find on the download page of Toshiba. It is also recommended that you update the BIOS with the latest version available.

• Satellite P100 - screen turns off

  Hello
  Two things...

  1 is this normal for the bottom of the laptop to be extremely hot and almost feel it burn?

  2. the other day, we turned my computer on, loaded but with a white screen. Throughout the day, he did this. I opened the computer and taken apart from the half of it, turned on and still nothing.
  The day after I turn the computer and the screen is on as if nothing happened.

  Any suggestions?

  Thank you

  I agree with baboon81. This behavior is certainly not normal and not much play with her. Contact the nearest service provider authorized as soon as possible.

• Satellite A100 - 784 PSAANE - screen turns off automatically

  Hi friends,

  I have a Toshiba Satellite A100 - 784 PSAANE with windows visa Home Basic edition.
  Now for 15-20 days I am facing a strange problem. The screen of the laptop emits a sometimes (not necessarily every time) and then when the frequency increases the display turns off automatically!
  Then I must Hibernate or he put laptop to sleep to find again the screen... Seriously, I don't understand the problem.

  Please help me.
  Thanks in advance

  Hi Julie,.

  It sounds as if something is harming your graphics driver causing the display to turn off. If the problem occurs only when you use certain applications or only started after installing a new application you may need to restore your system to a restore point before new applications have been installed. As a test, you can try to start your system in safe mode and see if the problem persists.

  I also recommend that you re-install your graphics drivers to see if it improves the problem.

  Other possibilities are that your graphics chip is a failure or overheating causing this problem in which case you have to return your laptop to a Service approved for the additional diagnostic agent.

  My last thought is that you may have a problem with the inverter FL (the component that provides the lighting of your LCD screen). Check, when the screen turns off, if you can still see a residual image on the screen. If yes then the FL inverter is definitely at fault.

  Kind regards

• Satellite 1800 - 752S - the screen turns off

  Hello world.
  I have a satellite 1800 - 752S.
  Since an ew months ithas a weird problem: the screen turns off. If I press and release the button the lid on what it is, but after that turns off again quickly. OT goes off sometimes immediately, sometimes after a few minutes, or even hours. Sometimes it provides be when I run out of battery and bothers me on AC, sometimes against. It works fine, after I turn sleep or hibernation several times, and after a reboot, it bothers me. I've updated his BIOS for the lates on this site, which would not help. I guess it's a hardware problem, because it's the same problem under Linux, and I tried to install different versions of drivers and windows (not only the one of the recovery CD). Anyone have the same problem before. Any help will be appreciated.
  Thank you very much

  Hello

  I think you're right, it's a hardware problem. But to be sure, try connecting an external monitor. If it works without problem while laptops, screen turns off, then it must be a hardware failure.

  I guess it's a problem with the FL inverter. You have to give your machine a service partner Toshiba for repair.

  Good bye

• Screen turns off when the Satellite A45-S250 is moved in the direction of less

  Hello.

  I have a satellite A45-S250. I had no previous problem with this machine. However, when the computer is running too long, or it is moved in the slightest way the screen turns off. I don't even have to type very slowly - or I lose the screen.

  But also, as I have said - sometimes I won't even be near the computer and the screen turns off. When I lose the screen if the light shines on it - I can see, it's always VERY fair Sun. Generally, it will come if I use the FN + F5 button.

  I don't know if it is a screen problem or a connection problem. It occurs with increased frequency. Any suggestion would be appreciated.

  Thank you

  Hello

  From your description, I assume FL converter is defective and must be replaced. FL inverter is responsible for the background light and the typical symptom for faulty FL inverter is dimming or blinking display.

• Satellite A210 - 17L - screen turns off

  Hello people,

  I have a similar problem to [http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=61255&tstart=15], screen turns off by itself randomly, but backlight remains lit and laptop always seems to work (judging by fan). This started after upgrading Vista to Windows 7 (new installation), there was no problem before. I tried to update the display driver, first ATI Catalyst, then Toshiba official one, the customer pays less often, but still doesn't work, it's nice embarrassing ;) It occurs regardless if the laptop is used or just slowed down and is not caused by overheating or saving energy, also cell is generally connected with mounted battery.

  I have the last opportunity to go and update the BIOS, but I'm in fear of bricking the thing, so he would try as a last resort.

  Any idea guys?

  Thank you

  Hello

  There is an easy way to solve this problem: connect an external monitor and check what happens. If everything is ok on the external monitor installation (Windows) and internal monitor are ok, the problem must be internal monitor itself.

  If it s the monitor itself it s inverter FL, LCD cable or LCD itself. That s is not easy to say on this virtual path for your laptop needs to be checked to an authorized service provider. Guys can make an accurate diagnosis.

• Equium A20 fell and the screen turns off always

  Hi, I was using my satellite A20 long (4 years). Never had any problems. Recently he fell and the screen turns off always.

  I can see the toshiba logo and the windows logo also when starting, and even I can enter the BIOS and change the boot order too... but as soon as windows load screen is black. I don't understand

  Anyone with the solution?

  Thanks in advance...

  Hello

  > but as soon as windows load screen is black. I can t understand
  This means that the display output has accidentally changed to an external.

  Have you checked if something would be visible on the second external monitor?
  Select this check box.

  In addition I advise to use the FN + F5 keys to check if you can switch the output back to the internal display.

• Satellite L300 - display turns off

  My Satellite L300 was working properly then the view is empty. I tried to reboot and the screen turns off after 1 second, I plugged a monitor and that works, but nothing on the laptop.

  But when I unplug the monitor, the computer screen turns on for 1 second then turns off. I tried restore but still the same sys.

  When you display on external monitor and use FN + F5 can you see all the video options?
  Is there an effect when you use only option LCD?

• Access code is lost as soon as the screen turns off

  When I turn my wrist after that my Apple Watch screen exploded, I need to enter the access code. I turn on the wrist, the screen turns off, I turn back, screen lights up, I need to re-enter the password. And so on and so forth. The watch does not maintain the code.

  I am white white, is not dense hairs on my wrist, no tattoos and I wear the watch very well on my skin.

  The funny thing is: it is a replacement watch, I got today. The other had the same problem, but this is probably because the bottom of the watch with the sensors fell, must have damaged the sensor cable. But this one is brand new.

  Hello

  Make sure the wrist detection is enabled:

  • On your iPhone, in the application of the watch, go to: My Watch (tab) > General > detection of wrist - turn on.

• Equium A200 - screen turns off

  Hi, I'm having a problem with my Toshiba laptop, the screen turns off randomly and the computer still seems to work, but when I use a VGA cable to connect to a TV it does not display anything.

  Here are pictures of when it fires
  http://Tinypic.com/r/vr9d7d/7 yellow on the disc tray is turned on
  http://Tinypic.com/r/2d9poya/7 that the front turned on lights and computer sounds like its operation.

  This led me to believe it's a hardware problem, but when I turn on the computer in Mode safe it never turns off. I also got the fixed ups this year because the screen was losing power.

  Can anyone help I can't really afford a new laptop at the moment

  Hi David,

  It's a little confusing, it doesn't always happen when you shut down the computer, or just sometimes?
  What do you do to get rid of this? Always remove the battery and the AC adapter or what exactly?

  I think that it s a hardware malfunction, usually has nothing to do with the software. What you can try is a BIOS update from the official website of Toshiba.
