• Black screen on boot - Toshiba Satellite M70

  Hi all

  I have Toshiba Satellite M70, I need help, and I will describe my problem:

  -A few days my screen went black all of a sudden, I don't know how do I was away from the laptop.
  -Until yesterday, when I start my laptop, it gives me the black screen all the time but when I put to sleep by closing the laptop for a few seconds and then I click the button, my screen starts showing very well until my next restart and I do it again (I usually keep my laptop running almost 18 hours) which means that there is a lot of time on my next boot)
  -But today I started too many times, it gives me the black screen and the sleep mode no longer works. But several times today when I tried to start, the display shows the Toshiba screen for only 1 second then black alley again.

  PS You can see almost threw the black screen just if there is a Sun facing the laptop.

  Thank you in advance,
  Best regards
  Mr. Mher Krikorian

  > You can see almost threw the black screen just if there is a Sun facing the laptop
  This is very useful information
  I think that the problem is related to the FL inverter
  FL-converter is a small part that controls the backlight of the display.
  If this part starts to malfunction so you would see everything as behind a thick fog

  In my view the FL inverter must be checked and replaced if necessary
  This, to get in touch with a local service technician

  Welcome & happy new year!

• Satellite A300 - black screen, Win7 is not booting

  I was working on my Toshiba A300 when suddenly Microsoft Security Essentials detected a threat, after cleaning it asked me to restart my laptop, after restart, it shows only the TOSHIBA screen with F2 and F12 options, but after that, else nothing happens. There is only a black screen, not even a cursor or anything like that.

  Nothing else happens, I tried to insert Win 7 bootable disc to repair the operating system, but my laptop does not seem to start through the drive, I checked the boot order in the BIOS settings, but still nothing, it does not accept the disk/USB nothing at all, it is not even go into safe mode by pressing F8 key continues to beep when I press any key regularly , I'm stuck & useless what to do, kindly help.

  It seems that the system on the HARD disk has been confused upwards and you will need to reinstall new OS.

  > I tried to insert Win 7 bootable disc to repair the operating system, but my laptop does not seem to start through the disk
  Insert the floppy disk. Then power on and press F12. Now, choose ODD (optical disc) as the boot device and press ENTER.

  The laptop boot from the CD?
  If this isn't the case, you should check if the laptop could start from any other bootable disk. This is necessary because you need to know if his problem of disk problem drive or an optical disc.

  Hello

  To be honest, for me it looks like a Windows problem. Maybe something messed with the registry and Windows can start t more

  I think that you must restore windows recovery disk Toshiba you wrote that you have tried to load the restore disc but what happened after that? Can start the installation of recovery? If so, you should do this.

  Backup, you can do if you buy an external HARD drive enclosure. Remove the HARD drive and install in the case of HARD drive. Now you can connect to another computer.

• Satellite P200D - black screen and does not just by running

  Hello everyone, I have a Toshiba Satellite P200D - 107 PSPBLE with configuration set-aside:

  Processor: Turion x 2 TL - 52 64-bit clocked at 1.6 Ghz
  Display: 17.3 inch
  Graphics card: Ati radeon x 1200
  RAM: 2 x 512 MB ram (1 GB total) which I upgraded to 1 x 2000 MB and 1 x 512 MB (for a total of 2.5 GB)
  OS: FACTORY CD WINDOWS VISTA HOME PREMIUM 32-BIT
  Power: Running on the direct power without the battery cable

  Although the pc is quite old sound fundamentally new barely there 1 year of normal use on it.

  PROBLEM:

  The screen goes black (no), even if the screen still has the backlight running, the laptop is still under tension, but its basically in a kind of deep hibernation with the fan running yet.
  The laptop screen turns off 5-10 minutes after windows loads, even if in idle, it also stops during installation of the operating system.
  I tried to run the music and the music stops when the screen goes black made all the hard disk activity which I believe indicates that it is not related to the video chip.

  TRIED SO FAR:

  1. open up the computer laptop and cleaned all dust processor, now CPU temp is 50 max, even for hard disk
  2. update the bios to the original to 1.70 - did not help
  3 connected external monitor also stops it the same time as the laptop screen indicating it is not not a screen issue
  4 reinstall OS several times
  5 tested memory with memtest64 - no error
  6. test the hard drive with hddregenerator - no error

  What I've noticed:

  If I leave just a 512 MB of ram in the laptop then the laptop stops not at all even in windows applications, tried to launch a game to remove video card and it works without problem for hours, but as soon as I add the stick of 2 GB or another origianal 512 stick it will go inside the black screen 5-10 min (or earlier) to get into windows.

  He never stops in dos mode (as in memtest, hddregen) even with 2.5 GB of ram.

  After that the screen goes black, if I stopped and then try to save, it it won't work at all, the screen stays black with the fan spinning and boot CD, I must absolutely disconect the power cord power and re - set before it starts again.

  Anyone has any ideas, I am experienced with the pc, but have never stumbled upon something so weird that I have just can't explain this problem that came straight from heaven.

  Toshiba to wake up, this forum is a total joke, you would think that you would be able to afford hiring a bunch of technicians to actually help people rather than rely on the users of the forum to do your work for your, you don't need to have a forum, if you don't have the staff to actually help people solve their problems.

• Satellite A200 - black screen of death

  Hi all

  I have a Satellite A200 PSAFCA-01K00J model. This model, I bought Harvey Norman in Australia, but I can't find any registration on the web site of current Toshiba or abandoned. This sux because I am looking for any bios updates available to address a recent black screen problem.

  The first time this has happened that I was able to reboot after removing the battery/cut the current to several times before its good. The next day, after an attempted works to install Kaspersky Anti-virus update the same problem... Power disconnected, removed, deleted drums (replacing the cylinder one and then the other to check the faulty ram memory cards) of ram and hard drive and then bled off residual tension with start button. Through this process several times before finally successful. I had to pass by it a few times since after restarts automatic windows updates, etc. I extracted the procedure to manually reset the bios by jumping it, but it's something I want to avoid doing this until I've exhausted all other options.

  Toshiba Satellite A200
  Model - PSAFCA-01K00J
  O/s - Vista
  Hard Drive - 160GB with 50 GB of free space remaining.
  System 32 with proccesors core duo. (intel)
  Bios Version/Date-phoenix Technology Ltd 5.20, 25/10/2007

  Any idea of sourcing on the last correct bios or any other input gratefully appreciate it... :)

  > Black Screen Of Death
  What happen exactly when you start your laptop?

  By the way: I ve checked the download from Toshiba on http://www.mytoshiba.com.au/support/download page and can not find this old model of laptop. I don't understand that Toshiba to THE is some archives for old models like on the page of European support.

  Anyway, I don't think that BIOS is the reason for this behavior.

• Satellite C650 - black screen after BIOS update

  My Satellite C650 Windows 7 - won't start afte BIOS update / switch.

  Everything worked very well until the automatic update of Toshiba asked me to download and install the new BIOS update, I did. At the same session Windows and McAfee asked updated. I agreed to all. After all updates have been installed, turns off. The next day when I walk, I see only black screen. I also tried F2, F12 and drive recovery. Nothing happens!

  Any recommendation?

  Hey,.

  It seems that something was wrong during the update of the BIOS and so that you can t the computer unbootable. But I put t understand why you did the BIOS update. If everything works correctly, you can forget about this update. More if you do a BIOS update you shouldn't t run any other updates or programs that might affect the update of the BIOS.

  Anyway, in this case you can do nothing and you need professional help. Please contact an authorized service provider and guys can help you update the ROM module On the Web from Toshiba site, you can find a list of all the FSA:

• Satellite A300 - black screen after long race

  I have Toshiba Satellite A300 1 portable PC series since 2008.

  It worked fine until the last few days. 2 days back when I started, it works fine until I go to bed (about 4-5 hours).
  "" I put my computer on and I slept, when I woke up in the morning, seen the button works / stop light is lit, "plugged in", "lit", "battery" all the lights are on but black screen of the tower.

  I moved the mouse, you press the mouse, press the SPACEBAR, enter keys on the keyboard, but nothing of this fact the live screen.
  I checked the fan works and the machine is hot normally.

  I noticed the CPU/HDD LED does not blink, the fact does not illuminate.

  The day before yesterday was also even, but after that restart was again very well.
  yesterday also repeated the same thing.
  Today also repeated the same thing.

  Please note my power saving mode: hip - turn off monitor - 1 minutes, turn the HARD drive - never.

  This setting is for last 2-3 years and normally off the monitor used to live on the movement of the mouse / key pressing.

  Can someone please help me figure out why my screen goes black after a night or more running morning.

  Thanks in advance

  Generally screen should turn off, but the laptop must continue to work.
  It is not easy to tell what happened.
  Can happen that laptop did restart because of a windows update installation?
  Some applications are active during the night? Some download or something similar?

  Hello

  It seems that something was tangled up in your Windows installation and the computer can no longer start t.

  In this case, you have only one option and that s reinstalling Windows. Therefore, you can take the (better) Toshiba Recovery disk or a Microsoft Windows XP disk. It will restore factory settings and your computer is read to use again.

• Satellite A500 - black screen when I start

  Hi all

  I was using my computer yesterday and it started to freeze all of a sudden, I held the power button and turn off. Today, I don't then restart.

  I have two options:
  1 repair Windows
  2 start Windows normally

  If I choose option 1, it loads the Windows files and then gets to a black screen with nothing on it where I can move the mouse. If I choose option 2, it is "loading Windows" screen and stays there.

  The black screen occurs if I try to boot into Safe Mode, repair windows, or start from another version of Windows 7 that I have on CD.

  Please help me on what to do. I have important data that I've not saved so I have reset to factory as a last resort only.

  How can I access my data? Should I remove the hard drive and put it in another computer?

  Any help is appreciated.

  Hello

  > Should I remove the hard drive and put it in another computer?
  If you have important data on your computer, you should do this to make a backup of these files. I would recommend so buy an external HARD drive enclosure where you can put in the HARD drive to backup all the files on another computer.
  But I think that I will never understand why some people don't have a backup. I think it s the most important thing and always make from time to time.

  In any case, it seems your Windows installation is confusing upward and, therefore, it of needed to restore the Toshiba Recovery disk factory settings, but the it will delete everything on the HARD drive.

• Satellite M70 - black screen on startup

  Hello!

  I have a problem with my Satellite M70-309, so for two times after logo Toshiba, Windows Xp (home sp2) does not start.
  The result is a WHITE & BLACK SCREEN.
  So I turned off manually appeared then black screen where I can choose if starting normally, last good configuration etc...

  That's happened?
  Is a hardware problem? Because my cpu died last month I changed it.

  Thank you!
  (Sorry for my English I'm Italian)

  Hi, RSC

  It is not easy to tell what can be the problem, but I assume that there is something wrong with the HARD drive. It will be interesting what happens with the new HARD drive.

  If possible also start the recovery procedure to see if the HARD drive will be recognized correctly and if the recovery procedure starts correctly. Check it using the installation in expert mode where you have access to information from HARD drive (partitions and so on).

• Satellite L300D - black screen on startup

  Hi guys, I need help please. On Thursday, I was on my computer and noticed that the weather was bad, I thought I have to do something wrong and were going to remedy. I went to my computer, but it wouldn't boot just had a black screen. I knew that I didn't damage the display. After a bit of research on Google I read to take out the battery and plug the charger in and low and behold, it worked!

  Friday, I charged my battery for an hour and put it in the computer and that worked too so I thought that the problem has been resolved.

  Unfortunately today my computer does not start with or without the battery to still get the black screen. Fan runs but apart from that very quiet sound. I tried putting the cd in see if that would be nothing, but it didn't.

  Any suggestions please?

  Try this:
  Unplug the AC adapter and the battery. Press the power button / stop along 30 sec.
  Connect the battery and the AC adapter and turn on unit t - it work?
  If this is not the case, connect an external monitor and check if something would be visible on 2nd screen
  If anything wouldn't show so I suppose you ve you have a motherboard serious hardware problem
