Satellite L300D - black screen

Hello, I'm new here, I have a problem with my 3 year old * Toshiba L300D.*
Today I started my computer without an attaché of the mouse (I have some problems with the touchpad), I searched for some documents, found them and closing the laptop with + alt + f4 - stop +. Everything was ok, I used to work without a mouse, but after a few hours, I decided to start the laptop to copy documents on a USB key, but this time the * computer has not started, fans are up, the power led is green *, HQ is green (if I plug the power adapter) * and the battery is orange * (if the power adapter is connected). Do I have to mention is... that I use this laptop very well, and the battery was not customary for almost 1 year. I have updated the bios to the latest version of the bios, Insyde toshiba a while ago website, everything was fine, so far.

Another thing, _I have no beeps or nothing_, the * screen is black * until I stopped pc (remove the battery or the AC adapter), the power button 30 + s dosen't also affect the laptop, if I remove the two ram module the computer just reboots, nothing else. I disassembled the laptop, the motherboard seems ok, the HARD drive is ok, I managed to copy my files with a HARD drive rack.

I don't know what else to do. _Also if I turn on the laptop now F computer, the computer stops and the computer turns on again. _

If I understand you right display is dead, black, no reaction, no? You don't see anything on the screen?
I put t know if you can do but try to connect external monitor to your laptop just to see if there is a reaction on external display.
> Also if I turn on the laptop now F computer...
Why F? What would happen if you hold the F key at startup?

    Hello

    For me, it looks like serious hardware problem.
    What you can do is to test the device with an external monitor:
    Connect the external display and check if you see something like start screen for Toshiba, etc if you see something like that, then internal laptop screen is defective and must be replaced if not if nothing would seem-> the related problem of the motherboard.

  • 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

  • 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
    SMBIOS Version - 2.4

    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?

  • 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 L550 - black screen with mobile cursor on startup

    Hello world

    I have a Win7 of Toshiba Satellite Pro l550-17u with a startup problem, black screen with a cursor, but not going beyond.

    Tried to reset the default values on initial F2 menu configuration
    Tried to boot in safe mode and the safe mode with networking
    I tried Repair computer option
    Tried the restore advanced user
    Tried to load the recovery disk
    Tried to boot the laptop directly from the disc
    Tried to remove the battery, but made no difference

    When I get the white screen with the cursor, I tried a few things mentioned.
    Ctrl + alt + delete to get the Task Manager, but nothing.
    Pushin' Win + R to open the Run dialog box, but it does not work.
    Click on SHIFT 5 times quickly to get ticky key opened to get to the Control Panel, but it did not work for me.

    Last night did not turn on my laptop turned off but when opened I received a message that my system has recovered from a serious error, you click on close and then it turned off my laptop had this problem since.

    Next step i think I can reinstall the memory but don't really want to start taking it to bits.

    I also have a large amount of data I really want out of the hard drive. any suggestions?

    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 with two beeps

    Date: October 17, 2009

    I have Toshiba Satellite laptop computer * model A200 PSAFCA-01400J *. I am facing a problem of * completely black screen * (I can't see any image either). It happened twice more than the screen wouldn't turn on by moving the mouse or the touchpad. To turn on the screen I had to restart the computer. The screen worked well until it turns off again. Since it does not turn on even after I restarted my computer several times. I noticed that my * Windows vista home premium * load properly I can hear audio that indicates that I am ready to open a session. I also noticed the sound signal after slipping my finger on the sensor attesting that I connected successfully, but the screen remains black.

    When I turn on my computer, I noticed that it sounds two beeps, first beep is short and the second beep is relatively long. I tested the cover closing the cover switch and noticed that my computer goes into sleep mode and by opening the cover that Eve turns off and my computer turns on again; but the screen remains black. One of my friends suggested that the backlight of the screen inverter or the lid switch is defective. Can someone tell me what could be the problem and what do the two beep codes?

    Thank you

    Hi mate,

    Normally the beep codes at the start of average that it s something wrong with the hardware of your laptop. As Akuma said, maybe the graphics card or RAM must be replaced or other parts too.

    Have you already tried to connect an external monitor? You can see a picture on this subject?
    I don't know but maybe what he s m only internal something wrong with the monitor.

    In any case, I think you should contact a service provider for help. Technicians can check the laptop and fix it for you.

    Welcome them

    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.
