    So my Toshiba laptop started going black last night. Okay, so I would close the laptop then re-open it and it would turn on fine. But if I let it go too long its like it goes t hibernation mode (it doesn't). So I decided to do a reinstall of the system.

    I restarted the laptop, put my disc in, the laptop started to put I pressed F8 then the screen went black again.

    Now whenever I started the laptop, past the boot stage its just goes black.

    Have you tried updating the bios? The bios on most newer laptops can be upgraded with a usb thumbdrive and the press of a few keys. Even without a display.

    Looks like a memory issue. The thing boots and you see the bios, it gets warm and then bang it switches off or goes black.

    If the system is off then its the main memory, if its just a black screen then look at the graphics card.

    I guess I can't tell because nothing is moving. I can't get into BIOS. When I press F2 after a few seconds the screen goes black. I don't think its 'off' since I previous heard it made noise in the background. But I don't hear anything.

    If it is the graphics card, what do I need to look at?

    like for example, I closed it then opened it (the physical laptop), when I do this, the screen will function for like a second then its black. Again, starting Windows I see the screen for 1 second but then it goes black.

    So likely the graphics card?

    the computer is not going off, its still running.

    Sounds like it's either the graphics card or a loose cable, I would suggest running a livecd but since it won't load the bios menu that's not likely to have any effect.

    Edit: I'm a bit confused, it always Let's you get to the point of loading windows, but that's when it shuts off? In that case do download ubuntu, see if it will run.

    Its more like a graphics card thing, I think. So the laptop will start and run but after a few seconds its like the screen flickers out.

    If I close the laptop and open it again, the screen will flicker on for a second and I can see whats happening... by that point, Windows is starting up, or if I pressed F12, F8, its waiting for me to select something on the menu. But only for a second.

    If Windows was loading, it just loads Windows and I can hearing Windows start up. I just can't see it.

    Does an external monitor work even if the laptop screen goes out?

    Its Ram Memory - Had the same issue a few months ago with old Toshiba laptop.
    It has like 3GB ram, when I removed 1GB was working perfectly...
    Try to play with Ram.

    Good Luck

    Had the same issue a few months back, turned out to be a loose fan cable, the laptop would start and then overheat. Opened it up soldered the cable and it ran fine, with video card you usually have strange characters showing up on screen giving you a warning it's about to die, I like the memory idea too, worth trying those one at a time before opening everything up.

    So here's a interesting update:
    I'm reformatting the computer and reinstalling a new copy of Windows XP (different reason). I don't have an external monitor to hook it up to but I agree that its likely something to do with the LCD monitor being back lit.

    So as I'm in the install it goes black but if I closed the laptop then open it again, it'll stay lit to where I was. So I'm installing a fresh copy now and it goes black, I just open it every once and a while to see if I have to press T or F8 or something to keep the installation going. It might be the fan cable? But the laptop still runs.
    also I can hear the fan running

    I recommended hooking up an external monitor so that you can determine if in fact it was bad LCD screen or the system overheating. Borrow one from a friend if you have to; it sounds like a simple five minute test.

    I'll try, I don't know anyone that has a monitor.. everyone uses iPads, laptops, etc.
    So here's an update. I found that I think its a lighting thing. I can barely see the screen. Like its not backlit or something. I have a browser open and can hardly see that its open. When I do Fn + F5 (I think its meant to displays externally to a monitor) it flicks back on and I can see bright again.

    Not sure if this has been covered above and I can't be bothered to read the entire thread as its late and having just got back from the gym and all but here's my $0.02:

    My friend had exactly the same issue with his toshiba laptop and the fix was just to get a can of compressed air and blast out the mountain of dust and dirt that had accumulated in there and which was causing it to overheat quickly.

    Hope it helps.

    Also, this is quite possibly the least helpful thing I've read online today, and let me tell you I've seen some ridiculously bad sales copy for IM products today :D
