Question about Toshiba Satellite 5105-S501 Notebook

3 Answers

Hardware problem... video related

Basically The laptop powers up properly but after windows is loaded the screen goes dark. I originally suspected that it was the inverter, as I was notified that is one of the weak parts in this model. I replaced the inverter, and it boots up in safe mode command promp but not windows or safe mode. Could it be the video card is bad?

    Well I have replaced the hardrive and the inverter, I have also tried to plug in an external monitor to it, but did not disconnect the inverter, and it did not work.

    When I try and load the system recovery from safe mode with command prompt/network it says that the TBIOS.SYS is missing, making me think that it could be the mother board?

    The Graphics card is also unpluggable from the motherboard as it is a "Go" board.

    Hey, thanks for all the help.



    The exact model number: Toshiba Satellite 5105-S501. The old harddrive worked, but when I took the laptop in to be diagnosed the people there told me that it was a hardrive problem, and I figured it was a good time to expand the memory anyway, so I got a new hardrive after transferring the contents of the other to an external, now plugged into my desktop.



    And when I try to boot to the bios (which I tried many times) It doesn't appear, only wants F1 for default.



    I tried F1, F2, enter, escape, and space, all with the same results, and I even tried pressing all the keys as fast as possible and still the same result...



    I use Windows XP home edition on the laptop. When it didn't boot the BIOS I suspected it could be the motherboard?

    Yes, I realized that after my buddy came back to town. We were able to re solder the broken (visibly cracked) solder until it booted up, and then managed to find another one.



    The clue that it wasn't embedded was that it was a go card... a sure sign that it was an auxilary at worst, and replacable at best. :)



    Thanks for the help, and I will be sure to keep that in mind :D

WOW talk about getting bad advice. First off the video card IS NOT embedded on the motherboard of this model. It is a 440 Go Card.

Problem: BGA chips on the video card have brittle soldiering.
I have been fighting for a class asction law suit for a few years now over this.

Solution: reflow the solder. you can find this on several forums about the video corruption problem with this laptop.

Proof: start computer in a cold area. will run fine until it gets hot.

BTW the solution is only a temporary fix, if it even works.

Good luck and welcome to the camp.

The notebook does not have video card that is built in video but you can try with a external monitor plug in the back of your computer but disconect the inverter if the problem is gone or if display ok then your problem is the inverter or screen and may be is your hard drive first pug the external and we will see whats going on

Hi,
No, it sounds like you need to reload the operating system.
If it is the video card, it wouldn't stop at windows, nor boot in safe mode/command prompt.
If it is the video, that's really unfortunate, as it's built into the motherboard.
Just try booting into the bios and see if you can stay in bios for an extended period. If it does, then Windows is the problem.
Good luck

    Hi again,

    Please tell me the exact model your laptop is.

    It appears as if the bios is corrupted and needs to be flashed.

    A bit tricky, but not that bad, if it fixes the problem.

    What is curious is why you have a screen only in safe mode/command prompt. You say you replaced the hard drive; was the screen having problems before or after? If before, how were you able to load the new operating system?

    BTW, which operating system are you using?

    Try to boot into the bios, as I suggested earlier. Either press esc repeatedly, then f1, or f2 (it depends on your model)

    If you can access the bios, and stay there for any length of time, it isn't a screen problem.

    Good luck

    Hi Guest,

    I suppose "bad advice" is relative.

    Sounds like you are fairly familiar with this model of Tosh. It also sounds like you are a litigious individual.

    The best answer is usually the simplest one. To attempt to resolder the chips on the video module may be no big deal to you personally, but to the average user, not reality.

    To obtain another video module might be do-able.

    By your own admission, " if it even works", we can conclude that you don't know if your solution is in fact a solution.

    We try to give advice based on personal, proven experience.

    We also try (sometimes it's quit difficult) not to diss another tech, no matter how bad the grammar or the advice. Correction is one thing. a put down is personal.

    Welcome to the camp.

My lenovo laptop G50 after loading windows screen goes black


Need to re-install Windows or:
- go into SafeMode and get rid of display driver (uninstall it); it could be possible that you have an update, and the new driver don't fit with your hardware. You could make something as "rollback driver". Anyway, you need to re-install your original video driver.

My acer has windows 7 and is showing an error msg of 0xc00000e9


The error message relates to a hardware error pertaining to your computer's BIOS. Basically it is telling you that the computer is not able to reliably communicate with the hard drive.

Is the hard drive suspect or have you just tried to reinstall windows?

Not booting


Would you be able to get the Windows loading bar before it goes to a dark screen if yes we could reinstall the Windows wherein you would lose information on your computer and to do the reinstallation all that you would need to do is start tapping on Alt+F10 as soon as you turn on your computer untill we find Windows loading files on the screen and then you would get the Acer recovery management Windows from where you need to select completely restore system to factory defaults and then keep following the instructions on the screen clicking on a few next ok or yes buttons and it would complete the process in 30-45 minutes time;if you are unable to get the Windows loading bar or the Acer logo then you would haveto conatc technical support and set up a repair for a video card issue.

When switch in on laptop it goes screen dark why


I'm not really sure I understand.
You apparently are able to turn the laptop on.
How long before it goes dark?
If it goes dark right after the Windows splash screen, then I would suspect it's a video driver problem. Try starting it in safe mode to rule this out.
If the screen does not go dark in safe mode, you've located the problem. You'll have to uninstall any video card software and download the correct drivers.

The short time it's working is about the overcurrent protection delay, it cutt's itself the Vcc, Vdd and control signals for limiting the fire hazard.

Laptop screen goes dark while loadin windows


If you can see everything when you shine a light on it, it's most likely a 'backlight' going bad. These are somewhat easily repaired, but can be expensive. Good luck!

Screen goes blank


Try to load to safemode by restarting the pc and hitting F8 before loading the windows, after you load to safemode right click on desktop screen and hit properties and check if you change the size of screen?or the setting there? also look for the device manager of your vedio card and check if it works properly.
If all this not working this means your vga converter has problem this is card inside your laptop mostly happen with dell laptops, if you donot want to change it now, try to see if you have external screen port and connect your laptop to external screen.
Let me know wat happen?

More information about submitted problem.


You have a failing video card or chip, you will have to determine whether you have a video card or a video onboard chip... if it is a card, you can replace the card.. if it is a chip, you need to replace the motherboard, or attempt a "rebake" of the video chip to the motherboard.
