Can satellite A300-15J - I exchange the faulty card?

I think I can have exposed my soundcard of the A300 to too high voltage to the 3.5 mm jack. There is no device for playback/record listed (only connexant HD) and a hardware scan detects any device (Vista). I have a system dual boot, and the same thing happens if I boot into Win 7.

When I tried to start this morning there is a static sound from the speakers and white screen. A new round of power started the laptop with no sound coming from the speakers.

Anyone know if there is a replaceable module of its edge, or if the sound is integrated on the motherboard? Is it profitable to repair a Board if the sound is integrated? Is it possible that there is just a fuse or a discreet component damaged? I think that there is no provision in the BIOS or any device management utility.

> I think I have exposed my soundcard of the A300 to too high voltage to the 3.5 mm jack.
Out of curiosity, but what did you do exactly? I mean, how it is possible to damage the sound card via this port?

In any case, I m not 100% sure, but I think that sound card is onboard, and you will not be able to exchange it. I m afraid entire motherboard must be replaced. That's the big problem now, and I don't really know what should be the best solution for you. If possible try to contact an expert for electronics and explain the situation.

And there is another problem: where to get the sound module? It is not so easy for machines to find such components.

    Hello

    I have a laptop Satellite A300-15j.
    Is there no way to disable my Bell System?

    It's sound is very loud and annoying.
    I would have run a big mysql script with errors soon and my Bell system had become crazy.

    My cell phone sounded like an alarm and it was very awkward.

    Thank you!

    Are you using Vista?
    If so you could turn off the sound in Control Panel-> sound-> last sounds tab

    Here, you can choose the event program and can affect a new sound or disable.

  • Can satellite A300D-125 - I change the graphics card?

    Hello!

    My question is very simple that I write on the subject.
    Is it possible to upgrade graphics card on the model named "Satellite A300D-125 cm?

    I know it seems absurd for some users, but I have to say there are phones that you can update their graphics cards easily. On laptops from other manufacturers, you can!

    Hello!

    Why do you want to update the graphics card? Do you have any problems with it?

    Well, I n t have good news for you because it of not possible to update the graphics card on this laptop because the graphics card is soldered on the motherboard.
    So I prefer this Toshiba document: http://aps2.toshiba-tro.de/kb0/FAQ7A01ZW0007R01.htm

  • Can satellite A300-1MT - I put the CPU?

    I was wondering, can I upgrade my T3200 2 x 2, 00GHz, 1 MB 667FSB with another, which has more cache and maybe higher frequency?

    TNX

    A lot of people want to upgrade his CPU but to be honest, that's not very useful.
    A newer or faster CPU costs a lot of money, and maybe it will not work. Also, Toshiba does not support the CPU upgrade.

  • Satellite A300-15J - keys on the keyboard

    Hello

    I got my laptop about a week now. I liked it carefully, the brilliant keyboard did irritate me at first, but... But to my surprise... this morning the left low corner command button was loose... it seems that one of the "connectors" broke up.

    Of course, I know what to say, I broke it, and it's probably true, because I type on my computer and so to put pressure on it... BUT, I have a respect for computers, I don't hit my computer and I have typing skills...

    I called a local computer company and they said that I need to replace the entire keyboard... because Toshiba will probably not fix it under warranty because they will say I did damage... I had a toshiba A100 for 2 years, the keyboard still works fine...

    I wonder if anyone has any suggestions or comments on this topic?

    Thank you very much.

    Well... sad story, but the fact is that the key on the keyboard is broken and the keyboard needs to be replaced.
    I don't know why it broke... maybe you used really too much pressure while typing... who knows. ?:|

    I have two Toshiba laptops different... one is 5 years old and the other is about 2 years old and I never noticed any problem keyboard or buttons...

    So in my opinion, you had a bad luck... that's all.

    Good luck with your keyboard replacement...

  • Satellite A300-1EG - dead with the graphic card pixel problems

    Hello

    Not after two months of use of a brand new Toshiba A300, I had a dead pixel.
    Its only I guess, but what intrigues me is that it could be somehow merged with disorders, that I got with my graphics card.
    I had trobule with S-video use, there was a bad image, without collors.
    Is there a chance that I can have my screen replaced?

    Im still under warranty.

    Thank you

    Hello

    Regarding the dead pixel:
    > Is there a chance that I can have my screen replaced?
    I doubt that the screen would be replaced only due to a dead pixel.

  • Satellite A300-15J: missing software sound like on Sat A100

    Hello

    I got my Toshiba Satellite A300-15J 2 days ago. My previous laptop was an A100.

    Miss me the sound software that had my previous laptop.
    There was a tray for the sound icon and I could right click and select if I use headphones or speakers to the laptop.

    I wonder if there is no need to distinguish between the headphones and speakers to laptop on this system? If there is, could be directed to a link to download the audio software for this model. This Windows Vista.

    Thank you for your time.
    Leon

    Hello

    I presume that your previous A100 has used a Realtek audio Manager.
    The A300 does not use and does not support the Realtek audio chip, but it supports the audio chip Conexant CX20561 and as I m not wrong there another sound feature.

    Check your control panel-> * Smart Audio *.
    You must meet certain useful configurations.

    I have the best experience with DVD - R Verbatim and TDK discs. These manufacturers make high quality discs and never had any problems with it so that you try.

    In the worst cases, you must go to an ASP. They can check your laptop and exchanging the player if it of necessary.

    Dear members...

    Good day...

    I have a problem with Toshiba Satellite A300-243, I installed the Bios after you download from Toshiba Web site, and when it's over, he restarted the machine and did not work, just turned on.

    So if any body can help me to solve this problem, I'm happy.

    Thank you...

    It looks like that the BIOS update has no...

    What can you do now?
    Yourself you can do nothing. The only change is the authorized service provider. Technicians can try to reflash the ROM module

    Sorry mate, but in this case you need professional help.

  • Satellite A300 - grayish colors on the screen

    Where to play games on my Satellite A300 (PSAGCA-02W010) and looking at photos of all colors seem a bit dull and grayish. When I called they said them it could be "limits the display" and I could have looked but I would be charged $120 if it was because of the limitations, I was wondering if anyone else has had similar problems with screens.

    It looks like my companion of hewlett packard LCD display which is very old.

    Any advice would be helpful!

    I have Satellite A300 and colors on the display are clear and bright.
    What games do you play? Something in the dark?
    Have you noticed the same thing if you use Vista OS for the daily work as Web-based applications or in the office?

  • Satellite A300-1MH - cannot start the eSATA external HARD disk drive

    When I connect eSATA disk HARD Satellite A300 is locked and the HARD drive is not detected. I tried to connect the HARD drive with both eSATA - SATA + USB power cable Cable when it is powered OFF with the same locked A300 result.
    Reloading utility chipset change anything.

    PS. on another computer same portable HARD drive works fine in both previous cases
    Thanks for the attention
    Fabio

    AFAIK, the chipset drivers are responsible for the usb, esata functions but you already reinstalled it. Have you tried to remove the chipset drivers in Device Manager and reinstall again? If still does not solve your problem, it may be the operating system itself. Using the preinstalled operating system or Windows disk?
