Satellite L450 - 16K micro BUG

Hi all!

I have a Satellite L450 - 16K with a bug of microphone here.
When the microphone is pumped 30 dB, it will so loud beep.
I don't know why, but without stimulation, just on the maximum volume, it works normally.
I tried the realtek driver, but the result was the same.

Can someone help me?

> I don't know why, but without stimulation, just on the maximum volume, it works normally.
Can use it without stimulating. What is the reason for this?
I can not say with certainty, but perhaps this happen due to the microphonic effect.
You know what I mean, right?

    The Toshiba UE driver page provides the package upgrade to win 8.
    It s for 8 Win, NOT Win 8.1
    This is why some tools and utilities may not work properly.

    Such driver Toshiba System can be found on the page of the Toshiba driver too.

  • Boot with Win7 32 bit and Satellite L450-36 problems

    A friend has a laptop Toshiba Satellite L450-36 Windows 7 32-bit which he thinks has been hit by a Virus. He went to use the laptop a few weeks 3 + ago and concluded that it would not initialize. Now, he has 3 daughters who, before this problem, much used YouTube and say that they were able to see updates Adobe Flash Player appear on the screen at regular intervals, but they have deleted the. When he came to talk about the problem for me, I offered to watch the machine that I have some disks that can cure or at least let me save records Paragon Rescue Kit, Avira Anti Virus Rescue Disk, AVG Rescue Disk & others.

    When I turn on the machine I get a screen with boot Toshiba Leading Innovation one
    Press [F2] for INSTALLATION, press [F12] to the lower boot device selection menu. I leave the machine in operation and a window pops up let me the choice of {HD1}, , , but nothing happens when I select one, then I stop the machine and start again, this time by pressing F2 which takes me into the BIOS. I put in a cd, Paragon Rescue Kit 11, arrived on the BIOS and the CD starts. I did the same thing with the Avira Anti Virus system and it found 4 infections. He then lets me copy all my friend (s) files on an external hard drive, which allows me to complete objectives.

    I started the Recovery CD/DVD Toshiba product and I get a Windows loading files message followed by a bar of Microsoft Corporation loading under him and then there is a black screen with a cursor on it. I did the same thing with a system Windows 7 32-bit repair disc and get the same result black screen empty.

    I am retired and to my knowledge has been gained since the Commodore 64 days, then Amiga and PC now, but it isn't enough for me to fix this problem. I found very frustrating to be able to use a Linux program and see all the programs on the PC, but not actually being able to restart it, and start them! I could probably Boot & Nuke the hard drive, but my friend wasn't t provided with a disc of Windows 7 o/s system couldn t so re-installed without buying again.

    I would be very grateful for any advice on how to get rid of the HD1/FLOPPY/NEXT HD window and a solution for the portable computer so that it starts properly. I took pictures of different screens on the laptop that I could pass if they would help.

    In my opinion, you should remove the HARD drive and connect it to another computer and perform low level set in shape and just delete everything. You can use a tool like this and after doing this put back and try to install the original recovery image using the recovery disk.

    In the past I ve never had these problems, but I think it's the best way to remove all the viruses or malicious applications.
    Test it and thanks for posting comments.

  • Satellite L450-136 no longer charge with the AC adapter

    I was wondering if someone can help me.

    My laptop Toshiba Satellite L450-136 charge is no longer with the AC adapter.

    It is now run out of dead and the battery power.
    I don't know if the problem is with the computer or the power cable.

    It was working fine yesterday and then not work this morning.
    Nothing happened as the computer having fallen or anything.

    Does anyone have any ideas on how I can understand the problem and then fix it?

    Thank you!

    To be honest, I have two different laptops Toshiba (U400 and Tecra A11).
    The two race perfectly and never had problems charging the battery or similar
    I have other laptop which is 8 years from another manufacturer but the battery is dead, but it's nothing unusual for laptop that is so old ;)
    One of my friends has the same laptop as your Satellite L450 and this also works

    > I don't know if the problem is with the computer or the power cable.

    This can be verified if you would connect a power adapter new and tested.
    However, I think that it s not worth it to buy a new adapter only to run some tests, this should be done by technicians for laptop
    If your warranty is still valid, get in touch with the ASP guys and check this box

  • Satellite L450 (PSLY0E) - a black screen after BIOS update

    It seems I have "brick" my phone during a bios utdate that went wrong... black screen as suspect: o.

    The laptop is a Toshiba satellite L450 (PSLY0E)
    The new bios image is named "bwaa150a.rom".

    Anyone know if it is possible to recover the bios of the flash or floppy drive, using a sort of toolfrom recovery inside the bios chip?... .or something?

    Anyone know who is the manufacturer of this bios?
    If I rename the bios image during a recovery, what 12xxxxx be named?

    To my knowledge, it is possible to reflash the EPROM module using the special procedure of crisis of the BIOS. But this crisis BIOS disk for Toshiba computers laptops isn't available for download.
    This must be done by authorized maker Toshiba.

    But I also read in the forum about those who tried some discs of crisis 3rd party BIOS.
    Sometimes it worked, but in most cases, you need advanced help technician.

    However, to use the forum search option advanced to search for similar topics on crisis disk BIOS. Otherwise, as I said above: you last chance might be the ASP.

  • Satellite L500D - 16K - where to find the new updates?

    HY guys,.

    When I bought my Satellite L500D - 16K, I complained in forums dedicated to this notebook page contained very few pilots. After some time, a week or two, she 'suddenly' populated with drivers for everything. Now, after verification not for awhile, the model everything just disappeared from the model list! There is no L500D - 16K here!

    The automatic detection tool, which has worked before, now says your model is not found. Even if I search by serial number, the system can not find! Is not professional at all.

    Any idea where I should look for to see if new updates appeared?

    Hi Glady,

    What Toshiba page you are looking for exactly?
    AFAIK Satellite L500D - 16K belongs to European laptops models and so you must search on this page:
    http://EU.computers.Toshiba-Europe.com

    On the European page click support & downloads > download drivers. The next page you will find:
    http://EU.computers.Toshiba-Europe.com/innovation/download_drivers_bios.jsp

    He's looking for series Satellite L500D and PSLTHE and you can find the new updates for her! :)

  • Satellite L450-188 - how to disable ACPI.sys and update the BIOS?

    Hi, hoping someone can help me with a slight problem, I'll have

    I recently bought a Satellite L450-188 (number PSLY0E-03K019EN) running under Windows 7 64-bit

    I use the laptop with a DJ program called Rane Serato Scratch Live, I got latency usb problems, getting usb dropouts when I try to use the program on the smallest audio buffer position (which I expect to be able to do)

    When I contacted support at Serato team with my problem, they suggested that I run a program to check the time DPC on my laptop, when I presented the report to them, they said ACPI.sys was the origin of the problem and suggested that interest me to turn it off, but I wasn't too comfortable with that.

    The other suggestion was to try to find updates the bios for my laptop, but I'm not too set up with that sort of thing, and I'm worried I might damage the laptop maybe installing the wrong thing.

    Can someone give me advice on this topic, because I don't know what to do

    Thank you
    Jim

    Hi jimbob_1,

    Normally the ACPI means Advanced Configuration and Power Interface and control options for energy savings.
    So if something is wrong with the ACPI.sys file I recommend reinstall Windows using Toshiba recovery disc.
    By the way: are you running pre-installed Windows version or another?

    As Akuma writes that you can download the BIOS update from Toshiba Web site. http://EU.computers.Toshiba-Europe.com/ > support & downloads > download drivers

    Your laptop belongs to the series of PSLY0E, so you can download latest BIOS.

    Before you begin the BIOS update, close all running programs and extract all the files from zip archive. You start the update as an administrator and connect the AC adapter. Also, make sure that the battery is fully charged.

  • Can satellite L450-136 - I install Windows XP?

    I just got a Satellite L450-136 with Windows 7 and all loaded Toshiba Utillities. I don't like Windows 7 and many prefer Windows XP.
    Can I remove all Windows 7 and install Windows XP on this laptop?

    Thank you.

    Hey,.

    > Can I delete all Windows 7 and install Windows XP on this laptop?
    Of course, you can install all the BONES you want :)

    But don t forget to create the Toshiba recovery disc as mentioned in the user manual. If you want Windows 7 returns with all the drivers and tools you can restore from recovery disc because it contains a picture of the factory settings.

    Did you check if you can get all the drivers for your model and XP?
