Satellite L500 - noise Squeak and mic/noise issues

Hello
I hope you can help with my sound problems!

I have a Satellite L500 which is 18mth old.

* Something *.
In March, I had problems with my microphone / sound. If I had my volume of more than 50%, I would get a terrible grinding sound feedback that has been difficult to mute (IE due support on mute a couple of times).

As I got a 2-year warranty, I sent him away and they said they fixed it but is short-lived. The problem came immediately. The only solution I found to have its volume by more than 50% was to completely turn off the microphone.

* Two problem *.
For the last few weeks I've been to randomly make this top placed, continuous his squealing that occurs usually when I am in public with my laptop in my backpack (annoying!). I have to continue to support on mute for the squeal to stop. Interestingly, my cell phone is cut off when it starts. Sometimes, my phone is hot when it occurs. Is this overheating problem?

All the solutions for both of my sound problems? Should I send it to get my warranty repair? When I argued that it was not fixed the first time, they said Windows is probably corrupt and is not under warranty.

Thank you!

Kat

This should help you:

+ Hissing on the Satellite L500 +.

This problem occurs if the volume of the microphone in the speakers properties is enabled.
After you turn off this point the issue with Larsen is no longer in effect.

If this isn't a hardware problem but to question. With the help of right settings will help you.

  • Satellite L500 case, scratches and touchpad issue

    I have just a few problems with my L500.

    I got it for 2 months and I'm pedantic on this issue to the point that it is to be always in a bag when not used or on a desk when he is and I even clean it with a brush.

    Despite all this, looks like I got it for years. There are missing pieces of the case and scratches all over the thing and the small rubber feet or just the other side of the webcam takes off and fall thereafter.

    The mouse pad is also strange things, regardless of the settings I chose for her. Sometimes it won't work on the left side of the screen and will flick off to the right and I have to reboot the machine to make it work properly again or I have to tap several times so that he could do nothing at all or it scrolls crazily and I can't stop.

    Basically, it is under warranty, I am impressed by the fact that he is obviously made of poor quality material and is either damaged when I am taking care of him and I wonder if it is what I can do about it.

    I think abnormal wear is perhaps the case here.

    See you soon

    > Nevertheless, looks like I got it for years. There are missing pieces of the case and scratches all over the thing and the small rubber feet or just the other side of the webcam takes off and fall thereafter.

    Strange hmm what to say my L505 is a few months, but it looks like to buy on the first day.
    No scratch, nothing! Of course, I m safe with this laptop and use a microfibre cloth to clean it. I put t use on the road and I think that this is the reason why it's so pretty plastic covers looks like other common blankets used in other portable models so don t see big differences.

    > The mousepad also does strange things, regardless of the settings I chose for her.

    With regard to the touchpad.
    I think you should take a look in touchpad, configuration settings: Control Panel-> mouse-> device-> settings (or properties) settings
    Here, you can configure the parameters provided by the Synaptics driver.
    Notes; Touchpad uses two drivers: Alps and Synaptics
    If you have any questions, then an update could be recommended.

  • Satellite L500 is OFF and the Green LED flashes if hooked on sector

    Help!

    I have a L500 which is not outside the green light flashes when the power cable is plugged in, but does nothing else

    Hello

    What indicator do you mean exactly?

    DC (first on left) indicator lights up green when the properly feeding the power adapter. If the output voltage is abnormal or if breakdowns computers power indicator lights.

    The other indicator (power led second from left) lights green when the computer is turned on. If you turn off the computer to sleep, this LED starts blinking Orange.

    Also if there is a failure of memory Power LED repeatedly flashes
    0.5 sec and off 0.5 sec
    If there is a problem with the slot A the LED flashes two times orange then green once
    If there is an error in the B slot, the LED flashes orange green once then twice
    If there is error in the slot A and B the LED flashes two times in orange and green.

    But if the power light flashes green only, I guess there is a motherboard problem.

  • Satellite 2430-101: BIOS and many other issues

    Then... I had more than 1 question and I hope someone out there can answer...

    1 - is the new Bios (1, 60 - WIN) supports Hyperthreading? If not, is there an other BIOS that is compatible with the S2430-101?

    2. I want to replace the P4 2, 54GHz with a P4 2 8 GHz (800 MHz Bus, HT). If the Bios recognizes the new processor? The heat problem is not really a big problem for me, cause I plan to underclock (if its too hot for the old cooling system to manage) the P4 to 2.6. I want just the stuff (for example HT) of the new processor

    3. not the BIOS recognize a 120 GB HD?

    4. does anyone have experiences with the MSI mini-PCI combo (Blutooth/WLAN) card?

    5. the S2430-101 got a Geforce 4 420 go 32 MB... I was just thinking to upgrade to Geforce 4 440 go with 64 MB... Is this possible... His chip with several pipelines and so on... Its the same family... Has anyone tried replacing a laptop graphics chip? Perhaps a 'material-designer' Toshiba could give some comments to this :D Hey guys... Is this possible?...

    6 I need more power, I need more mAh: D... Do anyone know why the battery has more than 2 pins? Is there any material in the battery which tells the system information of the battery? If so, is it possible to build its own battery or system requires information from the battery in order to operate. If Yes, where can I get the specifications of this "battery pack material"?

    Thanks in advance... Stryker

    Hello

    I'm not an expert, but I'll try to help: :)

    1. There is no public list where you can read what each update BIOS contains or which issues are fixed. It is always recommended to install later and ONLY Toshiba designed update the BIOS.
    2. I can't give you specific information about CPU upgrade, but as far as I know, replacement of the CPU is often not possible. The processors used in laptops are connected to the motherboard using a process called TCP (tape carrier package). It is a method of permanent connection and it is used in the interest of the miniaturization and heat dissipation. For more information try to contact the Service partner in your country.
    3. you will be lucky if someone has tested with the same unit. This unit is about three years old and it is not easy to say what is the maximum size of HDD supported by the BIOS. I found the info set comes with 40 GB and you can use 60 or 80 GB HARD drive, and I think that there should not be no problem. If you need more space, you can use external HARD drive (unit has USB 2.0 and data transfer speed will be fast enough)
    4. I don't think you can use any card combo on this device because of hardware architecture. WLAN is here but BT module is missing and you can use an external solution such as BT USB stick.
    5 update graphics card is usually not possible.
    6. sorry but this question is a bit stupid to me :) and I really put t know how you want to use the battery clean.

    Expensive Stryker at the end I just recommend you to buy a new laptop. Believe me it's much cheaper than all your projects for the upgrade. Please think about it!

  • Satellite L500 - 1 7 and Windows 8.1

    Hello
    I can't install Windows 8.1 (Windows 8 will run successfully). Is - this 'by design' (maybe lack of support for things like EAP, NX or SSE2. see http://windows.microsoft.com/en-US/w...is-pae-nx-sse2).

    Thanks for help

    Frank

    If win 8 runs correctly on your laptop, then it should be possible to switch the Win 8 to 8.1 Windows too...

    In order to get the Win 8.1, install all updates to Win 8 and then access the Bank of Windows to get the update 8.1 Win.

    It should be possible to install the 8.1 update Win Win 8 is already up to date.

  • Satellite X 200-219 and power supply Issue

    About 2 weeks ago, my adapter has stopped working, I know its a problem with that and not a fatal outcome with the laptop.

    I know that I can buy one from here, but I really don't want to pay for one when I could ask a.
    I have a 1 year with Toshiba warranty which has run-out and also purchased 3 years extended warranty with the Comet UK.
    I was wondering if the adapter is covered on warranty toshiba or the comet.

    Any help would be appreciated.
    Bought a laptop from May 2008.
    Extended warranty expires in May 2011.
    Budget is pretty tight at the moment, otherwise I would have already bought for £80 of toshiba.

    In my view AC adapter is covered by Toshiba and you should contact or visit nearest Toshiba authorized maintainer and clarify this here.
    They can answer all of your questions and also help with ordering new parts.

  • Satellite L500 - external screen display after closing the lid?

    Hello
    I use the Satellite L500 - 120 Notebook, and before installing Windows 7, the laptop has a function very uncomfortable, when I applied an external display.
    When I closed the lid of my laptop, Office was shown on my display (with the native resolution of the external display) external, so I had not to
    change anything on the control panel. In Windows 7, Miss me this feature. I already tried to use the Control Panel, but there is no parameters, which fits
    with the previous ones. I can duplicate the screen in order to see my desktop screen on my external screen, but with the resolution of 1366 x 768 laptop.
    If I extend the views, then there is only the background image to the external screen, but this time with the native resolution.

    So my question is, how to conifgure Windows to recognize that I closed the lid, and the screen should be shown on my external screen?
    Or should I install applications Toshiba, that I had before, who visited account this function?

    Thanks for any help!

    Hello

    I m not a Windows 7 user because I want to wait until it will be released official, but I hope that I can help you a bit:

    First of all in power management, you can choose the action that happens if you close the lid (g. e. sleep, close, etc.). This action must be disabled because otherwise the laptop shuts down or something else.

    So I think that you need to install the display driver for your laptop. You can try the Vista driver because most of them are working on Windows 7.
    Then you should be able to define the correct screen resolution for external monitor.

    A working display driver is important to the clone or extends monitors to verify this!

  • Satellite L500 14 X - Fan switches do not properly under Fedora 12

    Hello people,
    I seem to have the same kind of problems with the fans of speed on my recently purchased Toshiba Satellite L500 14 X and Fedora 12
    The fan turns slowly until the processor gets 37 degrees. Then it runs at maximum speed, and never slowed until the reboot.

    I updated the BIOS to 1.60

    Now, in the Ubuntu 9.10 on the same notebook it WORKS CORRECTLY. When the CPU is hot on 37 or more senior degrees it starts to spin faster and when CPU back to 34 degrees, the fan slows down and works almost noiselessly!

    I tried all the options of the kernel: acpi.power_nocheck = 1, acpi = off, acpi_osi = 'Windows 2006', and so on — nothing has really changed.
    I tried different Fedora kernels, include 2.6.32 - nope...
    I tried to find a reason why it works under Ubuntu and does not work in Fedora 12... But have yet to find something fishy... And I think that the problem is somewhere in the kernel.
    The main difference I see is that on fedora 12 I can not install the proprietary ATI driver, who normally installs on Ubuntu 9.10. It is because of the xorg version in Fedora 12 and seems that we must wait for the next version of the ATI drivers.

    One last thing - in Fedora 12 notebook became hot very quickly and without reasons of course.
    In Ubuntu, it's not so fast and requires CPU load with something serious.

    I don't want Fedora to Ubuntu, just because of this problem of FAN (nothing personal :))) so I need to get this working in Fedora 12)

    Maybe someone faced the same thing?
    Any help much appreciated! :)

    Hey!

    I found the solution. Incredible, but the index is ATI owner driver. As I mentioned previously, the Fedora 12 version of the ati 9.11 driver cannot be installed due to the latest version of xorg.
    I reinstalled my toshiba with Fedora 11, install the driver from ati.com ATI and here us are :) now fans are working properly!

  • Re: Satellite L500-19 X - screen keeps going black

    Hello

    I have a Toshiba Satellite L500 - 19 X and continues to go to the black screen.

    When you start the computer it flashes briefly until start / Boot screen properly before going black right now. Sometimes, the image is displayed correctly for 3 or 4 minutes before also black.

    If you hold down / tilt the screen under a strong light you can see a preview of the ghost of what should be displayed and if you connect an external monitor to the external monitor works fine and you can see a black ghost of what is on the external monitor on the laptop screen.

    I tried to reinstall the drivers, but it had no effect.

    Do you think I should replace the screen inverter Board or just reconnect the connectors screen?

    Thank you very much for your advice.
    Concerning

    Al

    Hello

    First to solve this problem, you must disassemble the laptop.
    I put t know exactly the procedure step by step for the L500 series but this procedure isn't very easy disassembly and you could damage other parts.

    Back to the question.
    It seems that the graphics card is OK and the problem is with lighting.
    Satellite L500 was equipped with a FL inverter Board and LCD joint (no backlight).
    The FL inverter controls the level of backlight screen s and I think that in your case, this part is defective.
    To resolve this problem, he needed to remove and replace the s FL inverter.

  • Question about Satellite L500

    I just purchased a Toshiba Satellite L500, it works, and the first thing he does get in the Menu "system". This is what it is supposed to do?

    I chose the option of 64-bit and now it comes up with a big 'DANGER' all my data will be overwritten. HELP please... do I go ahead with the system recovery thing.

    It's a new brand laptop ever been put forward.

    This model of laptop is not known to me, but I assume that your laptop comes with Vista 32 bit and Vista 64 - bit operating systems. When you start it for the first time you make a decision that you want to use.

    If you choose the 64-bit version one is removed and you can use installed version only.
    So think twice before choosing OS you want to use.

    Later, when the OS is installed first thing to do is to create a recovery installation DVD. If something goes wrong, you will be able to install the operating system selected using this disk.
    "" For use of DVD creation please preinstalled "Toshiba Recovery Disc Creator. I am sure that shortcut to the quick start, which you can find on the desktop.

  • Questions on Satellite L500 - 19 X wireless

    Hey all,.

    Big problem with wireless on my Satellite L500 - 19 X and have no idea how to fix this. I am currently connected to the internet via an ethernet cable, and it is far from ideal.

    Basically the wireless seems to have disappeared! I had the laptop for a few weeks and it connected to my wireless network automatically and without problems.

    I turned on the laptop today, and there is no trace of her at all. I checked the HW configuration utility section and it says that the wireless switch is on. I tried to press FN and F8 to turn it on, but nothing happens.

    If anyone has any help, I would be very grateful because I do not know what step to take next and it's extremely frustrating in a laptop brand new.

    Thank you all.

    Hi grimaldo,.

    I also have no idea how you can solve this problem, certain important information because I can t find in your ad, e. g. OS, driver version, etc.
    You can add this information, please?

    At the moment I can only suggest that you need to update the driver. Just check the Toshiba WLAN portal to find a new version:

    On the underside of the laptop, you can find a product key that belongs to the preinstalled Windows 7. He touches s an OEM who only works with preinstalled OS.

  • Satellite L500 - 19 X - screen turns white (white light)

    Hello
    I have a Toshiba Satellite L500 - 19 X, and my screen is not working properly. When I turn on the computer, the screen turns off, but it gets lightened, it becomes white.
    The external VGA output works fine, I have no problem with an external monitor.

    I already changed the flat cable (Flex) that goes to the screen, but I got the same results.
    Can someone help me? What could be the problem?

    Thanks in advance!

    Graphics card is correct because you said that the external monitor is working properly.
    So I guess that screen internal or the FL inverter is the troublemaker.
    But that's just a personal opinion, I think that you will need to test the two parts
