Satellite A200 - cannot downgrade the BIOS to v2.40

Please help me.

I bought a brand new toshiba Satellite A200 series laptop with vista home premimum inside.

For some reason, I'm not a fan of big vista.
So I lowered my XP OS and as I was looking for pilots and all this for XP I saw an update of the Bios for my laptop it's 5.20 which was for XP. Although for Vista its 2.40 as per mentioned on the Web site.

Now where my problems began.
I downloaded this v5.20 bios and updated.
Soon the problems began as laptop is overheated, it freezes and sometimes refuse to give performance.

As I was unable to find all my drivers for XP I switched to Vista using my recovery DVDs. But the problem remains the same with Vista too, so finally, I took my laptop to a Toshiba Service Center.

They have said that it is a motherboard problem so they fixed, but they have not set the Bios.
I still v5.20 on my machine.

I tried to go down to v2.40 but it always shows an error.

Can someone help me pls... I am able to boot with a USB but I don't have a version of DOS of Bios v2.40.

Please if anyone can provide me with my version of the bios.
I'll be grateful to her for ever.

Here are my system specs.

Date 2009-01-26 03:04:19

[Information on PC]
Model name Satellite A200
Part number PSAFCL-01M00P

Not even this when I buyed the laptop he showed me 749 something like a shared graphics memory now it shows only about 399.

I know that it is simply because of this update of the Bios.
Now I am not yet able to play good games.
This machine is almost useless for me now.

No help from you people will get.

I put t know why you want to downgrade the BIOS.
Have you read the information on the site of Toshiba for BIOS version 5.20? I created this:
> Support Windows XP and Vista OS

So I think that you should not downgrade the BIOS. The most recent BIOS 5.20 is for Windows XP and Vista.
You can find this information on Toshiba Asia because you have the model of Asia (not Europe):
http://www.PC.Toshiba-Asia.com =>
Update BIOS version 5.20 Satellite A200 (for the PSAF0-* & PSAFC *-* ONLY)

The Toshiba Service Center did a good job with the latest BIOS.

  • Satellite A200 - cannot find the sleep & Charge option in BIOS

    I learned that turn on "sleep dependent" in the bios of my satellite A200 will help my iPhone to connect with iTunes without freeze him. I downloaded the latest bios (2.50) and cannot find anywhere that will allow me to turn on "sleep fresh".

    Can anyone help?

    Hello

    If you can t find this option in the BIOS of your laptop doesn t are supported by this feature. With this feature, you can only load USB devices while laptop mode 'sleep'. It has nothing to do with the connection while the laptop is running.

    So I doubt that it can fix your problem. You must look for an alternative.

  • Satellite A200 - cannot change the language on the CD OEM Toshiba

    Hoping to find help on how to change my Toshiba Satellite A200 language Spanish to English.

    I asked a friend to buy me this laptop to Spain, unknowing it OEM came Spanish language and the recovery CD is only as only Spanish but I do not understand Spanish and I was wrong to go on the laptop because I don't want to click on the wrong thing in Spanish.

    Even when I install programs, it automatically installs in Spanish and it's really frustrating.

    Someone HELP!

    Your laptop was purchased in Spain, and therefore the Vista operating system is also in the Spanish language.
    You cannot change it to English without buying a new drive for Microsoft Vista in English.

    In some cases, it would be possible to install a MUI (Multilanguage) package for Vista, but it works with Vista Edition full (and businesses?)

  • Satellite A200 - I forgot the BIOS password

    I have a TOSHIBA SATELLITE A200 model that I brought on Dec 2007.
    I forgot the password I gave to the BIOS, and so far, of mar16th, I am unable to go in,

    I tried to fix it through centres of local services to Chennai and Tirunelveli, but could not get the success.
    I have also filed a complaint with TOSHIBA Service Center and went to TASHIBA in Chennai service center, and they said:

    (1) remove the BIOS chip could help, but it didn't
    (2) motherboard must be changed.

    In fact, I set password BIOS and of POWERON the same thing, then...
    Is there a way to remove the BIOS/POWERON password?

    The details of my laptop are
    Model: PSAFCL-01M00P

    I wonder why the ASP in your country could not remove this password.
    Usually, the unknown password can be removed only by technician ASP.
    You will not be able to remove it!

  • Satellite A200 PSAE3E: what the Bios update changes

    Someone can't tell me what efect will be a ubdate Bios on my laptop.
    This update can not damage the laptop?

    This update is a risk?
    P.S.: I use Windows Xp SP2, Vista not.

    Thank you

    Hello

    The update of the BIOS is only risky If you would use incompatible BIOS or use a wrong update procedure.

    If you have installed XP on your computer A200 laptop then a BIOS upgrade to the XP version would be desirable because of one of the main reasons.
    Without the version of BIOS XP your FN buttons will not work.

    So if you want to use the FN keys, the update of the BIOS XP is not necessary.
    But if you want to use the FN keys, you will need to update the BIOS to the XP version.

  • Satellite A500 - cannot update the BIOS (error message)

    Hello

    I have a PSAR3A - 02U002 Satellite A500 with BIOS version 1.9 is installed.

    After reading several forums, I discovered that there may be a BIOS (v2.0) update available to resolve the current problem, these Satellites have with overheating cooling switch down.

    Excited, I have tried to install the new BIOS - this is what I get:

    "There is an error occurred, please check below the elements."
    BIOS version more than 200.
    Battery capacity more than 10%.
    AC is fixed. »

    First of all, my BIOS version is 190, no more than 200. Second, I find it very difficult to believe that the battery must be less than 10%. And third, I don't see what that remove the power supply cable will do.

    Please note that this update of the BIOS found on Toshiba's European website, but v2.0 claims to be a worldwide release. I then checked on the Australian site and there is no BIOS for my model. I don't know how to interpret this contradiction.

    Help, please!

    Hi umm_excuse_me,

    So I think that BIOS update is not available at this time for you. European and Australian models have different model numbers, so I doubt that the update of the BIOS is always the same. The pieces of equipment may also be different.

    In your case, I would wait until the BIOS was released on the page Australian too.

    By the way: where did you read that this update was release in the world?

  • Satellite A200 - cannot download the display driver

    Hello

    I have the Satellite A200 with Intel X 3100 graphics card. I want to upgrade the display drivers. The only new driver for X 3100 is 7.14.10.1461 which is very large (146 MB) in size compared to those in the Intel support page (20 MB). With my bad connection, I am unable to download this driver. Why is this file so large? Is it possible to reduce the file size to the size provided by Intel?

    Despite, the Intel graphics drivers support page GM965 are 7.15 giving material support for SM 4.0 and OpenGL 2.0 + (AFAIK), in addition to many incompatibility has been resolved. However, in the Toshiba support page, the driver is very old (about a year and a half old). Is it not possible to update the drivers to those latest display?

    Thank you
    Sean

    Check to see if you can download the package in the coming days to view
    The packet size must be less than about 30-35MB ;)

  • Satellite A200 - cannot adjust the brightness of F6/F7

    Hello world

    First of all, excuse me for my English ;)

    So, I am owner of an A200 and I install my own copy of Windows XP because I don't like Vista (like many...).

    Under Vista, my FN - F6 or FN + F7 strives to set the brightness, but NOT XP. Can I use the FN - ESC to mute, etc, but NOT the function FN - F6 and FN + F7.

    I install the application 'Save energy', but after a reboot, it does not work. I see the icon (a small battery with both hands... one each side of the battery), the energy saver works because if I unplug my laptop, the brightness drops by a few degrees (and the icon for a bulb change 'orange'.

    So, here, something I miss to install or I did not properly confugure?

    Thanks for helping me!
