• How downgrade the BIOS on Portege Z30 - B?

  Hi all

  I updated the BIOS on my laptop Z30-B-119, and it is much worse than the original BIOS, so I want to downgrade it.
  There is no way to save the original BIOS during the update and the previous BIOS is not available on the site.

  Someone has the original BIOS and knows how to extract?

  Maybe someone knows how to contact Toshiba technical team directly? (Don't see what they have implemented in new BIOS, I have no hope they read on this forum or user opinions).

  If you're wondering why I want to downgrade and what's wrong with him, see below for an explanation.

  I was convinced that the new BIOS might resolve the problem with the fan, which works well too early, but it turned out they made much worse! The fan will now light at 42 °. Seized 50 °, which was already a Toshiba engineers stupid choice, provided that the side of the CPU temperature is 105 °, so that they could keep the laptop quiet at least until 60 °, especially as many people's complaint of the fan in this model. Instead, Toshiba has done the opposite and lowered the temperature even more.

  How foolish choice their engineers do, I will never buy another Toshiba and will not recommend anyone buy their products. But since I have already made the mistake one bought a Toshiba laptop, I hope that I will be able to downgrade the BIOS or contact them to request an update.

  Let me know if you know how to do it.

• 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.

• L450 blocked to 0.77 GHz processor when it is on battery and can not downgrade the BIOS

  Hello

  It seems that the CPU of my L450 is blocked to 0.77 GHz speed when it is running on battery power and no matter how heavy the load, the CPU speed does not fit on the rise, unless I plug in the AC power cord.

  This makes the laptop a bit useless on the battery when you do something time CPU.

  This seems to be the unusual question, based on the quick searchand possibly related to the BIOS. I would try to downgrade from 1.16-> 1.15 or 1.12, but I always get the error "Failed to secure authentication of Flash", after you run the flash program and rebooted (when flashing the BIOS should start).

  I turned off in the BIOS the option 'Prevention of RollBack Secure' settings, so I guess that's not the question for not having to downshift.

  Does anyone else have this problem (with the speed of the CPU limitation or decommissioning of the BIOS)?

  I tried to change options in plan powers the window, like 'The Maximum processor state', 'Intel CCMP energy efficiency Settings. "

  I am running Windows 10, if any relevant information.

  OK, think about it.

  The fix was to disconnect the battery and the power cord for one minute. After that, the CPU is scaling its speed again normally.

  Good thing that this laptop model has a removable battery, I guess...

  I'd like to, I would have thought this before going through the demotion to 8.1 Windows, since the I suspected it could be a bug with Windows 10 or some of its pilots.

  I think that this problem was caused by my recent update BIOS of 1.12 to 1.16, but it's really just a guess.

• Can I downgrade the BIOS on my X201i?

  Does anyone know if it's possible/desirable to "update" sound BIOS to an older version? In other words, are there additional problems involved with decommissioning of the BIOS as the most common risks with the BIOS updates?

  What I plan to do is downgraded to the version released late June 2013, because there supposedly solves the problem of battery drain. No Lenovo apparently cares to answer one of my questions of how it is possible that I have a newer version of the BIOS that is currently posted as the newest one (I have installed since Oct-2012 of 1.40 - 1, 20; the most recent version, the new post-Jun-2013 is 1.40 - 1.15), or what to do about it. So I plan to go ahead and reinstall (by crushing) my current BIOS with one posted on the web site: 1.40 to 1.15. (I have very serious problems with heat like terrible battery upgrade to Pro Win8 dump station).

  I'm no expert BIOS, so I'm not aware of the risks or potential problems of decommissioning of its BIOS. Perhaps there is nothing for her and amounts to the same thing as any BIOS update/install. In the affirmative, please let me know. I'm in complete lack of reliable expertise.

  Thank you!

  I guess I'm for a clean install then.

  Funny TVSU suggested I have install the BIOS recently posted yesterday (finally!). I did, without any problem, and it has certainly supported the heating problem. I always battery only about two hours of time, however, down from almost 5 hours before the passage of Win7Pro to Win8Pro...

• Satellite R830: How do the BIOS settings password protected?

  Hi all

  I installed a software protection against theft in my Satellite R830, but he suggested that I adjust the settings in the BIOS so that it will start only from the hard drive, and to make sure that no one else can modify it (if it is stolen), the BIOS settings are protected by Word.

  Can someone tell me how to access the BIOS at startup settings upward?

  Hello

  You can set the BIOS settings by setting the BIOS password.
  If someone would like to change the BIOS settings, the password of the BIOS would be necessary.

  Have you tried to get into the BIOS?
  Check it out.
  But usually after the update laptop BIOS should properly work and boots.
  Have you followed the instructions on the BIOS update on the page of Toshiba?
  Maybe you did something wrong and the motherboard is damaged.

• Resolution of the webcam on Tecra S11

  Hi, I have a problem with my brand new Tecra S11 - 12R and hope someone here can help you!
  My webcam only works in resolution 1280 * 720 and higher, but all not more low resolutin :-( For example, I can't use Skype for the Visio.
  I installed TOSHIBA Web Camera Application V1.1.2.6
  Thanks for the tips.

  I think you're the first person who cannot use cam for Skype Conference.
  As far as I know in the Skype video settings there is no option for resolution changes if this is not important.

  OK you have installed the new software of the camera and it's good for its use, if you want to make some photographs of you or short record but you n t need for use with different messengers. If you can get out Camera Assistant software and then open Skype and check the video settings it.

  Cam is recognized correctly? You see the photo in the box on the right side of the settings window?

• How to change sound on Tecra S11?

  The sound sounds aweful! Which speakers could buy and replace in my Toshiba Tecra S11?

  To be honest I m really surprised by your question. Always is that laptop Tecra are designed for commercial and designed for use in offices, meeting rooms and the customer visit so the sound is not so important in the whole of the package. This is not portable multimedia, so you probably won't find any Tecra with high quality speakers inside.

  OK, I can understand you and maybe it's not a bad idea to have Perfect sound on this model of laptop, but I think this is the wrong place for your question. What you need is professional advice.

  I recommend you contact the nearest authorized maintainer and ask for help. They have service manuals and know what speakers are inside and what speakers can be integrated as a replacement. Maybe some high quality of harman/kardon speakers can be used for the upgrade, but that one is not easy to say.

  If you do upgrade successfully please let us know and share all information with us.
