Upgrade Vista on the Satellite U200-126

I would like to tell my experience with the updated BIOS with my Satellite PRO U200-126.
I bought this computer last year, this is a Core Duo, not a Core 2 Duo processor. It has been working perfectly with Windows XP Professional.
All my problems began when I tried to upgrade to Windows Vista.

I bought an upgrade of RAM, because my computer has only 512 MB. I removed the keyboard and installed the additional memory module... It is ok. I bought a new SATA hard drive 160 GB, to install the new operating system on it. I bought Win Vista DVD. I downloaded all compatible applications and drivers from the TOSHIBA web site. I put the upgrade, so I started.

The first step was to upgrade the BIOS. My U200 had BIOS version 1.40 installed, and I flashed the computer with version 3.40 available in time on the Web from Toshiba website. I installed the new hard drive and started a new installation of Windows Vista.

The installation went smoothly. I upgraded to Vista with the patches required to MS and installed all Toshiba drivers and applications in the recommended order.
It was weird that the Toshiba web site had the drivers for Atheros WLAN card, while the U200 uses the Intel 3945ABG. I skipped installing these drivers. Today, I see that they have been removed from the web site. Good shot, indeed, Toshiba.

The first thing that I noticed that the ConfigFree and Intel Proset application have been crippled, if compared to those that are available on Windows XP. The ConfigFree Radar, for example, showed that the WiFi network name, not the single Access Points. Intel Proset was not showing the name of Access Points. It's ok - when a WiFi network has only one access point, but the majority of WiFi networks has several access points...

I learned that it is because Windows Vista manages directly, roaming access points while under XP, this operation has been completed the network adapter and its driver.
Since all software WiFi for XP (Netstubler's) work doesn t under Vista, the only way I was able to locate access points was by typing a command netsh prompt.
In my view, that Toshiba should redouble their efforts on their new software WiFi for Vista.

I was also confronted with other issues, but those issues Vista and not Toshiba. I want to only quote the new Vista network discovery protocol, the NTLM 2, which is incompatible with existing network resources like XP - 2 K based computers and Linux - NAS function. Editing the registry shown on MS Technet for that matter, t has failed. If all goes well, a MS Service Pack, in the future, may solve this problem of backward compatibility.

I also noticed that the Toshiba power management utility had become a subset of Vista power management, it was more than the very neat screen that I liked a lot. In addition, the default value of mapped Windows Vista power button suspends - and not offshore.

Next - I noted that the Fn buttons didn't work unless Toshiba Flash Cards have been loaded and activated. I didn t like Flash cards, because they use a huge 50 MB of RAM. This problem has been resolved with a different BIOS upgrade to version 3.50, I found on the Web from Toshiba site.

Then I started to use the computer. I loved the Aero Interface and the robustness of Vista. I had to disable user account control, since then has been a little too much security, at least for me.
Then using the computer on battery power, closed the lid, and computer is spent in standby mode. Later, I opened the lid and started working again.
Here, I realized something was wrong. To make a long story short:
1. after suspend and resume, the computer will turn off more.
2. after him suspend and resume, battery life has been reduced.

It didn't take much to realize it was a BIOS problem. I did a clean reinstall of Vista and the problem remained. I had to physically turn off the computer with the hardware button, because it does not turn off when asked so, but only after an interruption.

At this point, I put in the old hard drive with Windows XP. The computer started fine, any recognition of the fingerprint was extinguished.
BIOS upgrades kill association of OS fingerprints, even if doesn't erase the fingerprints of the probe, information stored fingerprints are no longer usable which is from a pint of view security.
Then, I closed the lid of the computer, and he went to suspend. In XP, the computer with BIOS version 3.50 would not again. It would be rather reset and Windows XP was perform a restart of the recovery thereafter. The Bluetooth radio has been messed up on every reboot.

At this point, my U200 was not usable on Vista and XP. Toshiba Europe web site doesn't allow you to download of old BIOS, neither Toshiba offers a utility to save the old BIOS before flashing a new. I was ready to send to the home computer.

Fortunately enough, I found BIOS version 1.40 on the Toshiba US website. It was not exactly the same as I had before because it showed a generic start-up Logo Intel, while my original BIOS showed the Centrino Duo logo. The version and date were OK, and I flashed the BIOS on my computer. He went everything is OK

With BIOS version 1.40, Windows XP worked perfectly as before. Under Vista, the computer turning off after an interruption / resumption.
The Fn buttons work properly even with loaded flash cards with BIOS version 1.40 under Vista, the brightness of the screen was not controllable - even from the utility to save energy.

At this point, I left 1.40 BIOS and XP on my computer. I'll wait for Toshiba release a compatible BIOS back and the MS to release a Service Pack or a hotfix for the problem network.

At the end of the story, I would like to add a few comments.
I saw the sale the new U200 with Windows Vista preinstalled Toshiba. The new U200 has a Core 2 Duo processor, so I guess that the motherboard will be somewhat up-to-date.
I put t have a new U200, but I think that this new version doesn t suffer from the issue of suspension-recovery.
If anyone from Toshiba is reading this post, I would like to be sent by electronic mail to the original version of 1.40 BIOS that was installed at the factory on my machine, I mean the BIOS showing the Centrino Duo logo colorful start. My email is: antonio.maglione15 (at) libero (dot) it
Also, I ask Toshiba for check the BIOS version 3.50 on an older U200 with processor Core Duo and provide to the public a compatible version back from the BIOS.

Kind regards

Dear Antonio

Thanks for you long interesting history.
As you probably know not this forum is just a user-forum user and I'm afraid that you won't find anyone from Toshiba here m.
Anyway, as you said on the Toshiba page you will find only the latest version of the BIOS and the older versions are not available. This real s. Several months ago, I tried an older version of BIOS for my laptop but without to succeed.
A hint; The authorized service provider may downgrade the laptop to the old version.

In any case, I guess many Vista tools and utilities that are on the market are in a first time and updates might solve some strange behaviors.
I noticed that the BIOS updates are published from time to time. Maybe the next update of the BIOS will provide some improvements.

PS; Don't download and install the BIOS from other sources. European portable computers to use the BIOS from the Web of Toshiba Europe site!

    Hey Buddy,

    Have you tested different PCMICA for Compact Flash cards?
    Have you tested different Compact Flash cards?

    I think that in this case you don t have several options because you are using an adapter and such Jules Destrooper can still happen with adapters.

    I would recommend a card reader external that you can connect via the USB port. I also have a card reader USB in Kingston and it works very well with my San Disk Ultra 3 SDHC card. :)

  • Experience of Vista with a Satellite U200-115

    Hi.Just a little of my experience since the upgrade to Vista, in the hope of an orientation.
    U200 only bought it 4 months with XP Pro loaded. used Express upgrade to Vista.
    I think that I loaded the new Bios & drivers ok, but very fast, everything works no more. I could not repair the Vista installation had to install on my second partition. This led to 2 choices of vista boot up which I just discovered how to stop.
    Vista looks nice but...
    I keep losing my optical drive, I have to uninstall and then restart your computer.
    It crashes IE with the program image. Firefox blinking on the screen like crazy. Can only stop with the prolonged use of button / stop.
    Utility flashcards... what that all about?
    recovery when opening lid, slow, maybe needs to restart.
    Wireless, can make his choice if there is or is not all available networks... reboot again.
    I wonder if I can use the recovery cd to put XP on the original OS partition and back to Vista next year!
    Any comments appreciated

    HM, it sounds not very positive, but the crazy thing is, I have to admit your 'report' it s not pilot stuff, plus the operating system itself. I think that if they 'closed' with their OS werenâ´t they hadn´t so much probs thereafter. The manufacturer can provide some proper drivers and the system could be running.

    Thus, we can have some faith when they release SP1 for Vista. I think a lot of people waiting for MS.  :) Me too...

  • Problem occurred down the Satellite U200-170

    Hello

    I am new to this so forgive me if the question was already asked. I just bought a Satellite U200-170, it was the last in the store and I don't didn't want to wait 2 weeks to get the laptop so I bought the showroom model (which is in perfect condition). I did format the laptop because the store made 2 partitions Eaglets, I didn't. So when I was formatting the pc I have inserted the cd recovery (part 1/2) and the pc boots with all the necessary drives and utilities.

    Subsequently I have insert (part 2/2) recovery cd but nothing happened so I thought that all utilities and drives has been on the first cd. Now the problem is that I have a few problems when I want to stop the laptop. The types of crashes screen when windows stops so I have to manually shut down the laptop by pressing the key. How to solve this problem.

    I would also like to know what is on the second recovery CD.

    HI Grace,

    Please check your recovery CD to see if they are labeled as the 1/2 and 2/2 Recovery CD. You must also have a CD "tools and utilities" that contains various Toshiba Utilities and extras.

    If you do not have 2 Recovery CD then the complete installation process should ask you to change the first CD while the ANDS process loading install, after which the installation continues to load the second CD.

    Kind regards

  • Problem with Vista hit the Satellite X 200 - 20 s

    Sometimes during typing on vista, it will stutter and freeze. The time is very short. Is this a problem with vista or the laptop. The T7300 Core 2 Duo 2 ghz processor.

    Hello

    I have a Satellite Pro S200 and the same problem was with my camera. It s is not a hardware problem, it s more a driver related issue No. So, the best thing you can do is update your bios and keep your drivers up-to-date. Just check the download Drivers Toshiba site and make sure you have the latest drivers installed.

    I had resolved my stuttering (core2duo 2.33 Ghz, 2 GB RAM) by updating all drivers...

    That's all

    Good bye

  • Is there an automatic procedure to retrieve all the drivers on the Satellite U200?

    I have re-installed XP on my Satellite U200 and lost all drivers and settings. Is there an automatic procedure to retrieve all the? I'm a bit mazed by 52 varieties of the drivers available on the support web site.

    Thank you.

    Alexey.

    You are going to use the Toshiba Recovery CD or will allow you to install all the drivers manually.
    I guess the recovery with XP CD is not available for this laptop and therefore only the manually installation is possible

  • How can I see the amount of cycles of battery on the Satellite U200-181?

    I have Satellite U200-181, and I use it hard, each. I want to be ready replace my battery, when he has 400 cycles.
    How can I see the amount of cycles of battery on my laptop?

    You shouldn't see this. You will see that the battery capacity goes down and will be empty shortly after. No one says that you will be able to use the 400 battery cycles only. You may be lucky and the battery will be more long service life.

    My Tecra M1 is about 4 years old and still works with the original battery.

    Your question is quite unusual and I am really interested about new comments.

  • How to reset the password on the Satellite U200-181?

    Greetings!

    Sorry for my English.
    I have laptop Toshiba Satellite U200-181 and all documents of (check, guaranteed).
    When the computer starts, it asks to enter the password of the BIOS... I called in the service center in Russia, but they told me that they have no response Codes

    I have PC Serial No.. and challenge the Code... What I need to do now? I don t want to pay $ 70 for reset password... Please help :)

    Best regards, Sergey

    Hello Sergey

    Please don't be crazy about me, but you don't understand how it works. To reset the BIOS Center Toshiba password control needs code given by your laptop model. Shortly after, they send a new return code and after you enter this code, that the BIOS password is removed.

    Allowed only in your country service provider can contact Toshiba control center and service just to get back the information. With short words: private person like you have no chance to remove the BIOS password. I hope you understand why it. If this is not the case, let me know that I'll explain.

    Sorry, but you need to call the service.
