Satellite P850 almost nothing works correctly after Windows update 8.1.

Model: Toshiba Satellite P 850 part number: PSPKFV-00H002AR

Machine is purchased in UAE (United Arab Emirates) UNITED with Windows 8 installed at the factory. Doesn't have a 3d screen. Doesn't have the capacity of Blu ray.

I have the following problems: most of the stuff does not work properly after that I updated to Windows 8.1 Although I followed the manual of Toshiba.

Some of the function Fn keys do not work.

Eco button does not work (even if it does not work in Windows 8 also)

Accelerator drive HARD does not work. says "caching works correctly", but when I go into the history of the use it has not been used since the day wherever I've updated to 8.1 Windows

There is NO driver for the built in LAN card (manufacturer Realtek)

The following solution is possible: uninstall all the drivers/utilities Toshiba and registry clean (with backup of course)

Go to download Toshiba Driver and select the 64-bit Windows 8 operating system (I guess that's for computers with pre installed Win 8.1 at the factory?)

Download any supplied drivers and see if everything works.

(I always download my drivers on Toshiba EU website (no question of machine is bought from UNITED Arab Emirates) because I don't see any difference in the files and Toshiba MEA Middle East and Asia Web site is slow and does not work most of the time.)

Also is there a manual with good order with installing the drivers? I guess that's something like Chipset driver > driver for Toshiba system > Toshiba flash cards Manager > then all the Toshiba Utilities > drivers for LAN, WLAN, sound, video, fingerprint reader?

And one last question made Office Toshiba assist include the last HARD disk Accelerator utility? If not, where can I download the latest version of work for my model/brand computer laptop that works with Windows 8.1?

null

> Some of the function Fn keys do not work.

To get all the keys FN works, installation of all Windows 8.1 tools is very important.
Tools such as: * System Toshiba Toshiba function key utility, utility Support Flash Cards, driver *.
You must look for each driver in the Windows 8.1 update 8.1 Windows 64 bit box

> Eco button does not work (even if it does not work in Windows 8 also)
You need to update/install the Eco Utility for Windows 8.1 update

> Drive HARD Accelerator is not work says of "caching works correctly", but when I go into the history of the use it has not been used since the day where I've updated to 8.1 Windows

Have you installed the utilities of the accelerometer and HDD Protection Utility for Windows 8.1 64bits?
Where n t, the mentioned tools are located in the area of 64-bit Windows 8.1

> There is NO driver for the built in LAN card (manufacturer Realtek)
It's the same local network as for Windows 8

  • Satellite Pro C850 - problems with WiFi after Windows update 8.1

    Hello

    I was wondering if someone could give some advice on a problem I have.

    Had an adjustable C850 Pro for a few months and worked well on Windows 8.
    I myself am then harassed and intimidated by Microsoft Update in order to install Windows 8.1 and in a moment of weakness, I succumbed (got sick of the nagging).

    Since that time, my wifi is very intermittent; either I'm on another computer write this and the laptop is essentially not connected to the internet.

    For some reason any (although I didn't try it before), I can not connect via ethernet either, so I think it's probably the driver problems. (I also tried to connect the public wifi but fails).

    I tried to install the driver WiFi Toshiba 8.1 but that has not solved the problem.
    Then I noticed that I'm supposed to install a bunch of drivers in the order.

    Maximum setting to do it, but the first package (associated with bluetooth) said I have to remove the current driver... I try by "turning off", then "Uninstall" but 8.1 seems to re - install automatically and I don't know how to disable this option (I can try to delete the driver file, I guess, but I'm sure 8.1 covered too and will probably launch a drone to try me out ", if I do). *

    Any kind soul there suggestions on a way forward? Pls.

    I see in the instructions of Toshiba Windows Update 8.1 should I have uninstalled the drivers before the update, but there is not much I can do about it now. :(

  • Windows XP PC freezes after Windows Update November 11. 2009.

    November 11, 2015, my desktop, operating system Windows 7, installed about 28 updates to Windows. When I then put running the computer and open Microsoft Outlook 2010, Outlook closed almost immediately and this message appeared: "Microsoft Outlook has stopped working. A problem caused the blocking of the program works correctly. Windows will close the program and notify you if a solution is available. "(I don't check other office software).

    After the problem with Outlook 2010, I rebooted the computer several times and each time has experienced the same problem with Outlook 2010.

    I used system restore to restore the system to before the updates of Windows, which included a critical update. Outlook, then worked correctly. I changed the settings for Windows Update to "Never check updates" so that Outlook is not yet damaged.

    Was it something wrong with the Windows updates?

    The problem was solved when Microsoft released a revised version of the KB3097877 update. Maxwell Joseph, moderator of the Forum Microsoft, announced this in the post, he created at 23:22:03 on November 12, 2015, on the thread titled "update KB3097877 crash.

  • Good question after Windows update on Satellite P100 PSPA3E

    I encountered a problem with my sound card after a Windows Update. It became an old analog tuner with problems of dust on his volume knob. (this is a reference "sounds like" for those old enough to remember) I updated the driver to the most recent DriverGuide.com, no joy.

    I even did a complete system restore "with the"product restore disk."" Which fixed the problem until Windows updated the right files for trash again. I don't know what files do the dirty on my card since most of the windows system updates are performed while I "continue to work! Anyone with ideas?

    Thank you

    JD

    Hello

    What operating system do you use? XP or Vista?

    Satellite P100 PSPA3E must use a sound chip Intel high definition audio Conexant CX20551-22.

    I recommend to remove the sound card in Device Manager after installing Windows updates.
    Then restart the computer and install the latest audio drivers available that support the sound chip HD Conexant CX20551-22.

    First of all, you should try to use the driver for the Toshiba page. If this does not work, check the Intel page!
    Please don t forget to restart the laptop after windows update finished.

    Hello

    • Have you tried the suggestions of Imran M in other post?

    You can view these methods:

    Method 1:

    Temporarily disable UAC and check if the problem persists.

    1. open Control Panel.
    2. under the user account and family settings click on the "add user account / remove."
    3. click on one of the user accounts, for example, you can use the guest account.
    4. in the user account, click on the link "go to the main page of the user account.
    5. under "Make changes to your user account", click on the link "change security settings".
    6. in him "turn User Account Control (UAC) to make your computer more secure" click to deselect the "use User Account Control (UAC) to help protect your computer. Click the Ok button.
    7. you will be asked to restart your computer. Do when you're ready.

    Warning: User Account Control (UAC) can help you to prevent your computer from unauthorized changes. It works by asking permission when a task requires administrative rights, such as installing software or changing settings affecting other users. We do not recommend disable user account control. If you turn it off, you must reactivate as soon as possible.

    Method 2:
    I recommend the clean boot and try to run the program.

    Configuration of your system in a clean boot state helps determine if third-party applications or startup items are causing the problem. If so, you need to maybe contact the manufacturer of the program for updates or uninstall and reinstall the program.

    See the following article in the Microsoft KB for more information on how to solve a problem by performing a clean boot in Windows Vista or Windows 7:

    How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7
