Tecra A2: display brightness Fn F6+F7 does not work after BIOS update

Updated bios to 1.40 WIN at end of January. Since then F6 & F7 keys fail to increase or decrease screen brightness. Is this a coincidence or is the bios update the culprit!!??

Hi
Usually the BIOS update shouldn't have any bad influence on the Toshiba drivers and the OS performance.
There must be another reason for the FN key malfunction.
At first I would suggest to reinstall the common modules. Please check if it will help.

  • Sleep and Hibernate does not work after BIOS update X1 Carbon 20A8

    As subject title, did a recent Lenovo "System Update" on BIOS and other drivers, and since then sleep and hibernate no longer works, when i close the lid, it turns on by itself after 2 seconds.
    When i select Sleep or Hibernate in Windows 8.1 with lid open, it just behaves like a Restart command.
    Need this fixed! Any ideas?

    Try downgrading to your older BIOS and see if it works again.

  • Satellite Pro L100 does not run after BIOS update

    Ok the machine is a Toshiba Satellite Pro L100 PSLA4. Problem occurred during a BIOS update from the official Toshiba website. I downloaded the zip file, extracted it and activated the .exe file inside.
    The window opened by the .exe was a BIOS flashing program, the .exe also simultaneously wrote a new BIOS file to a temporary folder.
    When tried to use the program all I got was an error saying that it couldn't find the new BIOS to input.
    I tried again only to get the same error. I then left the laptop for several minutes and when I returned, I found a blank unresponsive laptop.
    By unresponsive I mean an obvious lack of BIOS functions i.e. power LED's not changing when plugging in of unplugging from the mains and the fact that I had to pull the battery out to turn the machine off. When the machine is turned on now all it does is check the drives and restarts (no display, no beeps)
    What do I do?
    The first thing that came to mind was to reset the BIOS.
    One problem, I can't find the RTC battery or a jumper switch.

    I have at least found out why this happened, the program obtained from Toshiba automatically 'attempts' to upgrade the BIOS upon activation. This means that the program engaged with errors without my authorisation. I don't find this very impressive from a company as large and powerful as Toshiba.
    Also it may be possible to fix myself if the BIOS installation instructions made sense, extracting the .zip file does not create three sub folders and pressing the F12 key does not start the laptop.

  • MacBook Pro Late 2011 Model - Does not work after Yosemite update

    i recently updated my OS to Yosemite and had in problems for two days but yesterday it ceased to work in the middle of printing a document.
    I need my laptop back up and running since I have school exams soon and vital information and files are in this laptop.
    i Have never had a problem with the laptop before.
    Issues that I have had
    logging in takes at least 20 minutes
    cannot progress further than that, desktop is blank and nothing loads, only the dock.
    battery drains extremely fast
    Safe boot does not even load
    I've tried clearing that VRAM and the other one.
    Cannot access anything at all
    This is appalling and at the worst possible time.

    Please describe exactly what you're doing and what happens.

  • ThinkVantage Toolbox does not run after BIOS update

    Lenovo ThinkVantage System Update Tool on my T410 ThinkPad (2518EWG) offered me download and installation of ThinkPad BIOS Update Utility US version 1.28-1.11.
    Since then,  whenever I try to run Lenovo ThinkVantage Toolbox I receive a message: „This version of Lenovo ThinkVantage Toolbox is not licensed to run on this system“.
    I notice that the ThinkVantage Toolbox still shows the old BIOS No. 6IET49WW (1.09), while the updated BIOS is 6IET68WW (1.28).
    Any comprehensible instruction how to solve the problem for a computer layman will be much appreciated. Thanks - Jan

  • Pioneer DVR 106D does not work after firmware update

    I tried to update the firmware of my iMac with DVRFlashX. I failed. No Superdrive is showing up in the system information. DVD can't be removed even with the firmware eject function. No Pioneer drive is found. How do I get the right firmware for the Superdive via Internet to make it work again?

    Hallo und Willkommen zu den Apple Diskussionen. 
    Thanks for taking the time to let us know what happened. I assume this Firmware wasn't supplied by Apple... What updates does it achieve?

  • Cisco WS-2960S-48TS-L does not work after firmware update

    Hello.
    After purchasing the Cisco WS-2960S-48TS-L decided to do a firmware upgrade using the CISCO NETWORK ASSISTANT. Unfortunately update failed. Currently the switch when you run can not load the system image.
    Since up to now I had to deal with the other switches do not really know how to upload the correct image now. The more that you connect the switch through the console acts as to a limited extent.
    Please help

    Thank you Leo Laohoo.
    Your suggestion to usbflash0 helpful.
    It is true that I was struggling because of usbflash latest iso system also did not want to go, but I recorded version of one lower and went.
    By the way, I learned that the USB must be formatted to FAT file system.
    Again, thank you for your help.

  • HT1192 caps lock function does not work after latest update

    Hi there,
    I have a Macbook 13" Early 2011 and recently after updating my operating system to Mac OS X 10.7.4, i have found that the caps lock button isn't functioning.
    At present if i hold or press the button, it is failing to light up or function at all.
    Is there a fix for this issue, as i have read that there was an update by Apple to stop accidental pressing of this key, however not being able to access its function at all seems to be unusual.
    Your thoughts and opinions would be much appreciated,
    Thanks,
    Robsterhill101

    My Macbook Pro Early 2011 15"  (base model) did this to me last night.
    I did a PRAM Reset, the generic "Cure All Procedure" for Macs. It worked after, but I noticed that the button had to be pressed at just the right angle and with enough pressure. The light would come on and off and Caps Lock functions properly. Continued as normal.
    I put the computer to sleep by simply closing the lid, and then put myself to sleep as well.
    This morning, just before I came on here, my computer would NOT wake from sleep (a whole other issue). Would not wake up by pressing the power button. So I had to do a hard reset, hold the power button down, and press it again after...grrr I never feel good being forced to do this.
    Anyways long story a little bit shorter, I restarted my computer and low-and-behold the Cap Lock is not working again. No Bueno, Cupertino.
    No, sorry, no liquid damage on the keys, and I don't have kids, nor share my computer with anyone but myself.
    Its one of the few things that bug me about this computer. The other is the issue of the computer not being able to wake from sleep. Too often.

  • Scanner samsung scx-4300 does not work after software update v 2.3

    I'm no longer able to scan from my Samsung SCX-4300
    on macbook pro i noticed the software update has not been installed, and i can still scan without any problem
    is there a way to uninstall the software update?
    thanks.

    If  I delete the following:
    - Samsung folder in /Libraries/Printers/
    - Samsung Scanner.app in /Library/Image Capture/Devices
    Will it remove samsung driver for printer and scanner?

  • Headset does not work after latest update...

    It is very "strange" that since the latest system update on my Z3 compact my headset is not working at all. I use my all time favourite iphone 4 headset. It worked flawlessly before the update but now if I plug it in, the phone is not recognizing it at all and the walkman still plays on the phone speakers. Before the update I could listen to music, use it for making calls and so on. Since the update, nothing is working. My headset is working fibe by the way, so it is not a hardware fault. Works like a charm with other phones, and on the top of that if I use the app Soundabout the music works with the headset but the calls are still not using my headset. Do not tell me to use the sony headset which was in the package because I hate it. Has poor audio quality, falling out of my ears constantly and the cable is everything but not flexible. So it is a shame that I need to use an app to get my headset work on my new phone...

    I understand you don't want to use the bundled headset, however for troubleshooting purposes can you please test it and let us know if it works.

  • Apple TV does not work after software update

    After being prompted and loading (I think) the newest ATV update all I have on my TV screen is the iTunes icon and underneath that an icon of a USB cable icon.  When the power is plugged in the ATV status light blinks continuously.  Please not my home share is turned on.  What can be done to troubleshoot and solve this problem?

    Welcome to the Apple Community.
    If your problem persists get yourself a micro USB cable (sold separately), you can restore your Apple TV from iTunes:
        1.    Remove ALL cables from Apple TV. (if you don't you will not see Apple TV in the iTunes Source list)
        2.    Connect the micro USB cable to the Apple TV and to your computer.
        3.    Reconnect the power cable (only for Apple TV 3)
        4.    Open iTunes.
        5.    Select your Apple TV in the Devices list, and then click Restore.

  • Notebook does not start after BIOS Update crash

    Hi all,
    I just want to ask whether is a chance to reactivate my Satellite A300 after a BISO update crash without send it to the Toshiba service.
    I downloaded the new BISO and started it from the Windows menu. After a few seconds my PC crashed and everything was frozen.
    I switched off the PC.
    Now when I press the power button to start the Notebook the monitor is black and I can hear a sound brrr, brrr, brrr from the CD-Rom drive.
    Do you think it is possible to boot from a CD or something like that. Is it possible to reactivate my notebook?
    Your help would be really appreciated!
    Thanks a lot
    Best regards,
    Chotte

    Sorry but if the BIOS chip is damaged there is no much you can do about it. You must contact authorized Toshiba service provider.

  • Equium A60 does not start after BIOS update

    I have an Equium A60. After being caught with some very nasty malware and a trojan I made the disiccion to reformat the machine and reinstall the o.s..
    All went well until I updated the bios. Machine crashed and now I cannot get it to reboot. Press the power button and the machine will start for 3-4 seconds and then shuts down.
    I know this is due to the bios and want to know if there is any way that i can reset this back to it original settings?
    thanks in advance for your help

    Hi Rob.
    The model of my laptop is EA60-152 / PSA67E.
    Yes i did upgrade from the Toshiba website.
    I should have never done this it was working after the reinstall of the o.s and so i should not have tried anything else(never fix something that aint broke).
    The only place i have found for a new motherboard is Toshiba. But the price is nasty. Talk about what a fool am i.
    Never mind though i keep on thinking that there may be an answer or a scrap one that i can rob a bios chip from. Other than that a very nice paperweight me thinks..!!!!
    If i get an answer than i will post it here..

  • Satellite C660D-104 does not boot after BIOS update

    Hello,
    I installed the latest bios on my computer Satellite C660D-104 but it has not rebooted.
    Where is the place to do a reset?
    Under the ram I have no triple x or B499
    I can not find, can you help me please?
    Thanks,

    BIOS update failed this means that ROM module (where the BIOS is stored) isnt flashed properly.
    As far as I know such issue could be resolved by flashing the ROM module again using Toshiba BIOS crisis disk.
    I guess Toshiba authorized service provider own such crisis disk and could reflash the ROM
