Now, I think that its in the middle of the brightness settings and I can not change it...

and another problem: the network connection is not working.
I can't connect to my Wifi, but my other devices can... and on the audio... they are all disabled... can not do something. but my solution to this is refreshing my laptop at the restored but point im doin it all the time tired when I met this problem coz I need a lot of software installed again...

Please someone here already encountered this problem and have a solution with the exception of updating my laptop? :(

Hi Symba,

I m wondering how you use the function keys.
As far as I know you can use the function keys in the traditional two keys FN key combinations, or you can press only F (F1 - F9).
This option can be changed in the BIOS (-> Advanced tab of the system configuration) or in the HWSetup utility.

To solve the problems of WiFi:
I recommend you update the WLan driver first.
Then, you can add a new WLan profile. This can be done in the Panel (switch to the display of the icon)-> Network & Sharing Center. On the left, you will see that the option called manage wireless networks. Until it clicks. Now, you could add and configure the new Wlan

Regarding sound problems:
Make sure that its not muted. Additional go to control panel-> sound and ensure that the speakers are turned on in the reading tab.

    Hi Paul

    First remove the main battery from the laptop does not reset the BIOS!
    To me, it sounds really strange that you should always just the battery to start the device.

    Also the sound you mentioned in your post seems to come from a piece of internal material (cooling event, drive HARD or maybe CPU?) and not speakers.

    I guess that there is a serious hardware problem and I don t think you will be able to solve this problem without the assistance of an authorized technician.

    button / (divide), does not work in the formula (instead of printing +), what to do?

    Look VERY carefully at what you see as + the divide symbol appears as a Chief and a threshold which, for some people, looks like a +. If you don't see the symbol try enter the formula and see if it DOES not give you the correct result.

    Hello

    > This problem start after a storm in my area some time ago.

    Because other devices don't work properly and because procedure didn t get it back help you solve this problem, I think that the problem is related to the hardware malfunction possibly that the motherboard was hit by lightning, which would explain the problems

    I think you should ask the maintainer authorized Toshiba in your country to check the motherboard.

    But in my opinion, that the warranty does not cover the issues of environmental impact maybe your household insurance could help you

    You are using a newer version of El Capitan that the updater contains and so cannot install it.

  • MBR - Volume does not contain a file system recognized - after bootrec options

    I was unable to install the Vista SP2 (as it appeared later, because of a Grub boot loader installed by Linux). I tried to reconfigure the bootloader and the partitions (which allows to boot directly into Windows), but after several bootloader configurations (load different partitions as well as MBR) and some partition resizing (resize incl. NTFS partition). Windows unbootable.

    I tried Windows Rescue Disk:

    Bootrec /fixmbr succeeded

    Bootrec /fixboot did not work until I made the /scanos (including iedentified, after having disassembled the NTFS Linux partition and putting the flag of boot loader in the MBR and the default option of grub in Windows, there are 1 installation of Windows in C:\windows).

    If I then repeated bootrec /fixboot he gave the message that the volume does not contain a recognized file system.

    I also did bootrec /rebuildBCD (after renamed it bcd), ultimately without success.

    In total, the situation of 'better' I reached was either a Windows startup with a cursor flashing something happens (apparently find the partition but not any which boot file or OS); or the spare arriving to determine that there is a partition of Windows Vista, but (following the first option to simply repair the system) 'no errors detected. " The second option here, "Restore to a previous point" refers to that there is no previous such restore point.

    It took me about 24 hours now to finally get SP2 installed, but obviously with only murkier.

    Hi Willem W,.

    I suggest trying the (step 1 in the link) Startup Repair and then manually rebuild the BCD (Boot Configuration data) using Bcdedit.exe (step 3) in the article below and check if this solves the problem

    Error message when you start Windows Vista: "the Windows Boot Configuration data file is missing required information".

  • USB flash drive receives an error "volume does not contain a recognized file system" in Windows 7

    I plugged my USB on a windows 7. He always invites me to analyze and correct or cancel. I cancelled each time, but I got bored with it popping up each time, so I said to investigate and fix.  A loading screen came so I waited patiently. After that it asks me to format my USB flash drive. I can't format it but because I have files from work to home and all my other personal files out there. So I cancelled the format, but every time that I plug it into my computer it asks t format. I even plugged in on a computer running windows XP and wanted to get in shape. When I try to run it without formatting as it is said, "E:\ is not accessible. The volume does not contain a recognized file system. Please make sure that all required file system drivers are loaded and that the volume is not corrupted. "My question is... what we Windows 7 to my USB and how can I recover my data?

    This is common with USB drives used on different operating systems. It happens alwaysto me when I use my drive to work (which is managed since my MacBook Pro) on Vista and Windows 7 client computers. Like you, I learned the hard way you must cancel the digitization of Vista/Win7. The only thing to do at this stage is to connect the player to a computer that can read the files OR use the software of data recovery on it to get the files. I believe that Recuva can do it for free. Format the Flash DRIVE, then start again. Either way, you don't want to use a USB key as a single backup of important files because - as you have unfortunately discovered - stuff happens.
