No Option start secure on Portege Z930-138

My daughter has been using the PC above the other day when suddenly it would boot is no longer.

Now I tried to do a system restore to a backup that I did a few weeks ago, but the system reports that the computer uses the BIOS, but the backup was performed with EFI

Unfortunately, in the bios settings page, I do not have secure boot listed under the security heading.
In addition, on the system configuration page, the computer is the list of the BIOS as a mode of CSM.

Worse still, there is no possibility to change this mode because I can't select this entry.

I have now cleaned my hard drive partition and did a system restore from the recovery media that I created, but it did not always help.

This poster [has a similar problem it seems | http://forums.computers.toshiba-europe.com/forums/thread.jspa?messageID=311568񌄐]

How can I reactivate UEFI Boot/Secure boot? There must be a way.
I spent an hour on the phone with 'Toshiba Expert Care', and they suggested now I have a hardware failure.
Fortunately, I would replace the SSD, if I thought that should correct the problem, but it looks like the problem is elsewhere.

Go to the BIOS by pressing F2.
Then put the BIOS on the default settings, save the changes and power the laptop off.
Then switch on the device and access to the BIOS, once more the key F2.

According to my experience, secure boot option must be available, and you should be able to change the startup mode UEFI/CSM layout too.

However, in another thread, the user gunsh were able to resolve this problem by restoring the original state of recovery disks. This somehow automatically restored the UEFI parameters

    I changed the BIOSsetting CMS BIOS in order to boot from USB and it worked.

  • Portege Z930 cannot start with installed RAM module

    My laptop Toshiba Portege Z930-108 has stopped booting with any module of RAM installed in the support.

    If I remove RAM module, laptop computer starts and works fine, but if I install any module of RAM (4 GB 1600 original or a new 4 1600 CL9 or 1600 8 CL11) the computer cannot start.

    The screen stays black and power led flashing two green and two orange and a few seconds later, 3G indicator also on blue.

    This is the only problem I have with this computer, but it's strange.

    I updated the BIOS to the latest version and the problem is not resolved.

    I tried to reset the hardware (http://aps2.toshiba-tro.de/kb0/TSB3B03J90000R01.htm), also I tried to reset the equipment with power button 30 seconds without battery but button without success.

    Any idea on this problem of strage?

    Kind regards
    Lito.

    I guess you used bad RAM or not fully compatible modules.
    It's the only plausible explanation.

    I recommend you to order the RAM modules recommended by Toshiba that are:

    4 GB DDR3 - 1600 PA5037U-1M4G

    2 GB DDR3 - 1600 PA5037U-1M2G

    Any help please

    In this case the EPROM has to be reflashed once more using crisis disk BIOS.
    Usually this must be done by authorized maker Toshiba. But of course this will be possible only if the EPROM module has not been too bad.

    What to say: try procedure (link above) posted by Bob. In which case it will not work, ASP is your next contact point.

  • Portege Z930 - can't boot from USB

    Hello

    I recently got a brand new z930 Portege with Windows 8 is installed. I tried to install a Ubuntu Linux on the HARD drive, then:

    (1) I made a bootable USB pen drive (a liveUSB) with the OS Ubunto.
    (2) change the boot order in the BIOS of my Portege so that the USB memory is the first option.
    (3) initialized the computer with the bootable USB key connected to the USB 3.0 port.

    .. .but he initialized from the HARD disk.

    Then, I also tried directly from the start (by pressing F12 to boot) menu with the connected USB live and, when, in the start menu I chose my bootable pen drive (which has been detected) as a source of start-up.

    ... but it continues to boot from the HARD drive.

    I've proved that my USB bootable pen was trully bootable: it worked perfectly in my old 720 s HP-Compaq. And the USB 3.0 port seems to work correctly.

    I tried several times to boot from my liveUSB after some changes in the configuration of the BIOS, but was unsuccessful allwas.

    I don't really know which is the problem or what else I can do to solve it.
    Can anyone help?
    Thank you!

    Hello

    The point is that your laptop supports the new UEFI BIOS.
    This BIOS is designed for the Windows 8 operating system, and it supports certain essential requirements to win 8.
    Thus, it contains start secure option.
    This secure boot should be disabled if you want to start from another source.

  • Portege Z930: How to install Win 7 after the installation of Win 8

    Hallo!

    There are a few weeks upgraded Toshiba Portege Z930 to Windows 8. Before the upgrade made the backup of Windows 7 on USB flash and it worked. Now recovering Win8 to Win7... Recovery starts fine - choose 'out of box' recovery and get ERROR 05-0172-0001.

    How to return to Windows 7?

    Hello

    I guess that your BIOS contains the option to switch between the UEFI and BIOS of the CSM.
    It must therefore return to the CSM BIOS and must disable secure boot if it has been previously activated.

    Then you can reinstall Win 7

  • Portege Z930 - network WLan problems

    Z930 Windows 7 is 3 years old.
    I'm having problems connecting to the home network and I do not understand the clues to work towards a solution.

    Other laptops can connect to the wired network and wireless, but cant Z930, or down and will not show the home network.

    Appear networks nearby.

    Z930 can connect to the point of mobile internet access on phones, but that does not provide access to servers and network.

    Disable the Firewall Norton 360 and the protection doesn't seem to help.

    At a time and only once, I saw the message invalid network address.

    Logical, said the material is OK because can connect to the wifi phone.

    I don't know where to begin try andworkout why z930 can't seen to connect to the home network.

    > I'm having problems connecting to the home network and I do not understand the clues to work towards a solution.
    I want to be sure I understood your problem:

    You ve set up the wireless network at home (I assume you are using the WLan router, etc.) but you are not able to connect the Portege Z930 to your wireless home network.
    Is this correct?

    Since you are able to connect this notebook to internet hotspots (public WLan) I guess the wireless network for laptop s and WLan card driver are installed and are working correctly.

    Are you able to connect the laptop to the internet using LAN?

    In case this also not possible, you must reset your router and should go through the router options unique to ensure that each option has been set correctly.

    In addition I recommend you renew the IP address by typing this command using the console (to start the console type CMD in RUN)
    In the Console (black DOS window), you must type: + IPCONFIG / RENEW.
    This would renew the ip address that is assigned automatically the provided by the router ip address pool.

  • Portege Z930 - 12 H - update of the BIOS and McAfee Endpoint Encryption?

    The update to the latest BIOS (Ver.6.70) for my laptop Portege Z930 12 H comes with the warning:

    «If you use the BitLocker Windows Drive encryption, please temporarily suspend (or turn off) before BitLocker Drive Encryption updated BIOS.»

    As much I know Bitlocker isn't related to Antivirus from McAfee software and two security tools are not connected to each other. BitLocker is a tool for Microsoft Windows and McAfee is a 3rd party software preinstallation on the device.

  • Portege Z930: Loss of Fn keys after upgrade to win 8 - can't turn WiFi switch

    After several months waiting for my hour I just began my Portege Z930 - 11G for Windows 8 Pro upgrade.

    To a large extent, it went to the plan except that, after execution to display the Assistant Toshiba Upgrade I lost the Fn key and about half of the keys no longer seem to work at all.

    The only key I've ever used on a routine basis is the Fn + F8 option to activate the power switch WiFi.

    So now, I can not turn on WiFi on the computer.

    It must, surely, that there be a way to do it, but I'm not. Does anyone have a suggestion? I'm OK for now because I have a local cable system in the House, but once I get out on the road I will fight without WiFi.

    Before running the wizard upgrade of the Fn key grew up the key appear in the upper part of the screen and I want to surely I had turned on WiFi right here.

    The Fn key utility offers very little control of the Fn keys. It does not offer the possibility to do anything else than to disable five notifications screen for keyboard backlighting, power plan, touch pad and cursor overlay digital overlay.

    Any help gratefully received.

    > So now I can not turn on WiFi on the computer.
    First of all, you can enable and disable the WiFi using the function key, but you can also activate the WLan settings of Windows 8
    Key Win + C-> settings-> change PC settings-> wireless

    Now, you can use the cursor to wireless devices to enable or disable the WiFi network.

    But to get the FN button work you need to install the + Toshiba function key + Utility for win 8 and + Toshiba system driver + to win 8

  • Portege Z930 - process 'System': high CPU when on battery usage

    I have a Portege Z930.
    A process called 'System' will appear in the Task Manager when I unplug the PC from the AC.

    I would like to know why is - this high utilization of the processor (from 9% to 18%) and keep my time above 70 ° c.
    It is very annoying, not only because of the temperature that hits the PC itself, but also because of the battery, which can not go over 1 hour and 30 minutes because of this process.

    It is not a virus, already CHECKED, don't ask.
    In addition, I don't know when it started, or why, so please don't ask.

    Thanks in advance,

  • Portege Z930 - BSOD kernel data by page fault

    Recently (3 days ago) my girlfriend bought Portege Z930, and she becomes BSOD kernel data in error page, randomly (battery or AC).

    Hardware config is: Core i3 Mobile i3-3217U, DDR3 4 GB, HD Graphics 4000, SSD 128 GB
    Software: it didn't install new programs, using the trial version of office, Google chrome and windows 7 64 bit which was pre-installed. Anyone have any idea, what could be the cause of bsod? Preinstalled software from Toshiba? Hardware malfunction?

    Also because off-topic information autonomy point is up to 5 hours (wifi on, light off, bright screen keyboard: 40%)

    On this virtual path, it is not easy to say what may be the problem. In my opinion, you should make data backup and install the OS by using HARD drive recovery option.

    After that do what you will have new own preinstalled OS. Test a few days without having to install anything just to see if the error appears again.

  • Portege Z930 - display driver does not work properly

    Hello

    We have a Portege Z930 with Windows 7 64 bit in use where the Intel display driver seem to work fine.

    First problem is the slow presentation on screen - if we open a (simple JPG) photo and move the window, the frame window break during the move and showed very weird.

    Then, we have installed a U3.0 dynadock docking for the use of two external displays more. This method works even worse. To the docking station, we used the driver from the CD supplied in the delivery and connect to a USB 3.0 connector.

    On starting switching on 2 screens instead of internally for computer laptop screen does not work - and we use workaround of using an extended desktop on all 3 displays (2 external and internal display for laptop as the third).

    In Internet Explorer, it should turn off GPU Rendering and use Software Rendering rather because otherwise, we observed critical irregularities on the external screens (with 2 Windows Open the screen froze or could not display Windows Mobile). However the display isn't satisfactioning.

    We have tried 3 different versions of the recommended Driver Intel which is also offered by Toshiba to download; We loaded it is there and also 2 versions more (a more recent, one older) Intel directly.

    So, how can we get this working properly?

    Thanks in advance and best regards,
    N. Cochems

    More importantly. Make sure you have Service Pack 1 installed Win7. New laptops have problems running in win7 RTM (without service pack).

    It seems that Windows uses the standard VGA driver instead of the Intel driver. Uninstall all display drivers from Control Panel-> programs and features and then go to the Toshiba website and install the utility Intel Chipset then the Intel display driver, then go to DisplayLink.com and install the latest DisplayLink driver for the dynadock. The new software v7.xx DisplayLink driver fixes several issues found in v6.xx drivers.

    Verify that the Intel drivers are installed properly in Device Manager.

    I tried all known by me options to configure the graphic display, Intel utilities and a Windows, change text size and so on, but to no avail.
    Text is a little fuzzy looking.

    I'm 12 years old laptop user, changed a lot of it and it's my first laptop with such a poor quality screen.
    Or is it a default and I should ask replace the matrix?

    Hello

    The device supports a common 13.3 "(HD) TFT color LCD."
    The max resolution is 1366 x 768.

    So I can't find big differences between this screen and others, used in other books

    Of course 13.3 is not really a big screen I prefer notebook with a screen size of 15-17.
    The 13.3 is too small for me

    I don't know... maybe there is something wrong with the LCD display... then maybe you should ask a service provider to verify the part... but this is just my personal opinion...
