BIOS 1.40 release

Reader Julien Lanza reports that BIOS version 1.40 has been released.

There has also been a 1.30 release, which possibly was not made available on Toshiba’s website until 1.40 was released.

The download and changelog are at

It ships as a Windows EXE file, which is in fact a ZIP archive extractable with ‘unzip’.  Inside it are an EXE which can be run from inside Windows to update the BIOS, and an ISO. I successfully burned the ISO to a CD and booted it from a USB CD-ROM drive (in UEFI mode) to run the update.

As Julien notes, a CSM (legacy BIOS) support mode is now offered. Reports from anyone who has tested this would be appreciated 🙂 If anyone proves it working (for installation and subsequent booting of the installed system) we should update the page.

With the 1.40 BIOS, I still need “acpi_backlight=vendor” to have working backlight control in X, and I still need “i8042.reset i8042.nomux=1” to have a reliably working keyboard after resume-from-suspend.

The internal ethernet (r8169) is still broken after a suspend/resume cycle.

There are microcode updates, so further investigation might find differences in power consumption, sleep behaviour, etc.

Thanks Julien!

  2. SO, mentalnirex,

    Does the fan control work?

    To upgrade BIOS firmware to 1.40, can i burn the os2014198a_140.iso image into a usb 3.0 stick and use the left port 3.0 to install?, if not, tell me how to upgrade. What about running from windows?

    If i install mint and disable suspend when iddle and disable suspend from button, and suspend from lid close, will i have problems related to cpu power…etc?

  3. Hi anonymous person with throw-away email account,

    What fan control? What fans?

    I’m not sure what you mean by “burn” the image to a USB stick. You could try copying it to the USB stick with dd, but that didn’t work for me. I wrote it to a physical CD.

    You’ll have to explain what you mean by “problems related to CPU power…etc”.

    • Hello from Spain,

      sorry for using this account i found at bugmenot, as i dont use wordpress, twitter, faceb..

      You said: “Fan control (no fans detected by lm-sensors, no fan heard operating)”.
      That’s why i want to know if cpu fan works ok with v1.40 of BIOS.
      I have heard of hardinfo, and the is a user that says he can’t see fan working .

      About CPU, i mean:

      there you said: “resulting in possible heat damage and unexpected flat battery”.

      Another question is.. if you disable sleep on lid close.., why do you need to disable wake up?.

      I just don’t know how to use this step:

      echo ” LID” > /proc/acpi/wakeup (note the space between the first ” and the word LID)
      Once you’re happy that it works, add that line to /etc/rc.local.

      Which line do i add to /etc/rc.local ? and how?

      Thank you for your replies!

      • Hi,

        The NB10 does not have any fans.

        I don’t have any problems with unexpected suspend or resume.

        If you’re not comfortable with editing rc.local yourself, I am not sure that it is a good idea. But if you did want to, the line I have in /etc/rc.local (above the final “exit 0″) is

        echo ” LID” > /proc/acpi/wakeup
