Portege Z835 - need help with BIOS update

Question: Portege Z835 - need help with BIOS update


I have a Portege Z835, with a battery problem: don't charge. The battery indicator says "3% connected and charging" but it don't charging the battery.

Some forums says that the solution is updating the Bios. I have a Bios update v.1.60 ready for install. When I try to install, we get the message "the battery power is not enough".

My power cord is always connected. If I disconnect the power cord, laptop is off.

Please, what can I do?

Preferred Solution: Portege Z835 - need help with BIOS update

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: Portege Z835 - need help with BIOS update

To be honest I don?t think it is BIOS related issue. As far as I know battery should be charged even if the notebook is OFF so why BIOS update if battery cannot be charged at all.

For me it sounds like hardware related issue.

How old is your Portege?
Is warranty still valid?

Maybe you should contact Toshiba service and ask for help or even their opinion.

I have a Z835, only 4 months old but now frozen at the 'Starting Windows' screen.

The MS Windows logo is glowing in its charming way, but I can get no further.
After that I can only do a hard shutdown using the on/off button.
The laptop worked fine for 3 months but now nothing.
I have to admit I did not create a restore disc, so to a degree have myself to blame.

It was bought in the US and I live in Mozambique where support for this is non-existent.
I can get to the setup screens using F2 during startup - but then they seem to make no difference and I'm not sure what I would do there anyway.

An IT shop tried to re-install Windows 7 from an external disc drive but it would also not go any further.

I would be very happy if anyone has an idea!

Answer:Portege Z835 frozen at startup but now nothing


For me it looks like the system cannot be booted up.
This may have different reasons: It could be possible that your HDD is faulty or there is something wrong with the preinstalled system.

So what to do?
I think you should take your recovery disk (hopefully you have created such disk in the past) and try to reinstall the system.

If this will NOT be possible because of an hardware problem? well in such case you need an additional help from an service guys?

I have just bought a new laptop and cannot connect to my wireless network. The wired one works fine. However, I need the wireless to work at home. Any help?

Answer:Trouble connecting wifi portege z835 p-330

Welcome to Seven Forums,

Does your laptop have an on/off wireless switch on the side? A combination of FN + F2 keys (depending on the manufacturer)?

Are you using a 3rd party wireless manager to connect or your Windows native WLAN Auto config?

You may try to manually connect your laptop to your SSID (wireless network name).

Hi everybody,

I resort to you because I have some doubts regarding the partitions of my notebook.
Last Wednesday I received a port?g? Z835-ST6N03 Ultrabook with a Windows 7 64 bits installed as operative system.

The problem is that I wanted to install linux and create a dual boot system, but at the moment of creating and extended partition I saw this :

[Partition image|]

According to the image the first partition is for recovering, ,
the largest one has the O.S , the third partition is to hibernate and the last one...?? (8,84gb)

How can I install a Debian linux in this system?
How can I create an extended partition when I already have the four primary partition created???

Thanks in advance!!!!!

Answer:Partitions at windows 7 in Portege Z835-ST6N03

Hello Mesti

As far as I know first 1,4GB partition belongs to OS and it is WinRE partition. This partition has nothing to do with Toshiba recovery image for OS installation. It must be 8,8GB partition.

You know what: if you want to play with partitions and your notebook in general create recovery media at first. After doing this you can do whatever you want with partitions or saved data on HDD.
After Linux installation and changing partitions you will not be able to start HDD recovery installation and this will be possible with recovery media only. It can be DVD or USB stick I think. Check users manuals and inform yourself how it works on this Prot?g? notebook.

I have a Toshiba Portege Z835 P330 ultrabook. I accidently broke the old screen and ordered a replacement from My original 14" screen was a samsung model. The one sent me was an LG. The First LG screen I received partially worked as in I could see graphics, but no backlight. I sent the screen back for an exchange, and they mailed me a replacement. Same problem: Graphics, but no backlight at all. I am perplexed. What could the issue be? I've quadruple checked the connection and restarted the laptop multiple times. It doesn't appear the video cable is damaged.

The Samsung model # of my original screen is LTN133AT25-T01
The LG Model # of the "compatible" replacement is LP133WH2

Any insight would be appreciated as im not looking forward to hashing it out with the tech anymore. Thanks

Answer:Backlight not working on replacement LED Screen Toshiba Portege z835

There are two types of laptop LCD displays: older versions that use a separate fluorescent backlight bulb with an inverter, and newer models that use a true LED backlight integral with the display screen.
Do you know which type your laptop uses? Pure LED backlit screens with have only one ribbon cable to it. CCFL screens will have a second connection.

I hope someone can help with this new problem I've encountered on my Toshiba Z835 laptop that's running on Windows 7.
Two days after installation of some Windows 7 updates, I discovered that none of the function keys on my keyboard were working (neither the FN key, nor any of the F1-F12 keys); and also the wifi function had been disabled and couldn?t be enabled/turned on. I've compiled a list of the recent update installations in case I may need to uninstall one or more items to solve the problem, but I?m hoping that some of the Windows 7 users here may have encountered the same issues and could share how they were resolved.

I should mention that I came across a thread on this forum concerning a similar situation after upgrading to Windows 10, in which several posts (including one from a Windows 7 user) reported success in turning on the disabled wifi function by running TSBWireless.exe (found here: C:\program files\TOSHIBA\Flashcards\ButtonSupport\); unhappily, however, that didn?t work in my case.

Any suggestions would be most welcome!

I have been wrestling with this device for a while now and I seem to be progressively making the situation worse.

My current issue is that I can no longer access the BIOS after changing a setting in the BIOS that related to USB emulation (or something like that). I was in the process of trying to make the device boot from a USB and pretty much twiddling with every setting to see what would work.

This one didn't. And now the device no longer responds to F2. It's like it is ignoring the keyboard. Doh!

Is there some way to roll back or re-flash the BIOS? Or another way to access it? I tried an external keyboard, to no avail.

How did I get here?

Well ... I was given this device to put back to factory condition and I could not find an obvious option that would do this, other than the Toshiba Maintenance Utility which looked hopeful. It offered to erase the partition (which at the time seemed fair enough) - BUT THAT"S all it did - so the machine just repeatedly boots, displays "Please insert system disk" and then reboots.

OK, I'm an idiot - but it does seem silly for Toshiba to offer an option that instantly bricks the machine?

Anyway, I've moved on from that problem to one that is significantly more dire. Not being able to access the BIOS means I don't have any options - unless one of you wonderful people can help me discover one.


I have since discovered that the next setting I was going to adjust - the Secure Boot setting - may have solved... Read more

Answer:Re: Portege Z30-A - Bios update 3.80-WIN using Win 7 64bit

I upgraded to 3.70 EC 1.4 as soon as I got hands on my Z30t-A and when I noticed the 3.80 was available I downloaded the zip file. None of the 15 files has started the upgrade process.

I run Windows 8.1, but the BIOS upgrade should function the same as for WIN 7.
Toshiba must have forgotten to add a setup.exe or something.

I have a Portege 3440CT with bios version 1.50.

This version does not support large HDD so I thought I'd update the BIOS. (don't know if version 1.60 does either, does anyone know?)

When I try to run the bios-update-program on win2000, it says "Initial error", anyone know what's causing this?

BIOS is downloaded from Toshibas website.

I have no floppy or CD-rom available.
Have tried the updater on win98, and also in DOS and it says "this utility not available on v86 mode!"

Is there any way to place the BIOS file on a small hard drive, and boot from that?

Ideas, anyone?

Answer:Bios update on Portege 3440CT.

Sorry CyB but I really do not understand you. If you check Toshiba support page you will find two BIOS updates. Both of them must be done using FDD. So now I am asking myself why you try to do it under running operating system. Sorry but it is really ridiculous.

Toshiba provide two different BIOS updates. One is TRAD (must be done with FDD) and WIN (can be done under running WXP or now Vista). For old notebook models there is no WIN version.

Is there any way to place the BIOS file on a small hard drive, and boot from that?

As far as I know something like this is not possible and you can check eBay and obtain FDD. You can get it for few bucks. It is really not expensive.

Also booting from this USB floppy wont work. Is this a problem related to this specific USB floppy drive (it's a NEC)? Are there any other procedures to update the BIOS?


Answer:BIOS Update on a Portege 3490

Hello Thomas

I am not sure but I assume that your unit has no USB legacy support and, as far as I know, you can do it using original Toshiba FDD. Check please your BIOS settings.

I am pretty sure that you will not be able to make BIOS update using your FDD.

Hi there,
When I look for an update to the BIOS in my M400 at the Nordics version of Toshibas homepage - here is what I find;
On the nordics toshiba website they have the 1.50 version available for download, while the US version website I can download the newer 1.60 version. As my M400 is a Danish version I am a little unsure as to if it's ok to update my BIOS to v1.60 now that the nordics toshiba website don't have that BIOS version available.

Any thoughts and views about going ahead and installing the version 1.60 on my DK-version M400 is very welcomed.


Answer:Portege M400 - BIOS update to 1.60


Please don?t compare European and US notebooks models and don?t make update mix. If you have European notebook please use just the stuff available on Toshiba Europe download page.

If you don?t have problems with your unit and if operating system runs stabile, don?t do anything. It is just my advice.

You have to start the exe file that you can find in zip-archive that you downloaded. After this the BIOS update will start.

But before you do this update, unzip all files and close all running programs. Make also sure that you are logged in as Administrator.

The istall.exe should not crash and you should not update the BIOS in safe mode!

Possibly the error code is related to corrupt windows OS or to missing some necessary Toshiba tools.
Using Win XP the Common Modules should be installed.

Hello Daniel

As far as I know it?s not necessary to install a Common Modules if you want to update the BIOS. Nevertheless normally you can find the Common Modules in ?Add and remove programs?. If you need a whole instruction ?how to make a BIOS update? you can find it on the Toshiba website.

Please go to ?Support & Downloads? then ?Knowledge Base?. There you can search for ?BIOS update?.

You can download another version of the same bios-update here : PR10U

This file contains more information about performing the update, see the readme-file
you can either do a direct update within XP or make a bootable diskette or a bootable CD

If the "direct update" within XP won't work, you will need at least an USB-fdd-drive, most of them are recognized easily by the bios ( hold F12 during start-up and choose fdd )

I was put off by the wording on the disclaimer.
It seems that in order to cut down on constant fan use the price to pay will be a hotter computer.
Is that going to affect the computer life time ?
Also, as it is a "stand alone" update, is it possible to undo the changes and revert to a previous version if necessary ?
Finally, is the increased heat on the base of the unit going to make it uncomfortable to work with as a tablet ?

Had a go at installing this, and all is fine apart from installing the Value Added Package - the main thing I want to get working is the function keys for screen brightness and connecting a TV.

I understand that upgrading the BIOS can help getting the VAP installed ( I get the ID ERR NOTINSTALLTVALZ message), I know that Toshiba are not directly supporting the A100 for Vista but is there a BIOS I can install that will work? I'm thinking there might be a similar machine that works in Vista or maybe just an A100 BIOS that will suffice?

First of all you should use and download the BIOS files only from Toshiba website.

I don?t know why you ask for the checksums or ssl certificate? the Toshiba websites are safe?
but everyone who needs the drivers or BIOS can download it?

You should only ensure that you have chosen the right notebook model and that you have downloaded the right BIOS!

But why you want to update the BIOS?
If your notebook is running troublefree then a BIOS update is not important? I follow always this advice; never change a running system.

Portege R830-138 Current BIOS 3.7

I am unable to update the BIOS to either 3.8 or the latest 3.9 version. Error: This Computer Is Not Supported.

VAP is installed and modules are working. A previous forum post suggested that it may be related to the recent Intel Management Interface firmware update which I had applied and am unable to uninstall or rollback.

Any suggestions?


Answer:Portege R830 - BIOS 3.9 Update Error


A friend of mine has updated the BIOS from 3.7 to 3.9 without any big problems.
It could be possible that you cannot update the BIOS because of the missing or disabled TVALZ services.

Go to Control panel -> Administrative Tools icon and click services.

Here you can check if the TVALZ service is available ? if its available, enable it and then try to update the BIOS.

If this will not work, you will need to recover the notebook using Recovery HDD or Recovery disk? The BIOS update should functions using the Toshiba factory settings

HI, I have Portege M700 - 116 with Vista Ultimate SP1. And I download a fresh BIOS (P005Bv160.exe) from [] version 1.60-WIN date 10/10/08. When I try to install it I have an error window said:

Unsupported product type is installed.
BIOS Package BIOS version: Ver.1.60
Current BIOS version: Ver.1.50

So my question is... WHATS WRONG?? What a product type? This BIOS update is OS independent and language independent (world wide), so i think many people with M700 will have the same problem. Is it some problems with previous version of BIOS? which I downloaded from the same site month ago. I dont understand, the BIOS installer for Windows was made to make the process easy, but it does not even work...

Answer:Portege M700 - 116 BIOS Update Error


I see you are using the Vista Ultimate.
I doubt this is an original preinstalled Vista version.

The error message: Unsupported product type is installed says that the product (software OS) which is preinstalled is not supported by BIOS. I think the error is related to the preinstalled Vista Ultimate. Possibly the BIOS cannot be updated running Vista Ultimate.

SO it would be very interesting to know if you can update the BIOS running Toshiba preinstalled OS.
Should check this!

It's a WIN 7 64-bit Machine.

Current BIOS 1.70
Current EC-Version: 1.40

For this machine, a BIOS and EC update is out there.
So I downloaded the "BIOS220_EC160.exe" update and tried to process.

The first message during the update process is: "There is need to update BIOS and EC".
When I continue with "Execute the update", I receive the error message:
"Error: Preparing to update was failed
Given image file is not compatible with this cimputer"

There are no changes in the hardware of the machine. The only problem I see is that we are using McAfee Endpoint Encryption (V6.0.2.6) which might have some influence on updating the BIOS.

But I'm not sure.
Does anybody have an ides?

Answer:Portege R700 - BIOS-Update 2.20-WIN is not working


Is BIOS update important for you?
Do you have problems with notebook?

I?ve got three years old notebook and BIOS has not been updated?

However, as far as I know the VAP (value added package) needs to be up to date to get BIOS updated?. Also the firewalls and other security and antivirus software preinstalled on the system should be disabled before trying to update the BIOS.

Good day, I have two questions about Portege 3410.

The first one: I cannot update BIOS (there is 1.50 in use, I want to update to 1.60). The instruction does not work: I connect Teac USB-drive on USB-port, switch USB-FDD emulation to Enable, switch notebook On with F12 pressed, the message "Ready to update BIOS..." appears, I presed key, but nothing happend. What's wrong?

The second one: I cannot install Windows XP on to notebook (it does not boot neither FDD-USB, nor External DVD-USB).
How can I install Windows?

Thank you.

Answer:Portege 3410 - How to update BIOS and install XP?


Just one question: Why do you want to update the BIOS? Is it really necessary?
I ask this because this update is always a little bit risky and you could damage the ROM module.
Anyway, have you tried to load default settings in BIOS before you start the update and install XP?

You can install XP without CD. Therefore you must copy the i386 folder on the HDD from another computer and some booting files for HDD? I think you should search a little bit with Google to find workaround for this. You should find enough! ;)

I want to update the bios of my Portege R500 to the 1.6 version. It's a windows-update BIOS and when I launch it under Windows 7, I get the message:
[Error] BIOS Update is not supported OS. Unsupported OS or service pack is installed.

I have to reinstall XP in order to update the Bios? File name is P0058v160.exe. Does anyone know if BIOS update works in Virtualisation mode? I would install Sunbox VM, install XP and run the BIOS update. But will it work?

Does anyone has an idea?



Answer:Re: Portege R500 - How to update BIOS on Windows 7?

Hi Roro,

Yes you have to install Windows XP to update the BIOS but my question is: Is this update necessary or just for fun? BIOS update is always a little bit risky and should only be done to solve problems. If your computer runs properly I wouldn?t make this update.

I don?t know if this update is possible on Virtual XP but I wouldn?t try it. If the update fails you need a new ROM module or mainboard. I think the BIOS update isn?t designed for Virtualization mode?

Is somebody out there have the proper procedure to update the bios of a Portege 7200CT without the docking station.

Toshiba has posted a procedure in its bulletin but it does not explain how to do the update without the docking station. As everybody knows that the Portege 7200CT has its floppy drive on the docking station and if we follow the Toshiba updating procedure we have to undock the laptop, so how can we proceed with the update if the update software calls for a floppy drive that is on default to drive A:

I recently picked up a Portege M200 and installed (via PXE - network install) Windows 7 on it. I would like to upgrade the BIOS as it's still at the original BIOS (1.1). I downloaded and extracted the pkg and tried to install via Windows but it says my OS isn't supported. I don't have an external CD drive or FDD - how can I update the BIOS? I tried to put it on a USB drive but there doesn't seem to be an option to boot from USB.

And I see it doesn't recognize the video card either - just uses Standard VGA Graphics Adapter which seems to work fine...

how can I update my BIOS when using Ubuntu Linux?

The reason why I'd like to update my BIOS is that on the one hand Ubuntu
writes an error message during boot-up and recommends to upgrade it and on
the other hand I'm afraid that there is maybe a temperature problem, at least the
notebook becomes slower after working for a while.

The notebook operating temperature usually is between 45-64 degrees.
The fan turns on at 62 degrees and turns off at 52 degrees.

Temperature seems to be pretty normal I would say but I think its not normal that the
notebook becomes slower when operating above 50 degrees.

I already opened it, it seems to be all right with the cooling unit, no dirt e.g...

Answer:Portege 2010 BIOS update / operating temperature

Dear Julio

I presume you know that Linux is not supported OS and designed BIOS update is created to be performed in running Windows OS. This nice Portege is known to me and I know very well that it is not the fastest notebook and it is designed for business purposes like working with Office, e-mail communication and every other everyday activity.

Because of that answer to your latest question can be: yes you persuade yourself.

please help me with my portege M400, I installed a new localized version of Windows XP , then I started to download the drivers from Toshiba website, and the first thing I did is installing the new BIOS update. I don't know which version was it. Then it asked me for restart, after I did the restart the device doesn't boot anymore, and I can see only a blinking orange LED, :(

Please how can I reset my old BIOS? Is it the end of my Toshiba?
I'm now in a forign country and there are noToshiba service center near to me

Please is there anyway to help me

Answer:Portege M400 - doesn't start after a BIOS update


I think in this case you must go to an ASP. I don?t see another solution for this problem because I think the ROM module must be reflashed or the completely mainboard must be replaced.

On the Toshiba website you can search for the nearest ASP: => Support & Downloads => Find an authorized service provider

And if you don?t find an ASP in your country just contact an ASP in another country. I?m sure that they will try to help you.

I have an old M800-106 (model PPM81E-00K00JEN). It is good condition and has been reliable, and I don't want to scrap it. Unfortunately the Windows based BIOS update from Toshiba's website froze during it's operation, and now the laptop won't restart.

The cost of sending it to an authorised service provider to repair is significantly more than the cost of replacing the laptop, and I'd be charged even if they didn't fix it. I'm not saying it's expensive - if someone has skills and does some work they should be paid for it, but it's not what I want to spend money on for this laptop.

Environmentally it'd bad to just chuck the laptop away/take to the recycling centre.

I could strip the motherboard out and send that away to have the BIOS chip replaced or reprogrammed, but that would be time consuming and risk me damaging it.

I would like to attempt to flash the BIOS chip, using the crisis Phoenix tools that are available online, but so far haven't found a *.rom or *.wph file to use.

Where can I get the BIOS file - to be honest any version that suits this laptop would do, it doesn't need to be the most recent one.

Any helpful advice gratefully received.

I'm having problems with my R500, so thought I would update the BIOS.

This contains the file P0058v160.exe

Starting that process leads to:

Do these BIOSes have to be installed incrementally? My r500 is an early one and currently running v1.00.


Answer:Re: Portege R500 - Bios update installer crashes


If you want to update the BIOS then you have to download the BIOS package and have to unzip it firstly.
Then execute the exe stored in the folder.

I?m not sure why the error message appears but please ensure that the Common Modules are installed on your system.

If the error will still persists then this could be a problem with the installed Windows OS and not with the BIOS software.

Hello Forum,

i have exactly the same problem as described here, 2 years ago:

I need to update my BIOS, but i cant because the BIOS Updater tells me that Intel-TXT is enabled.
Unfortunatelly i cant disable it in my bios. Its just not selectable. The "cursor" just jumps over it.
I can only "Hide" it which doesnt help.
I have the same for the VT-d and VT-x setting in the BIOS. This is not selectable or changeable as well.

TPM isnt enabled though...
I installed the infineon suite and it tells me that i need to enable TPM in bios to use it. :-(

I have an very old Bios Version 3.1 and i read in the changelog that in V3.4 and 3.5 there were many TPM related changes....

Back then, a user named Paolo30 uploaded a file to which fixed this.
Unfortunatelly this file was deleted on

can someone please provide that file (or a later bios update) which fixes this?
Thanks in advance.

That?s strange.
Did you change something on you installed Vista?

In different cases the BIOS cannot be updated because some essential tools like common modules for Win XP has not been installed.
If you are using vista you don?t need Common Modules but I recommend reinstalling VAP.
Then you should try to run BIOS update again.

Otherwise use the recovery disk and set the notebook back to factory settings.
After the notebook has been set to the same state like at the first day of purchase, you could run BIOS update.

Usually the BIOS support the booting from CD/DVD drive, HDD, LAN and USB FDD.
It should be possible to boot from a bootable diskette using an USB FDD drive.

Anyway, the system32 fault has nothing to do with BIOS and I don?t understand why you started the BIOS update.

The Portege 3500 does not support an internal drive and therefore if you want to install the OS you have to use a compatible external PC-card drive.
I assume you use such drive for booting.

If some error messages appear during the installation procedure, you should firstly format the whole HDD and delete all partitions and then try again to boot from the recovery CD!

The BIOS update should not take a long time.

In your case is it possible that something went wrong during the flashing process and the ROM module has not been flashed properly.

The BIOS ROM must be flashed again using an crisis procedure and this can be done only by an ASP technician.

We have a Toshiba Z835-P330 (PT224U-001001) laptop with Windows 7 x64 that got its Intel Centrino Wireless-N 1000 (112BNHMW) wireless card replaced with an Intel Centrino Advanced-N 6235 (6235ANHMW) because of wireless connectivity issues (getting dropped from wireless anywhere from 3 to 6 times a day --> required to reboot to get reconnected). We have dozens of other laptops that are similar to this model -- same chassis -- but run Windows 8 and have an Intel Centrino Wireless-N 2230 that also gives them the same exact wireless connectivity problems. Our solution is to replace the wireless cards with something else.

So far it has been working great, except for this Z835 Windows 7 user we have. I have the latest Intel software for the card downloaded and extracted on the laptop in the Downloads folder. I need to run the installation and after installation it works fine... for a few days... then the laptop somehow magically forgets the drivers and the user has to re-run the installation to get wireless working.

Any ideas? I plan on buying another DIFFERENT wireless card than the Intel 6235, and if the problem continues I will suggest either an upgrade to Windows 8 or laptop replacement altogether.

PS. Toshiba has been full of suck. All the ultra thin silver-colored laptops we have received from them have wireless connectivity problems, dropping users from wireless connectivity 3-6 times a day with no way to reconnect but by doing a full restart. We have trie... Read more

In preparation for Win 10 key I updated the BIOS on an E520 using the Lenovo Service Bridge.  Os is Win 7 64-bit.  LSB showed old BIOS was backed up. Old bios   LENOVO 8HET30WW(1.12) New bios LENOVO 8HET44WW(1.26) Now bootup and windows start up are painfully slow.  Further there is a black screen in the middle of the wake up process. How can I undo the BIOS update to revert back to Old bios   LENOVO 8HET30WW(1.12)? Or can anything be tweaked to improve the bootup time?

Answer:E520 slows/black screen after BIOS update. Can I undo BIOS update?

Unfortunately Toshiba Europe doesn?t offer list with description what is new in this BIOS update.

Which key do I use enter the BIOS? F12 is to choose which boot drive but I can't get into BIOS settings.


Answer:Re: Portege - Which key I need to enter the BIOS?


It would be very useful if you also post what notebook model you have ;)

Anyway, if you can go into boot menu pressing F12 you should be able to access BIOS if you press *F2*.
Check this!

Did toshiba change the fan-behaviour? The fan is not loud/annoying, but it could kick in a little bit later.

Running Ubuntu Linux on the M400 and it seems almost all BIOS versions prior 3.60 are broken because there are APIC quirk errors on the CPU. Maybe Microsoft could work around the broken APIC tables for a while but with Linux things are a bit cumbersome. Microsoft asked Toshiba for a BIOS update to deal with these issues and starting from 3.50 it seems to be fixed.

see here

Even in Linux no more APIC errors are seen. :-) But after updating to 3.60 BIOS the boot screen stays active and is preventing me to select an option for a multi boot entry (grub). When the OS is already starting the boot screen turns white at first and then gives finally control to the OS. Are others seeing this as well?

I am able to select something in my boot menu but it's more guessing because the boot screen is still on top. Very annoying this :-(

Another issue I have is that sometimes the system freezes for a couple of seconds and then goes on, nothing to be seen in logs when using Ubuntu or WXP tablet. So could be a bug in BIOS once again. Again looking for confirmation, are other experiencing this as well.

Did reflash 3.60 a couple of times but seeing this behaviour over and over again.

Although there seems to be some fan control in 3.60. It doesn't fire like a DC9 but still not as silent as the 1.80W or 2.10N BIOS versions were. Love to see these fan noise changes incorporated in 3.60 and later?

Answer:Portege M400 and 3.60 BIOS

Hi Robert

I know you will hate me but the fact is that Portege M400 has sticker near the keyboard and there is written something like ?Designed for Microsoft ??. With short words: Linux OS is not supported.

If you need some help with Linux on Toshiba notebooks please check

Issue about freezing is very strange and if you want to check it properly install recovery image without any additional software. In this case you will have ?factory settings? and clean preinstalled OS. If you will notice some exceptional issues you should contact authorized service partner and clarify this.

Good luck!

Hello everyone,

I upgraded the BIOS on my Z30-B-119 laptop, and it is much worst than the original BIOS so I would like to downgrade it.
There was no way to save the original BIOS when updating and the previous BIOS is not available on the website.

Do anyone have the original BIOS and knows how to extract it?

Or maybe someone knows how to contact Toshiba technical team directly? (Seeing what they implemented in new BIOS, I have no hopes they read this forum or care about user opinions.)

If you wonder why I want to downgrade and what is wrong with it, see below for explanation.

I was convinced that the new BIOS would fix the problem with the fan, which switched on way too early, but it turned out they made it much worst! Now the fan switches on at 42?. Before it was 50?, which was already a stupid choice of Toshiba engineers, providing that the temperature rating of this CPU is 105? so they could keep the laptop quiet at least up to 60?, especially that many people complain about the fan in this model. Instead, Toshiba did the opposite and lowered the temperature even more.

Seeing how senseless choices their engineers make, I will never buy another Toshiba and will not recommend anyone buying their products. But since I already made the mistake an bought a Toshiba laptop, I hope I will be able to downgrade the BIOS or contact them to ask for an update.

Let me know if you know how to do it.

Hello to the BleepingComputer community,First of all I'm sorry I haven't finished some of the steps from the Preparation Guide. It's because these steps require a reboot (e.g. Step 6: Disable your CD Emulation Software - DeFogger will ask me to reboot the machine), and I have a bad feeling about the question if it is safe to reboot in my situation: I'm not sure if I have a type of malware which is ready to infect the BIOS - if it is so, then it could infect it much easier during the reboot process.- If there is a good way to find out what is the problem (and fix the BIOS threat part if it really is present) without rebooting / shutting down this PC, or at least without booting from this hard drive (which I feel is probably infected), then please tell me what should I do.- If you know a place / forum where I can get a specialized help for this (seemingly BIOS-malware related) situation, please tell me where I could go.- If there is no way to move forward, I'll go ahead and risk the reboot, and follow the other steps (steps 6 to 10) in the Preparation Guide, no problem.I kindly ask you to please read below the details of the problem as it occured to me, and the things I have tried so far.The PC is AMD Athlon 64 X2 Dual Core BE-2350 2.1GHz, Motherboard Biostar TA690G AM2 (with AWARD BIOS), 4GB RAM, 200GB SATA HDD, and an ASUS EAH4870 card added a few years ago.It's with WinXP SP3, AVG Free 2012, (standard) Windows Firewall, and it's behind a router.I ...

I've bought the Z930. Two days ago I got a TEMPRO alert about a BIOS update.
I downloaded the zip file of new BIOS and started the installation.

Then I got a message like this:

BIOS Version: Current Ver.2.30 -> Update Ver.2.20
EC Version: Current Ver.1.20 -> Update Ver.1.20
BIOS should be updated.

Then I cancelled the installation.

Why did I get an alert about a previous version? Should be done the update?

Answer:Portege Z930 - BIOS downgrade from v2.30 to v2.20

My advice is to ignore this update. You have new piece of hardware so in next days test functionality and I really hope you will be happy with it. if everything works well and there is no some serious issue with it don?t change anything.

Since few months I?m thinking to buy it too because I want to have such small portable ultrabook so please be so nice and post short review if you will find some time for it.

I would like to read what do you think about it.

HI all, I've got a Toshiba *Z930-15X*, and I can't access the BIOS at all.

You have to perform full Windows 8 shut down!

Can someone help me and send me via e-mail ? [email protected]

thanks a lot.

Unfortunately, Toshiba European driver page provides just the newest BISO versions.
But I found also older BIOS versions on the Toshiba US driver page.
[Portege R700-S1320| rpn=PT311U&modelFilter=R700-S1320&selCategory=2756709&selFamily=1073768662]

But it?s for Portege R700-S1320 and the series PT310U / PT311U / PT314U
So possibly it?s the same BIOS which is designed for Portege R700 PT311E (E means European U means USA)

i do not have a floppy drive on my machine, only usb ports and a sd card slot. How can i upgrade the bios?


Answer:Portege 4000 bios upgrade

The easiest way is to create a dos boot cd-rom. There are several descriptions on the web. Google for it.
Add the extracted Toshiba bios files, ec29nobb.bin, chgbiosa.exe and chgfirma.exe to the CD-rom.

At first boot from the cd and run 'chgfirma ec29nobb.bin'.
Now the ECKBC-Firmware is written (don't power off during flash!!!)
Than boot again from cd and run 'chgbiosa'.
This flashes the Bios.
Both flash are necessary!

Here is how to extract the Toshiba bios file.
At first you have to extract the R211VOL2.exe file. Easiest way to do so is to use 'universal extractor' -- google for it.
After this you will get the file R211VOL2.IMA. This is a floppy image file.
You can extract the single files in the archiv using winimage (trial version should work).

Good luck!

Hi All,

I have a Toshiba Portege R830, running 32-bit Windows 7 (SP1) enterprise (for work).
I also boot into Linux Mint 14 64-bit, which I have installed on a portable USB HDD (outside work).

I recently bought a USB 3 HDD, but when I connect it to the USB 3 port on my R830, it only gives me USB 2 speeds (25 MB/s).

I checked with some diagnostic utilities (usbdeview, etc), which say that the drive is connected in USB 2.1 mode.

The drive reports itself as being USB 3, the cable is USB 3 (SuperSpeed), and the port I'm using on the R830 is 3.

I experience the same, whether I boot into windows or linux.

I updated all drivers on both OSs, to no avail.

next i tried to update the BIOS, but I keep getting the following error:
"An error occurred while preparing the update environment.
You have not given permission to execute the update."

For the record, this is the BIOS I'm going from, & to.
BIOS Version : Current Ver.2.80 --> Updated Ver.4.10
EC Version : Current Ver.1.10 --> Updated Ver.1.60

Does anyone know why I would not be getting USB 3 speeds (which, for my drive, are expected to be around 40 to 50 MB/s), or why all diagnostics are saying USB 2?

Does anyone know how to overcome the BIOS update issue?
(I've tried safe mode, disabling AV, disabling NX)


Answer:Portege R830 - USB 3 & BIOS updates

Is this USB driver installed?

Please try to install it and check USB speed again.
