The fn keys that control the brightness work as long as the laptop does not get suspended. If the laptop is suspended then upon resuming the fn keys no longer work. The fix is as follows:


to /etc/default/grub under GRUB_CMDLINE_LINUX_DEFAULT, then run update-grub. After rebooting, this will remove the acpi_video0 from /sys/class/backlight/ leaving you just with intel_backlight and toshiba. Upon resuming with these settings the screen will be completely black with no means of making it brighter. To fix this one needs to create and add the following to /etc/pm/sleep.d/restore_brightness:

case "$1" in
      #do nothing
      echo 7 > /sys/class/backlight/toshiba/brightness
      exit 1
exit 0

Don't forget to chmod +x the script. You should now have a trouble free laptop :)


acpi_osi=Linux acpi_backlight=vendor pcie_aspm=force i915.i915_enable_rc6=1 i915.lvds_downclock=1

to /etc/default/grub under GRUB_CMDLINE_LINUX_DEFAULT will make a significant increase for your laptop's battery life. I also recommend applying SSD optimizations to save your SSD and more battery life.

Fan noise problem (windows problem too) solved updating BIOS to 1.60. You need a partition with Windows to aply the update.
In order to update the bios on a clean install of windows 7 (non toshiba image) you will need to install the following 2 drivers from the support page:

  • chip set utility
  • value added package

Thanks to redmongoose


All my needs covered! A great machine with a good linux support.
BlueTooth needs investigations to work. Linux recognized it, but no more (Please update if anyone finds a solution or can prove otherwise).

I don't know if this thread is still alive but I have been using thePortege_Z830-10f for a few years now (since launch) and have been extremely satisfied with the Fedora distro. The only problem I have had recently is with the KDE Plasma desktop which seems to over-run the CPU somewhat, so I am using xfce for home use and i3 whilst travelling (giving me over 5 hrs of battery time).

I never did find a right solution for the standby issue so I've just learned to live with it!

kostas, 2017/04/27 02:26

Hello everyone,
I am not sure if some of you are still using this laptop but I recently got a second hand one for my lady and I am trying to install linux onto it.
I installed the last Debian 8.7 and I manage to overcome the problem of the backlight after suspend with “acpi_backlight=vendor” kernel option in grub and also by creating a file 20-intel.conf in /usr/share/X11/xorg.conf.d with

Section “Device”

      Identifier  "card0"
      Driver      "intel"
      Option      "Backlight"  "intel_backlight"


I also tryed many other solutions I found on-line but this one seems to be the only that work with Debian.
Since then, the backlight works but Debian completely freezes very often without any particular reason.

Another thing I noticed is sometimes while Debian boots the following error comes up:
[drm:intel_enable_lvds] *ERROR* timed out waiting for panel to power on
Do you have any idea what this might be and how to resolve it? google doesn't really give much info about it.

If anyone still uses the same laptop, can you please tell me what distro do you use and how you solved the backlight problem or any other problem you might had?


Monika, 2017/04/27 05:54

Hi Kostas,

I am still using my Toshiba, yes. Just last week I installed UbuntuStudio, the LTS, i.e. 16.04. This one worked out of the box for me (I usually don't use Bluetooth, but even that seems to work, would be worth a try). Wireless run already throughout installation; I don't know about the buttons for mousepad and the other ones wich can be a hassle, I don't use them.
Fan is way calmer than before and with windows, they seem to have worked on it.


someone, 2016/05/17 14:59

For me it just works with kernel 4.5, except the illumination short-cut. You can toggle it manually, by writing “2”(on),“6”(timer) or “18”(off) to


Javi, 2014/02/18 10:47

Ey, I think I'm gonna switch to Ubuntu. However, which version will you install?

PC (Intel x86) desktop CD
For almost all PCs. This includes most machines with Intel/AMD/etc type processors and almost all computers that run Microsoft Windows, as well as newer Apple Macintosh systems based on Intel processors. Choose this if you are at all unsure.

64-bit PC (AMD64) desktop CD
Choose this to take full advantage of computers based on the AMD64 or EM64T architecture (e.g., Athlon64, Opteron, EM64T Xeon, Core 2). If you have a non-64-bit processor made by AMD, or if you need full support for 32-bit code, use the Intel x86 images instead.

Thank you

Klaus, 2013/04/07 14:32

Hi, in the recent ubuntu 13.04 Beta 2, the mentioned fix for the backlight did not work anymore, so I added an udev script as mentioned here:


DEVPATH==“*/toshiba”, SUBSYSTEM==“backlight”, ACTION==“change”, RUN+=”/etc/udev/rules.d/”

/etc/udev/rules.d/ (must be executable):

acpi_max=$(cat /sys/class/backlight/toshiba/max_brightness)
acpi_curr=$(cat /sys/class/backlight/toshiba/brightness)
intel_max=$(cat /sys/class/backlight/intel_backlight/max_brightness)
echo $intel_curr > /sys/class/backlight/intel_backlight/brightness

1) $intel_max*$acpi_curr/$acpi_max
Wolfgang, 2013/05/24 13:47


is there any other step necessary to make this work? I tried to use the script but I keep failing miserably.

Running the script as root from command line works fine. But after opening the lid and trying to press the brightness keys it does not seem to work. Popup notification is correct but the value simply is not set.


Wolfgang, 2013/06/07 17:00

Found the problem:

/etc/udev/rules.d/ needs this as a first line:


Hope this helps other users like myself ;)

For people using vanilla kernels, the workarounds have no effect since Linus' tree hasn't incorporated any of the patches to toshiba_acpi.c. I took the patch from:

and modified it so it works with kernel 3.7.6; it will probably work with some older kernels. I'm using Gentoo, with vanilla kernel as stated, and with this patch and acpi_osi=Linux acpi_backlight=vendor in my kernel command line I can change the brightness after suspending my Toshiba Portègè Z835 laptop.

Hi all,

first of all, please excuse my sloppy English.

I installed Ubuntu 12.10 64bit on a Toshiba Z930-Q12 Satellite in dual boot with Windows 8.

Everything ok, but I have a weird issue with at boot time!

At every restart of the machine GRUB one time starts and one time it doesn't. When GRUB doesn't start, Windows 8 start normally.

This is my partition table

/dev/sda1 nffs - System 450MB hidden,diag
/dev/sda2 fat32 /boot/efi - 260MB boot
/dev/sda3 ntfs - - 128MB msftres
/dev/sda4 ntfs - - 50GB -
/dev/sda5 ext4 / - 10GB -
/dev/sda6 swap - - 4GB -
/dev/sda7 ext4 /home - 55GB -

What can I do, delete /dev/sda1 ? delete /dev/sda1 and partition it as /boot ?

Any suggestion will be appreciated,


NB: One positive thing: I did a backup on USB (Toshiba Recovery). I tried it once and it works fine! :)

pankrazius, 2012/12/20 16:03

can anybody tell me if z930 uses the same chipset as z830?
i ask because i want to know if adding

i915.i915_enable_rc6=1 i915.lvds_downclock=1

to GRUB_CMDLINE_LINUX_DEFAULT works with the same effect on the z930 too

loikun, 2012/08/06 14:36

Someone has test Linux on the new model z930/935 ?

Roy, 2012/08/08 20:47

Got one of those today, Satellite Z930. Running Mint13, no problems so far except for the things described in the topic.
Solutions worked flawlessly, thanks for the post. Did not test the Bluetooth yet.
Only thing to figure out now is how I can change the keyboard backlight settings. Fn+Z does respond on screen with the appropriate icon but has no effect on the lights itself though.

"Super" Nathan Weber, 2012/08/29 06:32

I just did, Working great!

John, 2012/08/03 21:04

thx for the wonderful infos here. Just wondering:

The script for restoring brightness control works fine with standby, but doesn't with hibernate (suspend to disk). Is it possible to extend the functionality?

Patrick, 2012/08/01 09:44

When there's an SD card in, the computer is not able to go to sleep under Linux Mint Debian Edition. To solve this, I created /etc/pm/config.d/00sleep_module with the following text in it:


Again, don't forget to make executable:

sudo chmod 755 /etc/pm/config.d/00sleep_module

Akil Mahimwala, 2012/07/29 09:36

I have a Portege R830-10R running Ubuntu 11.10 The backlight solution worked just fine for me. Thank you very much for posting.


John, 2012/07/25 17:15

… alright alright, found the reason:

I took your “under GRUB_CMDLINE_LINUX_DEFAULT” all too literally by putting the inserts in the line _under_ the one you mentioned instead of between the ””.

BTW: Since BIOS is updated to V1.60, the fan is no problem anymore.

best regards

John, 2012/07/25 16:01

Hi, I like the device very much but the backlight fix doesn't work for me for some reason (Lubuntu Precise). I added …


… at the relevant point in /etc/default/grub but the file acpi_video0 is still present in /sys/class/backlight/ after update-grub and reboot. I don't know the reason and cannot delete or move it, not even as root.

Second problem is that update-grub says “i915.lvds_downclock=1: not found”, same with the other i915 command. Thus I commented both out in order to have update-grub go through, but still that is strange. Any ideas?

Here's my /etc/default/grub section:

GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
# i915.i915_enable_rc6=1
# i915.lvds_downclock=1

joch, 2012/06/27 11:33

Blutooth now works with latest kernel update.

Bogdan, 2012/05/30 15:44

For those interested to update the bios from linux, here is the recipe:

I tried it and it works fine.

However, there are some mistakes and I modified for my distro.

For example syslinux stuff is found in/user/share/syslinux and not in /usr/lib/syslinux

   sudo cp t224v160_120.iso /mnt 

must be changed to

   sudo cp t224v160_120.iso /mnt/bios



Monika, 2012/05/30 21:03

puh, I have no idea about that hard blocked thing. But I just noticed that above they write for wireless “Atheros” and by now I'm pretty shure, that mine is no atheros at all. Because I'm just doing an gentoo-install and found for wireless an intel Intel Centrino Advanced-N 6030. Maybe you have the wrong driver? Wireless here works (worked) fine on Fedora Verne, Linux Mint Debian Edition and Gentoo with Kernel 3.2.12

CJMeyer, 2012/05/31 16:50

I located the problem:

If the wireless wlan is not working after the first installation of linux, it could be that the wireless is hard blocked.
This could be happen because windows may have left the radio (wlan) in a blocked state that Linux cannot change.
If the windows partition has been erased, you might not have a chance to unblock it again without reinstalling windows.

You can check the block status in linux with the rfkill list command:

linux1x:/home # rfkill list

1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes

In this case you have no great chance to bring the wireless to life without reinstalling windows.

I used the system recovery (usb stick or dvd) to reinstall windows (Check, if you have one, before deleting any windows partition!).
I installed it on only one partition (41GB) and brought the wireless to life.

Then I installed opensuse 12.1 on the rest of the harddisk and…. in the networkmanager the wireless could be enabled now.
Rfkill list shows that everything is unblocked now!!!
Wireless is working even after several shutdowns and reboots!!

I made the mistake to erase the whole disk directly to install linux…
So the compromise for this kinds of laptops is to let at least one windows partition on the disk… you do not have to use it.

I will post this for all the guys who spent desperate nights (like me) concerning their wireless which is not working because of the 'hard block yes' - item.

May be there are other possibilities to solve this problem…


joch, 2012/05/22 07:33

Vertical and Horizontal 2 fingers scroll works with the following synaptics commands executed on startup (put them in a script somewhere like ~/scripts/2fingers_scroll)

sleep 2
synclient VertTwoFingerScroll=1
synclient HorizTwoFingerScroll=1

this stops working after a resume so you can add these lines to the previous restore script

export DISPLAY=:0
su -c - <your_user> /home/<your_user>/scripts/2fingers_scroll

export display is required since resume script is executed as root.

A cleaner way would be to add these as options in xorg.conf but I'm feeling lazy.

Ferran, 2012/05/17 00:02

Hi there,

I've just installed Debian squeze on z830. Everything is fine for me unless some FN Keys: FN+ESC (mute) doesn't work and the same thing with FN+Z (retro-light keyboard). Any idea?


joch, 2012/05/22 07:35

Same problem here with Mint 12, however mute key does work.

AL, 2012/05/01 13:30

Unfortunately this solution hasn't worked for me. Have BIOS 1.60, ubuntu 12.04.

Pedro Alves, 2012/05/01 12:14

Anyone has issues with screen brightness? Used to work till one month ago or so (xubuntu), but now the keys don't do absolutely nothing

Scruples, 2012/05/02 11:45

Hi, my brightness controls work ok but never after a “suspend” …. (re-booting returns the controls ok). See the above fix for this in the “Notes” section - I haven't yet had time to try it so I should appreciate any feedback.

joch, 2012/05/22 07:34

Works fine, thanks :)

Álvaro Lobato, 2012/04/26 07:06


Has anybody tried it with ubuntu 12.04?
I'm having problems with resume, the screen script is installed and working correctly.

The system starts resuming, enables the wlan lights and the hd light blinks once, but it doesn't resume.

I can't even open an ssh session, so the problem shouldn't be the script screen.

I've read somewhere that the problem may be the usb 3.0 drivers, and have installed an additional script to disable the module on suspend and reenable it on resume, but it didn't fix it.


Pedro Alves, 2012/02/19 00:18

Now the million dollar question is: how do I upgrade the bios with no windows? (surely everyone in this forum wiped out their windows install immediatly, right? ;) )

Bogdan, 2012/02/19 00:31

No, I still have a windows partition. It is good for stupid things like this one.
You may try to install VBox + some sort of minimal windows installation and hopefully it will work.
Don't forget to enable the Virtualization Technology Vt-x in BIOS.

Please let us know if that worked.

Pedro Alves, 2012/02/19 18:31

Well - tried to install through freedos and didn't work, it's a win32 executable :(

Tribaal, 2012/02/28 08:52

I would love to be able to install the latest BIOS from linux. I will try with a live windows system and report back here. Hope it works!

Monika Cisch, 2012/04/07 12:00

Upgrade bios without win? Actually - not at all, I guess. Linux isn't so disk-consuming that one can't afford a Dualboot, and if it's just for such purposes :) I just left Win on there. Was a bit work to partition properly, as Toshiba had the bad idea to put four(!) primary partitions on there, but it doesen't seem to harm to make one of those an extended one :D

Else, I haven't tried all yet, but until now I'm fully happy. I'm running the Toshiba with Fedora-something (comes with Kernel 3.3) and xfce, secure wireless works without any pain out of the box, sound seems to work so far (haven't tried all yet) out of the box, it tells me that I have a bluetooth and seem to be able to switch it on and off. Haven't tried to connect it to my (elderly) phone yet though.

David, 2012/02/18 12:46

Time to buy my new computer… surely a Z830.

Did someone try the new BIOS 1.60 (posted 3 days ago) which should improve FAN control (the only reason why I'm still waiting) ? Is it better with it ?

Thanks if someone can try :)

Scruples, 2012/02/18 20:12

I have just installed the new BIOS 1.60 and it is fine - I havn't heard much difference in the fan performance but this is truly not an issue. Depending on your operating system the energy management should be set to control the fan speed as the CPU temperature rises. The BIOS setup also has a setting where the fan can be set at maximum speed which is not recommended unless you really need it. My unit runs very quiet and I don't even notice the fan, especially in caparison with my last laptop (Toshiba U200) where the fan was very noisy at times. I am very happy with this machine, it's a breath of fresh air!

Scruples, 2012/02/18 20:14

Just a PS for you to visit this link for other comment on the new BIOS ….

David, 2012/02/18 21:31

OK… thanks a lot. I think I'll buy it next week :)

Bogdan, 2012/02/18 21:33

Actually, I disagree with your statement regarding the noise. At least on my z830 the upgrade made a HUGE difference. Now the fan starts ONLY when it is needed. Before the upgrade was a constant roar from the fan even right from the boot when it was cold.
I highly recommend the upgrade for those like me bothered by the noise. I wanted actually to return this very fine laptop just for the sometime unbearable noise.

Scruples, 2012/02/28 21:00

I bought my z830 in Spain, maybe there is a difference in the originally supplied BIOS - my unit has certainly been quiet from day-1

inwit, 2012/05/01 12:06

Fyi, I bought mine in Spain this week and it had already the 1.6 BIOS.

alex, 2012/02/11 07:12

I'm running Debian Squeeze 6.0.3… when I play back a .mov my laptop locks up and I have to power cycle it. Anyone have that issue?

Pedro Alves, 2012/02/09 10:42

With latest tips, battery life doubled (!) and suspending doesn't affect brightness anymore.

Bluetooth works for sure (kernel 3.0.0-15, xubuntu)

Only extra thing I had to do was to install cpufrequtils to allow changing governor, and I'm still trying to find the best setup to dynamically change the governor when I change to/from battery

Scruples, 2012/02/08 20:02

Just an addendum to my last post. Suspend is now working fine, I found it was my KDE setup that was causing the trouble (no problems with Gnome) - I still can't log in to encrypted WiFi connections using the 3.2… Kernel though.

vicente breva, 2012/04/19 20:09

I'm running kubuntu 12.04 and suspend works at the begining but when I connect wifi, printer applet crashes and then I cannot suspend. Also, sometimes I see “KDE Daemon (kdeinit4), signal: Segmentation fault”. What can I do?

Scruples, 2012/02/06 14:42

My Bluetooth works fine (all functions) on several phones we have at home. Also BT input devices such as a Mouse work well. I can upload and download files via Bluetooth as well as browse the phone contents in File Manager (Dolphin).

The system standby (sleep) and Hibernation seem to be irratic but it maybe due to my SSD becoming full. They worked well at the beginning.

Also something wierd happened since the latest Kernel update to 3.2.2 … (I'm running on Linux 3.2.1-3.fc16.i686.PAE i686) - I can't log in to an encrypted WiFi … so I have to run on the previous Kernel until the next update (which hopefully will fix this problem).

Bogdan Hlevca, 2012/02/06 14:24


Thanks for this posting. I have everything working on this laptop (z830) including the battery backlight.

I cannot control it through the Fn +Z combination though. If anyone know how to enable that please let me know. If you lost the backlight you can restore it in Windows again, but I'd prefer to have all he controls in Linux.

I lost my ability to adjust the back light after applying the power saving settings i915.i915_enable_rc6=1. With acpi_backlight=vendor setting found on this site I got that back. I also get ~6h of battery life with power savings enabled.

I'd also like to add that my bluetooth seems to work. Partially. I can discover devices pair with them. The problem I have is that connecting/sending files to the device does not seem to work.

I am using SuSE 12.1 with KDE4.8. Thanks


Bogdan Hlevca, 2012/02/06 14:37

I forgot to mention that I use 3.2.3 kernel. Maybe this is what makes bluetooth work, but as I said I can't connect. Pairing is fine.

Pedro Alves, 2012/01/21 11:42

I'm using this with xubuntu and everything works including bluetooth.

The only issue is that I cant tune screen brightness after a suspend. After hibernate / restart works again

Anton, 2012/01/16 16:52

About fan noise. It's very awful!

I bought z835 in bestbuy. When I turned on notebook firstly, I was surprised. The noise is very loud and it doesn't depend what you do. Now I'm installing debian and I still hear loud fan noise.

Anybody can help me? I have read this topic but no result:

Did you update your bios? Have you solved fan noise problem with it? Is it possible to update bios in linux?


Scruples, 2012/01/16 17:37

My fan works ok and very low noise, in fact almost inaudible ….. unless you have your ear next to it? I suggest you might have a setup problem if its running on maximum. Have you tried slowing it down through the Toshutils or your energy manager?

As a comparison, if your fan is running on max, it should consume more battery - I can boast at least 5 hours autonomy running on Fedura 16 (KDE).

Anton, 2012/01/16 18:05

As for setup problem I didn't notice any difference between using windows and installing. I still install it. I'll write as soon as I setup it completely.

Just answer some questions:
1)What is your code of model? I mean zxxx
2)What is the version of bios? Did you update it? Any changes of noise?
3)I haven't tried Toshutils yet. What changes did you make? How did it help you?

As for your suggestions to compare running time - it's good idea! I'll test it necessarily.

Anton, 2012/01/09 12:16


What filesystem did you choose before installing Linux? I guess you may have made some changes in bootmenu and filesystem options because there is a SSD drive.
What I have to do to make my SSD work longer without destroying blocks? It's fact, if you often update and rebuilt “the world” your linux system it makes SSD slower.
Do I have to turn off Swap? What do you think about enabling NOOP IO Scheduler? Did you put noatime for mounting partitions?


Scruples, 2012/01/15 16:55

No changes in the boot menu, it was done automatically during Anaconda's install. I re-arranged and reformatted the SSD partitions using the Windows manager, this is an important step before letting Anaconda take control. I also did a defrag from Windows before commencing the Fedora install. From there it was very simple. I did not disable Swap.

Not sure about enabling NOOP IO Scheduler, what is the advantage?

Anton, 2012/01/16 16:46

I guess you use Windows with Fedora? I'm installing only Debian.
I formatted whole ssd and chose using full ssd without dividing into /usr /tmp partitions. I also enabled LVM. The formatting is very slow.
Enabling NOOP IO Scheduler doesn't allow ssd to run unnecessary useless actions.

Scruples, 2012/01/16 17:31

I'm dual booting Windows 7 and Fedora 16. Main reason is the product guarantee since I never touched the Windows installation. This is probably a useless cause because I don't use Windows anymore - I'll probably end up using the whole SSD. All my document files also reside on the Windows partition so I would have access to them from both OS.

Scruples, 2012/01/06 15:48

I'm using:

Gilles Caulier, 2012/01/06 16:56

ok thanks. I will download F16 to test and see if it's better

Scruples, 2012/01/06 18:34

Let us know how things go ….

I'm now using a separate screen (RGB connector), a bluetooth mouse and a USB wireless keyboard - all working fine.

I left it running on battery in suspend mode. When I returned it had gone into hibernation so I guess the Toshiba power saver is working well, even under Linux.

enry, 2012/01/03 22:15

So it looks like kernel 3 recognizes even bluetooth. What about hibernate, suspend, volume and brightness control, function keys, etc…?

Scruples, 2012/01/04 20:12

I haven't tried everything yet but I think that some of the function keys need an extra programme but I haven't had time to investigate yet (Toshutils for ex). However, the brightness, volume and energy functions seem to work well with absolutely no “tweeking” (eg. suspend and hibernate). The wireless function key doesn't do anything yet but that might because of lack of a driver (as previously mentioned), the WiFi however works without problems as does the LAN.

I'll report on battery later but it looks very promising. My experience with Toshibas has been that battery life is always higher than factory specs when using Linux, even KDE GUI!

Can you try SD card reader ?

On my Z830, with some recent 16GB Sandisk memory card, i can see any read error, not reproducible on my laptop…

Scruples, 2012/01/05 15:20

I have just tried a 4GB SD card (from my camera) and it works fine (read/write) - I don't have a larger one at hand. The 4GB was recognised immeditealy.

Using Fedura 16 (KDE)

Caulier Gilles, 2012/01/05 18:12


I can reproduce the dysfunction with 4Gb SD card here. So i suppose it's a linux kernel dysfunction from Mageia Linux.

Which distro you use ? Fedora ? Which linux kernel version exactly ?

Installed Fedora 16 today on the Z830-10F. Once I sorted the partitioning out (a bit complex for me but I managed) it installed very smoothly. I now have three partitions:
1st for Toshiba recovery (untouched) - 1.46
2nd for Windows 7 software and my files : ntfs 88.48
3rd for Linux 29.30

Everything I need is working well, including Bluetooth …. not sure about you gamers, but for professional use, it's great.

A good all round machine (considering my previous laptop Toshiba U200 cost twice the price - at the time) …. :)

Gilles Caulier, 2011/12/09 22:07

The only feature which doesn't work under linux, it's BlueTooth. I have no idea how to hack and debug this part. Any help is appreciate…

Thanks in advance

Gilles Caulier, 2011/12/09 20:04

About fan noise, it's not too important, and aceptable. It's depand of what CPU do. If you compile something huge, sure, you will hear it, else, nothing special (as when you naviguate on the web)

Looks promising! And what a beautiful slick machine it is, the computer equivalent to a well trimmed, stunning female gymnast with a PhD!

Any comment on fan noise?

Gilles Caulier, 2011/12/09 07:13

SSD, it's _NOT_ slow. Linux boot in less than 7s. SSD is fast as excepted for an ultrabook. I formated all partitions using Reiserfs file system.

Gilles Caulier, 2011/12/09 07:11

Under Mageia 1 running KDE4 :

- Battery life : around 6 hours, depending if Wifi is actived or not. Remove one hour if wifi is on.
- Suspend on disk or Ram work perfectly
- Some keyboard function do not work. Volume, brightness, Wifi work fine.

Anders Runeson, 2011/12/09 09:28


David, 2011/12/09 15:25

Thanks a lot !!! Now I have to choose.

Anders Runeson, 2011/12/09 06:51

How about suspend?
Keyboard functions (brightness, volume, etc)?
Powersaving? (what is the expected battery time)?


serdar_villa, 2011/12/08 07:37

Is the retro-light of the keyboard operating also when running with Linux?

David, 2011/12/07 13:59

Could you tell me what's your battery life with this ultrabook (I'm hesitating between portege Z830 and Asus UX31). Thanks.
