Satellite U940 - Keyboard Backlight failure

On my new U940 with keyboard backlight, the backlight does not work after sleep mode. When I restart the computer it works again. I have tried to use the fn + z and upgraded the bios but it did not help.
Is there another way to turn it on or is this an error?
How can I fix this?

It is really strange. In front of me I have U940 and everything works OK.
Open Toshiba system settings and use option Set all settings to default and then use FN+Z key combination.
On my U940 I can enable/disable keyboard backlight using this key combination.
Please test it and post some feedback.

  • Keyboard backlighting failure after keyboard replacement

    I replaced my 2007 MacBook Pro's keyboard this summer after several keys stopped working. The replacement went off without a hitch: everything worked perfectly, including the backlighting.
    Unfortunately this morning, when I went to turn on the backlighting, it didn't illuminate. Hitting F8, F9, and F10 cause the keyboard backlighting icon to appear on the screen, but the circle/slash icon is always visible, and the light never comes on.
    Is this typical of a hardware fault? Or might it be a software problem? I updated yesterday to Mac OS X 10.6.5, but I'm not suggesting that it's related.

    Is this typical of a hardware fault?
    Possibly. System Preferences/Keyboard/Keyboard - *"Illuminate keyboard in low light condition"* selected.
    Try zapping the pram - http://docs.info.apple.com/article.html?artnum=2238
    You probably have no alternative but to take the computer to an Apple store or an AASP. Whichever is more convenient for you if my suggestions do not work.

  • Macbook Pro (March 2010) keyboard backlight failure

    Hi folks,
    A couple of days back my almost mew (March 2010) 13 " Macbook Pro's keyboard backlights stopped working. I had just upgraded to OS X 10.6.4 the night before this happened.
    However, today in the morning they came on for a few minutes, but they flickering like an old tubelight (or like a bulb does when the electric connection is weak). At this moment, they just arent working.
    Could this be a hardware issue? Or maybe due to the OS upgrade? Any other users having a similar problem?
    Thanks.
    Abhi

    I have had exactly the same symptoms described on the same computer -- including the 10.6.4 update. But I have a work around! Just press the V key! light comes back on as long as I hold down the V key. If I mess around with the V key (press it multiple times, the I can coax the keyboard backlight to stay on -- usually for a few minutes, but yesterday it worked all day (even turning the computer on and off several times)
    Pressing other keys does nothing. I have been deleting all but the most useful keyboard shortcuts. I have had keyboard problems on computers before, but none where a one key seems to fix everything.
    I called apple support, and they seem to think it is the light sensor. I don't think so as it dims and brightens the screen correctly. I can also use the dim and brighten function keys to change the keyboard lighting -- just so long as I use my V key trick.
    Weird.

  • Toshiba Satellite S70-B - Keyboard backlight not working?

    Hello, I purchased a brand new Toshiba Satellite S70-B laptop with Windows 8 on it. When I received it, I removed the harddrive and installed a SSD with Windows 7 on it. After getting help from Toshiba support, all the drivers and harware seem to work except the backlight keyboard? I spoken to several Toshiba support techs and finally came to the conclusion to send it in to change out the keyboard. Yet I fear if I send it in, they will remove my SSD and reinstall a hardrive with Windows 8 as their solution. Does anyone have other suggestions... ?? Any help is appreciated.

    I am having problems with my keyboard backlight too. I spilled water on mine and had to totally take it apart, until then  I never had any problem with the shortcut key turning it on and off. I found this last night. Unfortunately. it didn't work for me Also became disappointed when I searched and searched for that magic timer on my desktop he spoke of. Let me know. 1) Shut down laptop
    2) Turn on and start tapping the F2 button until you get to the BIOS screen
    3) Scroll over to power management and change the setting for your backlit keyboard from off to on.
    4) Press F10 to save and continue to start up.
    5) Enjoy.
    Believe it or not, I JUST fixed this issue on my own a665D laptop. I am still tweaking it though because after this, the shortcut keys don't allow you to turn the backlight off so I'm typing on a keyboard who's LED's wont go off as of yet. But this should help for now.--REVISION: I am done "tweaking it" as I have found the answer and it was glaring me in the face. Instead of just turning it to the ON position through BIOS, turn it to TIMER. You can set the amount of time you want it to stay on when ever you press a key and the FN+Z shortcut works when this is set up so you can turn the keyboard on, off, or to follow the timer right from your desktop. I hope this helped.

    You are officially awesome. Worked perfectly; I never would have ventured into the BIOS without an exact guide like you gave (Would have blown up the laptop or something lol). But anyway, thanks so much,

  • Does Satellite P750-10E supports keyboard backlight?

    Hello,
    Yesterday I bought Toshiba Satellite P750-10E and I'm not sure if this model has keyboard backlit, because in few reviews I saw that this model has keyboard backlit but I dont have it, or dont know to turn it on.
    Please help me to fix this problem, I really need keyboard backlit because many times type in dark room. :)
    BTW this is awsome notebook, Im very greatfull and happy to have this model, just need a keyboard backlit if its possible to turn on.
    Thank you for answers. :)

    Hi
    Checked the user manual of the P750-10E but didnt find the info that the keyboard backlight would be available I think the notebook does not support this feature.
    Furthermore if the keyboard would support backlight, then the Z button should contain a tiny sign which would refer to this feature.

  • Has Satellite P850-30V keyboard backlight?

  • Satellite S55 BIOS update to 1.60 has a problem with UEFI keyboard backlight control

    I recently updated my BIOS to version 1.60 from 1.50. The update went well. However now the setting for the keyboard backlight control will not hold my setting. I don't wish the backlight to illuminate as it will use up power. When I enter my UEFI and change the setting to "OFF", then save and exit, the keyboard illumination appears to operate as expected. However, following a Windows restart, or shutdown and boot, the UEFI setting resets to "TIMER" with "Backlight Lighting Time" set to 0. If I leave the mode set to "Timer", and set "Backlight Lighting Time" to 10, again the backlight appears to operate properly. But a reboot resets the time to 0. I thought possibly I was not saving and exiting UEFI properly. To test this, I change the setting for the "Internal USB3.0 Controller from "Enable" to "Disable", then also set the backlight control to "OFF", did a save/exit. I found that the USB3.0 remained disabled, but the backlight control again reset to "Timer". The BIOS update was provided by the Toshiba Service Station app as an optional update, so it should be the right one for my laptop. Any help would be appreciated.
     My laptop is a Satellite S55-A5295 and is running Windows 8.1 with BIOS 1.60 and EC 1.20.

    Thank you for your response. When I purchased the laptop, I also bought a 2-year repair plan with Geek Squad.  I took the device to the tech and it was his opinion that there might be a bug in the BIOS I installed.  I asked if we could retro the BIOS to a previous version and he told me he didn't recommend it as there are always risks when updating the BIOS.  He said it wasn't worth it as the device was stable with no other known issues besides the keyboard lighting.  He recommended I contact Toshiba support to document the problem.  This I did.  However, I was told by Toshiba I was beyond my complimentary support and would have to pay $49 to correct the issue.  I agreed to purchase the support.  The tech had me try various resets including the hardware reset button but to no avail.  At this point the tech informed me that I can always press "Fn-z" to cycle the lights off after boot/restart, and that my support time was ending.  I only hope that the problem is with the BIOS and not with hardware such as BIOS memory, and that a new firmware update will correct the problem. I appreciate this forum and the people that are trying to help others correct their problems.  Please keep up the good work. 

  • Screen backlight and keyboard backlight not working

    Yesterday I turned on my old but proud PowerBook17" and the *screen was black*, but you could barely see everything. *Also keyboard backlight is not working.*
    I read many many forums and all say that black screen caused by inverter failure, but in my case keyboard lighting is also dead, so I wonder *if this is something different* and not the inverter.
    I would appreciate any advises or ideas cause I love this machine..
    Thank you in advance!

    Same problem here.  I initially thought the auto-brightness problem had been fixed in 10.7.3, but sadly it hasn't. The auto-brightness works when the Mac starts, but I find it loses control and fails after wake from sleep. 
    I have telephoned AppleCare several times but they are not aware of this bug.  They think a PRAM reset cures it, but it doesn't.  As soon as the machine goes to sleep then auto-brightness fails on wake.
    I have used the Apple Form to report the bug.  It might eventually get fixed if others would kindly report it as well please.  Here is the link:

  • Satellite U940 Hangs At Leading Innovation Screen

    Hi,
    I own a Toshiba U940 Ultrabook and yesterday I booted the laptop with my USB drive in the USB port. It seemed to try to boot from the USB drive and was on a black DOS like screen for a few minutes, since the USB drive wasn't bootable. I tried turning the laptop off to restart it, but pressing the keyboard didn't work, so I ended up pulling out the laptop battery.
    When I plugged the battery back in, the laptop started and then at the Leading Innovation screen, it loaded some text saying the laptop didn't shut properly and it was loading some files/doing temp repair. However the laptop hung at this screen for ages as well and this time I held the off button to turn the laptop off.
    Upon turning my laptop back on again, it now hangs at the leading innovation screen and stays there indefinitely until I turn it off. I can get into my BIOS if I press F2 early enough in the boot sequence and I can also get the boot options loaded if I press F12 early enough as well. I have no system recovery partiton on the laptop atm due to doing a clean install of windows using OEM disks.
    Does anyone know whats causing the laptop to hang at the leading innovation screen. This is very frustrating because I have never had this issue before with any other laptops, even if I pull the battery out to restart it.
    Thanks all

    hello

  • What is the Keyboard Backlight attached to?

    Hey there.
    A while back I spilled some milk on my macbook pro 15" old model (NOT the unibody) keyboard and although I finally got the sticky keys issue sorted out (I spent a good 5-6 hours on my day off taking off all the keys and cleaning them, and then putting them back), the backlight of the keyboard doesn't illuminate the entire keyboard anymore.
    I went to my local Apple store's genius bar and they told me that by replacing the keyboard (for a mere $150 USD), I would also be fixing the backlight. I took my macbook pro to my local MacTek, however, to compare what they would quote me for replacing the keyboard, but THEY said that in order to replace the LED light I'd have to replace the top case, and the keyboard alone wouldn't do it.
    Then I take it back to the Apple store (MacTek was more expensive due to their having to order parts) and ask them about it and this time they tell me that I WOULD have to replace the top case to fix the LED, which would cost $300+. Obviously not worth it just to fix the backlight when nothing else about the top case is visibly wrong.
    Then I get a little curious when I get home and do a google search for the makeup of the keyboard and find a site with pictures that show the LED IS actually part of the keyboard O_O I dunno what to believe here.
    Assuming my goal is to fix the LED keyboard backlight, just what is it that I'd have to replace?

    Thanks, that's exactly what I needed to know.
    I'd click "solved" for your post but actually I have one more question. I took the MBP to a certified repair shop, and they order a keyboard from apple. Last week (7 days ago) they said they received the new keyboard and were replacing the old one now.
    Then, an hour or two later, they called me back and told me that they think Apple sent them a defective keyboard, because now for some reason my computer "won't turn on." O_O
    So I called them today and the guy just said he's waiting on the second replacement keyboard. My question is, can that realistically happen? That is, a bad keyboard causing the entire system not to be able to turn on?
    (good thing I backed up before taking it to get repaired, eh..?)

  • MacBook Pro keyboard backlight not switching off

    I recently bought a 13" MacBook Pro (2012, 2.9GHz i7) and it came with Mountain Lion preinstalled. The keyboard backlight isn't behaving as I had expected: when the "Adjust keyboard brightness in low light" option is checked, it does indeed adjust the brightness of the backlight when ambient light levels change. However even when the ambient light is VERY bright (desk lamp shining down) the backlight doesn't switch off; instead it just goes to full brightness. I understand that the backlight usually dims in dark conditions to save battery, but why would it go bright when the keyboard is fully visible without a backlight? Is there a way to make the keyboard backlight go off when there is plenty of background light and come on when the environment is dark?
    Thanks in advance for any advice.

    Auto brightness operation usually works in the way yours is working.  It is dimmer in very low light and progressively gets brighter as the ambient light increases.  There are cases where this is actually helpful as in wierd backlighting situations.
    You can override in the System Settings and from the keyboard "function" keys.  I'm not at my MBP right now, but I think the keyboard backlighting controls are somewhere near F5 and F6.

  • MacBook Pro Mid 2010 13", Lion 10.7.2, keyboard backlight / ALS not working

    Since upgrading to Mac OS X Lion I have had problems with keyboard backlight and the ambient light sensor. I realized that the problem seems to be caused by ambient light sensor or hardware detection issues. LCD is not auto-dimming with light intensity variation. Since then I've done a Snow Leopard clean install and upgraded to Lion with no success. Then I have done clean installs of Lion using USB Keys with versions 10.7.0, 10.7.1 and 10.7.2 and the problem persists. Under Snow Leopard everything works like a charm.
    SMC and PRAM reset did not solve the problem.
    When I press F5 and F6 to adjust the backlight nothing comes up on the screen.
    No settings under Keyboard menu.
    Any ideas on how to solve this?

    Max,
    I have the same model MacBook Pro as you. Have you tried erasing your internal disk, reïnstalling Snow Leopard from your grey Mac OS X Install DVD, and running Software Update to get it  to 10.6.8, to see if it also misbehaves under Snow Leopard?

  • Problem with Macbook Pro early 2011, webcam not working in any apps and windows 7 or 8 on bootcamp, keyboard backlight not working?

    Hi Guys
    I recently bought a second hand early 2011 Macbook Pro 15 inch and are having 2 problems. The first is that none of the apps detects my webcam at all, the second is, i have Windows 8 installed on bootcamp but are unable to get the keyboard backlight to work in 7 or 8. The backlight works perfect in os x 10.8.5 though. I need a little bit of help guys.....

    Go to Apple Menu / About This Mac. Click on More Info ... next on System Report. In the left hand column, under Hardware, select USB. The right side will show the USB Device Tree. Look through that and check for "Built-in iSight". That is your camera. If it is not listed the camera is not working.
    For backlighting, try this: go to System Preferences / Keyboard. Uncheck "Adjust keyboard lighting in low light".

  • MacBook Pro (mid-2010) keyboard backlight lags after 10.6.8 combo update

    I'm one of those who take the extra time to perform major updates on my MacBook Pro very carefully. I always perform all the permissions and disk check/repairs, typically running something tried-and-true like AppleJack. I then always use the combined updater as opposed to the delta, fully downloading and applying it in Safe User Mode. So, I never run into the typical problems. That said...
    Is anyone who has otherwise had a successful update to 10.6.8 on a MacBook Pro with keyboard backlighting experienced a sudden lag-time with the backlight coming on when touching the touchpad or pressing a key?
    There is a definitely perceptible 1-second-ish lag I'm experiencing and I'm hoping it will be corrected quickly with either a firmware fix or an update.

    Same here, although I have a MBP mid-2009.
    The 1-2s lag is VERY annoying if you've gotten used to the old instantaneous light-up with previous SL.
    I've fired off a bug report to Apple - here's hoping they don't just bury their head in the sand and release a fix quickly (I also hope they don't have the same bug in Lion as well, I'll be getting that soon)...
