Toshiba Satellite Keyboard Backlight Not Working

Hi I have a Toshiba laptop. The backlit keyboard has stopped working. Is there an on off switch or does the light require replacement. Its less than a yr old. See More: backlit toshiba keyboard not working.
I have a Toshiba laptop model R390. I cannot, for the life of me, find the key to turn ON the BACKLIGHT. I have browsed the web for several hours and asked many questions. But to no avail.
Keyboard back-light now persists after boot, keyboard controls don't work (probably a distro issue not a kernel problem). The command su -c 'echo 0 brightness' for the illumination device now toggles both mouse illumination and button strip illumination (previously only mouse illumination).

Toshiba Keyboard Backlight Not Working

I just got it in July and the backlight keys have already gone out. I don't know if its because of powering it down and it being on low batteries ( it likes to put its self to sleep even when I push the button to shut it down I will think its shut itself down but it puts itself to sleep). I have tried pushing the FN + Z but it seems not to work for this type. I also have windows 8.1 on my.

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,

Hello,
A month ago I purchased a Toshiba C660-1FE. After three weeks my HD broke down. I bought a new HD from Western Digital and replaced the broken HD. As I did not make an recovery image of my HD, I had to order the Product recovery discs off the Toshiba website (3 discs, of which disc 1 and 3 were the only one's required for installation).
Now, I have the problem that my laptop keyboard does not work. I am currently using a USB keyboard and mouse to replace my keyboard and touchpad of the laptop.
The laptop keyboard works fine in BIOS. Therefore, I hope it's just a driver problem.
I have:
tried finding and installing lots of drivers on from the toshiba website, no result.
tried changing settings in the bios (usb enable/disable).
tried to fix the problem by re-installing the entire computer again several times.
The keyboard seems to work until windows loads. When the system is starting up I can press caps lock and num lock and the green lights come on. This all stops working once the windows startup symbol appears.
Perhaps a second problem in the device manager: under the display-adapter, 2 subcategories have exclamation marks: it says Mobile Intel(R) 4 series express chipset family twice! I can't seems to fix these with any drivers I can find either. When I check the settings I have this message (google translate since it was in dutch):
+The digital signature for the drivers for this device is required, can not be verified. Possible after a recent hardware or software change a file that is installed incorrectly signed or damaged, or is malicious software installed from an unknown source. (Code 52)+
+You need to restart the computer to this device changes to take effect.+ (obviously I tried that too)
Can someone please give me some help? I am at the end of my wits.
Sincerely,
Daniel
Hi MisterX,
thank you for your response. I have tried these things and there is no such thing as PS2/keyboard in device manager. It's as if the Hardware is not even recognizable in windows. I am starting to doubt whether I got the right Backup CD.
I wrote the following e-mail to [email protected]:
+Dear Toshiba,+
+after receiving the recovery CD's for my toshiba c660-1FE, it turns out that the drivers for the keyboard and touchpad are not installed. I have tried many things to get around this but it seems to me that I have received the wrong product recovery CD's. The chipset drivers are not the right ones, the overall layout of this version of windows 7 is different from before and when looking for answers in the toshiba forum I have concluded that the recovery CD's could be the wrong ones.+
+My laptop: Satellite C660-1FE+
+serial: 5B378048K+
+Part-nr: PSC0LE 02M0TU26DU+
+Recovery CD's I received are CD's 1-3 with serial R14254DU+
+Would you be so kind to check whether these CD's should be 100% compatible with my laptop?+
+This would be greatly appreciated,+
+Daniel+
MisterX, do you know any other emails I can forward this too? Or anyone who could perhaps tell me if I got the right CD's? They are taking their time to respong to this...
Kind regards,
Daniel
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'.
My Bluetooth stopped working along with my iSight and Keyboard Backlight. I first noticed the weird sign over the bluetooth icon, and it read 'Bluetooth not available'. I payed no attention to it for a while until I tried to take a picture with Photo Booth and I read 'No camera found', for some reason I tried to dim the backlight on the keyboard and a blocked sign appeared under the brightness level, not letting me do anything (Later I was able to use the backlight with the LabTick app). I have tried everything. SMC, PRAM, NVRAM, logging as diferent and new users, booting in safe mode... every solution I have found on the internet has been tested by me. Then I read this about the Hardware Test solution, and surprisingly after performing the Hardware Test no problems were found! So basically my MacBook Pro (mid 2010) is not having any trouble of any sorts with anything. Then why can't I use Bluetooth, iSight or Key backlighting (which only works through LabTick). Given the fact that the hardware test shows no problems I am not comfortable with the idea of taking it to repair. There MUST be something I can actually do to fix these issues.
Does anybody have any idea? I repeat, these are NOT WORKING, NOT FOUND AND NOT AVAILABLE.
- Keyboard Backlight (Only works through LabTick)
- iSight Camera (Not found by any software)
- Bluetooth (No info appears on the system profile, the icon on the menu bar is completely gone)
All three issues happened at the same time, the night before everything was working perfectly fine.
If anyone could help... please!!!
Summary:
MacBook Pro Mid 2010 (http://support.apple.com/kb/SP583) Unibody, can't take out the battery.
Solutions tried:
- Reset SMC: Turning on while holding Shift + Ctrl + Option + Power Button (This makes my MacBook forget about the battery and start up with really loud fan noise, battery icon appears with an X on it, keyboard backlight buttons work, they show brightness level on screen, but the actual light won't work, no bluetooth, no isight)
-Reset PRAM and NVRAM: Turning on while holding Option + CMD + R + P (I have waited for 2 chimes, 3 chimes and 4 chimes at different times, nothing happens. Light, bluetooth and isight are still gone)
-Holding Power Button for 10 seconds, 20 seconds, longer... nothing changes.
-Creating and logging in as new admin user, nothing changes.
-Deleting the bluetooth.plist file and powering off and on again, also rebooting
-Deleting the SystemConfiguration folder, powering off and on again, also rebooting
-Installing 'blueutil', didn't help at all, turned it off via terminal with command blueutil off.
-Performing Apple Hardware Test - Shows no erros or problems on any area after one full hour of testing (Performed the extended testing)
-Leaving it powered off overnight
Please anyone help meee!! I can't afford going crazy!
Thank you so much in advance!

****UPDATE***
Hi guys i got across this forum after searching for bluetooth, front camera and the most ANNOYING no lost keyboard backligth.
After run all the test, procedures, tweeks and, and everything i remenbered that once i sent my MBP to repair at you bring i break, turns out that the little ribbon flex connector coming from the mother board ( from the rigth to left) was loose since the adhesive wich they used shrink do temp changes, anyhow y popped out the glas and found the flex cable totally sticked to the glass pulling out of the pcb board connector, reinstalled it smoothly and that FIXED the camera, bluetooth and keyboard backlight!..
thats it. hope i helped some frustraded owner.
After installing Boot Camp 2.1, I can't get the keyboard backlight to work anymore. I am in the darkest of dark rooms. Pressing F8 just shows an attempt to turn it on but it has a circle with a line through it.
I am running Windows Vista 32-bit SP1.
Are there drivers I can install manually?
Thanks.
Here is something funny. I rebooted with the room completely dark. When Windows came back, the keyboard was backlit. But, when I turned the lights on, the keyboard stayed backlit. And, even better (or worse), when I rebooted again, the keyboard just stayed backlit even to the point where I was choosing between booting into OS X or Windows. That is crazy! I don't know what is going on anymore.
Help,
My keyboard backlight stopped working when I upgraded my Macbook pro (retina) from Mavericks to Yosemite. Nothing in System Preferences -> Keyboard makes a change. This is a feature I use a lot. Any help will be appreciated. Thank you.
Try a SMC reset:

Ciao.
Recently near the end of sum me 2014 I only noticed the backlight keyboard not working at all. I have done the following to try and rectify;
1. Reset SMC
2. Rest NVRAM
3. Disconnected battery and the above
4. hardware test online, result showing no issues found.
with all outcomes proving nil. Pressing Fn + F5 or F6 does show the brightness either increasing or decreasing but with no light. I then opened her up and disconnected a cable that was to the LHS of the RAM boards but this only powers the White Sleep LED and not the backlight keyboard on this 17inch model. My next step is to remove the mother board and find the actual cable that does power the backlight LEDs and ensure that it is connected. Similarly around the same time I noticed this with the backlights the fans were running fast. However the weather has gotten cooler and the mbp is not running fans as it was when it was in the warmer months.
Do I have to remove the motherboard and actually make sure that the connector for the backlights hasn't been dislodged?
Anyone out there with a 17inch mbp late 2011 that has had this problem please help.

Thanks Ogelthorpe, I found an excellent video (not in english but it didnt matter) https://www.youtube.com/watch?v=8HNAGodYMNA .
What I found was that the keyboard backlight is intergrated into the black plastic cover that is between the motherboard and the back of the keys/LEDS and its all one piece back to the connector that connects to the motherboard under the LHS fan. I need more details to find out if the LEDS are controlled by a chip or what, but it seems to me that I need to visit an apple store/repairer, however this will be really difficult for me as Im in an isolated location. If there are further tests that I can conduct on my own, I would be grateful. Even if there are tests that Apple themselves conduct to find out what the problem is

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:
http://www.apple.com/feedback/macosx.html
The backlight on my keyboard is no longer working. When my backlight 1st stopped working it allowed me to toggle the brightness level to no results (I even tired lab kit.) After I resetmy PRAM and SMC I couldn't even try to toggle the brightness. The illumination settings in System Preferences disappeared as well. Is there anyway to fix this without having to bring my computer into the Apple Store? I use this machine for both work and school and cannot be without it for a few days. I am currently running Lion.
Are you under warranty? If so, call Apple and report the problem and get a case number. If your warranty is about to run out, it is important to get a case number to document that the problem first occurred under warranty so that Apple can eventually fix it under warranty.
You have already tried the usual cures--resetting the SMC and checking your settings for the keyboard. If LabTick also does not work, then you likely have a hardware problem of some sort.
It might be worth a trip to the genius bar to have them take a look at it and maybe run their hardware test, just to get a diagnosis and repair estimate. You can also ask how long the repair will take and see if there is any possibility of having it repaired while you wait. Once you know what's wrong and what it might take to fix it, you can delay the actual repair until a time that is more convenient to you.
Right now there's no way to tell what's wrong--it may even be something as simple as a cable that needs to be reseated. If so, it should not take long to fix.
Good luck!
Hi everyone!
I am having a problem that appears to be shared by other Powerbook users who have the luxury of a backlight for their keyboard: I have updated OSX and now the option of automatic illumination has gone from the Keyboard and Mouse preferences window?
Does anyone know how this can be fixed? I have only had my laptop for 13 months and so far my hard drive has died and the system has crashed completely three times, I would be devistated if this is the logic board now? If you think it is please lie!? Only joking of course, but if anyone has a neat solution I would love to know!
I have already tried to set-up a new user, and have removed the com.applebezelservices.plist from the library, but no joy so far.
I use this luxury lots, since I work at night. Any help would bring festive cheer to me and my children to be!!!
Regards,

Same problem here with my powerbook 15' 1.5ghz.
It seems that this problem is common with a lot of people as I can see from the forums that I went on.
The ambient light sensor seems defective since a software update (probably the 10.4.7). Results are that the auto-dim of the screen does not work all the time, the keyboard no longer backlight up in dark condition and the sleeping status light blinks for no reason or it stays on when computer is open.
I've tried to zap de PRAM and reset PMU with no results.
I've read that some people has a loose connection between logic board ans ambient light sensor... could that be the reason as you mention taht they told you so?
I've read that some people with the same problem had their Logic Board changed as they were under warranty... but for the rest of us that are not on the warranty anymore... no answers from Apple. I think that they should open a repair ticket and that everybody who has this problem should contact Apple
I have a macbook 2,1 that was given to me by a friend about 6 months ago. It is in perfect condition except some seperation around the edges. So, I took into the Apple store a couple of days ago and they replaced the entire 'inside' of the macbook; meaning screen surround, keyboard and surrounding 'faceplate'. (Excuse the incorrect terminology) I also mentioned to them that the keyboard didn't have any backlighting (at least I have never seen it) and the tech said would also be repaired as a result of the keyboard replacement.
ANYWAY, I am home and the keyboard backlight is still not working. I searched mac help and found the following:
To set keyboard backlighting for a portable computer:
Choose Apple menu > System Preferences, click Keyboard & Mouse, and then click Keyboard.Open the Keyboard pane of Keyboard & Mouse preferences
To enable backlighting, select the “Illuminate keyboard in low light conditions” checkbox.If you want to automatically shut off the backlight when your computer is idle, drag the slider to indicate when to turn it off.
The only thing I saw was an option for bluetooth - n/a, keyboard shortcuts settings to change shortcuts..obviously and the keyboard setting which only gives me the choice to
1. change the key repeat rate
2. change the delay until repeat rate and 3. a box to check/uncheck if I want to use the f1, f2, etc as the standard function keys.
There is also a button at the bottom left corner which says 'modify keys' which I believe is n/a.
I should also probably mention, when searching help, it also said 'The light sensors are located in your computer’s speaker grilles, so make sure the grilles are not covered when you use your computer in low light conditions' . I have no speaker grilles (that I can see) but my speakers work. and it says; 'IF the keyboard on your computer can be backlighted, you can set it so the keys can be visible in lowlight conditions'. I guess the keyword here being IF so maybe this mac isn't supported for that but I think that it is from what the person at the Apple store told me after looking up my serial number.
Just to add, I did search the forum and found close to the same problems but with different types of macs so I thought I would ask. I am still learning the ins and outs of using Mac so I hope I asked the right questions and I'm not over expanding on the question too much.
I am sure there is a simple explanation...maybe?! So if someone could enlighten me, I would be very grateful!!!!
Thank you!!!!

I have a Toshiba Satellite A505-S6033 that all of a sudden does not have its ac power and batter power indicator lights working. The power and hard drive activity lights do however work. The laptop works fine on both AC and battery power as well as the battery recharges no problem. I tried the cord and pack from my other Toshiba laptop and still no lights. I also changed out the charge cable with a new one after this assuming a short in the cable. Still no lights, however everything works. Please help as I am at a loss why only these 2 indicator lights out of the whole strip do not illuminate as well as the laptop still works fine. Thanks in advance for any help you can provide me.
leds burn out too. you could replace or just use as-is. they really aren't necessary anyway.

So up until a couple weeks ago, my internal mike on my computer was working fine. Then the other day when I tried to use skype it would not work. When I go into sound->recording devices it says that the 'front mic' is not plugged in. When I click on it thought it says it is working properly. I tried to download and install the driver from toshiba and it said that it installed correctly but this did not fix my problem. I read here that some other people have been downloading a new BIOS and that that helped? would that be able to help my computer? i have windows vista home premium 32 bit i believe. any help would be appreciated

Let's just try a proper system reset and see if this helps bring your mic back. Power off your system, unplug everything including the AC, remove the battery, press and hold down the power on button for 30 seconds, replace battery and AC, power on, when you see the Toshiba logo press the 'F2' key to enter BIOS Setup, in setup press 'F9' to load setup defaults, press 'F10' to save and exit, boot into Windows, and test your mic again.
Please let us know if this helps. Good luck.

Hi, I'm posting this for a friend with a new Macbook Air. He says that his keyboard backlighting does not work when he is using it for Windows (don't know which, but probably Vista). Any ideas why? Thanks. Gary
Install all the drivers needed when running boot camp - try for example inserting a DVD - then press the eject key - See if it comes out - If it doesn't install all the drivers - try Control Panel - If not try re-installing your version of Windows.
Good day! A few days ago has turned off keyboards backlight of lenovo Z500. I tried to reboot the laptop, but backlight still doesn't work as before by pressing FN+Space buttons. I hope this is a software bug and I could solve it without help of service center. But I can't solve it without your help, as the website and the Internet has no effect, and I have no desire to reinstall the system because of backlight. Maybe someone knows how to make it work again?
