Lenovo b570 Backlight not working

Hi all,
Had a few problems with my b570 (think the hard drive might be screwed)
But tried to wipe it all and start from fresh, and after not being very successful left it alone for a few months.
Im trying to have another go at fixing it now and the backlight on the screen is not working, there is no real reason for it to have stopped working as it hasnt been moved in months, the screen is still working but is very dark if i get real close i can see what it says.
do i need to replace the whole screen or is there something i can do to maybe get it working again?
Thanks

hi robk87,
Welcome to the Lenovo Forums.
If you get the no backlight issue after you turn ON the computer and adjusting the brightness (via Fn + up/down arrow) have no effect then you may need to replace the entire screen.(looking at the spare parts, the B570 uses a LED-backlit LCD display - these types of display doesn't have an inverter which powers up the backlight).

Alternatively, you can try using an external monitor and connect it to the VGA or HDMI port (selected models) to get a display.
Hope you get the computer fixed soon.

T400 Backlight Not Working

I got a Lenovo T400 and the backlight stopped working (LED). Anyone have any ideas?

I am having a weird problem where every 1/8 or so LEDs is not working - it looks like a bad solder joint deal. At the bottom of my screen I get a row of dark shadows that are evenly spaced apart. I took this to a shop to fix a year ago, but now it's back. If i pinch the lower right hand corner of the screen, the shadows will temporarily go away.
My computer is out of warrenty, should I just go ahead and open it up with a solder gun?
Also, the pics you have of the screen would be great, so I can see what I'm looking for.

Fingerprint reader on Lenovo KUF0452 keyboard not working with Lenovo X240

Hi,
I have a Lenovo KUF0452 keyboard with built-in fingerprint reader. Up until a month ago I had a Lenovo X220 laptop which co-existed happily with the keyboard - I could unlock Windows with a swipe of the keyboard's fingerprint reader.
I've now replaced the X220 with an X240 and can no longer unlock Windows using the keyboard's fingerprint reader - I just get this error on the Windows lock screen:
A match for the fingerprint was not found in the fingerprint database.
I have Lenovo Fingerprint Manager Pro v8.01.35(x64) installed and have used it to enroll a couple of fingerprints for the X240's fingerprint scanner, but when I try to use it to enroll fingerprints for the keyboard's scanner the app's progress bar doesn't move off 0%, so I assume the app isn't accepting the keyboard's fingerprint scanner as a valid input.
The X240 is docked, with the lid shut, so I have no easy access to the laptop's fingerprint scanner which is why I want to use the keyboard's fingerprint scanner to unlock Windows.
How can I get the keyboard's fingerprint scanner to work with my X240?
Kind regards,
/Neil

hi jenniby,
Welcome to Lenovo Community Forums!
I believe it is the Lenovo B570 you're saying,
Try doing a power drain,
Remove AC adapter and Battery, then hold down the power button for at least 15 sec. this will drain off the power from the MOBO.
Reconnect everything and see if that works,
Also try using an external Keyboard to test out the Windows.
If that did not work I suggest Calling Lenovo Technical support for Hardware Concern.

T430 - Keyboard backlight not working

Hi.
My keyBoard backlight is not working.So may i know how to resolve this issue and i am not sure also if this feature is available in my laptop.
Regards

Hi,
I have excatly the same problem, I have bought a laptop including an US backlit keyboard and all first three options of pressing FN+space noting happens and then the Thinglight is ok.
I can see very low light under the keys but it does not light the keys and it is useless.
Is it a definetely a hardware problem, when I removed the battter to try to reboot it and I can see through the cover cage that eveything under is well stacked even over stacked and like a bag with cloths rather than nice and lean set.
I am so disappointed that this a fault of Assembling. I have doubt that the the backlit is ok but the assembly engineer has forgotton to change the keys itself. It is a shame. It is very expensive configuration, and now I am on buisness trip to London, Europe, and dont know what to do? Can I contact Lenovo there, it doesn seems that I am going back to US for next three months
Regards,
George

Lenovo AIO C440 - not working infrared remote control

Hello,
is there any hint how to get infrared remote control working for a new C440 model? Tomorrow I will try to measure and/or replace batteries which could be bad. For now it is totally not working.
Another question: the remote should work only within AverMedia TV app or in the whole Windows 8?
Regards,
Zdenek

hi bohdik,
Welcome to the Lenovo Forums.
The IR Windows Media Center remote control is for use with C440 models with optional TV tuner. If you have this model, make sure the TV Tuner driver and the ITE CIR Driver from the lenovo support site are installed under Device Manager (press Windows Key+R then type devmgmt.msc) then follow the Set up a TV signal in Windows Media Center. guide.
Note:
You must have Windows 8 PRO to enable Windows Media Center
See this articles in reference:
How to add Windows Media Center to Windows 8 Pro
How To Install And Set Up Media Center On Windows 8
Hope this helps

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".

Bluetooth, iSight and Keyboard Backlight not working. Please help!

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!
Alvarock.

****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.

Macbook Pro 17inch late 2011 keyboard backlight not working

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

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:

Keyboard backlight not working on MBP 13in Mid-2010

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!

Keyboard backlight not working...

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,
Simon

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

Keyboard backlight not working - settings missing on MacBook 2,1??

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!!!!

Satellite C50D-A-138 backlight not working

Hi, I am having a major issue with my laptop. The backlight for the display will not work. I can only faintly see the picture. I tried adjusting brighness, no joy. It outputs fine to a monitor. I have tried replacing the screen and the connecting ribbon but the issue still presents itself. Does anyone have any ideas??? I am at a loss.
Paul

Hi
Connect external monitor and check if the same display problem would appear on the external display.
In case everything would appear properly on the external display, the problem must be the internal display panel.
The notebook’s display panel seems to use a LED backlight as the light source.
So probably the display’s backlight doesn’t function correctly. In such case the display panel must be replaced.
You should ensure that you are using compatible panel because many notebook displays support different technology (TFT panels without backlight and display supporting backlight like the one build in the C50D-A)
