Lenovo ThinkPad W Series :: W500 Brightness Not Working
Jul 4, 2010
I have a W500, ATI Mobility FireGL V5700, Windows 7.
When I press FN+Home and FN+END to regulate brightness up or down, the brightness symbols turn on and goes up/down, but the screen brightness is not regulated up or down but stays constant somewhere in between.
What can I do to get "brighness" working?
It has never worked, the computer is 2 months old. I have upgraded from Windows 7, 32 bit to 64, but brightness is still not working.

I've got thinkpad W500 and the PrtSc key is not capturing screen I want to copy. It doesn't require the Fn key because it's labeled on top row ("sysrq" is below it on 2nd row on same button key).
-I also tried pressing Fn + prtsc just to see if that would work. Didn't work.
-Then I tried pressing Alt + prtsc... nothing.
-I even tried pressing Ctrl + PrtSc.... nothing.
I've looked all over Forum, no one addresses this, or at least not for the W500 (which is different from the other W510 through W540 series laptops. Or other ways to capture a screenshot?
Windows 7 (64) W500 4061-BV3

I have a thinkpad W500 and I'm reinstalling Windows 7 after years of running linux (I got tired of my video drivers being unsupported due to the age of the card). However, when I attempt to install system update, I get the message "an error occured while gathering user information" and I cannot continue. How can I get the switchable graphics, power, and keyboard drivers properly installed? I don't really care about the rest of the software, it just that system update is the only way I know of to get it.

I just got the x120e and I already went through and fixed it auto-brightening itself. After I hit the Fn + Home and adjusted it to my preference. It was not on the charger when I did that and I was in a darker room so I had the brightness down lower. Later on in the day, I plugged it in to charge and I went to make it brighter. The brightness is not changing however. All the oher Fn + F keys are working. Just not the two for brightness. The weird thing is, I shut the computer, waited for it to enter sleep mode then opened it up again and it was really bright and I had to pretty much squint, but again the keys were not working to lower it. I closed it again and opened it and it is again dimmer. The keys still aren't working.

Why neither the display brightness slider nor the F8/F8 brightness function keys cause any change to the display brightness? It used to work but for the past few weeks it's not. I thought that slider was able to override any preset power settings.

In fact, my W500 is over 5 years old but I do not have any complaints on its performance except the WUXGA display is rather dim which makes it hardly useable on open-air. I do not recall that problem at purchase time. When googling around I see different reasons for a dim display
a) cabling - would not consider this beacuase the screen is not flickering and does not show any discrepancies - it's just dim
b) inverter - this is not a real inverter, is it?
c) display panel - it does not seem very difficult to replace
d) motherboard - I am unsure whether I would challenge a replacement
Is there a way to find out which way to start working around? I mean buying a panel if it comes out at the end that I had needed a new motherboard would rather make me blue.
Or should I accept the fact that time has gone and I have to look for an other computer because it does not worth bothering. What do you think?

I have Thinkpad W500, Windows 7 Professional, 64bit. When I turn on laptop, i forget when (before or after Windows loading) it brings me to the FingerPrint icon. This part is ok because the laptop seems to continue booting without my clicking it which I prefer. (I don't even have my own FingerPrint saved in laptop and I find that strange. I bought this W500 used). After FingerPrint icon disappears, the User or Admin Icon is shown on screen. That picture needs to be clicked for laptop to continue booting up or loading up. No password required, just click the icon. I'd like for laptop to just bootup without doing anything, and go to the desktop page automatically (like all my other thinkpads).
How can I turn off that second Icon or feature? Is it a User or Admin icon? I'm only user of laptop so I don't need feature to use a password or to click the Icon.

I have a W500 running Windows 7 which unexpectedly turns off, usually when asleep but sometimes also while on. The turn off happens as if the power is lost (say, the battery/AC cord are yanked out). After a turn off like that, I sometimes need to reconnect the battery and the AC cord. Did some reading here and elsewhere on the web and came upon the electrostatic suggestion. Was able to get it to turn back on at least a few times by touching the underside of the laptop, but that worked inconsistently.
Since it mostly happens when the unit is asleep, I pretty much ruled out the temperature and software issues.
Decided to check out the memory section pin bending solution. My laptop has to have it's palm rest taken off to access the RAM modules. People kept referring to some RAM door pins but since mine doesn't have a special RAM door, I bent some pins on the bottom of the palm rest and so far, not power loss but too early to tell.

I've got 2 separate but really annoying issues with my W540 20BH:
- display brightness keys not working: when waking up from Hibernation mode, sometimer (really, randomly!) the display brightness keys (Fn+F5/F6) don't work.... either if the display brightness is stuck on max, min or an intermediate level...Is there a way to shut down and restart the process which commands the Fn keys?
- audio channel commutation gets stuck. Normal behaviour of the audio configuration is:
1) speaker volume disabled, mic disabled
2) when plugging in a 4-pin headset, headset's volume is on, headset's mic is switched on; speaker volume is still disables.
3) when unplugging the headset, speakers' volume is still 0
After each boot, the audio channel is at 0, but doesn't commute to the headset when plugged in! I have to open Configuration Panel, realtek properties. With this window open, unplug and re-plug the headset. Now, the volume has its normal behaviour.
Any better way to configure audio channels and evenments, which is able to bypass realtek's manager?

I have a thinkpad l520 5016-c74 running windows 7 64bit and kubuntu 13.04.
When i try to adlust the brightness in kubuntu, the jotkeys work just fine.
On the other hand, in windows, i can adjust the brightness from the windows menu, but every time i hit Fn+home or delete (this is the hotkey on my machine) the brightness, regardless of where it is set, drops to 7 (from a scale of 1-15), and cannot be readjusted, If i hit again Fn+Home or Delete, it does this flash, like it's trying to change the brightness, but something holds it in 7. I can always change it from the windows menu. But again the same thing, hotkey and back to 7.

I just bought my laptop. Installed Windows 7 clean 64bit on it.This is the laptop's product page. I can't change the brightness of my laptop's screen. I can't do via the [Fn+Up/Down] combo nor by the Windows Power Options interface.
I tried all combos of installing and uninstalling the Lenovo Energy Management. (I got v7.0.4.1 on my laptop).I tried un and installing Intel HD 4000 (Driver v8.15.10.2696). I get Lenovo ACPIVPC v7.1.0.1 (12/15/2011) when installing the energy management thing.I've tried to install as least as possible other Lenovo crapware.

I will keep this short, I have a Lenovo ideapad y510p with Windows 8.1 (I got it with 8.1, did not upgrade from 8) . I noticed a problem yesterday, where I cannot adjust the screen brightness. If I use the keyboard commands (Fn + Up and Fn + Down) The slider appears on the top left of the screen, as always, but does not “slide” It stays static.
If I move the slider on the Setting menu, I can slide the value but the brightness does not change and the value is not reflected on the slider on the top left of the screen.
I am not sure when this happened for the first time.

I currently have an issue with my original X1 Carbon (2012, 3443-CTU) light not working on the LCD. I attached an external monitor to the laptop and it works without issues so it's not the motherboard. Under the right lighting conditions and angle, i can see very very faintly my desktop background.
This leads me to believe that the screen inverter is damaged, or the lcd. Since my ultrabook isn't under warranty, i believe the best course of action is to find the screen on ebay and replace it. [URL] ....
Is replacing the LCD as easy as it sounds? It looks like i need to remove much of the parts underneath the keyboard panel, and remove the LCD bezel and replace the screen. Is there something i'm missing?

I've got the 12inch thinkpad yoga. The left shift key works intermittently. This started happening to me a couple of weeks ago (I've had the computer since December and haven't noticed a problem. I sent it in twice and supposedly, they replaced the whole machine this last time, but I'm still having the problem. Could this be a fault in this model in general?

i recently bought my W520 and everything works just fine - except for the internal webcam.
I installed the drivers (current version) from the Lenovo web site but the webcam won't turn on. The green just wouldn't turn on and when I press Fn+F6 the communication tool shows up without any webcam video. Same thing for skype or any other webcam tool.
Sometimes after booting it works for a few seconds but then the image freezes and it won't start again until after several system restarts.
System Details:
Thinkpad W520 (4276), Core i7-2760QM
Windows 7 64 Bit Professional

Just installed Windows 8.1 Professional and tried to update all drivers via System Update. After that i installed latest Ericsson drivers (H5321 gw mobile broadband network adapter), and.... nothing! 3G is not working at all, because Windows says "Device cannot start. (code 10)" on MbmLowExt device.
SIM card installed correctly and working perfectly on my phones.

I just purchased a new 6-cell battery (44+) for my X230. When I install it and restart, I get the message "The battery installed is not supported by this system and will not charge." After starting Windows I can see that the battery is in fact not charging.
I tried to make sure to buy a 44+ battery that I was told was compatible with the X230.

I just received my Lenovo X1 Carbon; it's a very good product and I really like it. Everything is working as expected (fast & smooth) except one thing: laptop works kinda strange with the closed lid
My product code is 20A70037US, I'm running Windows 8.1 Pro.
I've chosen (in power options) that laptop does nothing when lid is closed. Yes, it works but... I'm using TeamViewer to connect to laptop; it works but TeamViewer periodically loses connection and displays message "The screen can't be captured at this moment..", Microsoft installer (I'm installing Visual Studio 2013) is paused (!), and Google Chrome won't render pages (but Internet Explorer works fine).
If I open the lid, all symptoms described above are disappear: installer resumes downloading, Chrome render html pages correctly and TeamViewer works fine (no periodical messages shown).
For me it looks like laptop not in "normal" operational state but kinda under power saving.
I've set power option to "High performance" (laptop is plugged) but it doesn't work.

Sometimes the machine does not show any wireless networks and I have been able to solve it by turning on and off the hardware switch for wireless on the back of the machine. This time I can not get the machine to find any wireless networks. I am running XP. The only think different that I noticed is that MS Security Essesntials has ended support for XP.

I might have seen the numeric keypad keys work once since getting this machine, but now can't get the keys to produce numbers. Some of the keys initiate other actions not associated with numeric data entry.
I tried removing the wireless dongle for my Microsoft wireless mouse but no improvement -- I simply swapped this MS mouse from my old W510 without doing any formal install.
This doesn't appear to be a hardware problem since the keypad keys have some effect -- just not the intended effect.

I have a new W540, and the microphone mute button does not work properly. When I press fn+f4. the red LED turns on, the slashed out microphone appears on the screen, and the volume settings for both the "Microphone" and "External Mic" are muted in Windows. However, audio from the microphones still capture audio, and it can be recorded on applications like Audacity and Skype.
Manually muting the microhphones via the Sound dialog in Windows has the same effect. The LED and OSD come on, but the microphone does not stop recording. As of now, I have found no way to mute the microphone outside of muting sound input in each individual applicaton.
