Lenovo ThinkPad L R/SL :: L520 - Can't Adjust Brightness
Jan 10, 2013
Another problem on my Lenovo Thinkpad L520: After installing the Lenovo Power Management Driver, I can no longer adjust the LCD brightness by using the FN+DEL/POS1 keys. Immediately after adjusting the brightness, it gets reverted to its old value, set in the Power Management software.
I tried the Windows 7 driver (1.65.05.21) and the WIndows XP/7/8 driver (1.66.0.22), both with the same result.
This is really annoying and I am very frustrated with Lenovo right now, since this is not the only problem I am having with the laptop.

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 have a W540 with 3K Ips panel and Windows 7 Pro 64bit.
I recently installed a new hard drive and installed windows 7 pro 64 (previously on the other hard drive was Windows 8.1 Pro 64 bit ( there I could change the brightness ) )
My problem is that I can not change the brightness .
I've already tried:
-Reinstalled all NVIDIA driver
-Reinstalled all Intel graphic drivers new
-Reinstalled Intel and Nvidia drivers simultaneously
-Remove Lenovo Power management
-Tried to install NVIDIA driver from the Lenovo and the Nvidia page
-Reinstalled Windows

There isn't a print screen button on my new L520, know of any key combinations that do the job? or do you have to use the Win 7 snipping tool?

The most critical issue on my week old L520 is that it goes into sleep mode seemingly randomly even while I'm doing work. (In fact, it went into sleep mode twice while writing this post.)
I have the newest (3.59) Power Management Installed with all settings set to keep the system awake, plus updated drivers for both Lenovo and Microsoft via the Think Vantage Toolbox update feature.
According to TP Fan Control the temperatures seem fine, except perhaps for the 6th and 8th sensor, where the temperature always hovers around 60c or a little below. [URL]...

I have updated some months ago, my laptop 7859-5SG from Windows 7 to Windows 8 -> 8.1 and after that the bluetooth radio doesn't work anymore.
I tried to find a driver on the driver download section for my laptop, but I didn't find nothing. First problem found, is the hotkey fn+F5 that not show nothing on the display after key press, and normally with this function I can see if the radio is on or off.
I checked on the BIOS section if bluetooth is enable, and this is on. What I can do to activate bluetooth radio again?

I've had my L520 for over a year now and have not previously needed to burn stuff to disk, so I do not know if my problem is new or old.
Essentially the drive recognises disks when they are inserted and accurately displays files already on the disk, but it gives available space as nil regardless of disk or existing file size. Additionally if a blank disk is inserted it will say that the disk cannot be read and to try formatting. These are standard preformatted disks I'm using.

I want to install a new ssd-drive, which is empty. I did create a DVD under rescue & recovery. But on startup with the new hdd, it only offers me a restore option, not a NEW system. R&R also only created ONE disc, imho thats not enough, dont I need some more for the whole system?
And I cant backup the whole windows system, because even though its fresh its 80 gig (some data was taken along, dunno which)...
And thats my problem in a nutshell: I cant create discs with ONLY the windows install-system, or rather I dont know how
I now tried 3 times, and R&R burns only ONE disc, and booting from that, it asks for a recovery. I want a new fresh virgin system...
I tried a couple of times, did not work. Had to swap back the old drive to work again.
System: Windows 7 professional
Lenovo L520

I used my brightness down button once and now it won't go back up. I can't adjust the settings at all, despite the graphic on the screen showing me the meter going up and down. I've checked all drivers, tried uninstalling and reinstalling lenovo energy management, and I've still got nothing. I've stopped short of a factory reset because that's super annoying having set everything up and then a couple weeks after purchase have to do it again.

I can't adjust my screen brightness using the Power Manager. Updating to the latest release of the ThinkVantage Communications Utility did not solve the issue. I can't make the screen either brighter or dimmer.

I open this post to report a brightness problem on Lenovo Z500 Ideapad. Yesterday I've upgraded to OS Windows 8.1 and when I adjusted the screen brightness it goes off, and brightness adjust function doesn't works. I've solved my problem reinstalling the Intel video drivers, downloaded from Lenovo Driver Support.
It seems that Windows 8.1 upgrade disables video drivers.

For some reason the brightness on my lcd isn't adjustable. It's stuck at full brightness, on battery, on power, doesn't matter. I've had this laptop for about 2 weeks now. When I first got it, the brightness levels were working, but now they are not. OS is Windows 7 Home.
FN - Brightness Down brings up a on screen display showing the brightness level at full and goes down by about 1, though I see no different in the brightness. It doesn't matter how many times I press the button, it never goes down more than 1.
Control Panel -> Display -> Adjust Brightness -> Power Options: The slider at the bottom shows the brightness level at lowest setting. The FN - Brightness adjustment will move this slider up / down on the scale, but there is no change in the screen brightness.
Anyone have any ideas as to why I can not adjust the brightness and how I can get it back to where I can adjust it?

I just installed Win7, sticking as much as possible to this method:
VAIO FW Clean Windows 7 Install Guide
everything's working, all FN keys, volume multimedia zoom LCD out,
all but brightness.
problem is, using the FN keys, the brightness dialog is showing, but I can't increase or decrease it. brightness does not show up on power managment nor on mobilty center. the power plans from vaio ("VAIO optimized") are showing, but still if I pull the plug screen stays on maximum brightness...

I have a HP Envy dv7 Notebook PC. It recently just downloaded the new HP Assistant and I wanted to adjust the brightness because it was too bright for the dark room I was in. I tried using the F2 and F3 keys to lower the brightness and I tried to adjust it from settings and control panal but the brightness doesn't adjust when I move it up or down. I tried shutting down my computer and restarting it but I still can't adjust the brightness.

I have very annoying problem with hot keys for adjusting monitor brightness! After last version of hot keys driver they don't work. I can't increase or decrease brightness! Pressing them down and can't change anything. And there is something more! For example I have adjusted some level from power manager and everything looks good until I don't try to manage brightness with hot keys. I doesn't matter if i want to increase or decrease brightness, it just goes to maximum level!

I have the Lenovo L440 (20AT002YGE) with the integrated Intel Graphics.
I have turned off the automatic dimming of the screen brightnes in the windows energy settings and also turned off the energy saver settings in the Intel driver but the screen keeps beeing dimmed when the background is black or dark. This is very annoying when you work outdoor and the sun keeps shining on your display and than it dimms the brightness.

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.
