OPTION to adjust display brightness on nokia asha ...

Hi NOKIA Representative,
Please provide the support and option to adjust display brightness on NOKIA ASHA 200 in the next software update. (I have NOKIA 200 V11.56 showing manfacturing date 26-03-12).
Adjustment of display brightness is very basic and important feature in any phone, how come NOKIA forgot it in this model (NOKIA ASHA 200) ??
Thanks,
Raven777

The manual display brightness option should be added to the device in the 11.81 (or newer) SW updates - so try updating your phone SW.

Cannot adjust display brightness via F-keys nor Preferences

After updating Mavericks to 10.9.4, I cannot adjust the display brightness. Using the F1-2 keys will show the brightness icon that usually pops up. However, it's stuck and nothing happens when I press either F1 or F2 (the brightness keys).
I tried going into Preferences and adjust the brightness from there. "Automatically adjust brightness" is not checked and when I drag the slider, it slides back to where it initially was.
How can I fix this problem?
Thank you in advance,
Filip

Hello Gnazty,
Thanks for using Apple Support Communities.
I'd like you to reset your SMC and PRAM as the articles below describe:
OS X Mavericks: Reset your computer’s PRAM

Automatically adjust display brightness via Terminal / Pretty good solution

This hint is for all of you who experience any problem with the adjustment of the display brightness.
*Short version*
After a cold and/or warm start, it sometimes happens that the brightness was changed by the system itself to its dim power saver setting or maximum value and sometimes - what a big surprise - remains as it has been configured.
I had spotted plenty of articles about this phenomenon, but none of them yielded a solution. I then decided to solve this problem by going the pragmatically way and use some kind of software which dims the display to my preferred setting. And the winner is: brightness.
This tiny program works perfect and you will love its benefit by using it in terminal - yes, brightness is a command line utility. On top of this, brightness is able to control different displays, internal and external. The clou: beside using the precompiled binary you can also download the source code here, modify it to make the program fit your needs and then compile it using Xcode.
1. Installation
Download a precompiled version of the command line utility brightness here and extract the binary to your desired path (e.g. /usr/bin).
2. Usage
"brightness -l -v" dumps the current display attributes (-v for verbose mode) while "brightness 0.5" modifies the brightness of the main display to half of its max value and "brightness -m 1 1" let a second display become shiny. Just play little bit around.
3. Automatically launch
Simply create a .plist file and drop it, for example, in ~/Library/LaunchAgents. Or make use of an AppleScript or a Terminal Script to let it launch.
That's it. Comments are welcome.
*Long version*
It seems to be, that the adjustment of the display brightness of an iMac and MacBook/Pro (maybe also other models are affected) drives a life of its own. After a cold and/or warm start, it sometimes happens that the brightness was changed by the system itself to its dim power saver setting or maximum value and sometimes - what a big surprise - remains as it has been configured.
I had spotted plenty of articles about this phenomenon, but only found terms like "Did you already disabled the ambient light sensor", "Did you already reset the PRAM?", "Did you already reset the NVRAM?", "Did you already…BLAH". Far from it, all of these tips have one thing in common: none of them yielded a solution. As a last resort, I thought, it was a good idea to install 10.6 from the scratch just to find out that the above mentioned phenomenon occurs right after a few days of using OS X.
I then decided to solve this problem by going the pragmatically way and use some kind of software which dims the display to my preferred setting. There are a few applications to do this, but always it was necessary to drag a slider or type in a value to dim the display, so none of them allowed an automatic configuration. No, I am not a very sophisticated person, I only prefer to use software which is simply well-thought-out. And the winner is: brightness.
This tiny program works perfect and you will love its benefit by using it in terminal - yes, brightness is a command line utility.

3. Automatically launch
Sure, OS X provides different ways to launch a program automatically. If you are an enthusiast, feel free to use the one you prefer and stop reading, because you are already finished. If you are not that familiar to OS X take the next step as an advice.
An easy way to trigger OS X launching a program automatically is to add the desired program to your Login Items. But, in this case, it will not work the easy way, because we have to launch a so called classic command line utility with a given option. It is not like starting Mail or iCal, which appears as typical applications to OS X. You must start brightness via Terminal by typing "brightness 0.5" (without quotes) to modify the main display brightness to half of its max.
We now use a Launch Agent. Just create a .plist file, e.g. com.brightness.plist, with your favorite text editor. For the lazy ones here comes the template (simply copy and paste):
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Disabled</key>
<false/>
<key>Label</key>
<string>com.brightness</string>
<key>ProgramArguments</key>
<array>
<string>/usr/bin/brightness</string>
<string>.5</string>
</array>
<key>RunAtLoad</key>
<true/>
</dict>
</plist>
Save the file in ~/Library/LaunchAgents, if you want brightness to be executed everytime you log in.
You could also use an AppleScript. Copy and paste this code "do shell script "brightness 0.5"" (without the leading and closing quotes) to a new Script. Then choose Save As and enable the Option to make it Execute only. Now add the Script to your Login Items.
Another option is to use a Terminal Script. Copy and paste this code
#!/bin/bash
/usr/bin/brightness 0.5
exit 0
and save it as, for example, brightness.sh. Make the Script executeable and add it to your Login Items.
That's it. Comments are welcome.

Thanks. Works great. I made a ScriptBundle and a User Agent (launchd) . So if someone sets the display brightness to maximum, it automaticaly corrects it at next login.
The ScriptBundle contains your mentoined command line utility and the following applescript:
do shell script quoted form of (POSIX path of (path to resource "brightness")) & " 0.7"
Be aware of the space in " 0.7" or whatever value you have set.

(SOLVED) Display brightness disappeared from Power Options in Vista, Lenovo G530

Hello board,
My system Lenovo G530 product ID 444638U
I used to be able to adjust display brightness in Vista from Control Panel > Power Options. I could set how bright when on battery and how bright when on AC. Also, it used to be that when I unplugged power cable it would automatically adjust my brightness according to those settings. Now, nothing happens when I unplug power cable, not even a beep.
Possible problem is as follows, but let's keep an open mind to other things as well. I spilled beer on keyboard recently. ONLY on keyboard I am sure. I replaced keyboard with something that fits but something that isn't made for my laptop, has different arrangement of Fn+ keys. Basically ever since the beer accident and ever since I replaced keyboard I had this brightness issue.
Please help me solve this.
-Alex
Solved!
Go to Solution.

I solved this problem..
Solution is to upgrade the BIOS to latest version. I am not sure actually whether latest BIOS had the needed fix or not, or it was just the process of updating the BIOS that solved this issue. But no doubt, after flashing the BIOS, display brightness function reappeared!

HT3924 Adjusting the brightness doesn't work

This article states "Use the keyboard of the iMac in TDM to adjust display brightness" but this does nothing. It can adjust the sound but the brightness keys don't do anything. The display stays at full brightness.
Does anyone have any ideas?

I figured it out! You can only adjust the brightness if you are logged in on the iMac. So you have to unplug the external card or MacBook, log in, then plug it back in. Then you can adjust the brightness until the screen saver comes on...

How do you adjust the brightness on a Thunderbolt Display

How do you adjust the brightness of a Thunderbolt Display attached to an iMac ?

I had this peculiar ‘issue’ hooking up to my MacBook Retina when my Thunderbolt Display was delivered but Applecare - thanks Andrew - got me there. It seems daft!
The Thunderbolt Display Brightness slider IS there – you just have to know how to make it show up.
At initial set-up of the Thunderbolt Display [or if the Brightness slider is ever not visible in the System Preferences> Thunderbolt Display window], so long as the Thunderbolt [external] Display and the Macbook Display are ‘mirrored’ I can control the Thunderbolt [external] Display via my MacBook Retina Brightness keys [F1 & F2] – or by the Brightness slider that THEN appears in my System Preferences>Thunderbolt Display window. Once set up the Thunderbolt Display System Preferences Window continues to show the Brightness slider but I occasionally lose it if my MacBook has been disconnected from the Thunderbolt Display for some time – and I then have to start over.
So:-
Apple menu >
System Preferences>
Displays>
Click Arrangement [at the top]
Click Mirror Displays [at the lower left]
That then gives me-at-least a Brightness slider on the System Preferences> Thunderbolt Display window [as well as on the Built In Retina Display window] and I can then adjust them independently.
Oddly, having set this up just once the Brightness slider then remains on my Thurnderbolt Display and I can control it [and my MacBook Retina Display independently]. Occasionally I lose it again and have to start over.
Hope this works for others.

The display brightness can't be adjusted in Windows 7 under Bootcamp 4, iMac 21.5 (mid 2011) with ATI Radion 6770M..

The display brightness of my iMac 21.5 (mid 2011, with ATI Radeon 6770M) can't be adjusted in Windows 7 installed under Bootcamp 4. I tried moving the brightness glider either with apple keyboard hotkeys (on-screen glider), or within Windows control panel brightness control (within the power option), but the brightness remains the same. I've had all software (Lion, bootcamp, windows 7) up to date. Please help. Thanks.

I posted a similar case to yours a month ago and it seems we're in a minority on the problem. What I have learned over this month was that Bootcamp drivers version 4 (Designed around OS Lion) was a BIG part of my issue with the ATI video. The new IMacs seems to require a customized by Apple Verion 3.2 or 3.3 to operate normally. Sadly, it's not as easy as just backing off version 4 and going onto 3.2 and getting the video slider back. You need to reload Windows and avoid Bootcamp 4.0 as it seems a piece of V4 gets stuck in Windows. I'm putting this suggestion to practise this week, guess I'll have more to say later.

In my HELP section on my computer it tells me to...
Tap or click PC and devices, then tap or click Display
Make sure the Adjust my screen brightness automatically slider is turned on
Get the best display on your monitor - Microsoft Windows Help
(If you don't want the screen brightness to change automatically, tap or click the Adjust my screen brightness automatically slider to turn it off.)
Tap or click Apply.
I do not have that.
I notice that if I go to the side of my screen and then click on Devices, click on projects... "Second Screen" is showning
I clicked on it and then I went and clicked on PC screen only and it is highlighted, but when I go back to it, it stills shows "Second Sreen"

How can I adjust the brightness of my old Apple 24" LED Display?

How can I adjust the brightness of my old Apple 24" LED Display?

Jacob,
Thank you for the quick response. I opened both the TIFF and the EPS in Illustrator. I used the Eyedropper tool to get the CMYK values of the color of the text part in the TIFF, then I went back to the EPS and selected the text and input the CMYK values in the color tab. I know it's not precise, but it's close enough. Could I have done this better?
Yes, I have access to Photoshop but I haven't tried using it with vector files. I am really new to graphic design and I need all the help I can get. Thank you!

MacBook display brightness will not adjust

My MacBook display brightness is very low level, the F1 and F2 brightness keys bring up the transparent window and show brightness turned all the way down, but F2 does not increase the brightness. In Preferences, the display section shows the Brightness slider all the way to the top, and if I attempt to slide that down it snaps back to the top, and the actual screen brightness does not change from very low. I also have verified that the function keys are NOT set to lock out the brightness function, so pressing command and F1/F2 does nothing. So nothing from previous forums seems to apply! All other function keys operate properly (multi-window, volume, dashboard).

OK guys, think I found a solution to this one.
My girlfriend's mac had the same problem as yours, and I was motivated to fix it becuase I needed to use my mac for my dissertation and she kept stealing it!
anyway, turn the brightness all the way down, press it up once and you will see the screen flash. do it again, really fast up and down up and down and the scree will stay on as long as you keep playing with the buttons.
next, use this temporary fix to get into system preferences -> displays... and change the resolution to something considerably lower. then it stays on permanently. Not too sure about why this happens, maybe the mac can no longer handle that many colours or complexities?
sod it. enjoy.

My display is dull, how do I adjust the brightness?

I have an iMac, the screen has gone quite dark (as if in sleep mode) I have to sit in a darkened room to see it properly. Have I hit the wrong key or key combination of keys? How do I adjust the brightness? Help

If you are still on 10.4.11 (stongly doubt it) you probably have wired keyboard, the F3 key is for brightness. Also check System Preferences - Universal Access - Seeing and check there too.

Laptop-mode-tools no longer adjusts LCD brightness

I just discovered that laptop-mode-tools no longer adjusts the brightness of the LCD when switched to battery. This is not a general issue. laptop-mode is active on battery (as well as being enabled via the systemd service), the computer knows it is on battery (checking with on_ac_power and reading from /sys/class/power_supply/*/* give the expected results) and other things are correctly adjusted e.g. bluetooth is blocked with rfkill. Moreover, as root I can adjust the brightness in the usual way by hand:
echo 10 >| /sys/class/backlight/acpi_video0/brightness
works just fine. The >| is needed because for interactive shell's, root's .bashrc sets noclobber. This obviously doesn't affect laptop-mode tools because it doesn't run an interactive shell. In contrast:
$ cat /etc/laptop-mode/conf.d/lcd-brightness.conf | grep -v "^#"
DEBUG=1
CONTROL_BRIGHTNESS=1
BATT_BRIGHTNESS_COMMAND="echo 7"
LM_AC_BRIGHTNESS_COMMAND="echo 10"
NOLM_AC_BRIGHTNESS_COMMAND="echo 12"
BRIGHTNESS_OUTPUT="/sys/class/backlight/acpi_video0/brightness"
DEBUG wasn't 1 when the problem started. I tried setting it to get more info but haven't found anything more in the journal/logs.
KDE is set to not touch the default brightness at all. All it does is (further) dim the display after so many minutes depending on the power supply and status.
This did work fine but I haven't been on battery for a while so I'm not sure when exactly it stopped working. My brightness is set by default to 12 on boot or wake from sleep which suggests laptop-mode tools does something or something else is now handling this which I'm not aware of. But the switch to battery does not trigger any alteration in the brightness and laptop-mode status does not even mention LCD brightness as one of the things laptop-mode tools controls.
Have I missed a change in how this is handled somewhere?

I doubt this is related but it is currently my only lead so here goes. I set the LCD brightness control for debug so I've been trying to watch it. However, so far it is all smiles e.g. on boot it all works fine and says so.
However, I found I'm getting another error on boot which is
/usr/share/laptop-mode-tools/modules/pcie-aspm: line 10: write error: Operation not permitted
Note that I copied that by eye from VT1 so if a colon is out of place, that's why.
The contents of that file is:
#! /bin/sh
# Laptop mode tools module: PCIe Active State Power Management
if [ x$CONTROL_PCIE_ASPM = x1 ] || [ x$ENABLE_AUTO_MODULES = x1 -a x$CONTROL_PCIE_ASPM = xauto ]; then
if [ $ON_AC -eq 1 ]; then
log "VERBOSE" "On AC power: setting pcie_aspm to default"
if [ -f /sys/module/pcie_aspm/parameters/policy ]; then
echo default > /sys/module/pcie_aspm/parameters/policy
if [ $? -eq 0 ]; then
log "VERBOSE" "PCIe ASPM set to 'default'"
else
log "VERBOSE" "PCIe ASPM tweaking is prohibited by the kernel"
fi
else
log "VERBOSE" "PCIe ASPM is not available"
fi
else
log "VERBOSE" "On battery: setting pcie_aspm to powersave"
if [ -f /sys/module/pcie_aspm/parameters/policy ]; then
echo powersave > /sys/module/pcie_aspm/parameters/policy
if [ $? -eq 0 ]; then
log "VERBOSE" "PCIe ASPM set to 'powersave'"
else
log "VERBOSE" "PCIe ASPM tweaking is prohibited by the kernel"
fi
else
log "VERBOSE" "PCIe ASPM is not available"
fi
fi
else
log "VERBOSE" "PCIe ASPM power savings module is disabled"
fi
So I assume it is saying it cannot write to /sys/module/pcie_aspm/parameters/policy but the permissions etc. on that, at least, don't look strange:
l /sys/module/pcie_aspm/parameters/
total 0
drwxr-xr-x 2 root root 0 Gor 25 21:24 ./
drwxr-xr-x 3 root root 0 Gor 25 21:23 ../
-rw-r--r-- 1 root root 4.0K Gor 25 21:24 policy
