Brightness Not Changing at all

Model: VPCS111FM Recently my harddrive failed and I replaced it with a new harddrive. Since I was starting from scratch, I had to re-dl the Sony drivers. Now, everything works fine on my laptop except the brightness. The FN keys work but no matter what I do the brightness does not change.. Things I have tried already:Going into Vaio Control Center and unticking automatic brightness. I can actually see the brightness bar in the Control Center moving, but my screen doesn't change.Going into Windows Mobility Center and changing the brightness. Nothing happens.Going into Power Options and changing the screen brightness bar on the bottom. Nothing happens. Not sure if this is related, but I was unable to dl and install Vaio Update.Also, I have an Intel Graphics card. I installed drivers for that too. Maybe it is conflicting with something? Any suggestions would be greatly appreciated!

Hi apshergill, It seems that you may have an issue with windows. Try reinstall the original video drivers and then installing the updates. If still not able to, then it could be a windows issue. May need to put the unit back to factory condition. Also you stated that FN + F5/F6 not working, does any of the other FN keys working? If not, then the notebook utilities not installed. Hi lobster131313, I have tested on our SVT jig unit here, there is not problem with the brightness. Please check FN function. If not working, reinstall Sony shared library and Sony Notebook Utilities and test again. Also download and reinstall video drivers and updates. Nick--Hi NicK, Only Brightness combinations FN + F5/F6 are not working, while other FN+ Combinations work well. That means Notebook utilities are installed. So what next?Regards

Hi,
When you set your monitor to a screen resolution that it won't support, the screen will go black for a few seconds while the monitor reverts back to the original resolution.
Regarding screen resolution, we may follow the below two articles to change it:
Change your screen resolution
Getting the best display on your monitor
Follow the steps below:
1. Open Screen Resolution by clicking the Start button, clicking
Control Panel, and then, under Appearance and Personalization, clicking Adjust screen resolution.
2.Click the drop-down list next to Resolution. Check for the resolution marked (recommended). This is your LCD monitor's native resolution—usually the highest resolution your monitor can support.
And if the monitor is LCD monitor, The monitor's manufacturer or reseller should also be able to tell you the native resolution for your LCD monitor. Or we may check the monitor's manual to adjust.

Screen brightness not changing after update to windows 10

Hello, After updating to windows 10, I am no longer able to adjust the screen brightness at all. It is stuck on the brightest setting at all times; which is inconvenient when I am on battery power and need it dimmed. The f2 and f3 buttons are not working to adjust the brightness, and I am unable to change it in power/power plan settings. I attempted to search for a possible missing driver that I had maybe lost upon updating, but there are yet no drivers for my product on the HP website for this purpose. Any help on this matter is extremely appreciated, as it is rather frustrating that I can't change my screen brightness. Thanks.

How about using the snipping tool to create an image of what you do see and posting it here. The snipping tool is what I used to create the image that I posted. What version of Windows 10 is installed? I upgraded to Windows 10 Pro on the Omen 15 and have the Enterprise version on one of my desktop systems. I have not yet used the HOme or Education versions, so I do not yet know which features they lack.

Screen brightness not changing

I recently formatted my system with windows 8 64-bit and after installing all the drivers, my screen brightness doesnt change

Hi GregA_154,
Try reinstalling your graphics drivers from your ProBook 4540s driver page. If that doesn't work then you have two options. You can try the Commercial Notebook forum because your model is a commercial product to see if anyone there has anything additional for you to try. The second option would be to contact HP. You can contact HP Total Care at 1-800-474-6836 in North America or start here if you live outside of North America.
Please click “Accept as Solution ” if you feel my post solved your issue.

Changing Apple ID does not change in all Apps

I recently (within the last year) changed my ISP and switched my email account. The old email was registered to my Apple ID and when I switched, I also changed the email to be my new Apple ID using "manage my apple id" online. This means that the Apple ID should be the same account, just a different name. There seemed to be no problems with this change on my iPhone and iTunes, but on my Macbook several applications are still looking for my old email for the Apple ID. These include iCloud and Messages.
I changed the Apple ID on my user in Users & Groups in System Preferences using the Change... option. I only have one user on the system and it is the Admin account. I can't find a way to change this in iCloud however. Messages isn't much of a problem, but more of an inconvenience. Every time I log in to my user account, the Messages dialog pops up asking me to sign in with the password to my Apple ID and displays the old one. I just cancel out of this. In the Messages application however, I have removed the old account and added the new one and I am able to send and receive messages using it.
Why are these apps still asking me for my old Apple ID when my Admin Apple ID is my new one?

Hi,
iCloud and the iMessages servers are effectively independent of the others.
You can in fact use different IDs for iTunes, iCloud and iMessages.
Start with System Preferences > iCloud.
There is no setting in here for enabling Messages (i.e. it has no links with any form account there).
Use the Sign Out button to disable the current Apple ID and then add the new one.
Do the same in Messages > Preferences > Accounts for the iMessages account.
As you have Mountain Lion use the Details Button then the Sign Out one in the next pane.
I have two of my several Apple IDs listed in th Users and Groups pane but it also is deactivated as regard to changing password resets.
You can alos use an Apple issued email ID as A Valid AIM screen name in Messages (Add under AIM/AOL depending on version)
This means @mac.com and iCloud issued @me.com and @icloud.com can be used as AIM Screen Names.
This may mean you can have it as the iMessages ID and as a Screen name.

Auto brightness not working in ios6

I updated my iPad (3rd gen) to ios6, but when the update is complete i found that the auto brightness not working, when i use the ipad on dark room the brightness not changing, when i use ios5.1 it changing.. Any solution and actually the problem is on ios or in the hardware? Looking for help asap...

Well my device is different and since it is a iPhone 5, it is not being updated to iOS 6 but the issue is exactly the same. From my mind this could be up to software but also could be from an hardware issue. The thing is that even if it worked before iOS 6 for you the new software could have revealed hardware conflicts since the software interacts different with the hardware for some features. This would be the worst case scenario because I know that normally iPhone 4 devices if not the 8GB model will be out of warranty. For me this is just a small issue since my warranty is still one year :(
I have contacted apple care for this issue and have get the info that it will be escalated to the engineering team, for further investigation. As I know there was also an issue with some proximity sensors at the beginning if the iPhone 4 models and I think there was an software fix for a lot of them. Hope for the best!!!
I have also done a lot of Troubleshooting, reseted settings, content and settings, restored in dfu and recovery mode, restored with new .ipsw (iPhone OS), restored on different pc (so even this step gas downloaded a totally new .ipsw file), first on a Mac!
Next step wis that I will let the battery drain low entirely, a Troubleshooting idea of an friend. This might empower the entire hardware for a restart. I am not really believing in this step but I will give it a try :)

Free Space on Time Capsule not Changing

I've noticed this problem over the last couple of weeks. The amount of free space (and used space) on the Time Capsule drive is not changing. All the backups are happening as they should, but no change in free space.
I've verified all the backups are there by entering time machine and seeing the files for all dates.
I checked that it wasn't just a coincidence based on backups and then removal of old ones (thinning) by looking through the system log and it shows that after every backup and ever pre/post-thinning it always shows 803.7 GB free (actually, exactly 803.65)
I tried restarting my coputer.
I tried restarting the Time Capsule.
I upgraded the Time Capsule firmware to the latest version (7.3.2).
All without luck. Has anyone else seen this behavior or have any idea what might be going on?

Here's an example from some recent backups. This is the System.log records relating to backupd.

Virtual key figure BADI - does not change value

I wrote a badi for virtual key figure according to guidelines from an SDN doc on how to create virtual chars and kf's.
However, the value of the key figure is not changed at all. Below is my code. Please see what I'm doing wrong
method IF_EX_RSR_OLAP_BADI~DEFINE.
   APPEND 'ZRANKS' TO c_t_kyfnm.
endmethod.
method IF_EX_RSR_OLAP_BADI~COMPUTE.
if P_KYF_ZRANKS > 0.
    assign component p_kyf_zranks of structure c_s_data
    to <fs_ranks>.
    <fs_ranks> = '1.0'.
endif.
endmethod.

There is something you need to do which I have not seen described in any of the documention here.
You need to copy the source code for the INITIALIZE method directly from the code given in the example class CL_EXM_IM_RSR_OLAP_BAPI. That is where the P_KYF<object> and P_CHA<object> attributes are assigned their values. If you do not copy this code into your own implementation, these attributes have no value in the COMPUTE method and your code will probably not work.

Is there a way to adjust shadows in iMovie 11? WhenI adjust brightness it changes shadows also. If not is there free or low cost software available? My operating system is Lion.

You used the data. Verizon can not see what it was sued for. However your phone can see whats apps used the data. go to settings-data usage- there will be a place that says data usage cycle. line the dates up with your cycle. then there will be a bar graph below that extend bother white bars one all the way to the left and one all the way to the right. after those are extended below that will be a list of apps, there should be one that used over 2 gb and that will show you what app used that data in her purse

I created a slide show in imovie for my daughters 21st with voice overs from friends and family which was all working fine but now the voice recordings are not playing at all. Obviously some setting has changed but I can't find which one.

Email will not let me change fonts all of a sudden.

Email will not let me change fonts all of a sudden. It says I don't have the neccesay permissions in ~/library/preferences. this has just happened recently.

Who is your email provider?
You can try resetting your iPad by simultaneously pressing and holding the Home and Sleep/Wake buttons until you see the Apple Logo. This can take up to 15 seconds so be patient and don't release the buttons until the logo appears. Try again to see if the problem persists.
If yes, try deleting the mail account and adding it again.

I have an Iphone 4s from my work. Until 2 days ago, my iphone would notify me when I got an email or text. Now it does not notify me at all and some times it does not ring at all either. I have not changed any settings at all.

My iphone just randomly stopped notifying me when I got an email, text or voicemail. Sometimes it will not even ring. I confirmed that the volume is turned on and I have not changed any settings at all. My software is up to date. In my job I need to know when I get an email without having to constantly activate the screen or open the email icon.
Does anyone have any suggestions to fix this problem?

First, is the Mute switch activated?
Mute switch is above the volume buttons on the left side of iPhone.
If you see red/orange color the the mute is ON.
Also check Settings > Sounds > for New mail, Text Tone, etc.. have sound entries?
If that's not the case try
Reset: Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears. Note: You will not lose any data
