Can not adjust brightness and minimize and maximize the screen with Fn keys

I have bought a HP 15-D006TU laptop 1 week back. f2 and f3 for adjusting brightness and f4 to minimize and maximize the screen are not working. I am also trying to install the Hotkey driver which is mostly suggested here. but the version available is not supported. Can anyone help me out in this case?

Hi NIdisha,
Thank you for your post, I will do my best to assist you.
I understand that you are experiencing an issue with the brightness and the fn keys. When I looked up the specifications, I see it came with FreeDos. I am providing you links, to the software and driver page for your computer,HP 15-d006tu Notebook PC Drivers and Frequently Asked Questions About FreeDOS (FAQs). Please note the compatible keyboard driver. I would suggest you uninstall and reinstall the drivers for the keyboard. I am also providing you a document on Notebook Keyboard Troubleshooting (Windows 8), that may assist you. If you would like furhter assistance, please let me know if you are still running FreeDos, or have changed the operating system.
I hope this has helped.

I recently did the latest update. My Ipad 2 would not turn on, and then the screen with the apple logo started flashing. I tried the recovery restore, but I kept getting error messages. What should I do?

I recently did the latest update, and then I charged my Ipad 2 afterwards. I went to use my Ipad 2 days later, and it would not even turn on. Then after a couple minutes, the apple logo appeared as if it were loading. It continued to do this for a few minutes, and then the screen starting turning on and off. Then 5 minutes after that, my lock screen appeard and froze. Then it shut itself off again. I tried plugging my ipad into Itunes to do the recovery restore, but I kept getting error messages.

The strengthood for Apple for the fourthfullness to be legal, which I respect, can become too restrictive in my European eyes. Any hearing around? René

Thanks for the information. It seems that you have installed an OS version higher than the one supported by your carrier on your device. Please contact your carrier to get the supported OS version and try the proximity and light sensors. Let us know if you need further assistance. Cheers. ^LFC.

Lenovo z570 and Fedora 15 - can not adjust brightness.

When I installed fedora 15 on lenovo ideapad z570 all goes ok. but I can not adjust screen brightness. I updated kernel twice upto 3.0.1 but still problem persists.
Please give me a solution.
CPKulkarni

This is a known bug in the power manager logic within fedora 15. They are testing the package before it makes officially to the repository.
If you want to try it, out run the following command in the bash shell
su -c 'yum --enablerepo=updates-testing update gnome-power-manager'
Also try to disable screen dimming via the control center. Hope this helps you out

Can not re-size and move on screen keyboard on windows motion tablet

I have some Tablets (Motion F5) they all have windows 7 pro installed.
After a few windows updates last week the on screen keyboard (standard integrated) i cant customize the size anymore. also i cant move it to where i want on the screen. in the settings you can choose between:
- Pin to the bottom of the screen
- pin to the top of the screen
-floating
the last one is checked.
after i restored windows to a restore point a few days back it works again.
now one day further and it crashes again.
when i search in the start menu for on screen keyboard i found an similar keyboard. that one still works.
anyone any idea what exactly occurs this, and how i can fix this without ignore the windows update's?
Ps. this problem occurs on all tablets we have (5 pieces). :-(
thanks,

Hi,
This issue can be caused by corrupted system files during update installation or incompatible update.
Please first try following suggestions:
1. Update your keyboard driver in Device manager.
2. Run command SFC /SCANNOW as admin, any error, post back the cbs.log.
3. Run this command to repair Windows:
dism /online /cleanup-image /restorehealth
If there's no changes on this issue, please restore your system back to the point when the Keyboard work fine, and manually install checked out updates one-by-one, after each one, please restart computer to check the issue.
Then let me know which update cause this issue.

How can I make an image (gif) go over the screen with javascript?

Hello,
I'm working on a website for an archery club. Everything works great but I want an arrow going from one side to the other on a certain moment.
I cannot find a script that works like I want. The image should start out of the screen and has to leave on the other side with a certain speed.
I'm not able to write such a script myself. I'm not certain how or when it should start but I can fix that in the script I guess.
Thanks for any help,
Regards,
Theo

How can I make my footer full width of the screen with a fluid grid layout in CSS?

Any Ideas?
#footer {
clear: both;
color: #FFFFFF;
min-width: 100%; // I have tried max-width and width as well.
margin-right: 0px;
margin-left: 0px;
background-repeat: repeat-x;
background-image: url(/images/footer.jpg);
I know it is being over-ridden by
.gridContainer {
width: 88.5%;
max-width: 1232px;
padding-left: 0.75%;
padding-right: 0.75%;
margin: auto;
clear: none;
float: none;

Move your <footer> tag below the closing .gridContainer </div> tag.

Adjusting brightness and colour temperature on WindowXP PC

Hi,
I'm using Windows XP PC. I just bought 27" Cinema Display but I find that i can't adjust brightness and colour temperature in Windows XP......
I'm new user for apple and feel confuse about how to use this cinema display well in Windows XP PC.
Many thanks
Ben

For brightness you need the AppleControlPanel.exe file from the Boot Camp package to be able to adjust the brightness - don't install the whole of Boot Camp as it will cause problems on a non-Apple PC, just get this one file - I can provide it if you can't find it elsewhere.

PlayBook lags and then the screen goes black and does not respond

Hello guys,
As the Subject line summarizes, my tablet was working like charm since the date of purchase, back then in April last year. However, on these days it has been performing weird. It has always been fast and smooth, but since last week it has been lagging and not no responsive to the touch.
To tell you gusy fast and clear, it boots up as normal, fast and smooth, apps open and close as usual. Then it starts to lag, and freezes for one second, responds and freezes again but this time will not respond again and finally the screen goes black and stucks there until I make a hard reset and it reboots normally, until it does it again, and again.
Relevant information:
16GB model, 1.5GB free storage available, sideloaded a few android apps today, recorded a few videos
the device manager software on the pc makes no difference, as the PB will anyway freeze and go all black even if it's backing up or something.
HELP?

Make sure any important data is backed up preferably by drag and drop to a pc.
When it is working properly, try gently squeezing the playbook between finger and tbumb around the black bezel border. Especially either side of the lower sockets. If it goes black it's probably a bad battery or screen contact.
1.5 GB is not much spare storage, by the way. I would never fill more than 75%.

I am trying to use the brightness adjustment on a grayscale photoshop CS6 file. The preview shows the adjustment working and changes the brightness, but when you click to apply the change, it does not apply the adjustment. I have run into this problem before, although rarely, with some other files over the years and with earlier versions of CS. I would like to know how to overcome this problem?

Make sure you are viewing your image at 100%. At smaller views, pixels and layers and the way they interact are approximate interpolations and won't show you the actual pixel-for-pixel changes.
