Lenovo Z500 touch brightness adjustment not working after Windows 10 update

Hi, i recently updated to Windows 10 and immediately noticed that the brightness of my laptop could not be adjusted. i had a similar problem when updating to Windows 8.1 but managed to solve it by downloading video drivers from the following link: http://support.lenovo.com/us/en/downloads/ds031547 I tried the same method to solve my current problem but it only works temporarily, as the next time i turn my laptop on, i have the same problem. Is anyone experiencing the same problem and has anyone found a permanent fix, because it's getting quite annoying. Thank you.

The intel HD graphics bundled with windows 10 seems to be buggy and in beta for now. so i guess we just have to wait for intel/microsoft to make a final release

Brightness Control not working after Windows 8 install...

Hi All,
I have a late year 2010 MBA core2duo with 4GB of ram, and I was running Windows 7 for a long time and recently bought a Windows 8 upgrade key. I heard the boot camp drivers were updated so I decided to load it up. I installed the new boot camp drivers on the Windows 7 side before the upgrade (had to use the command line to do the driver upgrade).
Windows 8 is all installed and the only issue I have is the brightness control doesnt work at all. I disabled the adaptive brightness as a lot of threads have been saying. Anybody have any ideas what I need to do to fix this?? It seems to be stuck on BRIGHT.

I have been having the issue of no brighness control when running windows through bootcamp for about 6 months now and have not found any applicable solution online.
While messing around trying to figure it out yet again I noticed that my monitor driver was signed by team viewer...
Sure enough clicking the roll driver back button resolved the issue by rolling the driver back to the Microsoft driver...
So long story short:
Right click "My Computer" click properties
Click device manager (lop left of window)
Expand Monitors section
Double Click monitor
Click driver tab
If the driver here is not signed by Microsot or Apple click the roll back button. My driver version is 6.1.7600.16385 (Driver date 6/21/2006)
Rolling this back instantly resolved my issue. I will now propagate this post to all the threads I saw regarding this issue.
I am running windows 7 x64 Ulti on a 15" rMBP.
Best of luck

HP G62 touchpad scroll not working after Windows 10 update

Hello, As many, I am having a problem with my touchpad scroll. It stopped working after upgrade to Windows 10. I have an HP G62 Laptop and the touchpad listed is Synaptics PS-2 port. Can you please provide information on how to fix? Best,

Hi there ,  Thank you for visiting the HP Support Forums and Welcome! This is a great site to get answers and ask questions. I have read your post on the HP Support Forums. I understand that your TouchPad is not working correctly since you upgraded to Windows 10.  I did some research and came up with a couple different documents that may help you with the TouchPad.
1. HP Notebook PCs - Using the TouchPad or ClickPad (Windows 10)). 2. Using and Troubleshooting the TouchPad or ClickPad (Windows 8): You can customize and adjust how you scroll using one finger or two fingers and how the TouchPad or ClickPad responds to gestures near the edge. Here is a link to the HP Support Assistant if you need it. Just download and run the application and it will help with the software and drivers on your system that need updating for Windows 10. The Windows 10 drivers will become available on the HP Drivers and Downloads Page for your product as they become available to HP. There are some drivers available there currently.  Have a great day!

Keyboard and touchpad not working after Windows 10 update

after udating windows 10 on my probook 4440s keyboard and touchpad not working. if i press a key for 10seconds the key then shows up in the screen. and touchpad is worst. it freezes all the time barely moves. but with usb mouse it works fine

It's known that installing Windows from an external DVD drive on a Mid 2013 MacBook Air causes that the keyboard doesn't work after finishing the installation. The fix is to install Windows by using a USB drive. See > http://support.apple.com/kb/TS4599

Touchscreen not working after windows 10 update.

Hello,I own an HP-Pavillion 15-n287cl touchscreen laptop. I updated my operating system today to windows 10, but after finishing the update my touchscreen dosen't seem to work. In fact it is not even reognized under the human interfaces tab in the device manager. I have tried intaling the HP drivers from the support assistant and the website but it still dosen't work. Any help on this would be much appreciated. regards.

It is not quite so simple.Windows 8.1 and Windows 10 do have native suport for touchscreens. There is the consideration that Windows 10 is a brand new OS. It has only been available to the general public for a single day. I am upgrading my current HP loaner HP Omen to Windows 10 Pro as I type this. I will know if the touchscreen works when it is complete. I am sure you don't completely rely on the touchscreen for input to the operating system. I only use the touchscreen once in agreat while if I even think about it. Wait for a few days and keep on trying the Windows update option. It will take some patience on your part. edit: The Windows 10 Pro update is complete. The touchscreen is still working just as it did before.

You can try reviewing the following site for drivers:HP Products - Where Do I Find Windows 10 Drivers and Software for My Model?

Once you are back to your original Operating System, check to see if you are experiencing the same issue.

Sony Viao inbuilt webcam not working after Windows 10 update

Hi thereJust updated to Windows 10 and now my inbuilt webcam is not working. Skype can't even recognise it.Under device manager it says there is a USB device with an error, but it doesn't say what it is. Disabling, uninstalling and restarting, and updating drivers do not work.I had windows 8 and 8.1 prior to this and the webcam worked fine. Please helpThanks in advanceMark

Hi mtaylor748,
Thank you for considering Sony Community!
Most probably the issue is with the Windows 10 driver since you mentioned the unit works with Windows 8 and 8.1. Unfortunately, we do not have the updated drivers for Windows 10 yet. Sony is still validating the updates from certain vendors and testing Vaio computers. You may check the announcement from Sony USA: http://esupport.sony.com/US/p/os10upgrade.pl? I'm note quite sure about the process in other country but feel free to contact Sony support in your location.
For further assistance, we kindly recommend visiting our Sony Global Web site for information on contacting the Sony Support Center in your region at http://www.sony.net/SonyInfo/Support/.
Hope this helps.
Best regards,
Vincent

Screen brightness keys not working after 5.0 update on Windows 8.

I believe the drivers for the screen aren't working since changing the brightness manually in windows isn't working either. There is also an error with the intel hd 4000 graphics, if that has anything to do with it. This problem did not occur before I downloaded the new drivers for windows 8.

Same thing is happening to me as well, just posted about it 30 seconds ago. PLEASE HELP

HP Probook 4440s WIFI Drivers Not Working After Windows 10 Update

I updated my Hp ProBook 4440s from windows 7 32 bit to Windows 10 32 bit, everything is working except for my WiFi it says 'Windows did not detect any networking hardware' Can you please provide me with the compatible wifi drivers for Windows 10 Pro 32 bit. I hope you can help

Hi: I guess what I meant to say is that you may want to play around with some of the advanced settings for the card in the device manager. It seems that reading the article you posted, that procedure may have been for folks that have Cisco software to allow for Virtual Private Networking (VPN) and I don't think the drivers you have include any Cisco extensions. You can see if there is Cisco networking software by going to the Programs menu in the control panel and see the list of programs installed. There are usually 2-3 Cisco networking software items listed if you do. Sometimes tweaking those advanced settings help. Here is an article that explains what some of these settings are for. http://superuser.com/questions/342759/can-somebody-explain-about-wi-fi-device-manager-settings-and-power-settings-in-w The ones I normally change are: Enable WMM. Set Roam tendency to conservative. Roam decision to optimize distance. I had to change some setting on an old Intel 5300 wireless card to allow it to connect in W10. The drivers were there, etc but when I went to connect to a network, it did nothing.
