U400 Touchpad not disabling after Windows 8 consumer preview installation

The u400 touchpad used to disable when i pressed the f6 key. However, once i installed the Windows 8 consumer preview, the touchpad stopped disabling. I installed the newest driver (the one released Feb 8) and still have no luck. They funny thing is, when i press f6, a sign appears on the lower right corner that shows a disabled touchpad (touchpad with a line across it). However, the touchpad still functions.
This is a pretty big issue for me since I find it nearly impossible to type comfortably without the touchpad being disabled. (For example, my cursor jumped 5 times when typing this post) I am sure I am not the only one with this problem. Please help! Worse comes to worst, i will reinstall windows 7, but if there is anyway to fix this problem, please let me know.

I didn't have exactly this issue but wanted to permanently disable but that was not going to be easy. Mine was hypersensitive and totally messed up any keyboard work. I called tech support and they installed new software to lessen the sensitivity but now when I push F6 key to disable, the icon you described keeps popping up every keystroke. These Lenovo guys are just useless and so sorry I bought this computer.

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

Satellite A210 touchpad scrolling disabled after Windows Vista update

Last week I accepted a Microsoft Windows update. Sine that update I can not get the Satellite to recognise its touchpad and the only driver updates that work are for a standard PS2 mouse. I can no longer use the bottom and side scroll features of the Toshiba touchpad. What drive am I looking for to rstore the touchpad please?

You can find the Touchpad driver here: http://eu.computers.toshiba-europe.com/cgi-bin/ToshibaCSG/download_drivers_bios.jsp
Firstly remove the driver from Control Panel -> Programs and Features
Then download and install the latest version.
If you have Logitech mouse drivers or other 3rdparty mouse/keybiard drivers installed, remove those as well.

Ethernet controller driver not installing after Windows Server 2008 installation on Cisco UCS blade

I am using MDT 2010 to deploy Windows Server 2008 to a Cisco UCS B200 blade. The OS and hotfixes install with no problem. The system reboots and attempts to connect to the deployment share to continue with the task sequence and I receive an error stating
"A connection to the deployment share could not be made. The following networking device did not have a driver installed. PCI\VEN_1137&DEV_0043&SUBSYS_00481137&REV_A2"
The driver in question is the driver for the Ethernet controller for the UCS blade. More specifically, it is the network driver for the Palo card in the UCS Chassis. When I Ignore or Abort the install, I am able to manually install the driver and restart the
task sequence. The build then completes successfully with no further issue. I just cannot seem to automate the driver install. Has anyone dealt with this type of issue?

Vik and stealthfield - thank you for your responses.
I was preparing a script to manually move the driver into the c:\windows\inf location when I had to stop to create a new task sequence for a different build. It was while building this task sequence that I found the soulution to the problem.
In the Post Install -> Inject Drivers step of the Task Sequence, I noticed that it was executing a command of type "Inject Drivers" with a selection profile of "All Drivers" and "Install only matching drivers
from the selection profile" selected.
I changed this to run a command of type "Run Command Line" and specified that it execute "%Scriptroot%\ZTIdrivers.wsf". I noticed that this was selected in one of my other builds that was working properly, so I thought I'd
give it a try. - IT WORKED.
So to sum up, the solution was to change the type of command being executed in the "Post Install -> Inject Drivers" step of the task sequence. After this change, the machine came up and continued the task sequence with no further issues.
Thanks again for the responses - They were helpful and I do appreciate it.

Beats Audio Control Panel software not working after Windows 10 upgrade.

Beats Audio Control Panel software not working after Windows 10 upgrade. the Beats sound enhancement is useless in WIndows 10. When opening the Windows 10 sound properties I'm getting this box message: Auido enhancement problem Windows has detected the audio enhancement for the following device are causing problems: Speakers / Headphones (IDT High Definition Audio Codec) Woud you like to disable driver enhancement for this device? IDT High Definition Audio CodecBeats Audio Control Panel version6.10.6491.02013.11.2009:43:18 Please provide some kind of fix for this?

Well, it has been a long road on the Win 10 upgrade. At first I got the same error message as above, but after deleting the Dolby Advanced Audio v2 in Win 10 using Control Panel Programs and Features and rebooting, I got into the continual BSOD upon reboot. Here are the steps I took to at least get stable on Windows 10. First, I rolled back to Windows 8.1 using the advanced feature in the BSOD recovery options. Once back in Win 8.1, I deleted the Dolby Advanced Audio v2 using Add/Remove Programs in Control Panel. Then I downloaded the Win 10 update and re-installed it. Once that completed, I updated the Intel Graphics driver under the display adapters (on my G780 it is an Intel HD Graphics 4000, and the driver can be found at https://downloadcenter.intel.com/). Currently I am running version 10.18.10.4252 for my machine. Then, under the Device Manager, I updated the Conexant SmartAudio HD driver under the Sound, video, and game controllers. That driver is currently at 8.66.4.50 and was automatically downloaded from the web when I requested to update driver. I also changed several others settings such as Notify to schedule restart after updates are installed instead of automatic (under Settings --> Update & Security --> Advanced Options) and Do you want Windows to download driver software and realistic icons for your devices? --> No, let me choose what to do, never install driver software from Windows Update. After that, I shut down the machine, waited a moment and booted back up. I have no idea why this helped or if it is overkill, but I am stable and running without a fear of rebooting now. Hope this helps if someone else is having this same issue.

My laser jet 100 color MFP M175nw is not working after windows 8.1 upgrade,

my laser jet 100 color MFP M175nw is not working after windows 8.1 upgrade, driver on your website fails to setup at 83 % with an error message

Welcome to the HP Forums MillaMagia,
I see by your post that the USB isn't being recognized.
I can help you with this issue.
Are you using the same USB cable? (known good USB cable)
You want to use the normal USB slot 2.0 cable and not the latest USB 3.0.
USB 3.0 are supposed to be backwards compatible.
Try another USB port on the Laptop, some of the USB ports are more powered then others.
I have provided a document to see if the printer is partially recognized in the device manager, which is causing the printer not to be recognized again. (the uninstall from the CD should have removed the entry and the printer from the registry)
Leave the printer turned on and the USB cable connected directly to the computer and the printer's power cord directly into a wall outlet.
How do I get into Windows Device Manager?
Here is a document for Identifying problems in Windows Device Manager.
Check to see if there are any hardware driver conflicts, you might see a ! mark or a red x beside a device with a conflict or unknown device, look under universal serial bus controllers, look for USB printing support or mass storage device, delete the entry by right clicking and select uninstall, OK.
Let me know how it was listed. (screen shots welcome)
If this is a Laptop then check the power management settings.
Access the device manager. Windows 8-How do I access the Device Manager.
Select universal serial bus controllers from the list, for each USB root hub, right click and left click on properties, for power management remove the check mark for "Allow the computer to turn off this device to save power". It allows the computer to limit or turn off power for this device.
Disconnect the USB, run the full uninstall and reinstall the printer software again.
If you need further assistance, let me know.
Have a nice day!
Thank You.

I was using windows login (single admin user) and fingerprint reader to login to my Thinkpad T510. Yesterday night I changed windows password and I didn't update finger print. Unfortunately I am not able to login when I tried to login using windows login today, I forgot the password and when I tried finger print reader it is just throwing error.
Why finger print is not working after windows password reset? What should I do to login?
Help would be appreciated!!

I just called the tech support just now? I just asked the 'why the finger print reader not recognizing the finger print after changing windows password?', and he gave the following answers
1. You should change fingerprint while changing windows password. I don't understand the reason behind it, btw is this true?
2. We can't do anything for this issue.

ipod will not sync after mcafee vulnerability scan installs itunes update?

When I tried the first time it asked me if i wanted it to stop syncing and to restore. It gave the choices of yes and cancel, i didn't click either because the option box went away and it just stopped restoring on its own. I did the store again and now it is asking if i want to set up as a new ipod or to restore to Andrea's ipod. Should I set up as new?

Synatics Touchpad V7.5 settings not saving after Windows 10 update.

After I updated to Windows 10 it seems that all dirvers were updated as well. Now the settings won't save everytime I shut down my laptop. Can someone help me with this please?

Hi, I noticed this has been a widespread issue concerning HP laptops upgraded to Windows 10 that come with Synaptics drivers. Here is a fix I found: 1. Open Device Manager and uninstall the current driver v19.0.25.95 and tick the box that says delete the driver software for this device. 2. Open Programs and Features and uninstall the Synaptics program you see in there. 3. Head to your product page in the HP website and download the Synaptics drivers available for the OS version your laptop had prior to the Windows 10 upgrade. In my case, it's Windows 8.1. 4. Restart your computer. 5. Install the driver you downloaded from the HP product page of your laptop. Verify that the installation has finished, you need to go through the Device Driver Installation wizard. 6. Once again, open Programs and Features and check if a new Synaptics program is displayed there; its version should match the version you installed from the HP website. 7. Once again, open Device Manager and check if the Synaptics Touchpad driver changed. If not, you will see an option to Roll back to a previous version, click this and the driver will revert to the version you installed from the HP website. 8. A prompt will appear asking if you want to restart the computer now or later. Choose restart later. 9. Download this troubleshooter from Microsoft and refer to this link on how to use it. The troubleshooter, hides updates and when updates are hidden, Windows chooses not to install them. Link- http://reviews.gizmodo.com/heres-the-incredibly-hacky-way-to-disable-windows-10-up-1720768012 Troubleshooter- https://support.microsoft.com/en-us/kb/3073930 10. Once you have located and have hidden the Synaptics update, Try changing your touchpad settings through the Control Panel and reboot to check if it saves the settings you have chosen. I have found this as a better and safer alternative than completely disabling Windows automatic driver installation.

Satellite Pro U400-15I - Sound Wheel not working after Windows 7 install

The sound wheel on my Satellite Pro U400-15l does nothing after the Windows 7 clean install from XP pro.
I used the recommended Software update tool downloaded from Toshiba. The VolumeIndicator.exe process is running and the sound works OK - just not under the control of the wheel! Also the Toshiba Power control is not there but this is not a problem.
Any suggestions welcome.
Bob Sheppard

Hi Syntax,
there is no option to add the volume control to the taskbar in the control panel.
The sound driver is 'Conexant High Definition Smart Audio 221'
Interestingly, when I click on the speaker icon on the taskbar and select the mixer option I get 3 sliders called 'Device','Applications' and 'Sound Volume Indicator of Toshiba Control'. If I move this slider with my mouse I get the indicator I am looking for ( The Toshiba indicator I had under XP). However, this slider only works as a 'minimum' for the other sliders.
Thanks for your help but I still would like that volume indicator back!

Partition couldn't be modified after uninstalling Windows consumer preview

I uninstalled Win Consumer Preview on my Macbook (Lion) using Bootcamp. An error showed up just as it got done. Since then, the Partition couldn't be modified because it contains CoreStorage physical volume. Help!

MSI GS70 20D Touchpad not working after login when I upgraded to 8.1

Short situation: I upgraded my laptop to windows 8.1, and the touchpad stopped working on the start/desktop screens. I could move it before I logged in, and after it would work for a few seconds, but then it would just stop. An external mouse works just fine, but I still don't want my touchpad not working.
I looked on the MSI USA technical support page, and it said to delete the old drivers for the touchpad and download new ones. I deleted the drives, but every time I try to download the new ones, I get a window that says my touchpad isn't plugged in, and that the drive isn't compatible with my touchpad, which doesn't make sense to me because I looked up my product specifically and tried all three touchpad drivers. None of them worked.
Now I can't use the touchpad at all because I deleted the drivers, so it would seem that the computer doesn't know it has a touchpad because it won't register the touchpad in my devices tab.
Does anyone know what I can do to solve this? Or to at least get the touchpad to register again? I just got this computer for Christmas, I've treated it very well so it hasn't banged up against anything or been dropped or mistreated, so I cannot understand why this is happening. It worked before the 8.1 update, so I'm pretty sure the issue has something to do with that.

UPDATE: So I managed to fix the touch pad by deleting the driver and rebooting, which is weird because I removed the driver completely and never reinstalled it, so the computer shouldn't really know it has a touch pad. But every time I reboot the computer after fixing it, the touch pad goes back to it's old problem and I need to redelete and reboot all over again.
Also, My computer has begun to randomly freeze and not respond to anything, with one such event leading to a blue screen with a WHEA_UNCORRECTABLE_ERROR message. The computer has frozen a total of 6 times, at different moments; when I'm typing on microsoft word, at the login screen, even right when it starts up and the msi loading screen is up. 5 of these times have required a forced shut down, the first time the computer shut off on it's own because it ran out of battery power.
Finally, my computer has begun to periodically for long stretches of time stopped detecting wireless networks and is asking to be plugged into an ethernet cable to connect to the internet. This has never happened to me before, and I know I haven't turned off my network sharing center.
I'm not sure why this is all suddenly happening. It's not like I'm banging my laptop against walls. I'm very careful when I move and use my GS70, so these problems are greatly concerning to me because I just got this computer at Christmas.
