Ideapad (Flex 15) touchscreen not working on upgrade to Windows 10

I have an Ideapad Flex 15.
Since I upgraded yesterday to Windows 10, I have lost the touchscreen ability I had up to that point on Windows 8.1. On search for pen and touch, I was given this message on a system information page: "No pen or touch input is available for this display." I have looked in device manager under Human Interface Devices. Expanding the view to show hidden devices, I see "HID compliant touch screen." When I click to get device status, this is the message:
"Currently, this hardware device is not connected to the computer. (Code 45) To fix this problem, reconnect this hardware device to the computer."
How do I do that? I note a similar problem in Windows 8.1 on this posting:
http://answers.microsoft.com/en-us/windows/forum/windows8_1-hardware/touchscreen-not-working/c48cda23-93f2-4a9a-b6da-f7f47e67de0a
Does anyone have any idea how to reconnect the hardware device -- or at least to solve this problem? Thanks!
Mod's Edit: Added model to Subject line for clarity

I took this in to a shop, and two technicians tried to solve the problem to no avail. One of them did as suggested, and uninstalled the touchscreen driver under Mice and other devices, but that only disabled the mouse touchpad. So it was reinstalled, and the driver for the touchscreen under Human Interface devices was reinstalled, but none of it helped, and I still lack the touchscreen capacity I had before. I cannot scroll except on the side ribbon, and I cannot use the touchscreen to zoom in and out, which I could do on Windows 8 and 8.1. So it seems there is no new Lenovo driver for the IdeapadFlex 15 that is compatible with Windows 10. I am told to wait and see, and to hope that Lenovo addresses this problem. BTW, I previously had two Microsoft tech people remote control my computer to fix this, and they both failed. I am disappointed with Microsoft and Lenovo. Any computer that was bought within the last couple of years fitted with Windows 8 should upgrade no problem to Win 10.

I solved the problem here for my sister's Flex 14.
Press Windows+X and open Device Manager, go to Mouse and uninstall USB touchscreen.

Re: NB200-134 - FN key not working after upgrade to Windows 7 Ultimate

My FN keys of NB200-134 is not working after upgrading from Windows 7 starter to Windows 7 ultimate. I tried installing every drivers found on Toshiba website for my lappy but still it does not work.
Help please

Hi asalamk,
The FN keys are controlled by Value Added Package and Flash Cards Support Utility. I think you have forgotten to install these tools
You should check the Toshiba page again and download both tools. Start with installation of Value Added Package then restart your notebook. After this install Flash Cards Support Utility. Once again restart and all FN keys should work properly now.

Touchscreen stopped working when upgraded to Windows 8.1

I have an HP Pavilion Product EOK22UA#ABA and Model 14-1027cl (I think?) and when I upgraded to Windows 8.1, the touchscreen has stopped working. I've looked through the forums and I can't find someone with the same Product/Model as me and I'm trying to find a solution to this. I do not want to do the "Refresh your PC without affecting your files" because I have programs on my computer that I cannot get again because they were downloaded on education licenses (I am a college student) and I can only download once. Any suggestions on how I can get my touchscreen up and running again? Thanks.

Hello @s_jensen,
Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I understand that the touchscreen on your notebook computer has stopped working since upgrading to Windows 8.1, and I would be happy to assist you in this matter!
Since your system may still have an older version of AMD graphics drivers installed on your computer, I recommend uninstalling the Windows 8 graphics drivers and installing the compatible ones for Windows 8.1. To do this, I recommend removing the drivers in Programs and Features and the Device Manager. Once the old software is removed, please restart your computer.
The drivers for your graphics card and touchscreen can be downloaded below:
AMD High-Definition (HD) Graphics Driver and

Dolby Home Theater v4 not working after upgrading to Windows 10

Hi there, I just upgraded to Wndows 10 Home from Windows 8.1; everything went smoothly except for the fact that Dolby Home Theater v4 does not work. I had to reinstall it using the .msi file found in the Realtek Audi folders. I chose v4 over any of the other versions because I like how I can tune the equalizer to my liking and different uses. Anyways, the regular audio works and Dolby is turned on but there is no activity appearing on the equalizer and my music does not change once adjusted. Had this problem when doing an optional audio driver update in the past when I was running 8.1. I do not have the option to rollback the driver after upgrading to Windows 10. Does anyone have a solution to this issue or know what the correct Realtek driver is to make Dolby work? This is one of my favorite features of my laptop and I really want it up and running again! Thank you in advance! JakeStiebs My unit: Lenovo Ideapad Z580 running Windows 10 Home with Realtek Audio Driver 6.0.1.7535

one more thing. I was not able to download cleanup tool/online scanner too. but may be it has something to do with my internet bandwidth. and other strange thing i observed is that before restart i was not even able to turn off all security features. but after restart that problem seems to be corrected.

Microphone not working after upgrading to windows 7 on Compaq Mini 730EA.

My Compaq Mini 730EA came with Wins XP and I have just upgraded to Wins 7 Ultimate 32 bit. My Mic is not working with Windows 7, but it can play sound. When I roll back to Windows XP the mic works, but does not with Wins 7.
Where can I get the appropriate driver for the mic, please. Not driver? Then What should I do?
Thanks much in anticipation.

Since there isn't a driver to download the only thing you can possible do is delete the windows driver that the notebooks installs for the feature.
This is what it will look like.
Go under Human Interface Devices and delete every USB INPUT DEVICE.
Then restart the notebook and it should install the drivers back.
Also, you can follow this document. http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01926155&tmp_task=solveCategory&cc=us&dlc=en&lc...

Keyboard wireless key not working after upgrading to windows 8.1

Hello,
I am having hp pavilion dv6-6165tx notebook, where keyboard having a wireless button that turns ON and OFF all wireless devices, After upgrading to windows 8.1, HP Connection Manager is not getting installed, as well as Key is not working, key color turns red and white but no action is performed.
Kindly suggest me some solution.
Note: HP Doesn't provide drivers for windows 8/8.1 ONLY WINDOWS 7 for hp pavilion dv6-6165tx.
Thanks.

Hi @Jayesh_Bhadja ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your HP Pavilion dv6-6165tx Notebook and the Wireless keyboard not working correctly. Here is a link to troubleshoot the keyboard.
The HP Connection Manager is something that is for Windows 7 not Windows 8.1. I would uninstall this from your Notebook. 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. It has a troubleshooting tool in this.
Make sure all your updates have been completed. I would try restarting my Notebook a few times.
If that does not help I would uninstall the keyboard from the Device manager.
Thanks.

Ethernet LAN not working after upgrading to windows 8.1

After upgrading from Windows 8 to 8.1, my Ethernet LAN is no longer working. Wireless LAN connectivity is OK. I have run the HP Support Assistant and downloaded the drivers for 8.1. Hovever, I do not see a 8.1 driver listed for the Ethernet LAN.

You're very welcome. See if the recovery manager still works so you can roll back to W8. Please read this guide for how to use it. http://support.hp.com/us-en/document/c03489643 If it doesn't then you will have to order a set of recovery disks from HP, or you can install this plain W8 OEM software this guy has posted on a link. Lots of folks have used it successfully, which is why I posted it. https://docs.google.com/file/d/0B0W9PBigPy94aVJWSndyTFNFMzg/edit?pli=1 Then use this tool to make the iso file bootable to a DVD or 4+ GB USB flash drive. http://www.microsoft.com/en-us/download/windows-usb-dvd-download-tool Yes, that really stinks why you and I could not upgrade without an issue. I disabled about 5 or 6 devices in the device manager and the code 12 would not go away. I have no clue why the PC works fine on W8 but not on W8.1. My notebook is a few years older than yours and it worked fine on W8.1 but not on W10. Go figure...

Bluetooth Not Working after upgrading to Windows 8.1

My Laptop is HP Pavilion G6 2015 tx after upgrade to windows 8.1, bluetooth is not working also the battery drain has increased anyone know a fix atleast for bluetooth problem ???

You're very welcome.
That is very interesting, because I didn't know of anyone who upgraded to W8.0 with a Ralink wireless card with the BT 3.0 radio that got the BT to work at all.
We tried the W7 drivers, and they didn't work.
That is why you don't see a W8 Ralink BT driver for the bluetooth on your PC's support and driver page amongst the other 11 drivers listed.
The Ralink 3.0 version of BT is not supported in W8.
While somehow the BT has worked in W8 for you, I'm afraid your luck has run out.
Unless by some fluke, HP installed a card with the BT 4.0 radio on your model...
You can try this W8 driver for the Ralink card with the BT 4.0 radio, but don't get your hopes up.

Hp dv6t select edition headphones not working after upgrading to windows 8.1

So I upgraded to windows 8.1 from 7 and now when I plug in my earphones there is no audio. I can still hear something when I just use the laptop speakers, just not with earphones. I also don't see the beats audio program on my laptop anymore or the hp support assisstant.

Hi @parjinder82 ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue of the Beats Audio not working correctly since you did the update for Windows 8.1 on your HP ENVY dv6t-7200 Notebook. Here is a document to check some settings that might be and issue with the software.
Sometimes the updates have not completely finish. I recommend restarting the Notebook as if there are some updates that have not gone through this will finish them.
You could check what is installed by checking here:
1. Right click speaker icon (right hand corner)
2. Select Playback devices
3. Right click Speakers
4. Enable it and set as Default
5. Click Apply/Ok
You might benefit from this document on Windows updates and sound issues.

Hello theow,
Welcome to the HP Forums!
I understand the touch screen on your notebook is not detected after updating to Windows 8.1.
This would be the best place to start: Troubleshooting Touch Screen Issues in Windows 8. This is a great document that covers touchscreen issues from start to finish. Do not be alarmed that it states the document pertains to TouchSmart PC's, as the steps are the same.
It would also help to know which product you are using so I can give you more detailed information, such as driver downloads.

USB 3.0 ports not working after upgrading to Windows 8.1

I have an Asus WIndows 8 laptop that I just upgraded to Windows 8.1 today. My USB 3.0 ports have started acting up. At first they recognized some of my external hard drives but not others. I tested all of the external hard drives and they work fine on my
other machines. I've tested the wires as well. Now, when I plug my external hard drives into the USB 3.0 ports, none of them work at all. All of them work fine on the 2.0 USB port though. How can I get my USB 3.0 ports working again?

my logic is like this, this motherboard is tested by Operating system that listed at download driver, you can check here
http://www.msi.com/product/mb/970AG46.html#/?div=Driver&os=Win8 64
there is an update 1.16.12 for USB ASMedia USB 3.0 Driver but for Windows 8
In order to worked with Windows 8.1, you need the updated driver, because this motherboard comes before Windows 8.1 launched
try to apply this registry trick, please don't applied hotfix since only applicable with Windows 8 and Server 2012
