Built in microphone and touch screen doesn't work

Hi
I have problems with two things, my built in microphone doesn't record anything, also I tried all suggested steps of HP support.
Windows recognizes the microphone.
The touch screen doesn't work the touch part, but the display is working good.
Also i tried to update Drivers, but looks like Windows does not recognized the touch screen, when I going to Control Panel and search for touch screen stuff, I do not see anything.
I hope you can help me to fix this.
Thank you.

Hi @ldiego008 ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your HP ENVY TouchSmart m7 Notebook and the microphone and the Touchscreen not working correctly. If you follow this document it will show you how to correct this issue on the Touchscreen.
Try following this document document on Resolving Microphone and Line-in issues for Windows 8.1.
Here is something else that might help if you need it. If you go to the Device Manager (Audio inputs and outputs)and uninstall it from there restart the computer it should automatically reinstall it for you. This link shows you the Device Manager Screen shots that might help.
Hope this helps with both issues.
Thanks.

Cracked screen, home button and touch screen doesn't work

I dropped my phone from the 2nd floor and landed on the screen. My screen is broken, the home button doesn't work nor does the touch screen. What can be done? I really do not want to get a new phone

Front screen replacent at Apple Store is $149, it includes a new home button, so everything will be fixed with this. Make Genius reservation to avoid long wait time at Apple Store.

Do a reset, hold down the home/sleep button together until you see the apple logo and then release, then wait for the device to boot back up.
No data is loss doing a reset.

I have an iPod touch 2nd generation and my touch screen doesn't work, at all. What should I do?

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

Apple will exchange your iPod for a refurbished one for this price. They do not fix yours. I say not worth it for a 2G

A third-party place like the following maybe less. Google for more. Again, likely not worth it for a 2G

I cant open apps on my iPhone 4 the touch screen doesn't work. I have restored my phone and still nothing works.

I can't open apps on my iPhone. The touch screen doesn't work. I have restored it already but it still won't work. What can I do.

If the touch screen is not having any response then you probably have a hardware failure. Take your phone to an Apple Store or authorised service provider to have it checked.

My palm m105's touch screen doesn't work properly after a sync.

I dug out my old m105, put new batteries in and start it. On first launch it auto runs the alignment tool, and after touching all the points it goes to the main screen and works fine. No problem till here.
Now, I plug it into my old computer which still has the palm software with my apps, and I run the sync operation (from the palm device sync manager, cause I lost my cradle and I'm connected via the serial cable), and it syncs fine BUT, here comes the problem, when it finishes the sync (successfully) the touch screen is all misaligned. I can't go back to the home screen or do anything useful.

Maldoman578,
Let's help solve this mystery together! Is your screen freezing after every reboot? Is there any physical/liquid damage on the device? When did this issue begin? Did you notice this after a recent update or application download?

Touch screen doesn't work!!!

I got my TP two weeks ago, played with it for a day and a half then, in the middle of surfing the web, the touch screen doesn't work. I've contacted HP support and sent my device in for repair. I got it back two days ago (12/30/2011), worked totally fine for 20 mins and the touch screen didn't work again. I've tried using WebOS Doctor 3.0, 3.0.2, 3.0.4 nothing works.
I've tried rebooting it multiple times, still doesn't work. Frustrating I must say....
Any suggestions?

Gotcha, so I just want to make sure I'm following you correctly. At this point the screen is probably all black from the auto-turn-off thing. You hit the power button, and the little yellow lock icon appears on the bottom. But when you try to drag the little lock icon, nothing happens. Does that describe what's happening to you?

I cannot use my ipad2 because the touch screen doesn't work at all. First I cannot unlock it or do anything in the screen!!!! Why?

Have you tried a reset To see if that fixes it ? Press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

How can I back up an iphone when I haven't set the phone up for back ups & the touch screen doesn't work? The phone can receive calls (not answer) & the pictures & messages can be seen but the touch screen doesn't work to unlock the phone or select anything. We want to save/transfer pictures, contacts, and music to the replacement phone.

Try backing it up to your computer with iTunes. Connect it to your computer, open iTunes, click on the name of the phone in iTunes, go to the Summary tab of your iTunes sync settings and click Back Up Now. Also go to File>Devices>Transfer Purchases to transfer you apps and other purchased media to your iTunes library.

You need to do more research before you make purchases like this. You've wasted your money. The ONLY officially unlocked iPhone model sold in the US is the GSM model, and that model is only sold by Apple. That's the model iPhone you should have purchased.
Did you read & understand my initial post? Especially this part:
The unlocking of the GSM portion is just for International travel in order to use local sims. You still have to pay Sprint for the use of their international GSM partner’s network on a “pay as you go basis”.

Dropped my phone and now I see almost-transparent lines on my lock screen and the touch screen doesn't work. Help?

I was walking to my garage when my iPhone slipped out of my hand and fell on the floor. I looked at it and saw strange almost-transparent lines on my lock screen. I tried to unlock my phone, but it wouldn’t let me do anything. It was almost as the touch screen wasn’t working. I turned it off and plugged in my phone to the charger and it started up automatically, but it still looked the same and wouldn’t work. I think that my iPhone 5 might be broken? Please help!

Make an appointment at an Apple store and have then assess it

Touch screen doesn't work after Vista Home64-bit upgrade to Windows 7 64-bit Home Premium on IQ506

Hello, right before I upgraded to Win7, I made sure that the Touchsmart software worked and that the touch screen itself worked. As soon as I performed the upgrade (not the clean upgrade that wipes all your existing data, but rather the upgrade that carries over your applications and files), the touch screen ceased to work.
I didn't panic, thinking that I probably had to run some windows/hp updates, which I did to no avail. I also manually updated ALL the driver/software files found at this link http://h10025.www1.hp.com/ewfrf/wc/softwareList?os=4063&lc=en&dlc=en&cc=us〈=en&product=3752245
Yup, every single one. As a last resort, I tried some of the HP troubleshooting for touch screens not working. It said to shut down the computer, pull the plug on the computer, hold the power button for 5 seconds, plug the computer back in, and boot it up again. Didn't help at all.
I'm at the end of my rope and there is no additional HP support on this. I'm waiting for a reliable driver update for win7 for this **bleep** touch screen. I'm dead in the water -- I've got a touchscreen computer whose touchscreen doesn't work! Someone else out there must be having this problem! Any leads?

Did you try installing the Touch Driver?
