Problem touch screen IdeaPad U330

Hi!
I know this problem might be posted before, but I couldn't find it.. So I'm trying it this way.
Since a few weeks my Lenovo IdeaPad u330 has a problem with the touch screen. When I start my laptop, it works perfectly, but after a few minutes - or maybe an hour (it's quite random actually) the touch screen stops functioning, and I can't use it at all. I've used my laptop for over 10 months now, and the problem only started occuring a month ago, I think.
I think it might have something to do with the fact that my apps stopped working and that I had to 'restore the system'.
For the record, I'm still using Windows 8..
Anyone's got a clue?
Thanks in advance!

We've just started having a problem with the touch screen. The screen becomes unresponsive and while the trackpad works the cursor flickers so you can only see it while it's moving. After a bit of playing with it I realised that it was registering some presses at the bottom of the screen- you could see the touch feedback circles. If I moved the screen a little, holding it at the top, more or fewer touches registered, so it looks as if the screen housing is putting pressure on the touch screen. If you hold the screen just right then no touches register and it goes back to normal.
I'm just getting ready to return it. Probably try to get a refund because it looks like a design fault to me. Shame because it was a great laptop (despite windows 8)

Windows 8 upgrade problems (touch screen and audio)

my　computer is HP touchsmart 600 1005xt and recently upgraded from windows 7 to windows 8 (64-bit)
after up grading I noticed that the touch screen does not work and and the speakers also did not work

HI,
Here are a few tips that might help you to get your touch screen working:
Activate Windows and install updates by pressing the Windows logo key + W. Type "Activate Windows" into the search field, and then click on the Activate Windows icon that appears in the upper left corner of the screen. In PC Settings, click on Activate Windows, wait for your computer to connect to Microsoft, and then follow the onscreen instructions. Restart the computer. Press the Windows logo key + X, and select Control Panel from the menu. In the upper right corner of Control Panel, select Large Icons from the View by drop down. Click Windows Update. Install touch and/or graphics driver updates. Restart the computer.
Another thing to try: Go to the HP Support and Drivers site and click Drivers and Software. In the search field, enter your product name or number, and then click Next. Select your operating system from the drop-down, and then click next. (If you don't know if your operating system is 32- or 64-bit, press the Windows logo + X key again and select System from the menu.) Follow the onscreen directions to install any appropriate drivers. Restart the computer.
If the touch still doesn't work, try this: Press press the Windows logo + X key, and select Device Manager from the menu. In Device Manager, click the little triangle next to Display Adapters to expand the list. Right-click on the graphics card and select Disable. When asked if you want to disable the card, click yes. Restart the computer. You may have to tinker with your screen resolution.

Multiple problems: Touch Screen and Power Button on my Iphone 4S.

My power button on my iphone will click but it doesn't recieve any response from my phone. Also, my screen isn't working at all. The only button that works is the home button. The phone is only a couple of weeks old. I recieved it in the mail from apple and it has run smoothly up until now. It is a very random occurence and I would like to have it resolved quickly. Any suggestions?

First thing to try is to reset your device. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider should one appear until the Apple logo appears. Let go of the buttons and let the device restart. See if that fixes your problem.
Make an appointment at an Apple store to have the phone checked out. Or call Apple Support.

Torch 9800 touch screen only works when slid open.

Hello everyone, this is my 1st post but I've been lurking the forum for some time. I'm running a Torch 9800 on AT&T right now on v6.0.0.600
This is what's happened with my phone: as the subject notes, my touch screen only seems to work when I slide open the phone.
What I've tried so far that doesn't work: rolling back software, rolling the software forward again, hard resets, soft resets, adjusting intervals for the touch screen.
The weird part is that I saw an older thread that had the exact opposite problem(touch screen only worked when the phone was slid closed). I have a level/ruler app for my phone and it's showing that the phone knows when it's tilted/angle/orientation. I've also closed the phone, opened it slightly (about the width of my thumb) and it stays horizontally oriented + I'm able to use the touch keyboard that way.
Anybody have a suggestion as to what I can try next to fix this? I haven't gone so far as to just go and get a 9810 yet, but i'm considering it.

Thanks for the post.
Has it in anyway fallen or pressed hard at any point? It could be the belt, which would just need you to go with it to a certified repair center and get it secured.

Touch Screen Un-Responsive

Problem: Touch Screen not fully responsive at all times.
I broke one screen trying to answer calls before the ring sequence timed out.
After missing 7 calls over a few hour time span, I tried harder and harder presses on the screen.
Lesson learned - take it back anytime it hiccups. The phone was 5 to 6 weeks old.....
That phone was sent off for out-of-warranty repair.
The replacement (luckily I had a line up for upgrade) has the same problem, but not as severe.
The problem seems to be worse under high humidity weather conditions.
Problem: Repaired Phone now unable to be brought out of standby
The original arrived back from repair.
The screen was replaced, and the LCD was reported to be damaged in shipping, so it was also replaced.
The phone now will not wake from standby, under any circumstances. You have to remove the battery and restart.
I have the screen timeout set for 30 minutes. At least it lets me do some things via WiFi.
I have done a Full Reset, format SD Card and format Phone Storage.
I have also done a complete firmware reload.
Anyone have any ideas?

Yuy can try the standard fixes to rule out a software problem:
- Reset. Nothing is lost
Reset iPod touch: 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
- Restor to factory defaults/new iPod.
If you still have the problem that points to a problem like bad digitizer. Apple will exchange your iPod for $99, $149 or $199 depending upn the capacity.
A third-party place may be less expensive. Google for more places.

Problems with touch screen in ideapad U530

I Have a Ideapad U530. The touch screen worked a few hours, after having purchased and then I stop. I saw that had disappeared the "Pen and Touch" and Tablet PC in the Control Panel folder.
I went back to recover the system at the time had arrived from the factory and the laptop returned to work a few hours, this time with the Pen and Touch and the Tablet PC in the Control Panel. Then returned to stop working and disappeared again both drivers.
I need to find a solution to this problem.
Can I help me?

Hi Adrileb,
Welcome to Lenovo Community!
I’m sorry to hear that your U530 Laptop touch screen is not working as expected even after performing “System Restore” in the computer, I suggest re-installing display driver from our Support Website and check if the issue persists and while installing the driver right click on the downloaded file and select “Run as administrator” option to get it installed without any error. Below is the link to download the relevant drivers for U530:

Do post us back if the issue persists.
Best Regards

U330 touch screen randomly not working

My laptop is U330 touch. Recently, I found that my touch screen function randomly works. When I start my computer, it works but when I put my computer asid, after the turning off of display, the touch screen cannot work. And then I turn the computer off or turn to sleep and restart, the touch screen works again. Is that there any setting goes wrong? Can anyone teach me how to solve this problem?

Do you have a screen protector applied in which case try peeling it back?
If there is very high humidity where you are it might be worth immersing device in bowl of dry rice for 24 hours as in this thread: http://talk.maemo.org/showthread.php?t=44517

IdeaPad U330 shows a blue screen and then shuts down while trying to Backup using onekey recovery

I have a brand new Lenovo IdeaPad U330 2267-58U preloaded with Windows XP Professional. After I installed some application software I tried to use the Onekey Recovery (from the Start menu) to create a backup of my system partition (C drive) for the first time. For backup mode I chose "Full backup" and for Compression Type I chose "Quick compression" (I tried the no compression option and it didn't work either). I then clicked the "Next" button and left everything unchanged as the default setting (backup location set to the D: drive). As soon as I clicked the "next" button, and then the "start" button, the screen turns blue and the system reboots. The system then reboots with the blue disck-checking screen.
Any fix to this problem?? I haven't been able to create any back up for my system or create a recovery disc so far.

have you checked your disk(s) for error(s)?

Touch screen not working on Ideapad 11s

I just got my factory-refurbished Lenovo Ideapad Yoga 11s in the mail from Newegg today. I booted it up, everything works great except I am getting zero touch screen response. I looked at some other discussions and couldn't' find anything quite like this, it sounds like most of the problems were resulting after a few minutes of no touch input, whereas I am getting no responsiveness whatsoever from the get-go. So far I've tried restarting the computer, restarting 'ymc' in services within the Task Manager, and also tried adjusting the power saver settings on the USB Devices in the Human Interface portion of Device Manager. Does anyone have any further input on this? Thanks.

Hi Hannah,
if its a factory-refurbished unit and the touch keyboard won´t work.
I would suggest to do all Windows updates. If the problem remain send it back to the reseller, because it seems defect.
Best

Touch Screen intermittently working (IdeaPad S510p touch)

I have the IdeaPad S510p touch, which seems to have a similar problem as other Lenovo models where the touch screen seems to stop working intermittently. It seems to stop working after a while or after it has been sleeping. It starts working again randomly. I tried downloading a driver for a different model, but it didn't load or allow me to open it. I just got this computer a few days ago. I'm not sure if it is better just to take it back to the store, but I am concerned that this problem will exist even if I exchange it for a new one...

Hi john,
Sorry, I wish I had a better answer for you... we ended up just taking the computer back to the store and trading it in for a new one. We found when our touch screen stopped working, it seemed to be right after it slept... as opposed to starting it up after a complete power off. However, it was not consistent. We ended up trading in this model twice - now on our third one and it is not perfect (because the mouse clicks and moves when you are typing on the keyboard), but it generally functions so we kept it. When I first had this issue, the other problem was that we bought it from OfficeDepot and this model didn't seem to be available anywhere else and so there was very little information out there on how to fix problems.
Again, sorry. wish i could be more helpful with an actual solution...
thanks, J

Ideapad s510p touch screen stopped working

This computer is not even a week old. When this first happened I saw that on the bottom side of the laptop were two switches, one for the battery and I guess one for the touch screen, by the way there is not literature on what so ever, and after flipping the switch the touch screen worked perfectly for about a day. Now it has stopped working again, but the switch is in the correct position. All of my drivers are up to date. I am so frustrated with this. the mouse works fine, it is just the touch screen. Please, someone tell me you have had a similar issue with this series of the ideapad and that you have been able to fix it, I really don't want to have to send it in as I use it everyday for work.

Hi eking4044, welcome to the forum,
     Here is your user guide:
http://download.lenovo.com/consumer/mobiles_pub/ideapad_s410ps410ptouchs510ps510ptouch_ug_english.pd...
     Here is your HMM:
http://download.lenovo.com/consumer/mobiles_pub/ideapad_s410ps410ptouchs510ps510ptouch_hmm.pdf
     Both of those "switches" on the bottom are for the battery. One is a spring loaded switch to open battery, after you push the other one into the open position. This is how you remove the battery, and have nothing to do with the Touch Screen.
      Did you delete any of the software that came with your system? The easiest thing you could do is backup your user files to a CD, or some external hard drive, then reset your system using the system recovery. See page 20 of the user guide for the recovery routine. Make sure you have a backup of your user files, before attempting the recovery, as it will set up your system like new. This should solve your problem, but if it doesn't, please post back with further information.
Cheers

U430 Touch Screen not working on Ideapad

I just bought a new IdeaPad U430 laptop a few days ago and I love it. However, the touch screen doesnt work. I've looked through the forums and have tried a lot of things and none of it has helped so far. Using the f6 key on the laptop freezes the mouse but the touch screen doesnt seem to recognize my finger. Please help! Like I said, I love everything else about this laptop and I really dont want to return it.
Moderator Note; subject edited; system type added

hi graceella,
Welcome to the Lenovo Forums.
Ideally, the OS automatically identifies if you have unit with a Touchscreen or not. To check, look under Control Panel (large icon view) > System (see images below).
Non-Touchscreen:
- Link to picture
- Link to picture
Touchscreen:
- Link to picture
If the machine is showing No Pen and Touch Input:
1. The OS is not identifying the screen as Touch capable. To isolate, perform a System Recovery (via the OneKey Recovery button) to check if the issue is on the OS level (ensure you backup important files first).
If the machine is showing Limited Touch Support:
1. Recalibrate or Reset the touchscreen
2. Reconfigure the Touchscreen
If same problem,
3. Press the Windows key‌ +R, type devmgmt.msc and press Enter.
4. On the device manager, navigate to Human Interface Devices and uninstall anything that says HID-compliant device. When finished, reboot the system and observe.
5. After the reboot, press Windows key‌ +R, type mspaint and press Enter. On mspaint, try to touch the screen and observe if the touchscreen capability is working.

If the above steps doesn't resolve the issue, I recommend you contact Lenovo and report the problem (or the place of purchase if it's still possible to exchange the unit).

Problem push and hold on a Surface Pro tablet's touch screen

Hi,
I tried posting this before, but I can't find my origional post so I hope I'm not spamming accidentally.
I have a problem with my program on a Windows 8.1 Surface Pro tablet. I programmed a button to be 'push-and-hold', but when I touch the tablet nothing happens until I release my finger. This briefly controls the button. When I connect a USB mouse to the tablet, it responds normally; when I press the left mouse button: the button in my program goes down until I release the mouse button. I tried about every setting in the Touch section of the Windows control panel without any succes.
Does anyone have a suggestion?
Any help would be greatly appreciated.
Chris

My iPod Touch 3rd Gen is having problems with the touch screen being unresponsive, too responsive, freezing and constantly resizing. Is this a common problem? Is there a fix?

My iPod Touch (3rd Gen) is having problems with the touch screen being unresponsive, too responsive, freezing and constantly resizing. It varies between not responding when I tap the screen and acting as if I double-tap or tap and hold when I tap. Every so often it freezes for a minute or so and then comes back. The scren is constantly changing sizes too such that I often can't see most of the top status bar or other edges. This makes typing almost impossible, ruins most games and generally makes everything difficult, but otherwise the iPod is working correctly. Powering off, shutting down apps, letting it sit have not worked. This has happened once before months ago, but the issue resolved itself somehow. Is this a common problem? Is there a fix?

Try this for the freezing

Or if they don't work put it into recovery mode
