Problem with G500s Touch Screen

I'm experiencing a problem with my G500s Touch, i am not touching the screen but it makes a lot of random inputs and appears contextual menu (like right click). It's really annoying, one of these days i'm going to throw this laptop through my apartment's window.
I already opened device manager and deleted all HID interfaces and reinstalled. Reinstalled Elan Drivers (i think maybe it is the problem, elan driver), i used windows restore 3 times and i still have the problem.
A Quick solution for this: Ctrl + Alt + Del, then Escape. And you will not have this problem in the next 1, 3, 5 or 10 minutes.
Please, if you have solution for this problem.
Regards.

hi sishio,
From your observation, it looks like the Touchscreen is malfunctioning.
Can you try the following
1. Under the Device Manager > Human Interface Devices, can you do a right click and disable on anything that says HID-compliant device (this is the driver that controls the touchscreen).
2. When finished, reboot the system and observe if you still get the same issue.
If the problem gets fixed, you may need to contact lenovo and report your findings as you may need to send the unit for service.

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

Are there any other left eye dominant (or left handed) iPhone users that experience problems with the touch screen keyboard selecting the letter next to the one you'd intended..?

Are there any other left eye dominant (or left handed) iPhone users that experience problems with the touch screen keyboard selecting the letter next to the one you'd intended..?

It's either hand right or left.
I have the same issue myself. Not sure if it's b/c my fingers are too big or if I'm really missed the letter on the keyboard.

Serious Problems with Iphone Touch Screen

Hi,
I am facing following issues with my Iphone. Could you please help/guide me how to get them resolved
1) I think some portion of the Touch Screen has stopped working. For e.g. when i type the message in normal mode then SEND button is disabled even if i try 10 times i am not able to send the message.
Therefore, as a work around i need to tilt my iphone to widescreen mode and then tap on send...it works....but it is very irritating
2) Many a times Iphone on its own dials the numbers in the contact list/recent dialled/missed call
3) If i leave SMS screen open for some time, then it automatically starts typing characters randomly
4) The same behavior is also there in Ipod i.e. it own its own changes the song
These are the main problems which i am facing ,,,anyone else facing similar issues?
I have already tried following things
1) Restarted the iphone n number of times but to no success
2) I have also tried reset option
Please help me how can i get these issues resolved pls.

Have you tried a restore in iTunes?

Problem with multi-touch screen when lid is closed

I have a T400s with the MT screen, running a clean installed Win 7 32-bit and all latest Lenovo drivers/BIOS.
I use external screen/keyboard/mouse at work so I am used to have the lid closed. I set in power management in the way that closing the lid does not do anything (e.g., sleep or hibernate).
The problem is: when the lid is fully closed and external mouse is used, the mouse cursor randomly moves and clicks. When random clicks happen, I can see the finger-tap animation near the cursor on the external screen, suggesting that the MT screen receives input even when the lid is closed! It might be heat from the palm rest/keyboard area causing fake taps.
Leaving the lid slightly open (like 15 degrees) solves this problem.
EDIT 1: another clue of the above problem is that while the lid is closed, Windows 7's tablet input panel shows up on the left edge, which typically appears after a tap or a tablet pen gets close to the screen. I also noticed that the random clicks take place near the right edge of the screen.

@ wesleyyin,
certainly strange. Some questions to help with the diagnostics;
Which TrackPoint cap you you have on your keyboard, soft domed, soft rim or classic domed (the hairy one)?
Can you try disabling the TrackPoint to see the problem goes away?
Anything else laid on top of the system or between screen and keyboard like a thin cloth or something?
Thanks

I'm having problems with my touch screen in Safari

Shortly after downloading iOS 8.0, I started having trouble with my touchscreen when in Safari. Note: I am not necessarily attributing the problem to iOS 8.0--just stating when it began to occur.
Touch commands began to not work with certain buttons on certain websites. Often, the websites seemed to freeze up. I could sometimes get the touch commands to work again if I refreshed the page.
My most frustrating encounter happened this evening, when I tried to make a purchase from a retail website I use frequently. I could use the touchscreen to accomplish all the steps in the shopping process but one: I could not get the "cart" button to work, so I could not get to the checkout screen. I refreshed and rebooted. I even downloaded iOS 8.1 and tried it again. Nothing worked. Finally, I used my wife's iPad Mini to place the order. My wife has not downloaded the new iOS 8 (neither 8.0 nor 8.1). Again, I am not necessarily implying it worked on her iPad Mini because she had not downloaded the new operating system--just stating that she had not done so.
Any idea what might be causing this? It does not appear to be a hardware problem, as my touchscreen seems to work fine in other applications.

DId you try clearing Safari, force close it and then reset the iPad?
Go to Settings>Safari>Clear History and Website Data
In order to close apps, you have to drag the app up from the multitasking display. Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the app that you want to close and then swipe "up" on the app preview thumbnail to close it.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Problem with the touch screen

All buttons but phone, email, safari, and ipod work but these 4 do not.
Do i need a new one?

If a reset doesn't restore full function, then try a restore. If a restore doesn't work then yes, a return and exchange is in store.

HT2907 How do you stop inadvertent contact with the touch screen? Why no Lock Button? Doesn't anyone work out at Apple?? MY Gen 7 also doesn't link to workout equipment automatically like my Gen 6 and I can't stop the bloody voiceover. Any thoughts?

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Big problems with my touch!

Hello everyone
About a month ago I had purchased an 8gb iPod touch. Last night I had a plane ride and I noticed I could hover over the screen with my finger and the screen would react to it as if I were touching it, but as if I was jerking it up and down...
I'm not sure if that makes the best sense but it's the best way I can describe it.
Does anyone know what caused this and or how I can fix it? Any help would be greatly appreciated.
Thank you

I'm pretty sure thats not an actual "problem". My understanding is that the touch screen works not by touching as by disruption of a static field on the screen. It is possible to interact with the touch screen without actually touching it. You can hover your finger over it (albeit very close to touching it) and still launch apps and control things as if your finger were in direct contact with the screen.

Since I installed iOS7, during calls my cheek interferes with the touch screen

since I installed iOS7, during calls my cheek interferes with the touch screen, switching on FaceTime or speakerphone

That is the bug, exactly. Phone rings, slide to answer, raise to ear to use as a telephone!
Getting infuriating. "Reset All Settings" worked for over a week for me, then problem returned.

Problems with Ipod Touch

Problems with iPod Touch.
Hi, I bought an ipod touch in Colombia a couple of months ago but lost the invoice, I tried using it but everytime I connect the iPod to the computer, it restarts over and over again, I've tried all the recommendations show in the Apple support site, but no method has proved the question is, I can take this ipod to a Mac store in the U.S. for repair or change.
I live in Venezuela, there is some Apple store in my country where I can take it.
Thanks in advance for your quick response

You should be able to go to the USA for warrantee service. If you purchased at an Apple store you should be able to go to your account in iTunes and see the purchase. I am confused by your statement:
"I live in Venezuela, there is some Apple store in my country where I can take it."
If you go to the Venezuela apple website you can see if/where there are Apple stores.

Will an iMac mini and mountain lion work with a touch screen monitor?

I was wondering if Mountain Lion would work with a touch screen monitor. I have a project in mind and this is a key part to the equation. If any one could help this would be greatly appreciated. Thanks in advance.

I do Not know for certain, but from my understanding, touch screen interfaces require that the OS version used to drive them be "designed" from the beginning to operate within that environment. Obviously, at this point OS X has Not been designed to function that way (non of the Mac's using it work that way); although the mobile version, iOS 6, used in iPhones and iPads was indeed designed from scratch to operate that way. So one day sometime down the road it's possible that OS X too will share this ability. But not yet.
Hope this helps

Why my ipad have problem with the rotation screen

i have a problem with the rotation screen is locked, i try everything but nothing is happening help

If you see a lock icon in the upper right corner of the screen - then the screen orientation is locked.
Try the side switch above the volume rocker first and see if that unlocks the screen. If that doesn't do it, double tap the home button and swipe to the right and look for the lock icon all the way to the left.
If the screen is unlocked but still will not rotate, reset the iPad.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the button
