Touch Screen Stops Working

[jjaarr22622]

Recently my Touchscreen on my laptop just suddenly stopped working and I have no reason why? Any Suggestions for getting it back to work?

Do yo know of any physical reason for it to stop working? It does't need to be cracked to be broken obviously, but any hard hits or heavy weights on the lid could've done your digitizer in. can you tell us the exact model of your PC? it should be on a sticker on the bottom or you can just give the name on the front.

Update: I did a system restore and I noticed that the touch screen started working again when the laptop rebooted for the system restore options but then afterward the touch screen didn't work again so it's definitely connected and not broken in the inside it just doesn't want to work all of a sudden when the pc is on normally

Hmm, peculiar, have you tried reinstalling your touch drivers?Also check device manager> human interface devices> and then you should see some kind of touch screen listed, right click it and tell me what the options are.

When I go to device manager there is no human interface devices list like there should be. Instead the drivers are listed under other devices and say "Atmel maXtouch Control", "Atmel maXtouch Digitizer", and "Unknown device" without a caution triangle symbol while the first two do. Uninstalling and restarting the computer does absolutely nothing as I have tried multiple times but like I said before the system restore restart allowed the touchscreen to work and I have tried multiple times to make sure. I have no idea what's going on

The fact that they aren't under human interface devices isn't exactly concerning but those Caution triangles, if red, are. just right click them and try disabling and and reinstalling them if you haven't tried that already. If there is an update driver option that should do something as well, This definitely sounds like a strange software glitch not hardware but it is possible that you digitizer just went funky. Since its showing up in device manager its probably physically fine, so if reinstalling/updating its drivers don't do anything i would try testing with another operating system. Ubuntu for instance works well for this sort of thing and you don't even need to install it. Just download The Ubuntu 17.10 Boot Image from: https://www.ubuntu.com/download/desktop Then Move the whole thing onto a clean thumb-drive with 4GB+ of storage, then shut down your laptop and Boot it into BIOS, (Hold F2 down, click the power button and keep holding F2 until in BIOS screen) Once in BIOS use the arrow keys to navigate to the boot tab and select "boot order" it will open up a sub-menu that will have your hard drive, DVD drive and the thumb-drive, use the arrow keys to select the thumb-drive and use the +/- keys to bring it to the top of the sub-menu, press ESC and then F10 to save and exit. Start your laptop up with the thumb-drive still plugged in if it didn't start on its own, and let it boot into Ubuntu's Start menu. Once there select the option "try Ubuntu" with the arrow keys and it should boot into the Ubuntu desktop. Then just try out your touchscreen!

I figured it out! It was a windows update was causing the problem. The new KB4074588 update was the cause and it makes sense since it was recently updated. When I went online and searched this update, it came up with a bunch of news that there were major problems with people with this update and specifically was with the USB drives. I'm pretty sure somewhere with touch screen laptops that the USB is considered a USB device particularly from the device manager in human interface devices, there are two USB input devices installed. So my guess is that the update messed with it especially when other people are having issues with their USBs as well. I uninstalled the update and the touchscreen worked perfectly, which might explain the system restore restart having the touch screen work but not the os normally. I then reinstalled the update and made sure that the touchscreen worked and it did. I may include a picture in the next post of my updates cause it failed to install the update but the touchscreen was working even when it failed.

Awesome! mark this thread as solved and add Windows and OS tags this has probably affected a lot of people!
