Asus T100/T200 Touchscreen Not Working? Here's a Solution!

I almost had a panic attack when all of a sudden the touchscreen in my brand new Asus T100 tablet/laptop hybrid stopped working. It is just two days old and it had worked just fine the first day.

I had installed some new apps from the Windows Store to my laptop. Then, I updated the drivers and installed some more updates for Windows. After about half an hour of Windows Update, it restarted. And all of a sudden, I can’t use the touch input anymore.

Asus T100 Touch Screen Not Working Anymore?

Read The Context and Follow What May Apply To Your Situation:

I immediately snapped the keyboard dock and logged in. Everything works, everything is fine – except the touch display. Most of you might find the events relatable to my situation:

  • Did the touch stop working after you restarted the tablet and not just instantly when it was on?
  • Did you install any apps before restarting?
  • Did you install updates from Windows Update or Microsoft Update?
  • If you are using Windows 10 and you suddenly cannot use the touchscreen after you wake the tablet back after putting it into Sleep mode?

My situation is all of the four. Either one or all four has made the touchscreen non-responsive.

Given that Asus T100 and T200 are one of the best laptop-tablet hybrid devices for their price in the market, one would expect that they can run fine and the users won't need to be annoyed with small problems at every Windows startup.

Here's a small list of problems one can face in Asus T100 and T200 at any time:

  • Touch screen not working
  • Touchpad not responsive
  • WiFi Adapter stops connecting to the network
  • Touchscreen/touchpad driver goes missing overnight

How To Solve T100/T200 Touchscreen problem

First of all, don’t panic. I can assure you that it is not your fault, and your Transformer Book is probably not a defective one. Many users have reported the same issues on Windows 8 and Asus forums, which all boils down to one single problem—the miscommunication between the OS (that is, either Windows 8 or Windows 10) and how it allocates power to individual systems (in this case – the touchscreen, which is one of the components of Human Interface Devices)

I, personally, had this problem the day after I bought it. At first, I thought it was due to a defective unit that was accidentally shipped to me. After some research, it was clear and evident that hundreds of others reviews complain the Asus customer service of the touchscreen complication.

Solve the T100/T200 Touchscreen Issue With One Simple Trick

  • Go to your computer’s device manager. It can be accessed by typing “Device Manager” in the Start Screen.
  • If you want to reach the manager without any shortcuts, you can also access the device manager window through your PC settings. In the desktop, right click on My PC. Select Properties and go to the “Device Manager”.
  • If there is no "My PC" in the desktop, just start typing "PC" from the Windows 8 Start screen itself.
  • Toggle the I2C Device on and off. To do this, right-click on the device, then click Disable. After the screen refreshes, right-click on it again, then click Enable. Be cautious not to uninstall the device, as it would require you to install the touchscreen driver otherwise.
  • Your tablet should start responding to touch input.

There is a simpler step-by-step procedure for fixing the causes of touchscreen mess in both T100 and T200. This complication has not yet been reported by many in the Asus T300 Transformerbook, but if the problem appears, it can be solved with this simple step.

Make Sure it Doesn't Happen Again

Get The Latest Asus T100 Drivers

If you somehow uninstalled the device or the driver needs to be re-installed, the drivers for all hardware of Asus T100 can be downloaded at the official Asus website. Drivers for both Windows 8 and Windows 10 (32-bit) are available for download there.

Protect The Touchscreen

It might also be possible that the display screen of your tablet has a layer of water or oily film which is blocking the touchscreen. This is especially possible if you use it in a very steamy and humid environment, or after you have washed your hands and haven’t dried it off completely. These can be prevented by using a screen protector.

How To Solve Touchpad Problem

Turns out, if your touchpad in the keyboard is also not working, you can toggle the input device on and off. This will make the touch pad start working again.

Here’s the procedure:

  1. Check if the touchpad driver is not corrupted. Type "Device Manager" in your Start Screen and click on the first option that pops us. Check if any of the input devices is disabled or turned off.
  2. Check if you accidentally somehow turned the touch pad off. In the T200, the option to toggle the touchpad is in the F9 key. Press the Function key (fn) + F9 key and check again.

What About The Problem in Windows 10?

Windows 10 on Asus T100 has not been the best experience for me so far. A good thing about upgrading to Windows 10 is that I haven't had the occasional touchscreen issue. A bad thing is that when it does happen, the reason is pretty clear.

  • Whenever you close the lid and turn it back on, boom—the touchscreen is gone! You have to follow the steps again to revive the touch.

ASUS Transformerbook T200 is one versatile notebook, but just like its T100 counterpart, it can suffer from minor glitches and software problems. The Transformerbook series is no stranger to problems in network adapter, drivers in auxiliary hardware and problems in its keyboard touchpad and in the touchscreen display.

Other Solutions if The Touchscreen is Still Not Working

  1. The touchscreen of your Asus T100 might have been accidentally calibrated in an error. To fix this issue, you should try to reset the whole calibration. Move your mouse cursor to the top right, then move it down. The charms should then appear. Click on Search. Now, type calibrate and click on Calibrate the screen for pen or touch input. Click Reset on the window that opens.
  2. Inside the Human Interface Devices, there are four USB Input Devices. Right click on all of them, and go to Properties. Head over to the Power Management tab, and then deselect the option to allocate power. Finally, restart.
  3. If the problem still persists, update all the Important Updates and Optional Updates under Windows Update
