What should I do if the touch screen of surface pro7 is not responding?

This problem may occur because: There are many possible causes, ranging from calibration to hardware or firmware. Troubleshooting can find the root cause.

#1. Clean the screen

Clean the screen by moistening a soft lint-free cloth with water or eyeglass cleaning fluid, but do not directly Spray liquid on the screen.

2. Restart Surface

Note: You will need to connect a keyboard or mouse to Surface. You can use the Surface Type Cover or a USB or Bluetooth keyboard or mouse.

Sometimes just a reboot is needed to get your touch screen back to normal:

In Windows 10/8.1:

1). Press the Windows logo key. (If you are using a mouse, select Start.)

2). Press the Tab key and the arrow keys to select Power, and then press Enter. (Using your mouse, select Power.)

3). Use the arrow keys to highlight Restart and press Enter. (Using your mouse, select Restart.)

3. Install the latest updates

Note: You will need a keyboard or mouse connected to your Surface, as in the solution 2 in.

The touch screen may not work because it does not have the latest updates. Please follow the steps below to check for updates. If your Surface doesn't restart automatically after you install the update, restart it manually. To restart your Surface, go to Start, select Power > Restart.

In Windows 10:

1). Press the Windows logo key. (If you are using a mouse, select "Start.")

2). Press the Tab key and the arrow keys to select "Settings" and press Enter. (Using your mouse, select "Settings.")

3.) Select "Update & Security" and click "Check for Updates."

In Windows 8.1:

1). Press the Windows logo key. (If you are using a mouse, select "Start.")

2). Press the Tab key and the arrow keys to select "Settings" and press Enter. (Using the mouse, select "Settings.")

3). Select "Update & Recovery" > "Windows Update" > "Check Now."

4. Force shutdown

1). Press and hold the power button until the screen turns off (about 10 seconds), then release the power button.

2). Press and release the power button to turn Surface back on. You should see the Surface or Windows logo.

If that doesn't work, use this two-button shutdown process to ensure your Surface shuts down completely (not applicable to Surface RT, Surface 2, and Surface 3).

Here's how:

1). Press and hold the power button on your Surface for 30 seconds, then release the button.

2). Press and hold the volume up button and power button simultaneously for at least 15 seconds, then release them. The screen may flash the Surface logo, but continue to hold both buttons for at least 15 seconds.

3). After turning on the button, wait 10 seconds.

4). Press and release the power button to turn your Surface back on. You should see the Surface logo.

5. Disable and enable the touch screen driver

Note: You will need a keyboard or mouse connected to the Surface, as in Solution 2.

If the two-button shutdown does not work, please try:

In Windows 10:

1). Select the search box in the taskbar and enter "Device Manager" , then select Device Manager in the search results.

2). Select the arrow pointing to the left of "Human Interface Device".

3). Right-click "HID Compatible Touch Screen" and select "Disable".

4). Right-click "HID Compatible Touch Screen" and select "Enable".

NOTE: This may be more than one HID compatible touchscreen listed. If so, complete steps 3-4 for each.

In Windows 8.1:

1). Press the Windows logo key. (If you are using a mouse, select "Start").

2). Press the Tab key and the arrow keys to select "Settings" and then press Enter. (Using your mouse, select "Settings").

3). Enter "Device Manager" in the search box, and then select "Device Manager" in the search results.

6. Reinstall the touch screen driver

Note: You will need a keyboard or mouse connected to the Surface, as in Solution 2

If Disabling and then re-enabling your touch screen driver does not work, please try the following:

1). Select the search box in the taskbar, enter "Device Manager" and then select "Device Management" in the search results device". Same as solution 5.

2). Select the arrow pointing to the left of "Human Interface Device". Same as solution 5.

3). Right-click "HID Compatible Touch Screen" and select "Uninstall".

NOTE: This may be more than one HID compatible touchscreen listed. If so, complete steps 3-4 for each.

4). Restart Surface.

When you are connected to the Internet, your Surface will automatically download and install the touchscreen driver.

7. Download driver package

If you find that there is no "HID standard compliant touch screen" driver in the device manager, you need to download the corresponding version of the driver package for surface to install it. To learn how, see the following link:

8. Reset Touchscreen Calibration

Note: You will need a keyboard or mouse connected to the Surface, as in Solution 2.

If solutions 1-7 don't work, recalibrate the touch screen:

1). Press the Windows logo key. (If you are using a mouse, select Start.)

2). Type "Calibrate," use the arrow keys to highlight "Calibrate screen for pen and touch input," and then press Enter. (When using a mouse, select Calibrate screen for pen and touch input.)

3). Press the Tab key until the Reset button is selected, and then press Enter. (When using a mouse, select Reset.)

If the Reset button is grayed out, your Surface touch calibration remains at factory settings. Go to "Solution 9".

4). Press the Tab key until the Yes button is selected, press Enter, and follow the on-screen instructions. (When using a mouse, select Yes and follow the on-screen instructions.)

5). After your Surface deletes the recalibration data, test the touchscreen to see if it responds appropriately.

9. Check for electromagnetic interference

Sometimes other nearby electronic devices can interfere with the touch screen, or cause the cursor on your Surface to move around unexpectedly. The interference may be as simple as a nearby power strip or desk lamp, or it may be something like a large piece of equipment or a row of computers.

1). To determine if this is the problem, move your Surface to another room, another building, or outside. If the touchscreen problem occurs only in specific locations, there may be electrical interference.

2). Turn off all other devices in the area and turn them on one by one to identify the device causing the problem.

3). If no interfering device is found, check whether there is a more powerful device in the next room causing electronic interference.

10. Restore or reset your Surface

Note: You will need a keyboard or mouse connected to your Surface, as in Solution 2.

If you are still having issues with your touchscreen, try restoring or resetting your Surface.

11. Get your Surface serviced

If the touch screen still doesn't work after following these steps, your Surface needs service.
