I'd suggest powering off system, remove all peripherals -printer, external drive, etc.), AC adapter, battery, and then wait about 5 minutes. Press 'Power On' button for 15 seconds to release Status Flea Power. Replace battery, adapter and then power on system. Hopefully touch screen is working now.

If the touch screen still isn't fix....

Please type Device Manager Control Panel onto [Cortana] search box, stroll down to Human Interface Devices and then expand it. At the Device Manager taskbar, click on 'Action' and then Scan For Hardware Changes. Hopefully touch screen is working now.

I hope the answer posted by LSUFAN51 on 19 Feb 2017 will solve your problem. If it's not solved, please check whether your computer's screen is diabled or not. If it is disable, please turn it to enable. For checking it, please follow the steps.

Step 1: Right click the Start button.

Step 2: Click Device Manager OR search for 'Device Manager' from the Windows 8.1 Start screen.

Step 3: Select Human Interface Devices.

Step 4: Find a device with the words 'touch screen. In my system, it is 'HID-compliant touch screen'.

Step 5: Right-click on it and select Enable.

I restored my laptop a week ago and it started working again but now the same thing is happening. I tried checking the device manager but there is no touch screen option. gyazo.com/6b42d9a5d52c71a131cbffaddfb16056 Another thing is I'm not sure where the battery is or how to remove it. www.dropbox.com/.../Photo Mar 04, 6 32 31 PM.jpg also ever since I removed the thing covering the battery and put it back in, I can no longer two finger scroll so that makes things even worse. Please help!

Hello so a week ago I restored my laptop and it worked but now its not working again. There is no touch screen option in the human interface devices and I don't know where the battery I'm supposed to remove is. Another thing is ever since I removed the thing that covers the battery and put it back on, I can no longer two finger scroll which makes things even worse.

If the touch screen doesn't appears, expand Disk Drives. Under Disk drives, right click the drive and then update it. Do the same for Display adapters as well.

Dell Inspiron 3543:

Please expand Human Interface Devices again, click on Action, and then 'Scan For Hardware Changes'. Hopefully touch screen driver appears under Human Interface Devices. By the way, windows 10 is on the system? If you don't know, type msinfo32 into the search box, you'll see the system information.

EDIT:

After you updated the Disk drives and Display adapters, expand Universal Serial Bus controllers and then look for any yellow exclamation marks. If there any yellow exclamation mark, perform the following steps:

1. Right-click or touch and hold on the listing that has the yellow exclamation mark and select Update Software Driver.

2. Click Search automatically for updated driver software, and follow the prompts.
