This is Dell Inspiron 15 7000 Series 7568 fully convertible (2in1) touchscreen laptop which I purchased from BestBuy during mid-June 2016. To get rid of touchpad issues (cursor jumping erroneously), I disabled touchscreen functionality few months back. I went into Settings and disabled something which I don't remember exactly. Now I am trying to revert back to touchscreen mode, I tried all options but no luck. I even restored my PC back to original factory settings, still touchscreen is not working.
Could someone please suggest what could have gone wrong?
I'd suggest updating the System Setup(BIOS). Please click on the link below to safely installed latest BIOS version onto the system.
Warning: Do not turn off your computer or disconnect from your power source while updating the BIOS or you may harm your computer. During the update, your computer may restart and you will briefly see a black screen.
If updating BIOS doesn't fix the Touchscreen:
Please select Detect Drivers in the link below. The Dell utility will search latest drivers (Chipset and Video) for the system.
Yes I do see that. I disabled/re-enabled, not working. I deleted and restarted my PC, windows automatically recreated the same, still not working. I think I tried pretty much everything related to software (BIOS, Drivers, Firmware, Windows all are up to date).
I do see plenty of similar postings in this forum and my issue exactly same to:https://www.dell.com/community/General/Inspiron-15-7568-touch-screen-not-working/m-p/5094140
This is so frustrating that the important feature of my laptop stopped working after 1 year as soon as warranty expired. Probably I am not going to purchase any more Dell laptops.
Please right click touch screen driver in device manager, select "Properties", and then check in the status box if there's a message that says.....
"Currently, this hardware device is not connected to the computer. (Code 45) To fix this problem, reconnect this hardware device to the computer
Also, select Power Management and uncheck boxes by Allow This Computer To Turn Of This Device To Save Power, and Allow This Device To Wake Up The Computer. After, restart or power off system.
If you don't see the message and the boxes are uncheck:
Find USB Input Device under the Human Interface Devices. If there are more of these, you might have to repeat it for all of them:
1. Right click USB Input Device, click Properties, and then select Power Management
2. Uncheck Allow This Computer To Turn Of This Device To Save Power, and then restart / power off system.
