Has anyone experience a period of time when booting up that the touch screen doesn't work? After booting, it takes about 20-30 seconds before I am amble to unlock the screen; it won't even detect the pen.
Yes, I've had that to happen once on my Surface Pro 2, and a few times on my Surface Pro 3.
Touching the Windows Button on the bezel will sometimes get it back going.
Most times I've had to use the touch pad on my TypeCover in order to select reboot.
After rebooting it, everything works fine again.
I've always had it to happen when the TypeCover was attached. Not sure if there's a bug or something.
I hace 3 days without touch screen in my Lenovo lynx tablet. I think the problem was an update, when I restart I couldn't use the touch screen. I don't know what to do. Just a mouse connected to USB is the only way to use this tablet right now
Try uninstalling/reinstalling the touch screen driver.
Search "Device Manager" and run it.
Under the "Human Interface Devices" tree right click the "HID-compliant touch screen" and uninstall, then reboot. It should find the touch screen on reboot and reinstall the driver.
