Windows 10: Surface Pro 4 Pen will not write on screen

My Surface Pro 4 Pen which I got with Surface Pro 4 has stopped writing. I can connect pen with Surface Pro 4 and and all works except I cannot write on screen.
I suspect it is the tip of pen that does not work but cannot verify this.
Please note tip is not broken.
Before I purchase a tip kit can someone suggest what I can try to see if it is the tip or something else that is faulty.
My surface Pro 4 is up to date with all updates including BIOS updates. I use a Windows 10 Fall Creators Update.
Thank you.

Try the tips from Microsoft Support at https://support.microsoft.com/en-us/...ft-surface-pen. In my case when this happened, I needed to replace the single AAAA battery inside my Pen. Perhaps you might find some of these suggestions helpful.

I solve problem.

This problem impacted customers after installing the Fall Creators Update. Also pinch to zoom fails as well with this problem

Other people have found that going into device manager and disabling/enabling the "Intel(R) Precise Touch Device" in device manager made both the pen and the multi-touch work again. When restarting, problem may probably re-occur.

Open device manager, Click on human interface devices to expand it and it should be near the bottom of the list. This is a temporary fix and the issue may return, but for now, it is the only work around. Microsoft engineering asked that anyone affected with this use the Feedback Hub App to send in a bug while in the bad state before disabling/re-enabling so that they can get the logs.

Hope this helps everyone who has this problem.
