Yikes, my Toshiba touch screen stopped working!!!

I bought a hot new Toshiba notebook computer at the end of the year, a Toshiba Satellite P50-AST3GX2, with Windows 8.1. I even paid an extra $200 to get a touch screen. The machine works great, but a couple of times a week the touch screen stops responding. Everything else about the machine still works, but I have to use the track pad and keys to navigate and make selections. I still don't know what cause the touch screen to stop working, but I do have a quick workaround. Sure, of course you can shut down and reboot the machine, but that's too inconvenient.
 
What's the workaround for a touch screen that is non-responsive? Simple: Just toggle the Wi-Fi mode twice. That's the F12 (or FN+F12 keys, depending on whether you have function keys enabled). In my case I modified the function key configuration so that just pressing the ley labeled with both the F12 and Wi-Fi labels is the same as the old-style F12 key, so I need to press the FN+F12 keys to toggle airplane mode. Press FN+F12 once to toggle airplane mode, wait a couple of seconds until the popup message confirms the new airplane mode, and then hit FN+F12 again to toggle airplane mode back to what you really wanted it to be. The first press of FN+F12 is what resets the touch screen and restores full touch features. If you haven't changed the function keys settings, just use the F12 key alone.
 
In short, in takes a couple of seconds to re-enable the touch screen by toggled FN+F12 twice, but that's hardly the biggest annoyance in my life these days.
 
I really like the touch screen a lot.
 
The one thing I don't like about this machine is that since it is a "hot" i7-based machine, it has a bigger and bulkier power adapter which is a pain for travel.

I have a Toshiba NB10t-A. It's a newish netbook kind of number with a touchscreen. The touchscreen stopped working for me, and I immediately started browsing the net to see if anyone else had the same problem. You did. And your solution worked for me (I turned airplane mode on and off twice and the touchscreen started working again). So this is not an isolated problem. You should contact Toshiba and Microsoft both and let them know.

Bless you. I have a Toshiba Satellite S55T A5334, and it has done this intermittently since I turned it on. I had contacted their support when it first happened. They recommended a reset to factory settings and then a whole bunch of F2 and F9 restart etc...
I searched and searched and knew it was a simple fix.
Thank you.

FTR - if any one else with a Toshiba has volume keys stop working - go to the start > search for > function key > toggle both the "keyboard backlight" and the "touchpad" on and off.
