windows 8.1 - My Dell Venue 11 Pro loses the touch screen

My Dell Venue 11 Pro loses contact with the touch screen from time to time. I can pop it onto the keyboard and continue working, but the only way to get touch back is to completely recycle the power. Very annoying. I'll go dig through Device manager and the event viewer to see if anything obvious is happening, and whether there's a service I can recycle to get touch back, but does anyone have any idea why this is happening?
This issue was addressed in a new firmware and driver issue in February of this year. I can't find the exact article which told me this, but I had to patch a friends Venue11 and it fixed it.
Alternatively, there are a couple of other things you can try:
1)Warranty - Venue11s are fairly new and most are still in warranty - Dell will replace the device if they cannot identify the problem immediately.
2)Services. Take a look at services.msc for any services with the start type "auto" and the state "stopped" next time it crashes. This will help you identify any potentially halting services.
3)Reinstall chipset, touchscreen, bios and video drivers - always a good idea with this type of problem.
4)system restore to a time when you know this was working
5)windows updates - there could be a newer signed driver, service update or other patch out there to help fix this issue
6)AV/AS scanning - if something is maliciously killing your touch screen interface - a good AV scanner will find it.
Hope one of these helps.

I have a HP Laserjet Pro 400 color MFP m475dw. I am running OSX Snow Leopard.
While I was cleaning dust from the control panel touch screen, it spontaneously decided to calibrate the touch screen (when swiping over the screen I probably got extremely (un)lucky). Problem is that I can't find any way to start the touch screen calibration from outside the touch screen control panel and the only way I've found to do a factory reset on the damn thing is through the menus in the touch screen.
Is there a magic dance I can do when restarting the printer to get it back to factory defaults, or better, anyway to start the screen calibration?
Update:
The touchscreen is totally out of whack, meaning that the locations I press on the touch screen don't cause a response in the same location in the printer. This means, for example, that to press "Settings" on the printer means pressing somewhere near the center of the touch screen. This also means that some buttons are (or at least, seem) totally inaccessible.

There should be "HP Solution Center" software on your PC that you installed the print drivers on, it can do most everything the touchscreen can do. Use the "settings" button at the bottom of the main screen.
Not sure what you mean by re-calibrate.
Here is the manuals page for that model printer

I was hopeless and I just clicked both side of the touch screen several times (Middle of both right/left side of the touch screen) as it is shown in the figure until I get a calibrating Setup appeared in the touch screen!
Then I followed the steps (Press on the Dots ● shown on the touch screen) until getting the Home Window of the printer. Hope this will help you :)

You have to press simultanously on the left side in the lower corner of the black space and on the right side in the middle of the black space, that's the trick I've found out after about half an hour testing! Now it works again!

With a newer firmware, the calibration is started from the integrated web configuration facility, which can be reached with the HP Utility on OS X, via the "Open embedded web server" button.
From there, navigating to System -> Service, there is a "Start calibration" button. Pressing this gave me the touch screen calibration screen on the printer and it actually worked this time.
