Windows 8.1 Samsung Chronos series 7 touch screen has become unresponsive

hi - the other day after several months of absolutely normal operation, my Samsung Chronos NP780 Z5E T01UK touch screen became unresponsive - it simply didn't react any more to touch. I trawled the internet for what could be at fault with little success. Then I tried a couple of things, in Device Manager to do with putting hardware to sleep to power save, and then I managed to find a way to recalibrate the screen and low and behold it then worked... for a bit... since then however I later had a couple of BSOD equivalents where the machine simply turned itself off and rebooted... and since then nothing I try will get the touch screen back - I've downloaded every Windows 8.1 update, I've downloaded all the available Samsung software, including the graphic driver at 800mb and the Touchpad driver, done everything and still no joy. In fact, I now think that the laptop doesn't even realise it has a touch screen because when I manage to get the Search box up in the right hand of the screen and type 'Calibrate' which I think is what I successfully got to last time, the relevant entry 'Calibrate the screen for pen or touch input' no longer appears.  Grateful for any ideas, thanks

UPDATE: I was rooting around in Device Manager wondering why I couldn't even see the touch screen listed as a Human Interface Device. Anyhow, I found the ability to reveal hidden devices in the menu at which point I saw, in feint font, 'HID compliant Touch Screen' in the list. I went into that and saw  'Currently, this hardware device is not connected to the computer. (Code 45)' To me this is reflective of / an explanation of the above behaviour, the machine doesn't even see the device yet I haven't dropped the machine or anything to cause a connector on the inside to come loose...

Is your machine under warranty?  I would say (based on your description above including driver updates) that your screen is faulty. It could be the connector or the screen itself.

Does the computer have a VGA output and if so can you try a different screen.

I think it probably still is, but I would have a work continuity problem so would want to be certain that there is no other solution. I do have a VGA output which still works fine and indeed my main monitor also works fine apart from the total lack of touch screen functionality...

You have tried drivers so short of a fresh install of Windows (consider getting a test hard drive), I am not sure how you can prove the issue.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Totally agree. Best would be a second installation, this could even be done to the same hard drive, into a VHD file like shown here: http://blogs.technet.com/b/haroldwong/archive/2012/08/18/how-to-create-windows-8-vhd-for-boot-to-vhd-using-simple-easy-to-follow-steps.aspx
