Touch Screen Stopped Working | Acer Iconia Tab W500

Mine hasn't started working.  I did a refresh on my system, but nothing worked.  I tried reinstalling all the drivers, all over again...NOTHING.

Now reinstalling System w8Pro 32bit... Can't believe, only had this system for a week.

And already had, the famous blue screen of Death twice!!  Because I was force to, 'force restart' (holding power button).  Of course, my touch screen wasn't working... and NO physical hard buttons.  No choice but to force reboot.

I will report an update in my situation after the reinstall.  But if anyone has any other advice, please post it up.  Thanks in advance

If this issue is due to OEM version of windows 8 requiring windows 8 ceritified hardware, to disable this problem in windows 8 try the following:

Windows Key + X, choose Command Prompt (admin).  Then type the following two lines:

bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS

bcdedit -set TESTSIGNING ON

That should get you past the signing issue.

This fixed the issue for me but left a watermark in the lower desktop saying TEST MODE,

fixing that is a different google search.

Ok Method 1 came up with these results:

Problem detected with Unknown device

Details

Device type: Other Devices

Manufacturer: Unknown

Location: Port_#0001.Hub_#0003

Device Status: Windows has stopped this device because it has reported problems (Code 43)

Problem not fixed

Method 2:

Followed all instructions result: Error: Install Failed! Touch Module Driver

Any more suggestions. I'm confused why it worked before then suddenly stopped

I have the same problem. tried these methods, but there is no result :(((

sorry for bad English :D
