    Good evening,

     

    It is quite strange. I have the same problem. I have reinstalled Win 8.1 64 bit. The topuchscereen was working during the installation, but as soon as I reboot an upgrade is applied (I can see the reg changes at boot), and then the system panel clearly staes that the system does not have touch capability.

     

    This is really frustrating because the the touchscreen was working in Windows 7 and during the installation of Win 8.1.

     

    I have tried to install the egalax driver in compatibility mode (I hope I did it the right way) but I still don't have touchscreen.

     

    This is really frustrating. I would appreciate any help given.

     

    regards.

    Hope users of 1825PTZ running WIN8.1 are still trying to find the solutions, because one user from a Taiwan discussion board found the solution quite some time ago (http://www.mobile01.com/topicdetail.php?f=232&t=3685866).

     

    Windows 8.1 system update likes to install [CANDO - Input - CANDO PCAP Multitouch Digitizer], which is apparently not the correct driver, and ruins the touch capability.

     

    The solution is to uninstall that device from Control Panel while selecting 'Remove' the drivers at the first dialog menu (bottom left) appearing after the unstall command. After system restart, the touch functionality should work again. Please share your experience if you find this useful (or not).

    BTW, Windows tends to install drivers provided through Windows Update and undoes the changes made, so it may be necessary to turn off automatic driver installation through Windows Update (instructions such as http://support.microsoft.com/en-us/kb/2500967 or http://www.tomshardware.com/faq/id-2165451/dont-windows-windows-automatically-download-device-drivers-icons.html)

    Sorry I don't read Chineese... Thanks for the tip. 

    I will try it and see if it allows to use Win8.1 on that computer that is really great. It would really be a waist not to be able to install the latest Windows.

     

    I was hoping an alternative driver for Win8.1 would be available.

    The trick is to revert the HID (human interface device) driver back to the default USB HID something driver (I don't have my 1825PTZ with me now and the translated Chinese descriptions of device drivers are slightly different) installed during Windows installation. Delete the CANDO thing and the system will use that default USB HID driver to allow touch to work.

     

    I'd also like to share a trick to extend the life of 1825PTZ. Swap the hard drive for a new SSD (the newer the better; use hard drive backup utility such as True Image to transfer the system (WD, Segate, and Intel all have limited edition of that software)), and you breathe new life into this convertible laptop (despite the lousy creaking hinge).

     

    Please share your experience if the tricks work. Hope it will continue to live into the era of Windows 10.
