Hi Chris, I doubt there are many less knowledgable than me but if it helps any one, that's good.
The laptop I have is a Medion Erazer but it isn't easy to find details of the exact model, so I'll paste them here in the event it's important info:-
Medion Erazer X6823 (MD98254) MSN30014987
CPU: Intel Core i7-3630QM
GPU: NVIDIA GeForce GTX 670MX
RAM: 16GB DDR3
ODD: Blu-ray ROM/DVD RW (Plus & Minus)
Display: 15.6" Full HD
WLAN: Intel Centrino Wireless-N 2230 with built-in Bluetooth 4.0 function
Battery: 9 Cell
O.S.: Originally Windows 8 since updated to Windows 8.1 and Windows10 Home.
The only problem that I have encountered since upgrading to Win 10 has been the incompatibility of the Synaptics touchpad with their latest Windows 10 driver which is automatically installed.
The HID Identifier for the Touchpad is :- ACPI\VEN_SYN&DEV_1507 : ACPI\SYN1507 : *SYN1507
An older Driver which works fine with this hardware under Windows 10 is:-
Seems Synaptics are not hosting that link anymore, found another source here, seems clean:- https://www.techspot.com/downloads/drivers/essentials/synaptics-touchpad-windows-10/
and I have several copies squirreled away, ...just in case, and they come in handy since unfortunately, Windows Update insists on installing the latest driver which whilst it may be compatible with Windows 10, does not work with the touchpad.
I have attempted to stop Windows Update from updating this particular driver, but the instruction is just ignored.
I know there is the facility to request Windows to "Never Update Hardware Drivers" which I feel is not in anyone's best interests so I'm not sure if that too would be ignored!
After Windows Update has done it's mischief, the offending driver should be removed prior to installing the correct (older) one.
I had initially thought this should be done via the Driver tab on the properties window in Device Manager, but this is not an option, only "Uninstall Device", which I don't think would have the desired effect!
The correct way to remove the driver is via Programs and Features: Shutting down and waiting 10 minutes before rebooting, ...some times it takes two or three reboots before Windows will acknowledge that this has been done to its satisfaction!
Double clicking on the drivers ".exe" file to start the install wizard followed by another re boot after it has finished, and all should be well.
...until the next major update!
