I have tried the computer reset and installed the windows again, updated the chipset drivers,ACPI drivers and scanned the hardware in the Device manager but nothing worked
HID Complaint Touch Screen is not showing up under the Human Interface devices and also the backlit on the keyboard has disappeared.

So weird. If you were to check device manager, are there any devices which the driver is not yet installed? (unknown devices)
Also have you installed all the Intel Chipset drivers? All the Lenovo utilities?

I have installed all the chipset drivers and there are no unknown or hidden devices in the device manager. there is an error icom on 12C HID Device and in the properties it says A requesrt for the HID description failed and the trouble shooting isn't fixit it and the message is trouble shooting has found no solution.
HID touchscreen disappeared once before as well but when I did the system restore it showed up again but last time I did the system reset it has completly disappeared.
Thanks for your time
