inspiron 5548 touch sreen not working

Hi,

Please confirm if the touchscreen is working fine outside the OS.

Run a thorough hardware diagnostics, Once the diagnostics are done, Use the touch input to select the devices listed on the screen.

Check if that responds.

To enter diagnostics, Keep tapping F12 on the startup Dell logo that comes as soon you press the power button.

Select "Diagnostics" from the list, Run it completely

Thanks.

Hi!

Thanks for the advice, we tried your suggested method, before the OS, the touchscreen is working. Any suggestions where to find drivers for it?

Extra information: the touchscrren worked with win8.1 but now the installed os is win7. (The user wants to keep win7)

Hi,

Please use the link www.dell.com/support to get the list of drivers for this model.

Before downloading the drivers, Please check if HID( Human Interface Devices) is listed in "Device manager" , If yes, ensure they are enabled.

And this one too

Thanks
