Hi @vnod ,
What OS is installed in the laptop?
Go to ''Device Manager'' and check if the touchscreen is OK.
If you have Win 10 installed, right click on the Windows Start button on the left side of the Taskbar and click on the ''Device Manager'' link.
When is ''Device Manager'', scroll down to ''Human Interface Devices'' and click on the ''>'' symbol to the left to expand the list.
If the ''HID - Compliant Touchscreen'' entry has a red cross next to it, right click on the entry and select ''Enable'' and check if the touchscreen works
If the ''HID - Compliant Touchscreen'' entry has a yellow exclamation mark next to it, right click on the entry and select ''Update driver software'' and follow the prompts. The laptop has to be connected to the internet for this to work though. Once the drivers have been updated,restart the laptop and check if the touchscreen works
If there is no fault symbol next to the entry, right click on the entry and select ''Properties > General'' and view the status of the touchscreen in the Device Status box. Does it say ''This device is working OK''
